Q u a s t , Supt., Milwaukee Country Club Milwaukee, Wisconsin It has certainly been an honor to be president during this Bicentennial year. It has been a pleasure to work with D r . Daniel, D r . Freeborg, and the Board of Directors, who all have a sincere interest in the growth of the Midwest Regional Turf Foundation. This has been a key turf foundation and members have been loyal to it since 1946. It is always nice to reminsce; however, we must not look at this as a turf foundation of the past but as one of the present and of the future. Time will bring forth many important names in the field of Turf Management, and from these people many new ideas for research. I firmly believe that with our continued support, much of this research will still be going on at Purdue. I believe, just as many of you believe, when it happens it will happen h e r e . You get as much out of something as you put in it. D r . Daniel has put most of his professional career in this foundation and its goals. Just like D r . Daniel, we must get involved, must be a part of* What greater tribute can you pay the Midwest Regional Turf Foundation than to insure its perpetuation? How do we do this? By joining, and after that by participating. Hard work put into this foundation by so many over the past thirty years should not be paid back with apathy. MIDWEST TURF CONFERENCE W . H . Daniel, Executive Secretary Purdue University More than 625 attended the 1977 Midwest Regional Turf Conference at Purdue University, February 28 to March 2 . Water Management was the central theme for the varied program. However, other timely topics were included, such as physical fitness, building machines to fill a specific need, artificial turf in the Busch Memorial Stadium, S t . Louis, reclamation of land as related to our energy resources, photograph aids in turf management, and promotion and teaching new golfers. Indiana Golf Course Superintendent's Association allocated $400.00 for Purdue student labor. This was announced at the banquet. This contribution not only helps individual students but supports research as w e l l . Other awards included the GCSAA Scholarship Award presented by Palmer M a p l e s , Director of Education, to Randy Bellinger ($500.00). Henry Lyons of the Upjohn Company presented scholarships of $250.00 each to Ken DeBusscher and Matt Lindner. Kermit D e l k , Superintendent of the Springfield Country Club, Ohio, was elected President of the Midwest Regional Turf Foundation Board. He succeeds Danny Quast of the Milwaukee Country C l u b , Wisconsin. Others newly elected are: Vice-President, Bud C a m p , Lebanon Chemical C o . , F t . W a y n e , Indiana; new Board members: John Morris, Highland Country C l u b , Indianapolis, Indiana; Tony Kramlik, Fort Wayne Country Club; Wayne Otto, Osaukee Country Club, M e q u o n , Wisconsin, and Dick Trevarthan, Prestwick Country C l u b , Frankfort, Illinois. Stan Frederiksen, Mallinckrodt Chemical C o . , Retired Ferguson, Missouri Thank you sincerely for the very real privilege of being with you again at yet another Midwest Regional Turf Conference. 1 D r . Daniel and D r . Freeborg really are 'past masters in the art of choosing flprovocative topics for 1their Turf Conference programs. And the one assigned to me - What 1 You Seek You Can Get - is certainly no exception. Each of them knows what it is to throw out a challenge, and it is a poor unmotivated individual, indeed, who won't respond with great relish to the kind of challenges these fellows provide for u s . Once upon a time a kind and understanding father, on a beautiful October morning, asked his eight year old son to go out into the yard and rake all the fallen leaves into a single pile. Little Joe w a s , to say the least, terribly upset, and for at least two reasons. First, the yard was h u g e , with leaves literally! covering it. Second, f Joe had just been savoring the idea of getting out with the g u y s for a game of touch football. With his fond hopes for some hours of fun now dashed, Joe glumly went outside. A half hour later, when Joe's Dad came out he found Joe sitting on the top step of the porch, with his chin cupped in his h a n d s , glaring intently at the yard full of leaves. "What are you doing?", said Joe's D a d . Joe replied, "I'm wishing - wishing for all those leaves to be in one big pile." "How are things coming?", asked Joe's D a d . "Terrible", said Joe, adding, "I've been here wishing for a half hour, and the leaves haven't moved." "You just aren't wishing in the right w a y " , said his D a d . "Now you watch this." Joe's Dad picked up a leaf rake and started raking the leaves. As he d i d , he kept repeating aloud the phrase, "I wish all these leaves were in one pile!" And guess what? In about twenty minutes all those leaves were in one pile. "There you are," said Joe's D a d . "See what I mean?" "Aha!", said J o e . "No fair! You were raking while you were wishing!" "Just so," said his father. "You can make any wish come true if you DO something to help make it come true." To say this another w a y , you can get whatever it is you seek - IF you DO the things necessary to get what you w a n t . Just what is it that you are seeking? Is it money? Is it better turf? Is it the acclaim of your membership and friends for a job well done? It is "status"? Is if Freedom? Is it the ability to 'get b y ' without working? Is it a trip to the moon? Is it to "reach the unreachable goal"? Whatever it1 IS, YOU CAN GET IT - IF (A), you set what you want as an absolute goal or 'target , and work ceaselessly toward it, and (B) you are willing to pay the price. The story is told of the famous woman concert pianist who had just concluded a really phenomenal performance before an audience consisting of the members of an exclusive Women's Club. Accolades and acclaim were given her by everyone in the audience. Women fawned over h e r . One w o m a n , in particular, was elaborate in her words of praise for the pianist, who was none other than the world famous Miss Gina Bachauer. Said this admirer, "I'd give anything to be able to play the piano like that!" To which Miss Bachauer replied, quite unexpectedly, "No you wouldn't." Seeing her well-meaning admirer was puzzled, somewhat embarassed, and more than a little h u r t , the gracious Miss Bachauer replied and hastened to comfort and reassure h e r . Said she, "Please don't be offended. I greatly appreciate your applause and acclaim. However, you said you would do anything to be a concert pianist. May I tell you that I learned middle C on the piano when I was so young that I don't even remember learning it. Since I was ten years old I have practiced on the piano not less than eight hours every single d a y , seven days each w e e k . Now think over your statement again. Would you be willing to give up eight hours every day for over forty years in order to perform as a concert pianist?" The admirer, with some humility, acknowledged that "No", she would not be willing. In other w o r d s , SHE WAS NOT WILLING TO PAY THE PRICE! One of the real prerequisites to success - to getting what you want - is to know what you w a n t . This requires that you adjust your focus upon this thing, or these things, that you w a n t . Are you focusing upon what's right there before you? O r , are you looking beyond the immediate, at the ultimate goal some distance down the road? A rather exciting article, titled "Marketing Myopia" appeared over fifteen years ago in the Harvard Business Review. As you k n o w , 'myopia' means 'nearsight1 edness or shortsightedness - the phenomenon of seeing what's right before y o u , but being unable to discern what's beyond, in the distance. In the article, the author chided just about all businesses for being shortsighted. But he took particular delight in 'needling' some specific businesses and industries. For instance, he said that the oil companies were so myopic that they continued to focus their attention on better gasolines and oils because they thought they were in the oil and gasoline business. "Wrong!", said the author. "They were in the ENERGY business." He went on to say that if the "oil" companies would just take a look, they'd find that the average American woman hates to go into a filling station, for any reason! She will almost be willing to run out of gas rather than drive into a filling station. For this reason, said the author, the oil companies should be looking, not for better or more efficient oils and gasolines, b u t , rather, for new forms of energy such as (for instance) solar energy, nuclear energy, and the like, so that any car owner c a n , if he or she wishes, replace their oil/gasoline engine with a simple solar cell, under the h o o d , and be able to drive some 45,000 to 50,000 miles on a single charge of the solar cell, without ever having to drive into a filling station for any reason! In the same article, the author said that the railroads, in about ten to fifteen years, would be essentially out of business, because their executives and senior corporate officers mistakenly believed that they were in the "Railroad" business. "Wrong again," said the author. They were not in the "Railroad busin e s s " , they were in the "Transportation business", the people-moving and productsmoving business! How right was that author? Just take a look at the fix in which the so-called "oil" companies find themselves, with few petroleum reserves, and very limited capital with which to explore for more such reserves. Then take a look at the sad plight of the "Railroad" business. Where are the railroads? Just about gone. f Why? Because the officers and directors of the railroad companies had Marketing f M y o p i a ' - they d i d n t look beyond the immediate future of that time, to what we presently call the "here and now". NO ONE WAS PLANNING FOR N O W , W H I C H , AT THAT TIME, WAS THE "FUTURE"! As a result we now have what? "Amtrak". And this is nothing more than a "has-been" in transportation - a people and materials-moving operation which has largely been supplanted by the trucks, planes, barges, and other forms of transportation, which are mostly self-supporting, while you and I are paying good tax dollars to subsidize what should have been allowed to die long ago - the inefficient, expensive and clumsy transportation form we know as 'railroads'. And all this because of "myopia" - the failure to look toward, and plan for, the ultimate target and goal - the FUTURE. You and I know many people, now in their chosen fields and professions, because they knew what they were seeking long ago, and they strove and worked toward those targets and goals. I know a young man of thirty who is a cardiac surgeon. It happens that he k n e w , when he was in the sixth grade, that he was going to be a cardiac surgeon And he never lost sight of that goal. On the other hand, we also know of both men and w o m e n , now middle aged, who still don't know 'what they want to d o , or be'. As a result, they keep floundering around, seeking what they choose to call 'happiness', never seeming to realize that true happiness is not an end result or goal, but rather the simple process of striving toward that goal! What you seek you can get? Is that a truism? You bet. One of the famous golf course superintendents is Bob Williams, of Bob-O-Link Golf Club in Chicago* Bob is one of the most astounding innovators and thinkers and doers I have ever known. He has been a superintendent for over forty years. Long ago he set his sights ahead, always ahead ! He established 'five-year plans' which are the model for similar plans at courses all over the United States. Each year he up-dates his five-year plan, to eliminate what has been done, or which has, for some reason, been removed from his list of goals, and he inserts in their places new targets and goals. He never loses sight of those goals, is always striving to make sure of their accomplishment. In the process, over the years, Bob has had another overriding goal - to up-grade the profession of the Golf Course Superintendent, and to train men to become top professionals in this field. Can any of you possibly imagine the satisfaction and downright happiness that must be Bob's right now, in 1977, as he 'points with pride' to one of his former employees and former 'students', Ted Woehrle, Superintendent of Oakland Hills Country Club at Birmingham, Michigan, who has been selected by his peers as President of the GCSAA? Such is another goal that Bob Williams and Ted Woehrle, too, have not only sought, but achieved ! Just how do you achieve that sometimes elusive 'success'? There are any number of w a y s . One is to learn every facet of the job above you, so that you will be able to 'take over' the minute your predecessor moves upward or vacates his position, or you are called upon to fill in for h i m . 'Go to school' on those you admire m o s t , seek to emulate them in every way you can. Educate yourself, as you are doing, indeed, by attending great educational conferences like this one. Practice humility, the art of realizing that no matter how much you k n o w , someone else probably knows just a little m o r e . Find out what that 'little more' is, and then learn it and make use of it. Be on the alert for opportunities. Someone has said that if you are doing something the same way you did it last year you probably are doing it wrong! What it means, in essence, is that opportunities in droves are confronting you all the time - to do something you didn't do at all last year - or to do something better this year than you did it last year. If ever you feel you are able to sit down with your feet on your desk and tell yourself, "Goodie, I'm all caught up", at that moment you are indeed on the down grade - heading for inferiority! Why do the really successful people succeed? First of all,,f they expect, and M work toward success. They don't know the meaning of the words, It can't be d o n e . Instead, when they encounter a 1 1 problem or obstacle, they ask themselves, "What do I need to do to get this done? Then they find out, and they do it.! Secondly, 1 they don't wait to be told what to d o . By and large, they are 'self-starters . They really challenge themselves! All of you know the story of the mountain climber w h o , when asked why on earth he determined to climb Mount Everest, said, "Because it's there." You and I know one of the greatest self starters in the entire world of Turf. His name is Tom Mascaro. It was his motivation, along with that of Drs. Jack Harper, Fred Grau, Bert Musser, Joe Duich, and others, that made possible the Pennsylvania Turfgrass Survey of 1966, w h i c h , once and for all, showed the tremendous value of turfgrass; in fact, proving that turfgrass w a s , at that time, the largest agricultural crop in the State of Pennsylvania! When health problems began to limit Tom's activities, he moved down to Florida. Did he just sit on his ' d u f f ? He did not. In 1974 the State of Florida published its own Florida Turfgrass Survey, showing the tremendous value of turfgrass in Florida - disclosing, in fact, that it ranks second down there only to the citrus crop. Take a look at the inside of one of the front pages. There, among the names of those responsible for bringing about that fine survey, you will find the name of (you guessed it) Tom Mascaro. Note that what Tom seeks, he gets! When success is elusive do y o u , like so many others, tend to place the blame for not attaining it upon others? At a sales meeting one time, one of the speakers invited each of the salesmen present (there were twenty-five in the group) to write down, and send up to him, a brief note giving the reasons why he lost a sale, or failed to solve a problem, or in some way fouled u p . Do you know that twenty-four men in that group put the blame on someone else? In one case, the fellow said, "I got the order, but the Shipping Department didn't ship 1it on time." Another said, "My boss just wouldn't give me the back1 up I needed. Still another said, "The laboratory made the specifications too strict, so that the material I wanted couldn't be produced according to specifications." And so it w e n t , until the speaker read one from the twenty-fifth m a n . In his brief note this man said, in effect, "Whenever I encounter a boo-boo or a problem or a bad situation, I've found, usually, that the fault was nobody's but my own! Either I failed to communicate what I wanted done, or I was a really poor motivator. In short, any time I didn't get done what I wanted done, I boiled it down to one thing - I was a lousy manager!" How many of us, here in this room, are ready to make such an acknowledgment? The other day, I heard on the radio, and then read in the paper, the story of a remarkable talk by M r . W . Clement Stone, w h o , among other things, has accumulated some four hundred million dollars, is happy in what he is doing, and certainly, in most of our tninds, must be considered a success. I would say, for example, that what he seeks, he gets! What's M r . Stone's secret for success? Believe it or not, it is "FMA"! He says that success is generated by FMA, and by this he means POSITIVE MENTAL ATTITUDE! Says M r . Stone, "What the mind of man can conceive and believe, the mind of man can achieve." I believe him. He says that it doesn't matter how high you set your goals, if you are willing to pay the price. And this doesn't necessarily mean in terms of money. Rather in terms of dedication, determination, and 1 plain hard w o r k . Remember, you can 'wish the yard full of leaves to be in one pile, IF you do some raking! It takes effort, along with the wishing. Most of us know what we want - and even how to go about getting it. Where we get bogged down is in our inertia, our almost complete lack of the very important element of success called motivation! Are you a real motivator? Are you a real 'self-starter'? If so, your success is assured because I'm sure you know what you w a n t , and how to get it. Making the very first move to start that process toward success is the tough one. Can you do it? Of course you can. What you seek, you can get! Just one more thing. It is important to do a bit of soul searching when you start your quest for success or continue the good start you've already made. May I suggest you ask yourself the question that I heard from Richard Evans when he was the commentator during the Sunday morning hour of music by the Salt Lake City Tabernacle C h o i r . During the discussion on how you determine whether you are on the right track, in your heading for f,success, M r . Evans said that every man should ask himself the very serious question, W0ULD YOU HIRE YOURSELF?" EDUCATION - WHAT IS IT ABOUT? Palmer Maples, Jr., Director of Education, GCSAA Lawrence, Kansas Someone said the only way to have an intelligent conversation is to first agree on the definition of all words that would be used in the conversation. Let's review some definitions: Education 1. The act or process of imparting or acquiring general knowledge and of developing the powers of reasoning and judgment. 2. The result produced by instruction, training or study. 3. The science or art of teaching. Knowledge 1. Acquaintance with facts, truths, or principles. 2. The body of truths or facts accumulated by mankind in the course of time, 1. The quality, production, expression, or realm of what is beautiful. 2. The class of objects subject to aesthetic criteria. 3. The principles or methods governing any craft, skill, or branch of learning. Art Science A branch of knowledge or study dealing with a body of facts or truths systematically arranged and showing the operation of general laws. Any skill that reflects a previous application of facts or principle. Teaching To impart knowledge or skill - to instruct.

Cooperation, coordination, and communication are the three basics of contact with every individual, employer, and employee. These are vital in relating with the professional, club manager, and club officials. What has all this to do with education? your relationships and responsibilities. We can say it is involved in all All people are uneducated about some subjects; all people are educated about some subjects in varying degrees. We are all ignorant - just about different! topics. As we go through life isn't it amazing how much we find that we d o n t know. Each individual has his own accumulation of facts and truths and skills which comprise his knowledge or education. The idea is to know those things that will help us take care of our responsibilties. Our education then is based on our particular response to an objective. Let us respond, and keep on getting this EDUCATION! GROUNDS AND GAMES OF TURF David C . Harmon, Manager of Recreational Facilities The Colonial Williamsburg Foundation, Williamsburg, Va. We have heard many excellent talks over the past couple of days that have provided each of us with stimulating ideas and mounds of information. Now it's time to sit back and enjoy some of the beautiful gardens of Colonial Williamsburg as well as the old colonial game of lawn bowling. < , Do you want a game for your country-club-at-home that everybody can play? One f that s easy to learn? Do you want a sport that does not need lots of elaborate equipment which costs money? Do you want a pasttime which can be played in a small space? Do you want something that's exercise yet fun for the whole family? When you bowl on the lawn you are enjoying England's oldest competitive sport, and one that is rapidly becoming popular in this country. To be sure, you needn't play it on the lawn. In Florida today it is widely played on m a r l , a mixture of clay and lime over which a sprinkling of sand has been thrown. Certainly it is one of the best of all sports for the lawn, lots of fun, and a marvelous party or family game. Incidentally, this game of bowls will not damage turf for play is seldom confined to a small area due to the variations in distance and direction which the bowls take. Nor will you find yourself obliged to shift your court about from time to time as you will in those more strenuous sports such as badminton, or volley ball, in order to save your grass from becoming a dust bowl. But if lawn bowls is somewhat less active than games like badminton, it's first class exercise nevertheless, and a first class reducing sport in the bargain. It involves constant reaching, stretching, stooping, bending and throwing. Unlike indoor bowling, which is often a game of strength where you try to knock down a set of pins with one hard, well-directed b l o w , in lawn bowls the ball is delivered gently and requires skill and science to bring to a stop just at the spot you desire. To become expert in this game requires concentrated practice, and yet there is much in it to lead the beginner to explore its fascination. Merely to bowl for fun, however, demands no special sporting skill, which is why everyone can pick it up and enjoy playing in a relatively short time. In fact, there is no age limit to its devotees. It can be played with pleasure by a boy of twelve and his grandfather of eighty. And they can both compete together. Name me another sport, save shuffleboard, in which this is possible! Many of our modern sports are for one age group or sex. Y e s , and it's a cheap sport, too. You do not require special pants or shirts or windbreakers or special clothes or a special kind of court. The bowls are the only necessary implements of play. With care these should last as long as your interest in the game. If you have rubber soled shoes you can play in any kind of costume. Cut the grass closely, roll and water your green carefully. It must be absolutely level, firm and solid. Otherwise it can be any part of the lawn which isn't devoted to some other sport. Why not introduce this year-round sport to your members this year? I 1 i j \ ; \ < At Colonial Williamsburg we have two lawn bowling greens. One is a practice green for beginners using 328 bermudagrass. The championship green is of Penncross bentgrass and measures 120 foot square. These greens are maintained in much the same way as the greens on the golf course. At least twice a year they are aerified and topdressed. Spot topdressing is done quite often in order to achieve the perfectly level surface demanded by the bowlers. For the next few minutes, let's pretend we are on vacation back in Williamsburg to visit the many beautiful gardens maintained around the restored buildings. Williamsburg, the capitol city of colonial Virginia, has been restored to its early appearances through the generosity of the late John D . Rockefeller, Jr., and members of his family. The Colonial Williamsburg Foundation, a nonprofit educational corporation was established "That the Future May Learn From the Past". The 170acre Historic Area contains more than four-score original eighteenth-century structures, 100 colorful gardens and broad greens, and many other buildings that have been reconstructed after extensive archaeological and documentary research. Just as naturally as the colonists brought with them to American their household belongings, their kitchen utensils, their tools and books, so, many of them packed away in their baggage seeds, bulbs, and even cuttingsof their favorite plants. It is to be expected that fruit trees and kitchen-garden produce would have been thought of at the outset, but ornamentals were not forgotten, and before long they,too, were growing side by side with native plants brought into cultivation in colonial gardens. If we accept the testimony of John Josselyn, who first visited America in 1638, many European flowers were mingled with native species from the very beginning of the colonial period. The architecture of the restored buildings of Williamsburg, and their interior furnishings, are as completely authentic as expert research can make them. The landscape architects have been equally faithful in their task of re-creating the gardens of the eighteenth century. The basic work of investigation involved in restoration is difficut at b e s t , and, once authentic species are known, further patient and critical appraisal is required for the selection of truly old horticultural varieties. Plants are living things, responsive to their environment and to the care they receive, so that individuals of the same species may appear confusingly different under diverse conditions. The problem is further complicated since nearly all garden plants have been selected, crossed, and "improved" since colonial times. Certain planis used ornamentally have been hybridized, either naturally or artifically, for centuries - or even for thousands of years, as in the case of the chrysanthemums. On the other h a n d , with most native species growing w i l d , variations from the form and color known to the colonists are relatively slight, so that here one can be reasonably sure that these are essentially the same as two or three hundred years ago. Surviving drawings or detailed descriptions establish some garden forms without doubt, but with others it is not possible to be absolutely certain that the present generations of "oldfashioned" plants are identical with those of colonial days. Finally, when a correct variety is known, there still remains the problem of obtaining it today. Let me now take you on a stroll through the gardens of the Governor's Palace, the most beautiful in Williamsburg. The building itself is now an exhibition building. Alexander Spotswood, the colonial governor from 1710 to 1722, devoted his personal attention to the construction of this building. It was not1 1 formally completed until about 1720, by which time it had earned the name of "Palace from the colonists who resented the additional levies required for its construction. At the Palace, as in the less pretentious gardens of Williamsburg, the formality of English design is seen. Here we find elaborate geometrical gardens, framed with clipped hedges, and accented with topiary w o r k . Standing watch over the garden are twelve yaupons, a fast growing holly native to this area. "Twelve Apostles" were often found on English estates of the period. Additional "deceits" added to the pleasure of visitors. One such is the holly m a z e , patterned after the maze at Hampton C o u r t . In a colonial town like Williamsburg - despite being a planned city it was more rural than urban - nearly every family might raise vegetables, cultivate a few fruit trees, and berry bushes, and keep domestic animals. A horse or two, a cow, and maybe some pigs and chickens would have been most common; some households could have added sheep, goats, ducks, and geese; other households perhaps a pair of oxen. Gardening activity thus fitted into the tight complex of domestic outbuildings and fenced plots typically found on the small town lot: stables, paddock, service yard, smokehouse, w e l l , kitchen, orchard, and perhaps slave quarters. These, along with the hundreds of trees that shade the homes of Williamsburg, re-create the scenic character of the colonial town. The grounds of the Governor's Palace, with their numerous outbuildings and comparatively elaborate gardens, plus a few other more-orless extensive layouts, show in formal fashion the same combination of domestic function and natural beauty. The abundance of unfamiliar plant species in the New World and the prevailing curiosity about natural history in the eighteenth century stimulated botanical interest. Men like John Custis of Williamsburg developed specimen gardnes and exchanged plant materials and information with other plantsmen. Custis wrote a London friend: "I have a pretty little garden in which I take more satisfaction than in anything in this world and have a collection of tolerable good flowers and greens from England." In many Virginia gardens native trees, shrubs, flowers, and food plants shared space with specimens from abroad, imported usually as seeds or bulbs. 1 Although many traces were found in the ground, none of Williamsburg s eighteenthcentury gardens survived intact into the twentieth; hence the designs of today's gardens have been derived largely from English precedents and from evidence relating to sites elsewhere in the southern colonies. Geometric forms, marl or brick paths linking associated buildings, and fences along property lines as required by colonial law, contribute to the setting. Archaeological evidence, maps, written descriptions, and gardening books that might have influenced the concepts of early Williamsburg assisted in the development of appropriate gardens. In the garden plantings, emphasis is placed on materials - both native and introduced - that could have been available to colonial households. The most elegant of all the private colonial homes is the Light foot House. The mansion itself has been tastefully furnished with fine antiques and equipped with modern conveniences in order to serve as an appropriate guesthouse for distinguished visitors to Williamsburg. As you can see, working for the Colonial Williamsburg Foundation is a most unusual and rewarding position. One never knows what the next phone call will bring. I would like to close by extending an invitation to all of you to come and spend a few days in this colonial town. I'm sure every member of your family will be stimulated by what has been preserved from our past. LOOK AT THAT! SERVICE AREA David C . Harmon, Manager of Recreational Facilities The Colonial Williamsburg Foundation, Williamsburg, V a . Before I begin I would like to mention that this presentation is intended to point out many different ideas one might use to help better organize his maintenance facilities rather than downgrading anyone's operation. While watching these slides one might also say, it must take an unlimited budget to do those things. Y e s , a certain amount of money is necessary, but daily organization and housekeeping don't cost a thing. What is needed in most cases is the rebirth of enthusiasm and fortitude in the superintendent. It is my intention to plant a few seeds that will sprout during the coming season and mature into a well-organized, efficient maintenance program. Top quality golf course management starts at "home" and home is your golf course maintenance area. In my travels to many different golf courses around this country, I have seen acres and acres of beautiful turf, but I have seen few maintenance areas that I would care to talk about. Yet this portion of the golf course is more important than even the first tee. Just remember, everything that is connected with golf course maintenance starts at the maintenance area. In this location is your own office, your mechanical shop, your warehouse for supplies, your employee training area, even your gasoline station. In fact, I bet you spend more time here than you do at your own home. The point I'm trying to make is, why not have this area of your responsibility on the same par as your first tee, third green or tenth fairway. Y e s , I k n o w , the golfers, swimmers, tennis players and social members don't play or visit h e r e , so why spend the money? "Old John" is doing a great job on the golf course with what he h a s , so let's forget h i m . W e l l , let me tell you right n o w , no one is going to forget this superintendent and his men while the clubhouse gets a new addition, or a new pro shop is being built, or while six new tennis courts are being constructed or maybe a new swimming pool is on the drawing board. Just remember, without your hard work and that golf course, there would most likely be no need for a golf pro, or the tennis courts, or that large non-profit clubhouse. Your golf course is the catalyst for the entire operation and your maintenance area should be the control center for the operation. B u t , can you call your golf course maintenance area a control center fit to operate a million dollar operation? Y e s , that's probably what the land and turf is worth on most golf courses. Let's pause for a few minutes and consider what some of the important things are in our ideal maintenance center. As we proceed, remember the day of governmental regulations is upon u s , as evidenced by O.S.H.A., E.P.A.'s pesticide certification program, H.E.W's increased emphasis on conservation of our environment and resources - none the least of which is w a t e r . What do all these requirements and regulations mean to the typical golf course operation? It means that a lot of things are going to change, inclduing old traditions and habits. Let us now continue with this information in m i n d . I know all of you as conscientious golf course superintendents try extremely hard to maintain a top-quality golf course year in and year out as you see h e r e . But unfortunately, some of y o u , including certified golf course superintendents, don't take as much pride in your own golf course maintenance center as you probably should. Yes, I said maintenance center; not barn, not shed, equipment storage building or some other degrading term. This important area of your responsibility should be called with pride "The Golf Course Maintenance Center". But maybe this looks so poor that b a r n , shed, or whatever, may be the proper description. Let's now examine in detail what might be done to upgrade a sagging program. First, what about your entrance? Most clubhouses have beautiful entrances and surroundings such as these and which I'm sure you probably maintain. Why not landscape your entrance road? Then check the condition of your buildings. Rem e m b e r , you never get a second chance to make a good first impression. One of the most important features of any maintenance center is the superintendent's office. The superintendent should have a clean, quiet place to sit down at the end of a long day and go over the next day's schedule, finish those reports requested by the greens chairman or just to visit with friends. The office by all means must be heated and air conditioned. The Superintendent's name should be located near the office door along with his assistants and chief mechanic. The office furniture should include a large desk, telephone, filing cabinets, typewriter for a part-time secretary or yourself, adding machine and other supplies necessary to do your job. The superintendent should see that certificates and awards won by his crew and himself are displayed in a proper location. A clean chair should be provided for any visitors. You shouldn't have to unload a dirty chair or pull up an orange crate for someone to use. The assistant superintendent should also be provided with his own office and necessary supplies. In my assistant's office, I have located our central irrigation control panels for maximum security. Just remember, sheets of paneling are not expensive and are easy to install. Try your hand this year. Fix up your office so you can be proud to invite visitors in. The storage of your equipment is very, very important. The American Association of Agricultural Engineers states in the publication "Planning Machinery Protection" that "some farm machinery dealers say that equipment without housing reaches junk value in about half the time that housed equipment does." They have observed that equipment which looks like junk usually is treated like junk. They also say that housed equipment has a 20-25% higher trade-in value, sometimes as much as 1007o higher than unhoused equipment. So let us try to get every piece of equipment inside or at least covered with a plastic or canvas tarp. Don't leave a $7,000 tractor outside in the rain and snow. Here now are just a few types of storage facilities that might be used. Shelves can be built inside to store rotary mowers, edgers, and other small equipment in limited areas. This equipment is not heavy to lift and will utilize more floor space for larger units. Why not install a key board inside your shop where all keys to equipment can be hung when not in use? This will prevent equipment from being misused by the wrong employee. In fact, try assigning specific pieces of equipment to individual employees, then watch your repair bills and down-time disappear. Everything in its place. How about that for a goal in 1977? Here rakes, shovels and miscellaneous tools are stored for easy inventory. What about fertilizer storage? All fertilizer should be stored in an area as moisture free as possible. Keep bags up off the floor by stacking on discarded pallets. If you have a large enough area for maximum storage, be sure to take advantage of the winter discounts offered by several fertilizer companies. From now on it will be the law to store all pesticides in a separate room which can be kept locked and equipped with proper ventilation. Local fire departments should be made aware of what you have in this inventory. In order to keep all that expensive equipment running day in and day out, it is imperative to hire a qualified mechanic and then provide him with a clean, heated, well-organized shop. It is most important to see that the shop is properly lighted due to the necessity of close-up engine w o r k . I believe you will get more efficient and quality work out of your mechanic if he can operate out of a well organized shop. See that maintenance manuals are kept in a numbered filing cabinet for quick references. Ever try to order parts over the telephone by describing them by looks? Be sure your parts inventory room is always locked to prevent pilferage by a dishonest crew member. Keep those shelves clean and parts in a neat order for easy inventory. If you happen to have several pieces of Toro equipment, I would strongly urge you to sign up for the Toro Red Wagon service. Even golf courses with experienced mechanics will profit from this front door service. Keeping equipment clean and properly maintained takes time but many benefits are reaped from your efforts. Equipment that is cleaned after it has been used and equipment that is painted yearly will last so much longer. Don't let your men store equipment that looks like this. Board members will be more receptive to your requests for new equipment if they know how you have been taking care of what you now have. All employees should be graded on how well they take care of the equipment that is assigned to them and this report should be included in their personnel file for review at wage increase time. The employee on my crew who gets ahead is the one who does more than is necessary - and keeps on doing it. The employee locker room is very important in keeping a happy, satisfied crew. This is certainly not going to keep a crew satisfied or an O.S.H.A. compliance officer. Don't forget to provide equal rest rooms for each sex as well as a lounge for females. This is the law! Try assigning a different employee each month to clean the locker room daily. Since labor constitutes approximately 75% of most budgets, by all means use a time clock as your 24 hour policeman. This time clock should be located in or near the locker room. W h y not buy an old refrigerator for use in the locker room for lunches? The addition of an air conditioner would certainly improve the morale of the crew. Bulletin boards, black boards and signs play an important role in my daily communications with the crew. Here is our daily assignment board with foremen's clip boards stored close b y . I also find it helpful to use a bulletin board in the office and blackboard near the locker room showing golf course organizational chart and monthly special assignments. Signs are used outside the building for many messages. Communications are a must in saving time and money during these inflationary periods. Here the general electric portable is shown. I have located such units in our clubhouse as well as on the golf course ranger's vehicle. The superintendent, his assistants and the golf course mechanic should also be equipped with radios. A base receiver such as this can be used also to receive instant weather reports from the National Weather Service. Radios can eliminate many wasted trips back and forth across the golf course. Consider a direct line from the maintenance center to the pro shop. We use such a telephone hook-up many times each d a y . If any of you take care of the club's golf cars, treat them as you would your own equipment. Make sure they are kept clean and able to complete one or more rounds of golf each d a y . The income from these golf carsf may just help buy a new tractor or maybe a greensmower for the golf course. D o n t forget to provide a work bench and locked parts cabinet for your mechanics. But be sure to keep this area separate from the golf course mechanic's shop. Storing golf cars outside as you see here will only lead to eventual mechanical problems. A covered building for storage is much better but inside storage should be your goal. At our golf course, golf cars grossed more than $140,000 during 1976. This income can be shared with the golf course operation. Safety throughout the maintenance center should be at the top of your list. No one wants to see an employee injured because of your neglect. In 1975, it was reported that 238 employees were killed while working on the job in the State of Illinois. The figure for Ohio was 144. All together 12,600 workers were killed last year while performing their jobs. Some of these could have been golf course workers. Here a red light has been installed to warn the superintendent that the gasoline pump is on. Protective guards must be installed to protect the pump. Fire extinguishers for ABC fires are located in every room in our building as well as on all major equipment. Eye wash stations must be and are provided in case of an accident involving eye injury. O.S.H.A. states, "Where the eyes or body of any person may be exposed to injurious corrosive materials, suitable facilities for quick drenching or flushing of theeyes and body shall be provided withinthe work area for immediate emergency use." Cost of small eye wash stations such as these runs around $15.00. How about considering the installation of an outside emergency shower close to the area where sprayers are filled? What are you doing about protecting your building at night from vandals? Look into the possibility of using off-duty policemen during the summer months. 1 A safety bulletin board should be located in your employees locker room with safety posters and pertinent information changed on a regular schedule. Install a safety score board outside the shop to remind crew members of their accident record. Hard hats, safety shoes, safety glasses and goggles along with other protective equipment must be provided where necessary to protect the employee. O.S.H.A. states, "Helmets for the protection of heads of workers from impact and penetration from falling and flying objects and from limited electric shock and burns must be provided and meet the requirements and specifications as 11 found in the Federal Register. Cost of most hats runs around $6.00. At our golf course we have organized an employee safety committee which meets monthly to discuss problems and solutions to our safety needs. Each person on the committee is assigned specific responsibilties with an oral report given at monthly meetings. An incentive program has been established to reward the safe w o r k e r . This is accomplished by the giving away of gifts every 120 days through a lottery system. A safety party is held at the close of each year with my boss and safety leaders in our company on hand to present awards. The amount of money spent to maintain such a program is only a fraction of the amount that could be spent if an employee were to have a serious injury while working. By all means keep your building clean and organized. What will your boss say if he comes down and finds wasteful conditions while at the same time he is reviewing your request for a new tractor? Keep brooms and dust pans handy throughout your buildings for easy access during the d a y . I believe good housekeeping practices in the maintenance building will spill over onto the golf course. Constantly reminding your crew to work safely at home and on the job will pay tremendous dividends to your organization. Post reminders on all dangerous equipment. Use all sorts of signs and stickers where possible. Many of these can be purchased from the National Safety Council at a reasonable cost. Follow O.S.H.A. regulations now before a compliance officer shows up to conduct an inspection of your facilities. A copy of the Federal Register can be obtained at no cost by all employers; therefore ignorance of the law is no excuse. O.S.H.A. is here to stay so one might as well get his ship in shape now. Every day you wait will only cost you m o r e . To summarize in a nut shell - people can be divided into three groups: those who make things happen, those who watch things happen, and those who wonder what the hell happened. I hope you fall into the first group. Y O U , YOUR EMPLOYEES AND O.S.H.A. David C . Harmon, Manager of Recreational Facilities The Colonial Williamsburg Foundation, Williamsburg, V a . Did you know that in 1975 there were 12,600 on-the-job fatalities in the United States? Did you know that some 80,000 men and women were permanently disabled at their jobs? About 25 million persons were injured badly enough to be forced off the job for at least one d a y . Over 250 million man days were lost. Over three billion dollars was paid in workman's compensation. The rate of incidence of injury and illness cases was reported that year at 10.4 per 100 fulltime workers. Statistics such as these is part of the reason the Williams-Steiger Occupational Safety and Health Act of 1970 was passed by Congress. This Act is the most all-encompassing job-safety legislation the United States has ever seen. Y e t , how many of your employees know what O.S.H.A. means? Not m a n y , I'm sure, even though this Act was passed strictly for their benefit with the cost to the employers running into the millions of dollars. Who is affected by this Act? The Act applies to every employer engaged in commerce in the United States, District of Columbia, and U . S. territories. U . S . Government employees are not covered by the Act unless the state has filed an acceptable plan with the Federal Government. Charitable or non-profit organizations are covered by the A c t , as are churches and religious institutions when they employ persons in secular activities. It was the desire of Congress to have every working man and woman covered by some safety and health act, so whether it be the Federal A c t , State A c t s , or Federal Agency regulations, every worker now or in the near future will come under safety and health standards to insure his or her safety while working. What are your obligations under this Act? First, employers are required to furnish their employees with places of employment that are free from recognized hazards that can cause death or injury. The employer must also comply with the safety and health standards issued under the Act such as record keeping, reducing hazards, informing employees, e t c . The Act also states that "each employee has the duty to comply" with O.S.H.A.'s safety and health standards as they apply to his own actions and conduct. However, the major burden rests with the employer for employee education, as well as for interpretation of what constitutes safety and health standards. The superintendent has a definite role in meeting the existing standards and in defining and avoiding hazards. Since he is in charge of a large group of employees involved in potentially hazardous jobs, the steps taken by the superintendent to protect and safeguard their personal safety and health are critically important. Any employee, who believes that a violation of job safety or health standards exists, may request an inspection from an O.S.H.A. compliance officer with the guarantee that his employer will not know his identity. The Act also provides that no employee may be discharged or discriminated against because he files a complaint or testifies in any proceedings related to the A c t . An employer may take disciplinary action against an employee who refuses to comply with safety regulations or refuses to use the safety equipment provided. However, the employer bears full responsibility for enforcing the O.S.H.A. standards. He must not only provide safe premises and post rules of conduct and safety equipment, but he must also see to it that his employees read the rules and standards, that they understand them, and that they carry them out. What about inspections? Inspections and/or investigations are performed on a priority basis and complaints by employees and/or employers rank high. First is the investigation of catastrophes and fatalities; following are complaints by employees, target industries and the random inspection of all types of industries and establishm e n t s . A Labor Department safety compliance officer may enter any establishment to inspect the premises at any reasonable time and without prior notification. The Act permits the employer and a representative of the employees to accompany the compliance officer during the inspection. When an inspection or investigation reveals a violation, the employer is issued a written citation describing the, specific nature of the violation. In 1977 it will require more than ten non-serious violations before any fine will be assessed. If a business does have more than ten non-serious violations, they will be notified of the amount of the fine, if a n y , within a reasonable time after issuance of the citations. For each violation, a fine of up to $1,000 may be imposed; for a serious violation, a mandatory fine of up to $1,000 must be imposed. An employer may be fined up to $1,000 per day for each day past the time limit in which he fails to correct a violation. An employer may be fined up to $10,000 for each willful or repetitive violation of the A c t . An employer may be fined up to $10,000 and imprisioned up to six months for a willful violation leading to the death of an employee; double the penalty for a second offense. The Act requires that employers keep accurate records and make periodic reports of work-related deaths, injuries and illnesses when medical treatment (excluding first aid) is required. Any accident fatal to one or more employees or which requires hospitalization of five or more employees must be reported to the Occupational Safety and Health Administration within 48 hours. Employers can be required to keep accurate records of employee exposures to potentially toxic materials or harmful physical agents. What are the immediate standards which must be met by the golf course superintendent? 1. That no employee dealing with toxic materials or harmful physical agents will suffer material impairment of health or functional capacity, even if such employee has regular exposure to the hazard dealt with by such standard for the period of his working life. 2 . Development and prescription of labels or other appropriate forms of warning so that employees are made aware of all hazards to which they are exposed. 3. Prescription of suitable protective equipment. 4 . Monitoring employee exposure to hazards at such locations and intervals and in such manner as may be necessary for the protection of employees. 5 . Prescription of the type and frequency of medical examinations or other tests for employees exposed to health hazards. Now let us take a look at some of the protective equipment that should be provided by you and used by your employees and also some of the safety equipment and programs you should make available to the employee. A great majority of these items can be obtained by catalog through a local safety supply company. 1. The law requires that your employees be informed of the job safety and health protection provided under the A c t . This is attained by requiring you to post 11 the "OSHA Poster in a prominent place in the establishment to which your employees usually report to w o r k . 2 . The Act requires that respirators be provided by the employer when such equipment is necessary to protect the employee. Respirators must be provided which are applicable and suitable for the intended purpose. In addition, employees must be trained in the proper use and limitations of the equipment. 3 . Where there is a reasonable chance that eye injury might occur, protective eye and face equipment must be provided under the A c t . The equipment must provide adequate protection, fit properly, be durable, be capable of being disinfected and cleaned, and be kept in good repair. It will be up to you and your supervisors to constantly check for violations among your employees. 4 . Helmets and head protective gear must be provided where necessary to protect workers from impact and penetration of falling and flying objects, and from limited electrical shock. In the State of Virginia, the O.S.H.A. Director requires approved safety hats be worn by all golf course employees while working on the course. 5 . First aid supplies, as approved by a consulting physician, must be readily available. Empty cabinets are a no-no and those found will receive a citation. 6 . Protection against noise exposure must be provided. Employers must ascertain that noise levels do not exceed O.S.H.A. standards, and if they d o , ear protection equipment must be supplied. Did you realize that the noise generated by a small leaf blower is equivalent to a pneumatic air hammer? 7. Where there is a danger of hazardous materials splashing onto the body or into the eyes, eye-wash fountains and/or emergency showers must be provided. 8 . Flammable or combustible liquids must be kept in safety cans of approved size and construction. Each can must be labeled to its proper contents and stored in approved locations. 9 . Floors must be kept clean and non-slipperty. locked or blocked. Exits must be marked, not 10. Protective clothing (including gloves, shields, safety shoes and aprons) must be provided when chemical hazards, mechanical irritants, radiological hazards or hazards of the environment or processes may cause injury through adsorption or contact. 11. Portable fire extinguishers must be kept in conspicuously located places where they will be readily accessible and immediately available in the event of a fire. On-the-job fires in 1975 amounted to losses amounting to over two billion dollars. 12. Fires are classified into four general categories as follows: Class A - fires in ordinary combustible material, such as w o o d , cloth, paper and rubber. Class B - fires in flammable liquids, gases and grease. Class C - fires which involve energized electrical equipment where the electrical non-conductivity of the extinguishing media is of importance. Class D - fires in combustible, metals,such as magnesium, titanium, sodium and potassium. In purchasing your fire extinguishers, select ones rated for Class A , B and C fires. Fire extinguishers must be installed on hangers or in brackets provided. Extinguishers not exceeding 40 pounds may be installed so that the top is no more than 5 feet above the floor. All extinguishers must be inspected on an annual basis and recharged if need be or replaced. Don't take any chances and overlook this most important part of your safety program. 13. Most golf courses have their own gasoline pumps, but many are in violation of current O.S.H.A. standards. A suitable fire extinguisher must be located within 75 feet of the pump. No smoking signs must be posted and guard posts shall be provided. All engines must be off when gas is being placed in vehicles. Citations w i l l be issued if you are not providing or following these procedures. 14. Is your maintenance building protected if a serious fire were to occur? Did you know you can have a direct fire alarm system connected to the closest fire station to you? In most areas, for as little as $5.00 per month, your maintenance building can be protected. Our complete maintenance center has such a system. Heat sensors are located in every room and connected through a master control unit to the local fire station. In the event of a fire, a signal is sent from the sensor through private telephone lines directly to the fire station. Within minutes a fire truck is on the site. The master control unit in the building also is installed with a fire bell to warn employees of danger. This system does have its own battery source in the event of a power failure. 15. Compressed air used around your shop shall not be used for cleaning purposes except where reduced to less than 30 p.s.i. and then only with effective chip guarding and personal equipment. Use an overhead recoil hose holder if possible. This will eliminate someone tripping over a hose left on the ground. Post caution signs at your air compressor. 16. Machinery such as abrasive grinders must have safety guards. When in u s e , protective equipment must be worn by employees. Machinery must be grounded if it has a m o t o r , heater or compressor. 17. Every place of employment shall be provided with adequate toilet facilities which are lockable or separate for each sex. The sewage disposal method shall comply with requirements of the health department or other authorities having jurisdiction. In all places of employment where employees are permitted to lunch on the premises, an adequate space suitable for that purpose shall be provided for the maximum number of employees who may use such space at one time. 18. Warning lights can be used very effectively on your golf course equipment to help warn the golfers of approaching maintenance equipment and w o r k e r s . Equipment can hide in the trees or below a hilltop weaving the employee subjected to a possible head or eye injury. Lights are installed on all large equipment used on our golf courses. Back-up alarms are also installed on large and noisy pieces of equipment. Roll-over protection and seat belts are required on all tractors used for agricultural, industrial and construction applications. This applies to all tractors manufactured afterl969 and over 20 h . p . Check with your local O.S.H.A. office about L.C.G tractors. 19. Signs of all kinds can be and should be used by each of you to warn employees of possible dangers, hazards or to convey your own safety program. Sometimes a picture is worth a thousand w o r d s . 20. In the event an accident does occur, fast communications are a m u s t , My crew can communicate almost instantly in the event it is required. All telephones have taped to them the phone numbers of the local security, fire and rescue units and the poison control center in the area. How about your phones? Two-way radios carried by selected employees provide instant communication while on the golf course. What would you do if you needed instant help on your golf course? 2 1 . Standards pertaining to electrical requirements have been cited as violations more frequently than any other O.S.H.A. standard. Some of the requirements are as follows: Each fuse box and/or circuit breaker must be legibly marked to indicate its purpose unless its purpose is evident. The grounding provisions of the O.S.H.A. Standards require that all dead-metal parts of electrical power driven equipment shall be grounded. Wherever wires are joined, such as at outlets, switches, junction b o x e s , they must be covered. Flexible cords may not be used where run through holes in w a l l s , ceilings, or floors. Flexible cords must be continuous lengths without splices or taps. Equipment connected by flexible cords must be grounded either by a three wire cord or by a separate ground w i r e . AND LAST, BUT NOT LEAST, IS YOUR OWN SAFETY PROGRAM. HOW IS A SUCCESSFUL PROGRAM ESTABLISHED? A successful safety program depends on three essential elements: 1. 2. Leadership by top management. Safe and healthful working conditions. 3. Safe work practices by employees. Leadership by top management cannot be delegated. The employer or chief executive must be willing to accept the responsibility to set the firm's safety policies, stimulate safety awareness in others, and show his own interest if others are to follow and cooperate. All representatives of management must reflect the same interest and attitudes. Safe and healthful operations means doing all jobs in the proper and most efficient manner. It also means keeping the work place as safe and healthful as possible. The proper way to do a job should be the safe w a y . To do his job the proper w a y , an employee must learn how to do it; and the best way for him to learn is through training and practice. Just knowing how to do a job safely is not enough. A safe operation requires constant attention and reinforcement by additional training. This can be provided by well-planned, regular safety and health meetings that motivate employees and supervisors to be safety conscious. Employers often fail to realize the value of 1a1 safety and health committee. Frequently, supervisors have been left to "find time for safety and health responsibilities along with their other "normal" activities. A committee does not take away the supervisor's responsibility; it assists him in his constant efforts to maintain an effective safety and health program. To be successful, a safety and health committee should be involved in the actual planning of the safety and health program and should have a part in making the program w o r k . An effective safety and health program means training - training for supervisors and training for employees. It also takes the vigorous support of all levels of management. The effectiveness of a safety program is usually directly proportional to the support of management. Use of safety posters and signs should be used throughout your buildings. These posters should be changed weekly and kept in good condition. Why not establish a safety bulletin board in your locker room and assign one of the employees to be responsible for keeping it up? Maybe use a safety score board to let the crew know what their safety record is. At our course we have established an employee safety committee which meets once a month. Members change yearly in hopes that each employee will get his chance to serve. At the end of each four month period, those employees with no-accident records are eligible for a blind draw in which different gifts are given away. A yearly safety party is given at the end of the year with cakes, cookies and drinks provided by management. My boss and safety leaders in our company are invited to attend and make special awards. The employee who has done the most for promoting safety on-the-job is presented with special awards and designated 'Mr. Safety' for that year. A safety plaque is displayed in a prominent location in our maintenance center at all times. All the above-mentioned things are but a small expense compared to having one of your employees seriously injured or killed while on the job. Now is the time to act. Take time to form that partnership with your employees and government. Don't wait till one of your employees is injured or an O.S.H.A. compliance officer arrives on the scene. Don't monkey around with the health and safety of your employees. This is one time where procrastination can eliminate or maim our most important natural resource - you and m e . ZOYSIA OVERVIEW Douglas T . Hawes, Turf Instructor and Researcher University of Maryland, College Park, Maryland As a New Englander, who arrived in the h o t , humid transition zone eleven years a g o , I have just recently come to a full appreciation of zoysia. I was raised on Kentucky bluegrass and colonial and creeping bentgrass with more than ample amounts of Poa annua thrown in. Zoysia was just one of those tropical grasses the Southerners grew. In my early years in Maryland, bermuda, not zoysia, was selling like hot cakes to new homeowners. Their hydroseeded bluegrass-ryegrass lawns on Maryland subsoils had failed the first summer and they were finding bermuda a cheap, rapid covering turf species. My first experience was with common bermuda in my weedy bluegrass lawn. It took a while to comprehend just how fast that weed could grow. I hand pulled a lot of bermuda out of only 800 sq. ft. before I gave up and decided to grow it instead. I still think of it as a nasty but useful w e e d . Winterkill, spring deadspot and a high nitrogen requirement make berudagrass a questionable choice for most turf areas. On athletic fields where ability to recover rapidly from intense traffic is essential, 1 bermudagrass overseeded to 'Manhattan or 'Pennfine' perennial ryegrass is an excellent choice for the transition zone. But bermudagrass is not an excellent choice for homeowner lawns, golf course fairways or like areas receiving only moderate traffic. After four or five years in Maryland, I learned that annual bluegrass truly should be considered an annual. Kentucky bluegrass would grow well only where protected from the afternoon sun. Fine fescues were fine for well drained shady areas. Creeping bentgrass survived on putting greens if you had lots of fungicides and w a t e r . Tall fescue was a coarse bladed weed which only gave decent turf if mowed three inches or higher, but zoysia survived in sun or shade, mowed or not, fertilized or not. It really wasn't until two or three years ago that I became a full-fledged zoysia fan. There was no one characteristic that converted me; just years of hopeless disgust with everything else combined with a quietly growing respect for this grass of oriental origin. Let's look at its advantages. Advantages of Zoysia for Transition Zone Zoysia, once established, requires a minimal amount of nitrogen, water and mowing. The nitrogen requirement appears to be about 1 to 2 lb.N/1000 sq.ft. This amount gives you a very nice dense turf. Only bermuda and tall fescue seem to need less water than this drought tolerant species. Mowing needs in the transition zone are highest in July and August. Although this grass is often advertized as needing only infrequent mowing, the fact is that more is needed for long term quality turf. Only heavy reel type mowers should be used for best results. japónica strains of zoysia are much more winter hardy than even the most winter hardy bermudas. They are, however, still brown from the first frost until spring. Zoysias can withstand close mowing. There is a nine hole government managed facility just north of the District of Columbia which has had Meyer zoysia greens for the past 24 years. They don't begin to compare with creeping bentgrass greens in putting quality, but the point I would like to make is they have survived for 24 years with a minimum of maintenance at a cutting height of about l/3rd of an inch. There are two things I would like you to consider here. First, that zoysia is quite capable of surviving under low mowing. Secondly, zoysia may be at its best when managed at a low level of maintenance. Time and time again I have seen zoysia persisting in quite acceptable condition where it received only minimal management. D r . Strickland, Maryland's long time turf consultant for athletic fields calls this "benevolent neglect". He claims all turf species do better with this type of management. I'm not asking you to buy that, but you will find that zoysia is capable of providing decent turf when managed with "benevolent neglect". Meyer zoysia is not a weed problem like bermuda. It will only slowly invade sand traps and flower b e d s . I have never seen it growing into shrubbery the way bermuda does. I'm told, though, that it will break up asphalt almost as fast at bermuda. Last, but not least, if you have to manage turf in or on the edge of a city, it is very tolerant of air pollution. Zoyzia's ability to tolerate heat, air pollution, and some shade make it an ideal grass for lawns in heavily populated urban areas of the transition zone. I would like to note here that in Japan zoysia is the predominant forage species in pasture as well as the dominant turf species on golf courses and lawns. To be useful, zoysia must be established vegetatively from winter hardy varieties. Horizontal stem material is extremely slow to root. Meyer, the preferred variety, is a very slow spreader. Put these three factors together and you have the basis for understanding why zoysia sod is expensive. This explains the reason for primarily establishing zoysia by plugs or sod. Research is needed to find a way to cause zoysia stolons to root faster. Mowing is difficult. Heavy reel-type mowers that are kept sharp will give best results. A complaint of bristle-like sponginess appears to be due to a combination of management practices. Excess nitrogen with or without too high mowing results in a slightly unstable footing. The long, stiff bristle-like growth isn't quite strong enough to hold one up firmly. Using a mower that is too light or mowing too infrequently will produce the same results. Close mowing or vertical thinning and sweeping in early spring (or in midsummer) can reduce thatch. Earthworms ingest much dead tissue and reduce thatch. There are billbugs and nematode problems that can't be ignored. Although the latter of the two pests doesn't seem to be a problem here in the Midwest, they definitely are causing losses in the Maryland area. The conditions under which the turf becomes susceptible to these two turf pests are not k n o w n . Both pests are difficult to diagnose, and usually have caused much damage by the time a correct diagnosis is m a d e . More research is needed on these two problems. Excess thatch favors the billbugs. The brown winter color is disliked by m a n y , but it provides a better sports turf cushion than bermuda when dormant. Zoysia is also much more difficult to overseed in the fall for winter green color. It does appear, though, that if managed to favor Kentucky bluegrass (mid-fall fertilization), a reasonably satisfactory combination turf can be managed without yearly reseeding. Such a combination turf does have the drawback of a patchy fall transition period, though. Warm-Cool Season Grass Combinations My present research is with such combinations. I have found that a bermudacreeping bentgrass combination properly managed provides one with an aggressive turf which will survive nicely under low mowing. Meyer zoysia and Kentucky bluegrass is another promising combination which I will look closely at in the years to come. 2 M y first study on combination turf used high nitrogen levels (6# N/1000 ft / season). A program of warm season nitrogen fertilization resulted in bermuda invading all combinations and in the death of the cool season grasses. Zoysia survived, but did no more than hold its own. Under a cool season nitrogen fertilization program, creeping bentgrass and Kentucky bluegrass dominated the plots in spring and early summer. Bermudagrass would dominate by the end of summer and in early fall. Zoysia still did nothing more than hold its own. Future work on zoysia will be conducted at varying N levels, emphasizing lower N rates which should favor zoysia. Summary In the transition zone zoysia is capable of handling the heat, humidity, and pollution with less tendency to be weedy than bermudagrasses. It is also more winter hardy and requires less management than bermuda. Zoysia is difficult, slow and expensive to establish. It does have pests problems, but these do not appear to be as serious as those of other turf species used in the transition zone. I think your move from bermuda to zoysia in the Southern Illinois-Indiana area is to be complimented. WARM SEASON GRASSES - THEIR ADAPTATION AND USE IN VIRGINIA J . F . Shoulders, Turf Specialist, Department of Agronomy VPI and State University, Blacksburg, Virginia There is a moderate to intense interest in warm season grasses in Virginia depending on the area of the state involved. The interest centers primarily on the adaptation and use of bermudagrass, but to a lesser extent on zoysiagrass as w e l l . The interest in Centipedegrass and S t . Augustinegrass is limited to the near sea level areas in Southeastern Virginia, due to the low level of cold tolerance exhibited by these species. Homeowners and turf m a n o r s are interested in bermudagrass and zoysiagrass because these species are better adapted for turf in the warmer areas of the state, and are easier to manage than Kentucky 31 fescue. The transition zone between warm and cool season turf species passes through Virginia and influences turf management practices in much of the state. In this zone there is great variation in climate within short distances. Extreme changes in temperature often occur within a matter of hours and the area is subject to periods of moisture stress with from short to extended periods of drought occurring during most years. The cold temperatures and weather conditions of winter often causes injury or serious loss of bermudagrass. In periods of hotter summers and mild winters the use of bermudagrass on golf courses especially tends to move northward. The introduction of varieties with more cold tolerance has resulted in the use of bermudagrass for turf especially on fairways and football fields in areas norlh and west of the traditional bermudagrass areas. The use of zoysiagrass has expanded slower than bermudagrass during the past twenty years, due largely to its slow rate of establishment from plugs or stolons and the cost involved when establishment is achieved quickly by sodding. Where adapted, bermudagrass and zoysiagrass exhibit superior tolerance to heat, drought and wear to Kentucky 31 fescue. They also will tolerate mowing heights of H a minimum of 1/2" and 3 / 4 respectively, in lawn and general turf areas, and normally are not seriously injured by disease except when conditions that cause a high level of stress are encountered. Both species are persistant but have a tendency to produce thatch which must be controlled or unsatisfactory turf or even loss of large areas of turf usually results. Much of our work at Virginia Tech has involved overseeding of bermudagrass under green and tee management with temperate species in an effort to reduce the undesirable characteristics of the transition from cool to warm season species. Other work has involved evaluation of promising varieties for use in lawns, athletic fields, fairways, and tees. The following bermudagrass varieties and strains are currently in the testing program: Variety Tifgreen Tifdwarf Tifway Tufcote Midiron Burning Tree ) Snyder ) 8 selections from ) Appalachian areas) Use or Potential Use Greens, golf or bowling Greens, golf or bowling Fairways, tees, and lawns Athletic fields, lawns, fairways and tees Same as for Tufcote Being evaluated to determine if they are better adapted than the currently used varieties Four zoysia varieties are currently in the testing program: M e y e r , Emerald, Midwest and 21-15-24. Meyer and Emerald are in general use for lawns scattered throughout the state at elevations lower than 2000 ft., generally below 1000 ft., but persists in the Blacksburg area at elevations of slightly higher than 2000 ft. Oaklawn and Tennessee Hardy Centipedegrass and one strain of St. Augustinegrass are being observed in plots in Southeastern Virginia. Common bermudagrass has been used for many years in southern and coastal plain Virginia for lawns, athletic fields, fairways and tees. Tifgreen and later Tifdwarf have gained rapid acceptance for greens in Southeastern Virginia following their introduction. In recent years, Tufcote and Midiron bermudagrass with their greater tolerance to cold are expanding the traditional bermudagrass area north and w e s t , particularly for athletic fields. D r . R . E . Schmidt at Virginia Tech is currently expanding research with bermudagrass in south central Virginia. Studies at Blacksburg will be aimed at a better understanding of cold susceptibility and tolerance and at management techniques that will enhance winter survival. Meyer and Emerald zoysiagrass are used almost entirely for lawns although some zoysia is used around tees and for other special uses on a few golf courses. One baseball infield in a city park has been sodded to this species. It has potential for fairways, formal turf areas in parks, and a much greater use for home lawns. As more cold tolerant varieties become available and cultural practices that impart a higher level of adaptability are developed we expect the use of bermudagrass and zoysiagrass to increase within the transition zone and to extend northward beyond it for specialized turf use. Satisfactory performance of these species in climatic conditions for which they are only partially adapted can be expected to require the use of well selected varieties and the skill of a highly trained turf m a n a g e r . GRASS SEED YESTERDAY. TODAY AND TOMORROW Robert J , Peterson, Vice-President E , F . Burlingham 6c Sons, Forest Grove, Oregon The high quality turf seed available today is certainly the result of what we have learned in the past. To an even greater degree, the grass seed of tomorrow will be the result of an opportunity to use techniques we have now perfected, plus the opportunity to continue our research. We can, in the future, produce even higher quality seeds, in spite of the various restrictions which will be forced upon us by environmental legislation. For a moment let us take a look back at the past. It has not been too long ago that grass seed was a by-product rather than a cultivated agricultural crop. For example, Kentucky bluegrass was stripped from old pastures in the Midwest. In the mid1920' s a group of agricultural leaders in the State of Oregon undertook a study to find a new source of income. This group recorded the following statement: "Due to its relatively high value per pound and the high yield per acre of small seeds in Oregon, it is recommended that the Oregon farmers enter more extensively into the production of small seeds such as clovers, grasses, and certain vetches." It was envisioned by these men that seeds might bring into the state an additional income of at least two million dollars annually. In 1976, the annual return is more than seven million dollars in Oregon alone, and it is still growing. The world looks to the Pacific Northwest as a source of grass seed and the place to have their new varieties increased due to high quality seeds. Today over 300 varieties are being produced in Oregon, and approximately two-thirds of these are turfgrass varieties. Once again, if we look back for a moment at Kentucky bluegrass, Merion was released in 1947, Park in 1957, and Newport in 1958 - not long ago. In the last eight or ten years the number of new cultivars released by both domestic and foreign breeders has increased very rapidly. For instance, our company is producing seed from 61 separate cultivars. Seed growers who became skilled professionals in the business of growing seed are now moving into second and third generations of persons. Specialization in the production of seeds has been accompanied by the improvising and remodeling of the special equipment needed to perform the necessary functions of seed production. With that brief background we now come to the subject of grass seed today. specifics in the production of high quality turfgrass seed involve three major The concerns - genetic purity, mechanical purity, and high germination. Genetic purity is critical to insure that the user obtains seed that is true to the variety selected. Mechanical purity insures the user that the seed he obtains is free of unwanted weed seeds, and contaminating crop seed. The highest germination possible for each specific variety is necessary for early establishment. The remarkable array of new cultivars improve the quality of turf due to their improved disease resistance, texture, color, vigor, longer growing season, and ability to withstand close mowing. To visit these plant breeders across the United States, as well as other parts of the world is indeed a time consuming process, but I know of no other way to keep current on the materials these people are working w i t h . One of the rewards of this type of effort has been the interesting and enjoyable cooperation between the researchers of the land grant universities and the seed industry. Turf trials on performance over a wide area are necessary to confirm the merits of these new cultivars. Meanwhile, the potential seed yield must be proven. Some of these new strong turf type grasses are poor seed yielders and some may show rather poor germination. As a matter of fact, some experimentáis may produce good turf, but have to be dropped because they are such poor seed producers. The programs that are involved in production of genetically pure seed may not at first glance seem difficult until you realize that annually we produce in Oregon on approximately 300,000 acres over 250,000,000 pounds of seed. The requirements of certification of this seed embody certain ground rules that must be adhered to. Land history requirements state that any new seeding of a specific variety must be on land that has not grown another variety of the same species in the preceding three to five years, depending on the species involved. In addition, isolation must be maintained between varieties of the same species, 165 feet in the case of ryegrasses, bentgrasses, and fine fescues, and 1 rod or 16-1/2 feet in the case of bluegrasses. These isolation distances must be maintained throughout the life of the stand. The land history and isolation becomes no small task when you realize the over 300 varieties of certified seed being produced in Oregon. All of our production, whether it be our own proprietary varieties or those of others, are produced under contract and under our own supervision. We employ trained agronomists to work with the grower in selecting fields that are qualified for the particular cultural practices involved. We have a dozen or more selective herbicides that can be used to help accomplish this task, but precision is a k e y . To be almost right simply will not be good enough. Two techniques that have developed in the past seven or eight years are designed to help establish seedling grasses that are essentially weed free. These are widely used, and are called chemical seed bed preparation and charcoaled seeding. In the case of chemical seed b e d , a grower prepared his field for planting in the fall, but rather than seeding he allowed the ground to lay fallow, the weeds and contaminates are allowed to germinate and are then sprayed with a herbicide for grassy and broadleaf weed control. The crop is then planted in the spring without additional tilling. Most of the troublesome weeds germinate during the fall and winter and are eliminated. In addition, if necessary, a herbicide such as paraquat is applied just after seeding but before emergence of the crop. The charcoal seeding allows a further dimension. Since all our seed crops are planted in rows up to 16" w i d e , a narrow band of activiated charcoal can be sprayed over the crop row at the time of planting and then the field given a broadcast application of a sterilant herbicide. This can all be done in one operation, with seeder, charcoal application and sprayer mounted in tandem. The charcoal over the row absorbs the herbicide, deactivates it, thus protecting the germinating plants. We have not done away completely with the necessary use of spot sprayers, or in some cases hand roguing, but we have reduced these operations to a minium. A specific herbicide program is used each fall for control of grassy weed or volunteer plants from shattered seeds. We have indeed come a long w a y . The consumer has a perfect right to ask for the highest quality seed he is willing to pay for, but seed is an agricultural product and despite all best efforts it is obvious that not all can meet the highest standards. As an example, when you ask for Kentucky bluegrass which is crop and weed free in a 25 gram sample, that is approximately 100,000 individual seeds without one contaminate. Harvest of our seed crops starts in late June as the ripe seed matures. Crops are windrowed and allowed to remain in these windrows one week until the moisture content of the seed is in the range of 8 to 10 percent. Seed is combined directly from the windrows using a pick-up attachment. From the combine seed is emptied into boxes which can be clearly labeled and are used for storage until seed is ready to be milled in the cleaning plant. Despite the work and effort that goes into the production of high quality seed in the field, the job is only partially done. The equipment used for harvest must be thoroughly cleaned between each use to avoid contamination and attention to housekeeping in the cleaning plant is essential. The equipment used in the mills must be cleaned between lots of seed as well as a good system of checks as the boxes are being dumped. A n y mistake here can indeed destroy an entire lot of certified seed. As a background for the history of field burning, let me say that the straw residue, unless removed, retards plant growth, reduces seed yield, as well as providing a medium for disease transmission from one year to the next. The most notable disease being blindseed disease which destroys germination of the seed. The dry summers that favor seed maturation also produce d r y , highly combustible straw necessary for an effective burning. A plowed strip four to eight feet wide around each field is maintained as a fire break and cultivated periodically to control vegetative growth. Fire is lighted on the downwind side of the field and allowed to burn against the wind as a back fire, When the back fire has burned a safe distance the perimeter of the field is ignited. Once the field is encircled in fire, the rising heat creates a draft which draws the fire together from all sides, completing the operation in a matter of minutes. The hazard involved in this operation, other than the smoke which has caused much controversy, is wind shifts which can transform the back fire into a main burn. Permits are required in order to burn, and these permits control the number of acres burned in any one area and are available only when smoke dispersal is good and wind direction is satisfactory in relation to a given field and its surroundings. Objection to this practice came with the increase in population in the valley and especially the south end which is surrounded by hills and can, under certain conditions, act as a trap for the smoke. Research into a mobile field sanitizer has been in progress for a number of years, along with companion projects to find markets for this one million tons of straw which would have to be removed in order to use the field burner. A million tons of straw, when baled in 40 pound bales, will make a stack approximately 15 feet high, 30 feet w i d e , and over 100 miles long, and in order to be used it must be preserved in some method for once that fall rain starts, the straw will deteriorate. This obviously means some form of densification and storage if this material is to be used. With the advent of the fall rain these perennial grass fields begin their regrowth and the cycle is repeated. BUILDING A MACHINE - A CHALLENGE H . F . Carroll, Foxcroft Meadows, Crystal Lake, Illinois Every development of a machine must have some motivation. 11 was the old proverb, "Necessity is the mother of invent ion . In our case, it "We are operators of a 600 acre sod farm near Crystal Lake, Illinois, which is about fifty miles northwest of Chicago. We started using pallets in our sod business in 1953. Although plenty of forklifts, built around standard farm tractors were avilable for loading in the field, the unloading and spotting at the delivery site was a real problem. A standard forklift is heavy, quite difficult to transport, a little hard to maneuver in close quarters, and costly. We needed a machine for unloading that was: 1. lighter in weight; 2. easier transported; 3 . more maneuverable; 4 . easier serviced; 5 . lower in cost. In 1956 we made an attempt to build an unloading machine around a Gravely tractor. It was slow and would not work on pallets that were directly over the drive wheels of the truck. The idea was abandoned. About that time we contracted our trucking to a group of hard working farm boys who did not mind slinging the sod off the pallets to the ground. We received a lot of complaints on broken sod, and we could not get the sod spotted on the site. At least the pressure was taken off for an immediate1 need of an 1 unloading machine. As our truckers grew older and a little less gung-ho on the physical slinging of sod, we again revived the idea of a need for a mechanical unloader. We visited some of the professional forklift manufacturers during 1971. We told them of our need for a light weight device that could be carried on our trucks without sacrificing too much payload. We wanted the device to handle at least 3,000 pounds. The typical conversation always ended like this: (Forklift people) (Our answer) "How many do you want?" "Three, but other sod growers must have the same problem, and other industries have trucks to unload too." (Forklift people) f "We d o n t have a demand for such a device and we couldn't possibly build just three." After three such interviews we gave up on finding anyone to make a machine for us. We decided to try the job ourselves. We reasoned that if a spider can carry twenty times its own weight, we should be able to build a machine that need not weigh 9,000 pounds to carry 3,000 pounds. In early 1972 the idea of a hinged, oversized, motorized hand truck hit u s . Not being engineers, we started building, not drawing. First a crude wooden model to prove the principles. Then a full sized tubular framed model with small bicycle wheels to prove our hinge point locations and our center of gravity calculations. 1 1 In about two months our sod farm manager and my jack-of-all-trades son-in-law built a workable machine in our farm shop. It was crude but it worked. It went into use in the fall of 1972, and is still running. All during 1973 and 1974 we worked literally day and night testing, reading cata1 logs, interviewing salesmen and all the other things necessary to get 'off-the-shelf component parts that would best fucntion in combination with each other. All these new parts were incorporated in the original machine to simplify and improve. In the winter of 1975 we built a second machine incorporating all the changes we had made in the first one, without changing any of our original basic ideas. We took this machine to the American Sod Growers meeting in Kansas City during the summer of 1975 for their reaction. We took orders for twelve to be delivered in March of 1976 and built them in our farm shop. We wanted to get a public reaction before going any further. By the time we got some favorable reports in April, the tire industry went on strike. From a small carry-over of tires and by shipping some machines barefoot, we managed to build another thirty machines during 1976. We have orders awaiting that will carry us into May of this year. Assembling is now being done in a new 52 x 100 steel building. We are very appreciative of the encouragement received from our friends in the sod industry. Our own use experiences and repeat orders tell us we have made progress, even though I'm sure we and other people will build even better unloaders in the future. I hope this story will inspire lots of people, especially the younger ones, that there are lots of opportunities for exploiting new ideas to solve problems in America. The encouraging note is that these ideas can come from little people. W e can use the big corporations like Goodyear, T R W , Kohler, etc., by assembling 1 their precision built, mass produced, 'off-the-shelf products in combinations that will solve our problems. All we have to do is to have the idea and select the right combination of components. (Two short amateur films were run to show transporting and sod handling capabilities). M Y CREW BUILT PURR-WICKS Jack Keidel, Supt., Country Club of Terre Haute Terre Haute, Indiana Terre Haute Country Club is located in times permits year round play. Our summers humidity. With the comination of our heavy annua, our greens become a case of dynamite the Wabash Valley. Our weather someusually have high temperatures and soils and high population of Poa during the months of July and August. In the past years, continuous problems prevailed with four to five greens. After several years of facing the same problems, my greens chairman and I drew up a plan for rebuilding five new greens. All costs were figured, whether our crew or a construction company would do the w o r k . After much deliberation we decided that an additional crew and I would undertake the building of the five greens. We decided to rebuild the N o . 1 and N o . 10, the two worst greens, the first year, one the following year, and two more greens after that. N o . 10 green is situated in a sunken gully, surrounded by trees, and therefore, has very little air movement. We felt that if we could keep excessive moisture off the surface we could maintain grass throughout the year. The decision was made to use Purr-Wick and its water conservation action. The elevated tee permitted a flat green on this par 3 hole. There was only one small access to the green. After much hand labor and digging with a backhoe, we developed a Purr-Wick b a s e . Our plastic liner was taped and then laid. Then 2" slitted pipe was laid in a circular design under the green. We installed our flange and box near the rear of the green. After this installation we pretested our liner and flange and found it held water consistently. Sand samples were sent to Purdue, tested, and approved. Approximately 14" of this sand was distributed throughout the green. With only one way to get on the green, much hand work was required. As the sand was leveled by a sand pro, we watered continuously on the sand to help its settling. We added 2" of peat to the surface sand and rototilled it five or six different directions. Again we came back with the sand pro and leveled, following our watering. We applied 50# Milorganite, 8# starter fertilizer and 2# Pencross seed per 1000 f t . A f t e r seeding, a hand roller was used and a small layer of straw was applied. After ten days the straw was taken off and the green was first mowed on the 20th d a y . The following May we opened the green for play. Our membership is very happy with the condition of the green and its playability. During our extremely dry summer last year no problems were evident. We feel our crew did a fine job with the problems we were faced w i t h , and we are more than satisfied with our Purr-Wick green. WATER IN THE SOIL W . W . M c F e e , Department of Agronomy, Purdue University West Lafayette, Indiana Turf managers spend a lot of with the dual problems of keeping proper soil resilience and at the prevent the accumulation of water time and effort in managing water. They are faced enough in the soil for vigorous grass growth and same time trying to maintain conditions that will to the point that it interferes with the turf use. First, let's consider saturated flow. When the large pores in the soil are filled with w a t e r , the soil is saturated or near saturation, the water will move in response to the pull of gravity. We refer to this movement as gravitational flow or saturated flow. Under these conditions the water behaves much the same as water in plumbing. It is flow under pressure. The soil conditions that we are talking about are wet soils, not d a m p , but thoroughly w e t . Since the primary moving force in saturated flow is gravity, the less obstacle we put in the way the faster and more easily it will flow. The larger the soil pores, the faster the flow. Of course, large soil pores are usually associated with coarse textures, sands or gravel, and with well aggregated, strong structures. In a typical soil profile when we get excess water or saturated flow, it moves readily as long as there are large pores but begins to be restricted when it encounters a layer which has fine pores. The speed of removal of excess water is thus limited by the finest layer in the flow path. If, for example, we have a tile drain at a depth of three feet and a sandy loam soil over that tile except for two inches of silty clay loam somewhere in the profile, the speed with which water will reach the tile will be determined by how fast water moves through the two inches of fine material. Or let's take another example. We have a medium textured material, a natural soil which we want to drain to get rid of excess water rapidly. We install tile and backfill over the tile with sand and gravel in order to give a coarse pore system for rapid water flow. However, the top two inches is replaced with the same soil material as before to grow the grass, and we find that the rate at which excess water gets to the tile line is limited or determined by that top two inches of soil. A more desirable arrangement would be to have the sand and gravel come all the way to the surface to give direct access to the tile line through a coarse pore system. Consider Figure 1 where we have four soil profiles illustrated. We have illustrated the speed with which water will move out of these. In the first case, we have a uniform loamy sand all the way through and water moves through that rather readily. In the second case, we have a thin layer of finer texturedmaterial somewhere in that profile. This behaves as an effective barrier to rapid removal of excess water. In the third case, we have a layer of coarse material midway down the profile. Its effect on the removal of excess water will be essentially nil and the flow rate through it will be the same as it would have been through a uniform loamy sand. The fourth case, however, we have a fine textured material which is very resistant to flow and we have a tile line buried in it but over that tile line we put coarse material and brought that coarse material all the way to the surface. We take care to see that it does not get covered over with fine material through topdressing or grown over with a dense sod. There the tile will be effective in removal of excess water because we have a coarse pore system directly to that tile line. Now there is another type of flow that we call unsaturated flow. The forces involved here are the attractive forces of soil for w a t e r . The water is pulled into the soil. In this case, the finer the pore the stronger the attraction. But as the pores become very fine the speed of movement is reduced. Thus, in anything finer than a fine silt or silt loam we no longer get effective movement of water to plants by unsaturated flow. W e are all very familiar with a type of unsaturated flow that we call capillary action. This is what happens when you set a sponge down in a puddle of w a t e r . The water moves rapidly up into the sponge by capillary flow. This is a form of unsaturated flow. The same type of flow occurs in the soil when we water a green from underneath by maintaining a water table 8 to 15 inches below the rootzone allowing the water to move up by unsaturated flow or capillary action to the roots. Now the effect of coarse layers on this type of flow is quite different. A coarse pore system effectively interrupts unsaturated flow because the coarse pores have a very weak attraction for w a t e r . They will not attract the water out of the finer pore system. T h u s , as a soil material drains and all the excess water leaves, a coarse pore system will not retain much w a t e r . If you have finer zones over it, they may retain more water than they would have otherwise because the coarse zone is not exerting an attraction for the w a t e r . By analogy , a blotter full of water allowed to drip until it stopped dripping would contain more water than it would if you put another blotter or paper towel or something underneath to attract the w a t e r . If you brought another blotter in contact with the wet one, it would pull some of the water out of it. Thus, a fine layer or a layer of the same texture underneath a soil layer will attract more water from it than will a coarse one. So one legitimate use of a coarse layer is to cause a finer layer above it to store more water than it would have otherwise. Unsaturated flow or capillary action can move water in any direction. We f normally think of it as moving water upward, but i t s just as effective in moving it laterally or downward. A good example of this is the syphon effect that is sometimes encountered in a construction such as the Purr-Wick green system. In Figure 2 you see this illustrated. The water over the water table is attracted upward by the sand such that it is brought into the root zone, but at the same time it's attracted upward and laterally over the barrier into the next zone. Since the adjoining zone has a lower water table, the attraction there will be greater since it's under more tension. So we get a transfer of water from the upper pool to the adjacent pool and finally to the next one which is even lower. So we encounter a continual transfer of water from the higher levels to the lower ones. This complicates the maintenance of constant and adequate water levels under these systems. This can be overcome by elevating the barrier between the two compartments higher than the capillary rise. When this is done it establishes the height of the barrier just below the surface. This is necessary as you need a capillary rise near the surface in order to supply the root systems with adequate w a t e r . Summary Coarse layers aid in the movement of excess water only if in contact with free water at the surface. Saturated flow is limited by the finest layer in the flow path. Coarse layers cause layers above to retain a little more water when drainage ceases. Capillary flow, or unsaturated flow, working with gravity can move water over a barrier and downslope. Water moves in response to gravity (downward) and in response to soil attractive forces (all directions). Figure 1.

Holt, /s* \ WATER IN THE PLANT Department of Agronomy, Purdue University West Lafayette, Indiana Water is a principal constituent of living things and makes up more than half of the dry weight of actively metabolizing plant tissue. For example, inner lettuce leaves are about 9 5 % w a t e r , plant roots about 8 5 7 o , and grass leaves range from 7 0 - 8 0 % moisture. Dormant seeds, on the other hand, contain only 5-15% water. Water has several functions in the plant. It serves as a solvent for dissolved substances, such as salts or sugars, as a temperature regulator through the cooling effect of evaporation, and as a medium for diffusion or mass flow of materials from one part of the plant to another. Water has several important physical properties that affect its role in living tissues. Both its freezing and boiling points are high relative to other similar chemical compounds. The fact that it is a liquid between 0 and 100 C dictates that active plant metabolism can only occur with this temperature range and actually only occurs from about 10-45 C . The property of water known as capillarity, that is, the ability of water to rise in small tubes because of the attraction of water for the walls of these tubes, helps move water up the plant to the leaves. The strong forces of mutual attraction between molecules of water cause it to have a high tensile strength, so that long columns of water can be supported in plants. The small molecules of w a t e r , which move readily through plant membrances that larger organic molecules cannot traverse, and the tendency of water to move from areas of high to areas of low concentration lead to the all-important phenomenon of osmosis. Osmotic forces, coupled with evaporation of water from leaves provide the energy which moves the water up the plant. Tiny holes, which can open and close, in the leaf epidermis, provide a variable resistance to this water flow. The opening and closing of these tiny holes, called stomata, are controlled by physiological processes in the plant. Because of the various physical properties of water and the physical and chemical nature of the plant, water pressure gradients are established, especially in daylight hours, which cause water to be taken up by the roots, moved up the plant, and evaporated from the leaves. Such pressures are usually expressed in units of water potential. Water potential is always negative under natural conditions. For example: on a typical w a r m , dry summer d a y , the soil water potential is probably -0.3 atmospheres if the soil is well watered, the root about -6, stem about -10, the leaf about -12, and the atmosphere about -900. Water tends to move 11 toward "lower" water potential (-12 is "lower than -6). Because of the big difference between atmospheric and leaf water potential, water would at times be lost from the leaves too rapidly if it were not for the stomata, which can close and slow down this rapid water loss. This happens under water stress in most plants. Leaves with water potential lower than -18 bars are stressed and the stomata are closed. Of course, when stomata are closed, water cannot escape but neither can C0~ enter the plant, so photosynthesis is inhibited. This is one of the ways water stress slows growth. It is the pressure of water inside plant cells which causes them to enlarge, that is, grow. T h u s , when water is in short supply, these cell pressures do not get as high and the cells expand less. This is another way water stress limits growth. Actually cell expansion is affected more by water stress than photosynthesis, so a water stressed plant is usually denser and heavier per inch than a well watered plant. What does #11 this have to do with watering turf? The significant practical thing researchers have learned from studying the basic scientific aspects of water in plants is that plants can adapt to some extent to water stress. A plant which has been growing for a week or more under mild stress can carry on photosynthesis and expansion at lower water potentials than a well watered plant. Thus, the adapted plant makes more efficient use of its limited water supply. Also, the stress-adapted plant is much more likely to survive a period of severe drought. Surprisingly, a drought-adapted plant is more likely to survive a period of severe cold, also, because the physiological processes of drought-hardening and cold-hardening are very similar. The moral to the story is that withholding water early in the season so as to cause a mild stress will produce plants which are more likely to survive and make efficient use of a limited supply of water later in the season. Besides, excessively watered turf is more susceptible to disease. In this time of increasing concern about water shortages and the liklihood of water rationing in many areas, with non-essential uses such as watering turf getting low priority, concern about efficient water use by plants is justified. ADDITIVES AND WATER David P . Martin, Department of Agronomy, The Ohio State University Columbus, Ohio A discussion of additives and water could probably cover everything from nutrients to pesticides to surfactants. This paper will be limited to (1) some general comments on wetting agents, (2) the use of wetting agents in treating localized dry spots, (3) and a brief review of some recent work at Ohio State on the cause of localized dry spots. The effects of wetting agents have been studies for a long time. Many suggested uses and benefits of wetting agents may be found in the literature as follows: - Increased infiltration and percolation of water More uniformly wet soil profile Decreased bulk density of compacted soil Reduced localized dry spot problems Increased rooting Increased drainage Reduced soil moisture tension and increased moisture availability Reduced evaporation and water loss from soil Reduced incidence of disease Improved control of diseases Improved control of weeds Increased utilization of fertilizer nutrients Reduced wilting Perhaps the list could be even longer. documented while many have not been proven. Some of the above have been rather well Wetting agents have been marketed for turf primarily to increase water infiltration into the soil and to more uniformly wet a soil profile. What effects do wetting agents have on the properties of water to possibly account for this result? A contact angle is formed between a liquid and a solid whenever the two come into contact. The properties of the solution and solid will determine the degree or angle of that contact point. Water spreads on a hydrophilic (water-receiving) surface such as glass, forming a small contact angle. However, on a hydrophobic (water-resistant) surface such as w a x , a drop of water will "ball-up", creating a large contact angle. When a wetting agent is added to water in contact with a hydrophobic surface the solution should have a lower contact angle and wet more of the surface. Theoretically there will be much less benefit on a non-hydrophobic surface since the contact angle is low and the liquid already spread out. The effectiveness of wetting agents in actual usage will likely depend on the soil conditions and what the user is attempting to accomplish. Localized dry spots are one situation where wetting agents have had positive effects. Localized dry spots developed on several experimental sand greens at the Ohio State University turfgrass research plots. Water easily infiltrates most sand, of course, but in the case of localized dry spots it does not. Water droplets actually "ball-up" on the sand and do not soak in readily. The sand is hydrophobic. The effects of several wetting agents at different rates with and without soil coring have been studied (2). Soil coring was more effective in reducing the dry spots problems than was a wetting agent (Table 1). Wetting agents were more effective as the rates were increased to a certain point, beyond which there was no improvement. The combination of coring and wetting agent produced a greater response in turf quality and reduced dry spots than either treatment alone. Recently the nature of the hydrophobic condition has also been given careful scrutiny (1, 2). A coating surrounding individual sand particles from localized dry spots was observed through use of the electron microscope. The nature of the coating was determined to be organic by ashing and acidic through use of solubility tests. Using sophisticated analysis techniques the coating was identified as a fulvic acid-like material similar to humic acid materials resulting from organic matter decomposition. Formation of Ca and Mg fulvate may occur and on drying it may become very hydrophobic, resulting in a localized dry condition. The authors speculate that the coatings may arise from activities of various basidiomycetes. In conclusion, a number of management tools may be used to reduce the localized dry spot problem. It is important that hydrophobic soils not be allowed to dry completely prior to irrigation since the soil becomes increasingly waterrepellent as it becomes drier. It may also be desirable to pre-wet a hydrophobic soil prior to heavy irrigation in an attempt to improve water infiltration. Soil cultivation, specifically coring, is essential to reduce dry spot problems. Even coring in mid to late spring may reduce dry spot problems during the summer months. And finally, the combination of coring plus the use of a wetting agent has been the most successful practice to date to decrease the severity of localized dry spots. References: 1. Miller, R .

W y a t t , Dixie Irrigation C o . Louisville, Kentucky We will attempt, through slides and conversation, to show some of the various methods of getting that water into the pipes, and also controlled methods for removal of this water so that the most efficient use of it can be made and the most pleasure obtained from its use. To get the water into the pipes and accomplish our objective several steps of investigation are called for. Water source, elevation, water requirement, and last, but not least, a working drawing or layout, showing pipe locations, sizes, e t c . Several pieces of equipment and techniques are needed to install the pipe. Polyethelene is most flexible and lends itself to a method referred to as pulling p i p e . This method causes less disturbance to the turf, and where soil conditions are suitable it is a very good way of installing the pipe. A l s o , 1 this pipe seems to be less damaged due to freezing. Maybe from the 'Winter of 77 we will learn new things about buried pipe. The white and blue pipe is called PVC and termed rigid pipe; however, it too has some flexibility. There are various fittings available to the pipe installer. Electric controllers are used which program your water in the pipes so that it will be used most efficiently. Another method is to use a mechanical valve you merely turn off and o n . There are various sprinklers available to distribute that water in the pipe in the manner you w a n t . The large heads are capable of wetting an area from 80 to 1 over 200 in diamater 1 with from 4 to 50 G P M . Spray heads are capable of wetting an area of from 15 to 60 diameter and delivering from 2 to 7 G P M . Pumping plants may be pre-fabricated. One such example consists of two straight centrifugal pumps, pressure tank, electric controller and valves with an 800 GPM capacity. One method of joining the lengths of rigid PVC pipe together includes a coupler, known as a gasket coupler, which merely slides over the end of the pipe. This method makes each joint an expansion joint and is used extensively in pipe 2-1/2" and larger. The other method of joining this PVC pipe is with glue. To utilize water in the pipes and to distribute it properly, a swing riser is used which gives a flexible connection between the sprinkler and pipe. This decreases the chance for damage by heavy equipment moving over the sprinkler and also allows for repositioning of the sprinkler should it become necessary. Risers are made of either galvanized pipe or plastic. Redesign or repair of the pumping plant may be necessary. One such installation was experiencing high pressures that kept the superintendent busy repairing cracked pipe. A control valve built especially for this purpose was installed along with other minor changes. Sometimes a new pump installed along side an older one is practical - possibly! where the superintendent added another nine holes. Naturally one pump just w o u l d n t put enough water in the pipes for the eighteen hole course. A l s o , a turbine pump installed in a wet well can serve as a source of w a t e r . As we have seen, there are many ways of getting water in the pipes. One familiar to all is the water tower which is an accepted method of putting water in the pipes 1 for most cities needs. Proper backfilling of the pipe so that it will better contain the water is essential. Loose soil may be watered in. Other methods would be mechanical tamping, etc. We feel the method of blowing out the pipe with air pressure is far the most positive method for winter preparation, and the least disturbing. Certainly shut down and start up can be accomplished with minimum effort using this air purge. Another method used extensively some few years ago is drain valves located strategically through the area, but this is a time consuming chore and we recommend air, and if desired, a couple of drain valves. OVERVIEW OF TURF IRRIGATION Carl H . Schwartzkopf, Mid-Continent Director, USGA Green Section Crystal L a k e , Illinois Water has become a critical, invaluable resource in the United States. Currently, many areas of the country which previously had an ample water supply are experiencing a shortage. Regulations and restrictions by Federal and State agencies are being developed and implemented which will affect our lives in the future. During the drought period that is currently existing in the Pacific Northwest, California, the Rocky Mountain states, the Dakotas and many midwest areas, it is becoming apparent that we cannot take water for granted. f In the mid 1 9 6 0 s , the eastern part of the United States suffered a drought period. During this period, to conserve water supplies, golf courses were among the first to be affected by governmental authorities. Some golf courses were restricted to minimal amounts of water for irrigation, whereas others were entirely cut off from traditional sources of supply. Instances occurred where wells and pumping stations were seized under the right of eminent domain, with financial compensation paid to the courses. The action of many governmental agencies was harsh, unduly harsh, in many cases. If we are to profit from past experiences, we must study the lessons learned and give full consideration when planning and developing irrigation programs in the future. If golf courses are to have access to water they need for their survival, they must recognize their responsibilities and obligations to practice the conservation of this precious natural resource. In many areas of the country it is necessary to secure the approval of state water controls agencies before sufficient quantities of well water may be used on a golf course. Today we have an opportunity to exercise control of our spiraling irrigation costs, as well as to fulfill our responsibilities for water conservation. Therefore, when considering a new irrigation system, several factors must be taken into consideration: should the system be automatic, semi-automatic or quick coupling? With the recent labor problems that have been prevalent on golf courses, the trend has been toward an automatic irrigation system. An automatic system, if properly used, can also conserve w a t e r . There are other questions that must be considered before making a decision about an irrigation system. These include: What is the length of your irrigation season? How much water will be needed for each area? What is the availability of labor, the number of golfers, and the time available for irrigation each day? Will the water supply be adequate? The golfer, the person we should keep happy, must be given primary consideration. If your present watering schedule delays starting times, and if you must irrigate frequently throughout the d a y , causing inconvenience to the golfer, you should seriously consider automation. If labor is not available for night watering, automation is essential. Unionization is steadily making its way into golf course maintenance; therefore, every superintendent should check closely the restrictions and added costs it places upon his budget. It is important to select the correct equipment for your installation. Hydraulic or electric valves, cam, gear or impact heads and the type of controller set-up are a few of the decisions that must be m a d e . The terrain, water supply, soil, and climatic conditions should be taken into consideration when deciding on a hydraulic system versus an electric one. Purity and water quality will have an effect on the lasting quality of the sprinkler head. Suppliers of equipment should be selected carefully, not only to insure prompt delivery on initial equipment, but for future service and repairs as w e l l . Once a decision has been made as to the type of system, the greatest task still lies ahead. This is hiring and controlling the installation contractor. The very best design and the very best equipment are of little value unless they are properly installed. Many golf courses are experiencing continual irrigation problems because, when the system was installed, the quality of workmanship by an inexperienced crew was poor. Some very successful systems have been installed by golf course maintenance crews, but this should not be undertaken unless you have qualified h e l p , as well as experience in irrigation systems. Very exact specifications must be drawn up for a contractor and he should be notified as to the inspection procedure. The superintendent, or the designated quality control inspector, should have the authority to stop the installation at any time if the specifications are not being followed closely or if changes must be made in the field. No pipes should be laid until dpeth of ditches is checked; no wiring or tubing laid until the pipe is bedded in; no ditches backfilled until the blueprints are checked making sure all fittings, wires and valves are correctly placed; and no sod laid back until the fill is compacted to avoid settling. Every pipe must be checked for cleanliness, no foreign matter should be allowed in the inside to lodge in the sprinkler screens or valve parts. During installation, you, as a superintendent, or your designated inspector, should devote full time to make certain that no corners have been cut by the contractor. The success of the system definitely depends upon exactness of installation and quality of workmanship. Shortly after 11 the installation has been completed, an "as built or "as installed" blueprint should be received by the club. Putting the system into operation is simple if wiring and tubing has been connected properly, if the stations at the controller are marked correctly, and all the foregoing items have been completed. It is now that you will really appreciate the research that was completed at the outset of the irrigation project. It is now that your decisions on the type of system, the make and type of equipment, the method of installation and the careful inspection program will pay off. If these items have received your first and foremost attention, you'll have made a substantial and long-lasting contribution to the golf course. However, if the decision was reached hastily with little information gathered, and installed on the basis of the lowest bid submitted, the golfer can expect irrigation inconveniences a n d , even more important, y o u , the superintendent, would be expected to correct many of the defic iencies both in the original design, as well as in the installation. INFRARED STUDY John L . Morris, CGCS, Highland Golf and Country Club Indianapolis, Indiana I first became interested in infrared photography after seeing some of the work the USDA and the Forest Service were doing with N A S A . I am sure that you have heard of infrared, but maybe you do not quite understand what it is. William Wildman and Jack Clark have an excellent article in the October 1974 issue of Weeds Trees and T u r f . In short, they explain infrared principles as follows: The energy or light spectrum consists of cosmic rays, gamma rays, X - r a y s , ultraviolet radiation, visible light, microwaves, and radio w a v e s . Infrared is a very large segment of the energy spectrum. One part of the infrared band is 11 known as the "thermal infrared and is the result of heat being emitted from an object. Infrared color films do not record thermal infrared radiation, but record the "near infrared" radiation which is reflected from an object. Ordinary color film is sensitive to the complete visible spectrum of light. It contains all three basic layers of film that are sensitive to blue, green, and red light. During processing, the dyes form in these layers and produce a true color image. Infrared film uses only part of the visible light spectrum and is also sensitive to the near infrared portions of the spectrum. During processing, the film is developed with the same dyes that are used on ordinary color film but different wavelengths are used to process the film. Thus, false color results green is red, red is yellow, and blue is b l u e . In addition to green light, green plants reflect large amounts of near infrared radiation. The sun produces visible and infrared light that falls upon a green leaf. Chlorophyll in the leaf absorbs most of the blue and red wavelengths that provide the energy for photosynthesis. But the green light is partially reflected in greater amounts than visible green light. Any problems within the plant tissue will decrease the amount of infrared reflected, but will not reduce the amount of visible green light reflected. My first infrared pictures were taken from ground level on March 23, 1975, with a 35 m m . camera. Since growth was just starting, photosynthesis was at various levels on different species of grasses. Therefore, chlorophyll levels of these grasses showed marked differences in near infrared radiation. Unfortunately, all pictures were taken from the ground. The second group of pictures was taken on June 3 0 , 1975, from the ground. Since growing conditions were excellent during June, very little difference between grass varieties was noted, I decided that aerial pictures would be more useful. A neighbor who is a professional photographer was employed to take the photos from a helicopter. He mounted two 35 m m . cameras to a single metal bar frame. A double cable release was used to enable both cameras to take matched slides. One camera used color film and the other infrared film. These pictures were taken July 3 which was the 15th day that daytime temperatures were 84 degrees or m o r e , so heat damage was beginning to take its toll. Aerial slides were again taken September 6 . By this date, daytime temperatures had exceeded 84 degrees on 54 different days. Heat damage to Poa annua had been severe. Much to my surprise, those slides showed that the bentgrass had filled in some areas of damage. Conclusions: 1. Aerial pictures are more informative than those taken on the ground. 2. Early spring slides are as important as are summer ones. 3. Good ground information is important when interpreting aerial photographs. 4. Both color and infrared photographs are important as a comparison. 5. Application or misapplication of chemicals can be very clear from the air. 6. Traffic patterns are very prominent from the air. 7. Water patterns from irrigation systems are amplified in the aerial view. 8. Poorly drained sand bunkers can be identified by the amount of accumulated silt. 9. The health of trees can be compared. 10. Infrared aerials aid in locating tile and irrigation lines. FIVE YEARS MANAGING A PAT FIELD Richard Kercher, Kercher Landscaping, Inc. Goshen, Indiana As I look back to 1972, the installation of the PAT System at Goshen High School was one of the most exciting projects I have ever been involved w i t h . The planning, the improvising were exciting and challenging, especially the challenge of never knowing for sure just what would happen - only what should happen as described by D r . Daniel. Needless to say, it all worked out, even better than we had hoped. By the second year we had an idea at least of what to expect, and this was the year we really began to get interested people from all over the United States in to view our installation. At the conclusion of 1973, we really began to feel we had an athletic turf that could take abuse, eliminate the wet field problem and still provide the plus factors that real turf could provide. Maintenance was very limited the second year and included only fertilization with 12-12-12 early in the spring and a feeding of IBDU in early August. A limited amount of plugging was done in some of the overworked areas along the 5 yard line in front of the goal posts. The third year we repeated the first year's process of aerating and topdressing with sand. This proved to give us improved wearing qualities and improved root structure so we concluded that aeration and topdressing with 30 tons of sand would be an annual practice. Our annual soil test showed that we needed to add some potash in addition to the basic fertilization program. For the 1975 season we again followed our fertilization-aerification and topdressing program. During the 1975 season D r . Daniel and I , with the help of some of the school employees, installed the automatic watering system. This consisted of installing five sensors at different spacings and depths in the sand of the PAT System with extension of wires to a meter which could be pre-set at any determined point. When a sand dried out so that the reading was below the predetermined set point, a water line electric valve, which was wired to the meter, opened and the PAT System received a charge of water back through the drainage lines. When the sensors indicated there was ample moisture again in the sand, the meter shut the electric water line valve off. This system worked well after it was installed until about the first of July when we aerated the field. From then on it became rather erratic. Weather conditions provided enough moisture, and time became a problem so D r . Daniel decided to try it in the greenhouse and next season we would make whatever changes might be necessary to try it again. The next spring, which was this past spring, we decided our problem had to be in our installation since the system worked fine in the greenhouse. We then dug up the sensors and the wiring, and would you believe our aerifying the previous season had been better than we realized? Needless to say, the new wires were buried deep enough so that during any future aerifying they will not be damaged. After a rather slow start, the 1976 season soon had us convinved it was a system well worth all the effort we had expended in getting it operational. I feel, for a high school football field operated with limited funds, limited management, and limited labor available, the automatic watering system is an excellent tool in keeping the turf in a healthy, growing condition. I feel the excellent condition of our turf this year was due in a large part to this watering system. Not once during the 1976 season was I ever aware that the turf had started to w i l t , nor was I ever able to determine that it was overwatered. Very briefly, these are some of the highlights of my five years with the PAT System. In closing, I would like to say the Goshen school administration and the people of Goshen have been grateful to D r . Daniel and all the other individuals responsible for the development of Prescription Athletic Turf. Community publicity and interest still remain high, and those involved in the school system feel they have a football field that is superior to any high school field in our area. ELEVEN PAT FIELDS W . H . Daniel, Turf Specialist, D e p t . of Agronomy, Purdue University West Lafayette, Indiana Many of those attending Purdue's Turf Conference know about the PAT System. It has received a very favorable press. Many of the people across the country, and even in other countries know of it. The system was created initially in an effort to provide a more satisfactory and dependable playing surface for athletic fields, regardless of the weather. In review, the PAT System has three major components: the suction system, conservation system, and subirrigation system with soil sensing. suction system is designed to remove excess water and to maintain a firm uniform surface for play. In design, this can handle one inch of rain per hour. Most of the fields have two large pumps. We have been pleased with this feature; it works well and fast. The second component provides for conservation of w a t e r . Because of the barrier, the moist sand is isolated from the subsoil. It is possible to retain maximum moisture after rain or irrigation. Further, because the water constantly redistributes above the barrier, it provides very uniform moisture distribution. The conservation system has worked w e l l , although the tendency has been to keep an excess of w a t e r . Experience and education have helped correct this. The third component of the PAT System is soil sensing and subirrigation. This means that when the moisture drops to a pre-determined level, based on soil sensing, the controller opens a valve so that the subirrigation can proceed throughout the drainage pipes above the barrier. In research we have found this feature effective. A meter that costs approximately $350.00 is the heart of the soil sensing component. A complete soil sensing system has been in use in the Goshen, Indiana, field since 1976. Several times during the season the moisture level has been reduced via the meter so that less water was applied. The rootzone then became drier which meant the roots would grow deeper. This procedure was possible because the manager of the area respected the sensors and was aware of their potential for indicating actual moisture content. This third phase of the system, subirrigation and automatic sensing, has not yet been installed on the other PAT fields. However, it is a part of the patent, USA 3,908,385 of 30 Se 75, and Canadian 985,516 of Mr 76, as granted to the Purdue Research Foundation. PAT, Inc., of Lansing, Michigan, is licensed for building PAT Systems in the USA and Canada. Today eleven PAT fields have been constructed and are in operation. The Goshen Field has been a model for experiments. In 1976, the fifth year of use, the Goshen Field was the best ever. Dick Kercher has managed this field. The bermuda field at Reitz Bowl in Evansville, Indiana, has been a signal success. It is reported they had two heavy rains there in the fall of 1976. When nearby fields were very muddy, the PAT field at Reitz Bowl was in excellent playing condition. Further, the Reitz team was in the state high school play-off so they used the field through the semifinals. That bermudagrass on sand is really tough. The field has been in for three years; they now have their fourth management crew operating. The turnover in staff has been a handicap. The Purdue Stadium, under the supervision of Mel Robey, co-inventor of the PAT System, along with Larry Davis, maintenance supervisor, was heavily used for spring practice in 1976. Of 21 practice sessions, 14 were held on the PAT field. It was badly w o r n . More than 100 players and coaches are on the field each time so the field was well tested. At the Mile High Stadium in Denver, Colorado, the PAT field is used for both football and baseball. At the Orange Bowl in M i a m i , Florida, the PAT System was outstanding in its first year of use. During the last game of the season, the turf cover still looked uniformly good. Jim McLean, part-owner of the Dolphins, recently commented 1 that the PAT field was 'fantastic , and that they were very pleased with its performance. The big story of the year was not the success of the Orange Bowl, but the lousy Monday night game in Washington, D.C. A game that everyone saw! The story is this. It had rained over one inch throughout the afternoon and continued to rain heavily, for 1.8 inches fell during the game. That is a lot of water. The original recommendation was for bermudagrass to be used in the initial planting of 1975. But to improve appearances, bluegrass was used instead. In 1975 the bluegrass tore badly. In April of 1976 the center of the field was resodded with a thick layer of soil carrying bermudagrass. No greensairing nor topdressing was d o n e . Then the big rain came on October 25! On Wednesday following the rain on October 25 (with another game scheduled the coming Sunday) they used two greensaires plus two topdressing machines on the bermudagrass portion to do what was specified and what should have been done six month earlier. Greensairing after sodding is needed to assure that the water can move vertically and quickly. Suction takes the route of least resistance. In Washington the suction pulled the water from the greensaired bluegrass along the perimeter but not the ankle deep water above the tight soil under the sodded bermudagrass. With the energy shortage the price of artificial turf has increased considerably. But so have other costs, including the installations of the PAT System. Concurrently, many colleges are operating on decreased funds, they have faced the explosion of interest in women's sports, and in some cases, a downturn in attendance at sports events. The funds available to build athletic fields have been limited in many institutions. Many athletic departments with older artificial turf that is badly worn are facing the question, "Shall we replace with a new artificial turf pad and cover or should we start over with the PAT System?" Both finances and the anticipated use of the area have to be considered. What is the future for the PAT System? With minor exceptions, the PAT System is a success. It has taken the natural turf fields from the muddy, grassless, hard and crusty areas to dependable, desirable playing surfaces available for repeated use. Professional players have expressed strong preference for natural turf. It provides a cooler and safer contact surface. PAT offers the professional image desired by players and spectators alike. ARTIFICIAL TURF UPDATE Glennori J . W a l s h , Executive Vice President Civic Center Redevelopment Corporation, Busch Memorial Stadium St. Louis, Missouri The AstroTurf playing field at Busch Memorial Stadium is now seven years old and going into its eighth year starting with the opening baseball game April 15, 1977. By way of background, for better understanding and evaluation of information to be presented later, the following is presented: 1. Use of the Field. Busch Memorial Stadium is leased to the Baseball Cardinals, the Football Cardinals, to universities, circus, high school football games, rock musical shows, e t c . There are approximately 80 Cardinal Baseball events, 10 Cardinal Football events, 4 circus dates, 2 to 4 NCAA soccer games, plus miscellaneous other event days so that there are approximately 100 events per year between early April and mid-December of each year. The Football Cardinals lease for the use of the stadium also provides that the football team has the right, and it has exercised that right through the years, to practice on the playing field each day so long as the football practices do not conflict with the baseball schedule. The latter is the prime reason that brought about a decision in 1969 to change from a natural grass playing field to an AstroTurf playing field. 2 . The AstroTurf playing field was constructed beginning late December 1969 and, unfortunately, work had to be started during the coldest and poorest construction weather conditions of the season and completed by April 1, 1970. 3 . After removing approximately 11" to 12" of the old field, capping water lines and repairing certain sections of the existing subsoil drainage system, 3" of porous material was spread over the entire field. On top of that, 8" of asphalt concrete was laid in three separate lifts, the last lift being approximately 3/4" to 1" thick, which was carefully installed to eliminate depressions that might pond w a t e r . A 3/4" energy absorbing pad was then glued to the blacktop and then the AstroTurf was glued to the p a d . The cost of the AstroTurf playing field in 1969 dollars was as follows: Site work (blacktop and rock b a s e , concrete trenches adjacent to all dirt base paths, pitchers mound, etc.) $ 277,000 3M Tartan warning track adjacent to the walls around most of the field Energy absorbing pad and AstroTurf grass Total 75,000 486,000 $ 838,000 Initially when the stadium was opened on May 12, 1966, a natural grass playing field was provided. The first playing season in 1966 was not a representative year because construction of the stadium continued up to the first game played in the stadium on May 12 and continued for several months thereafter. Because of daily practice by the football team all the grass was worn out. Prior to the 1967 season, the grass was completely resodded with a good quality zoysia, but overall the field was not satisfactory. Prior to the beginning of the 1968 season, the football portion of the field was sodded with Tifway-419 Bermudagrass, which provided a very satisfactory turf throughout the baseball season, b u t , as soon as the football team began its daily practices on the field iri early September, nearly all grass between the hash marks of the football field was worn down to the dirt and, of course, in the S t 0 Louis area the growth of Tifway-419 Bermudagrass ceases about Labor D a y . Overseeding and pregermination of the field with rye and bluegrass was unsuccessful mainly due to the daily football practices on the playing field. In 1969, the entire playing field was resodded prior to the beginning of the baseball season with Tifway-419 Bermudagrass and the turf provided an excellent baseball field until the football field commenced its daily football practices. The nautral turf field at Busch Stadium from 1966 through 1969 included seven major ideas provided by D r . Bill Daniel and D r . Ray Freeborg, who were consultants to us. It encompassed a 1 subsoil drainage system comprised of perforated plastic tile drains on 30 centers parallel to the center line of the football field, pop-up sprinkler heads over the entire field, which could be activated either manually or by automatic moisture sensors, which functioned quite w e l l .M A l s o , approximately 26 miles of heating cables, located approximately 4 below the surface of the ground which encouraged growth of the turf during the colder spring weather immediately prior to the baseball season and during the later part of the football season. During the four-year period of maintaining a natural turf field we engaged the professional services of D r . Ray Freeborg who worked with the field superintendent outlining maintenance programs throughout the year. Despite these efforts, it was finally concluded that natural grass would provide an acceptable playing field during the baseball season up to the time when the football team commenced its daily football practices on the field and shortly thereafter the turf was worn down to the surface of the ground. The above experience with a natural grass field caused us to install an AstroTurf playing field for the 1970 athletic season. ff We have been asked by m a n y , What is the life of an AstroTurf field?" It is impossible to answer the question because much depends on whether the AstroTurf field is located inside of a domed stadium, in an outdoor stadium such as Busch Memorial Stadium, in a warm climate where the full effect of ultraviolet light can take its toll on the nylon fibers of the AstroTurf and last, but possibly the most important, is the number of events scheduled on the playing field. In the case of the AstroTurf at Busch Stadium, we are now making a thorough evaluation of the replacement of the playing field for the 1978 season. We are considering artificial turf b u t , because of the high cost of replacing the field with an artificial turf, we are also giving consideration to natural turf. As long as daily practice by the Football Cardinals remains in the contract the use of natural turf is not practical. As was mentioned earlier, the total cost of installing the existing AstroTurf field in 1970 was $838,000 o The cost of installing the natural turf playing field in 1966 dollars was $244,000. To resurface the playing field with AstroTurf in 1978 would cost approximately $800,000, which includes an additional amount for the installation of a sliding box type of infield (like Cincinnati) rather than the extensive skinned area of the infield at present. For a comparison of natural grass, the maintenance and resodding each year for the years 1967 through 1969 averaged $119,000 per year w h i c h , projected to 1976 dollars is equal to $176,000. By comparison, for artificial turf the maintenance costs in 1970 totalled approximately $66,000 and for 1976 totalled $123,000. Therefore, there is a net saving of approximately $50,000 per year to maintain an AstroTurf playing field rather than a natural turf field. In evaluating the replacement of the playing field in 1978, consideration must also be given to which type of field, natural grass or artificial turf, is the best for athletes in terms of fewer injuries to players and in terms of providing the best playing conditions in all types of weather conditions. Such an evaluation is difficult because of conflicting information and data that have been assembled with respect to these matters. 1 The National Football League Players Association favors natural turf playing fields and claims that there are fewer injuries to players on natural turf. The 1 Players Association is also of the opinion that a football player's playing career can actually be extended by playing games on natural turf rather than on artificial turf. Other data assembled in the past by other interested parties (other than the 1 Players Association ) have concluded that there are fewer injuries on artificial turf. One significant difference in data with respect to 1 1injuries to players cenfl ters around the definition of what constitutes an injury? Should an elbow skin burn from sliding on artificial turf be counted as an "injury" in the same sense as a k n e e , arm, or shoulder injury that requires a player to leave the game? It seems the injury question is not conclusive to favor either natural turf or artifical turf. As far as which field provides the best playing conditions in all types of weather, this matter is debatable. It is difficult to argue that a good quality natural grass field on a dry day is not the best possible field on which to play a game, but on the other hand, would that same natural grass field provide the best possible playing conditions on which to play a game in the rain or after a 1" rainfall just prior to a game? A case in point was the Cardinal/Redskin game played on October 25, 1976, in Washington, D . C . which was viewed by millions of TV spectators on Monday night T V . The field on October 25, as millions of viewers can testify, was totally unsatisfactory for the playing of professional football. Of the 24 major league baseball fields, eight have artificial fields and seven of the fields are used also by NFL football teams. Of the 28 NFL football teams, 15 play on artificial fields, while 13 NFL football teams play on natural grass fields. Of the 13 natural grass fields, eight have major league baseball teams playing home games on the same field. At present, domed stadia (Dallas, Houston, Pontiac, Seattle, New Orleans) must have artificial turf. It is impossible, I feel, to attempt to conclude in favor of either an artifical field or a natural grass field for all open air stadia. The type of playing field must be selected based on an evaluation of the intensity of use, climatic conditions within the geographical area of the stadium, the cost of maintenance labor locally, the economic impact on the entity responsible for paying the cost of installing new fields, repairing existing fields, and the annual cost of maintenance of a field. COOL SEASON GRASSES David P . Martin, Department of Agronomy, Ohio State University Columbus, Ohio This paper will deal primarily with Kentucky bluegrass (Poa pratensis L.). It will deal with (1) the origin and development of Kentucky bluegrass and (2) cultivar evaluations as observed in Ohio. The Gramineae is one of the largest families of flowering plants in existence and covers a larger percentage of the earth's surface than any other single family The genus, Poa, numbering over 250 species, contains some of the most economically important grasses in existence. Poa pratensis L . is one of the most important pasture grasses in temperate climates and is undoubtedly unsurpassed in importance as a turfgrass. Some confusion exists in the literature and elsewhere in regard to the origin and development of this grass because of the large number of common names assigned to it at various times, including bluegrass, browntop, common meadow grass, common speargrass, English blue-grass, goose-grass, green grass, green meadowgrass, green Po a, greensward-grass, Indian bluegrass, June-grass, and Kentucky bluegrass. It has also been referred to as lawngrass, meadow-grass, prairie June-grass, red-top, Rhode Island grass, smooth stalked meadow-grass, spear-grass, spire-grass, summergrass, white-top, wire-grass, and yard grass. (1) Kentucky bluegrass is the name most commonly used to refer to Poa pratensis L today, even though it is a misnomer. Bluegrass was probably first used to refer to Poa compressa because of its apparent bluish cast, and then later used for other species of the same genus as w e l l . Because of the succulent, rapid growth exhibited on the limestone soils of the State of Kentucky, the grass was called Kentucky bluegrass by early colonists, a name that has persisted to the present time. There has been considerable investigation and disagreement on the question whether Poa pratensis L . is indigenous to North America. There are two lines of entry by which plants may have naturally come to North America from the Old W o r l d . One is by way of Greenland to Labrador from Europe and through Alaska from A s i a . Agrostologists consider it to be strong evidence that a given plant was introduced after the discovery of America if the range of the plant is not continuous through either of these routes (1). Poa pratensis L . grows well in temperate and cold climates including up into Canada, but is not native to Labrador or Alaska and is therefore considered an introduced species. In addition, very few species are indigenous to both Eurasia and the Western W o r l d . Since there is substantial proof that Poa pratensis L . is definitely indigenous to Eurasia, it would seem that this plant has been introduced to North America by m a n . Another source of information which sheds some light on the question is from old manuscripts of the early American colonies. The first direct reference is from William Penn when he reported sowing English grass seed in his courtyard in 1685 (2). There are a number of writings which referred to the absence of pastures in America compared to those in Europe. After being introduced, this grass spread very rapidly to Kentucky, Ohio, etc., and was assumed by later travelers to have been there all the time. The first persons there, however, found it conspicuously absent. Poa pratensis L . or English grass as it was commonly called then, was introduced along the East coast, perhaps by sweepings from cattle boats which would have had hay of this species aboard. It is fairly well documented that seeding of this grass did occur,and within 100 years English grass could be found in great abundance far to the w e s t . Had the grass been indigenous, it seems obvious that this procedure would not have been necessary or even mentioned. While this line of proof in itself may be open to some question, the wealth of information in this regard presents a good case. (1) Considerable plant breeding and cultivar development has occurred since the introduction of Kentucky bluegrass to the United States many years ago. However, most of this effort has taken place in the last three decades. As recently as twelve years ago a review of bluegrasses at this conference listed only eight varieties as generally available in the Midwest, another eight from European sources but not available, and eight more as experimental varieties. Today the list of commercially available cultivars is greatly increased along with evaluation of many more experimental selections. Kentucky bluegrass cultivar evaluation results for Ohio are listed in Tables 1 and 2. Many of these cultivars have provided high quality turf and are highly recommended for Ohio and surrounding states. Kentucky bluegrass blends consisting of three or four cultivars are more desirable for lawn-type turf than the use of a single cultivar. High quality blends are adapted over a broader range of soil conditions, cultural systems, and generally have fewer disease problems. Blends should probably be composed of a minimum of three cultivars and ones that have proven to be superior on an individual evaluation basis. A blend study at Ohio State over the last six years consisted of 38 different blend combinations. These blends have not shown the variation in quality during the season that individual cultivars have shown. In addition, most combinations have provided an excellent turf after six years and are very comparable in quality. References: 1. Carrier, L . and K . S . Bort. 1916.

Average of 2 years data ROUNDUP AND TURF USE Edward E . Jordan, Senior Sales Specialist, Monsanto Chemical C o . Carme1, Ind iana I will cover two aspects of Roundup. First, a review of the characteristics 1 or features of the product which will affect the performance, and hence the users satisfaction with the product. Secondly, a review of the present label and a look at the turfgrass label text recently submitted to the E P A . Roundup Characteristics or Features: 1. Safety with a 4900 oral L D 5 Q 2. Water solubility 3. Contains ample surfactant 4. Readily translocates to stems and root system for total destruction 5. Applied postemergence to green portion of target vegetation 6. Non-selective 7. No soil activity a. Tightly bound by soil particles b. Rapidly degraded by soil organisms c. Inefficiently absorbed by the plant roots 8. Broad spectrum control of both grasses and broadleaves 9. Negligible volatility In late 1974 we received our first label for industrial non-crop areas and farmsteads. Marketing in 1975 was restricted to this label. In 1976 the label was expanded to allow use and marketing of the product on areas prior to the emergence of corn, soybeans, sorghum (milo), w h e a t , oats, and barley. Monsanto recently submitted a label text to the EPA for permission to market Roundup in areas to be seeded to fine turf grasses. The objective to utilize Roundup in turf renovation in such areas as golf courses, parks, highway right-of-ways, e t c . The text included the following label instructions for use where existing vegetation is growing. 1. Omit at least one mewing to allow sufficient growth for good interception of the spray. 2 . Tillage or renovation techniques such as vertical mowing, coring, or slicing should be delayed for 7 days after application to allow proper translocation of glyphosate to take place. (This is particularly important where bermudagrass is involved.) 3. Seeding is unrestricted as to species and timing. 4 . Roundup does not provide residual weed control. Follow a label approved herbicide program in accordance to all cautionary statements and all other information appearing on the respective herbicide labels. Monsanto hopes the request to expand the present label to include the above practices will be accepted by the E P A . ROUNDUP AND EARLY SEEDING Jeffrey Kollenkark, Graduate Student in Turf, D e p t . of Agronomy Purdue University, West Lafayette, Indiana The purpose of this experiment was to observe any soil residual or inhibition activity of glyphosate when applied to soil, and if it has any effect upon the survival rate of different grasses. Glyphosate was applied to bare ground at 0 , 2.2, 3.4, 4.5 and 8.9 kg/ha o a May 19, 1976. Eight different grasses wer then planted on day 0 and day 3 . No observable differences were seen. Random seedling counts/unit area were made both 16 and 28 days following planting. No significance was found between rates. Germination was good even for planting day 0; it was significant, higher than planting day 3 . Table 1.

This equals the conctration that would be used to apply 2 lbs/A glyphosate in a 200 gal/A spray, such as might be used in hydroseeding. The time intervals used showed no difference compared to control. This would have application if existing foliage was not. dense. Seed could be applied at the same time. Where turf foliage is dense, spray application followed by delayed vertical renovation and delayed seed incorporation would be suggested. Table 1.

Shoulders, Turf Extension Specialist VPI and State University, Blacksburg, Virginia Many turf managers and specialists regard fertilizer as the most important tool in turf management. Fertilizer use affects color, root development, food reserves, vigor, density, cold and heat tolerance, and other factors associated with satisfactory performance. It can either enhance or counteract the effect of other practices of turf management. In Virginia and in similar climatic areas the rate and scheduling of applications on fertilizer, especially nitrogen,may account for the difference between satisfactory and unsatisfactory performance of temperate grasses including Kentucky bluegrass and the fescues. Consider the role and effects of the three major nutrients normally applied in fertilizer: Nitrogen - Nitrogen makes up 3% to 6% of the dry weight of turfgrasses. It is a vital constituent of the chlorophyll molecule, the proteins, the cell acids and enzymes and vitamins. Its application produces an immediate and marked response in the turf plant. Nitrogen affects rate of growth, shoot elongation, root growth, density, color, disease resistance or susceptibility, recovery potential 9 tolerance to heat, cold and drought, and even the composition of the turfgrass community. Phosphorus - Phosphorus makes up .1 to .6% of the dry weight. It is found in all living cells within the turf plant. It is involved in energy transformations including the trans formationof starch to sugar. The role of phosphorus in maturation and seed formation has long been recognized. Phosphorus is vitally important during the seedling stage when it promotes rooting and establishment. If ever deficient in soils, this is the critical period for low supply. Potassium - Potassium ranges from l-370 in dry tissue. It has a role in food formation and serves as a catalyst in nitrogen usage and other enzymatic reactions. Perhaps of greater interest to turf managers is the regulating effect potassium has on transpiration and respiration and its control in the uptake of certain nutrients. The positive effects of potassium include improving tolerance to heat, cold and drought, reduction of wilting through its influence on the intake and retention of w a t e r , improving tolerance to wear and increasing resistance to disease. This presentation is bluegrass and the fescues in Virginia. Warm season tirely different approach confined to the consideration of the response of Kentucky to fertilizer programs at Virginia Tech and elsewhere species such as bermudagrass and zoysia require an ento the scheduling of nitrogen applications. Furthermore, the assumption is made that the pH will be maintained at a level of between 6.0 and 6.5 to assure nutrient availability and uptake by the turf plant. It is also emphasized that the fertilizer schedules and rates are those w h i c h , over a number of years of experiments at Virginia Tech and practical use throughout the State of Virginia, have resulted in the most satisfactory turfgrass performance under the varied and frequently extreme climatic conditions that occur within the transition zone which lies between the areas where temperate grasses on one hand,the the sub-tropical on the other are best adapted. With climatic conditions as varied as ours the rates of nutrients and the time of year in which they are applied assumes major importance. The rate and scheduling of nitrogen applications is of greatest concern. Heavy applications of nitrogen in spring have resulted in severe injury, even loss of turf in summer under the transition zone climates. In Virginia normally 2 to 6 pounds of nitrogen (N) per 1000 sq.ft. is needed on general turf areas each year, the rate depending on the species and varieties involved and the level of turf quality acceptable. When using fertilizers in which the water insoluble nitrogen content is less than 507o of the total nitrogen, our experience has been that the most satisfactory schedule of application for temperate grasses is 3 applications of 1/2 to 1-1/2 pounds of nitrogen (N) per 1000 sq.ft. applied in September, November and December. An application of not more than 1/2 lb. of N in late May or June may also be needed if the turf exhibits a need for additional nitrogen that season. Table 1. Guidelines for Nitrogen Applications on Established Turf Areas in Virginia Month of Application September October-November December May 20-June Total Lbs, of Actual Nitrogen (N) Lawns General Turf Area per 1000 sq.ft Per Acre .5-1.5 .5-2.0 1-2 0-.5 2-6 20-60 20-80 40-80 0-20 80-240 The application schedule given in Table 1 has a number of advantages for cool season grasses under Virginia climatic conditions. It produces a greater root growth and food reserves, promotes faster green-up in spring, results in slower growth during the flush spring growth season, reduces the severity of spring and summer d i s e a s e s , reduces summer drouth problems and results in improved d e n s i t y , vigor and persistance. Satisfactory turf performance usually results w h e n phosphate and potash levels fl n remain in the Medium to "High" range as determined by soil test. (Table 2 ) . a nUnder c Virginia conditions maintenance usually requires from 1 to 3 lbs. each of î ^ s * K ? 0 per 1000 sq.ft. a n n u a l1 l y . Autumn is the preferred time for application of the major portion of the y e a r s needs for both nutrients on lawns and general turf a r e a s . Table 2 .

In V i r g i n i a , on most established lawns on high priority turf a r e a s , the problem is one of phosphorus over-fertilization in previous years and the need to limit further applications. Potassium may generate a moderate response w h e n applied to turf growing on soils low in p o t a s h , especially during stress periods. Little response is noted on general turf areas on w h i c h an adequate fertilization program is u s e d . Although the climatic conditions in Virginia are not the same as those in the M i d w e s t , I am confident that some of the trends in the response of turf to nutrient application we have experienced in Virginia will be useful to you in your further development of turfgrass fertilizer p r o g r a m s . W H A T KILLED IT? R . E . P a r t y k a , Plant Pathologist, Chem-Lawn Corporation D u b l i n , Ohio Although this conference centers primarily around t u r f , w e shall divert a trifle and consider the trees and shrubs that are so necessary to compliment good turf. In fact, have you ever seen a turf area that is utilized by the general public devoid of trees and shrubs? N o , you h a v e n ' t . Therefore, as maintenance people, trees and other woody plants should become a part of your responsibility along with the turf. One of the major concerns of woody plant material centers around their decline or d e a t h . This is disconcerting because of the time involved in growing a specimen p l a n t , located in a strategic position for symmetry or aesthetic v a l u e . The first suspected reason for plant decline now appears to be the plant growth regulator materials used in lawn maintenance programs. These materials can cause damage to woody plants if used improperly. However, these materials should f not become scapegoats for o n e s lack of knowledge of other problems that are being covered up. It is often too convenient to blame these growth regulator compounds when the plants die shortly after their use. It is better for one to have a reasonable understanding of how these plant regulator materials work and some of the symptom patterns that might be expected on foliage of plants where these compounds have been misused. The first group of materials is used to control the development of seeds. This group known as pre-emergent materials such as D C P A , bensulide, siduron, benefin, bandane and pronamide. When used at recommended rates these compounds do not damage established plant material, and therefore are not considered harmful to such plants. Caution must be used to prevent placement of the material in gardens or other areas where seeded material is to be established at a later date. A l s o , in lawn areas one should be aware that re-seeding will be delayed because such materials will prevent grass seed as well as weed seeds from germinating. Once seeds have germinated and broadleaf plants are established, another group of materials is used and generally referred to as hormone type compounds. These include 2,4-D, 2,4,5-T, M C P P , Silvex, and dicamba and are very effective in controlling broadleaf plants. One of the characteristic symptoms when plants come in contact with these compounds is foliage distortion. This may be severe petiole curl and leaf cupping, to twisting and reduced growth. However, since these are growth regulator type materials, symptoms arrear in actively growing tissue. Older mature tissue is generally not damaged when contact is made by accident or through wind drift. New growth also shows very distinct symptoms of parallel veination. This veination occurs when the leaf does not fully expand and the veins are very close together. If the new growth continues to show leaf distortion all season, one has to question if there is continued retreatment in the area or if an excessive amount was applied to the soil and the material is continually being taken up by the roots. This can happen if woody plants are accidentally fertilized with weed and feed materials. Another consideration is the placement of these materials in the vicinity of the root ball of a recent transplant. Watering practices may carry the material to the rootzone and put the plant in further stress in addition to the transplant shock. ' However, other forces may enter the picture with recent transplants as to whether proper procedures were followed in transplanting. In general, normal healthy plants will grow out of the damage caused by these materials provided there is no further exposure to the plant and rates in the soil are not above allowable levels. Post-emergent compounds are used to control certain grasses after they have become established. The arsonates are often used in these cases. However, pronamide is being used in some areas for specific w e e d s . When used properly, action is selective and slow with good results. These materials will also cause injury to woody plants if used close by or come in contact with the plants. The injury caused by these materials is very similar to the next group being discussed. Non-selective materials are often used around fences, driveways and trees to eliminate all vegetation. Some materials used for this purpose include dalapon, amitrol, Paraquat, and glyhposate. One consideration when using materials of this nature is water solubility and residual time in the soil. Too often materials besides the four listed are used and some may move to other locations and damage plants. A l s o , one should be cognizant of root systems of large trees and the possibility of root up-take of the compound placed at a seemingly safe distance. These materials may be slow to show symptoms on some plants and where they d o , there is no recourse left but to start with new plant material. Symptoms from these materials may vary. Some materials will cause outright death of tissue that becomes evident in 2-3 days time. Materials taken up by the roots may result in veinal or inter-veinal chlorosis depending on the active ingredient. Overall yellowing followed by marginal browning and death of the plant may be evident. A contact material may damage only existing foliage with regrowth taking place in a few weeks from the woody tissue. There are other factors to consider when one looks at woody plant damage and a knowledge of these factors is important. One important point is the weather, not only in recent weeks but 2-3 years prior to the time symptoms became apparent. This is especially important on larger established plants where weather records may help solve the problem. The age of the plant and transplant procedures need careful consideration on recently planted material. One cannot neglect diseases and insects as possible causes of similar problems. However, most organisms associated with woody ornamental problems do not kill a plant rapidly. In most cases, symptoms or signs are visible on the plant in time to allow remedial procedures to be implemented before the plant is killed. There are exceptions, such as canker, root diseases, or wilt inducing organisms, that often prove fatal by the time they become evident. Some of the most common causes of plant decline are not associated with the use of herbicides or insects or diseases. Rather, they relate to poor cultural practices that may become evident in a short period of time or may take several years to become obvious. » In a few cases, fluctuating weather conditions may produce mimicking symptoms that can be confused with other factors. A good example is late spring frost that damages developing buds. Leaves will develop but often appear as if eaten by insects. In other cases low temperatures after buds have expanded may produce foliar tissue that appears to have been damaged by herbicides. Situations like this require careful examination of the problem and good weather records of the area. The most disheartening prob Jem is that associated with brown or dying leaves on a plant. The symptom pattern may suggest a water shortage in the plant. The question is why and where is the damage evident. Some plants will react to extreme heat and dry soil conditions so genetic capability of the plant must be considered. This is often true of Buckeye, yellow poplar and sycamore in late summer. However, the symptoms on these plants often result in considerable leaf drop. Plants that do not drop leaves but show severe browning in most cases are suffering from a true water shortage that often leads to the death of the plant. A common cause of scorch or leaf browning on small recently transplanted material is a limited root system or a poor top-to-root ratio where water loss through the leaves is greater than root absorption. Planting too deep or too shallow and placing roots in different oxygen or water tension levels from normal will stress the plant. Lack of water or over-watering may damage certain root systems. Container grown plants that are root bound may fail to become established in soil and thus desiccate because of moisture shortage at the soil interfaces of the container and planting site. Older plants, 3-5 years old should be checked for girdling plastic twine around the trunk or plastic around the root b a l l . Deep planting may not become evident until this time especially if weather conditions were wet in recent years. Examine the trunk for mechanical damage or evidence of insect borers. Graft incompatabilities often become evident at this age. Older established plants may show decline due to girdling roots, construction damage in the vicinity of the roots or placement of excess soil over established root systems. Fill dirt may change oxygen levels in the soil and kill fine feeder roots. Mechanical damage or black top driveways over tree roots will eventually cause some problems if proper maintenance procedures were not followed at the time of construction. Last but not least, one has to keep in kind the physiological maturity of the plant and weather conditions in the past that may have put the plant in a stress situation. Probably one of the most important things one should remember about plant problems in an urba-suburban environment is that these plants are growing out of their natural habitats. The normal urban soil is in most cases a completely disturbed mixture of various horizons, compacted by heavy equipment, and subjected to the whims of a public often unknowledgable in the basics of plant growth. Until we develop plants that can tolerate these extreme conditions, problems will continue to appear to the chagrin of the maintenance people and the public. ARE YOU SURE THAT'S THE PROBLEM? R . E . Partyka, Plant Pathologist, Chem-Lawn Corporation Dublin, Ohio Probably one of the most difficult areas to diagnose a problem is in the home lawn. Not only do you have variable lawn sites, but you have home owners with different objectives and degrees of interest which will often determine the type of lawn throughout the season. In most cases, turf interest runs high in the spring after a long winter. At this time of year the turf is responding after a period of dormancy and, barring a few winter problems, it will look good in the spring. The home owner, in many cases, feels that he is at least partly responsible for a good looking turf. As the season progresses, homeowner interest may wane due to other interests and when other underlying problems become more apparent. At this time, customer calls are received by lawn service companies with the question, "What 11 did you do to my lawn? Diagnosing lawn problems in mid to late summer, in fact, almost any time, can be trying where there is little history known about the turf or area. Invariably, many questions must be raised and hopefully the homeowner will be able to answer them. Unfortunately, man has a short memory in many cases or else fails to keep adequate records. Then the diagnostician often finds himself in a quandry when investigating a lawn site. Certain questions and clues may bring him to the proper anwer, but in other situations laboratory work is needed to reach a more logical conclustion. Numerous factors must be kept in mind when troubleshooting a home lawn turf problem. One area includes general maintenance practices such as mowing height for the turf species and mowing intervals. Proper removal of top growth to maintain a good top-to-root ratio on the grass plant is important to maintain vigor. Careful observation of cut stubble will often determine this and in many cases, just a glance at the lawn will tell you how it is maintained. The area of soils is extremely important and probably creates more problems than anything else. Standard practice when building now is to remove all the topsoil, grade a lawn area with1 basement clay, and pack it with heavy equipment. On top of 1 this a thin layer of topsoil is placed, and a lawn established by seeding or sodding. The turf responds and looks good for a w h i l e . However, later stress conditions may develop where mineral deficiencies occur, soil moisture becomes inadequate, roots fail to penetrate to adequate depths and oxygen tension becomes too low for good root growth. At this time the turf becomes susceptible to other factors such as diseases, insects, or environmental conditions, and problems arise. Some remedial factors can be applied to restore the turf, but they are costly, must be done routinely, and in general, only a mediocre turf can be maintained because of a poor growing medium. The failure to recognize the amount of water needed to maintain turf often results in undue stress. This is due to the lack of sufficient w a t e r , improperly designed sprinkler systems, run-off rather than penetration, or a thatch build-up resulting in a shallow root system. The turf may fail to recover when improper watering programs and higher fertility levels are combined. Thus, problems that do develop on a home lawn are often interrelated with many factors. Most problems are stress related so case histories and good weather records are important for a proper diagnosis. When looking at a problem, an overall view is important. Similar situations may exist on other lawns in the area, and may be a key in diagnosis. Homeowners 1 see only their immediate area and are not concerned with other lawns unless others are better than theirs. Therefore, one should be aware of what is going on in the neighborhood. Once an overview has been given consideration, concentrate on a small or local area to determine if the pattern fits that of a specific type of problem. The symptom patterns of many pests are definitive. The next step should be to look at individual plants. Observing leaves, stems, crowns, and roots can often point to clues that are helpful in determining the problem. In cases where several factors may be involved, more work will have to be done by soil testing or other laboratory procedures to help pinpoint the problem. This is time consuming, and often a homeowner is impatient and expects you to solve the problem on the site. This may not be possible due to the degree of advancement of the problem. However, some recommendations can be made to start remedial procedures until a more adquate answer is found. Knowing the area and time of year will determine what should be done. In cases when temperature and moisture stresses are involved, just watering may be sufficient. Of course, the old f, 11 answer of, I water plenty - just look at my bill! comes u p . Just convincing the homeowner to soak one spot for 24 hours will often show a remarkable recovery of the turf and help to prove a point. Knowing the types of problems that can occur and at what time of the year is very important in diagnosing. Early spring problems are often associated with snow mold damage to turf. This may be true if the snow accumulated excessively in certain areas. Recognizing the dark sclerotia of Typula sp. embedded in the tissue or the pink mycelium growth of Fusarium nivale will often determine if this is the problem. However, one should be aware of other factors that may confuse the issue, such as desiccation injury on high spots or around corners off the building, ice smothering along drives and walk-ways or where children s snow forts were constructed, salt damage, or low areas subjected to freezing and thawing conditions in late winter. As the season progresses, melting out symptoms may be similar to sod webworm or billbug injury. Careful examination for insects or their damage will help separate the problem. Dollarspot and red thread on home lawns, from a distance, looks similar to dog urine or mower burns. Close examination will reveal typical leaf symptoms of dollarspot and coral pink fungal strands on the ends of the blades will identify red thread. Stripe smut can be readily identified by the sooty spores in the infected blades and general unthrifty appearance of the diseased turf. Slime molds and powdery mildews are often present in turf but only powdery mildew is serious in shady areas. Fusarium blight has become a serious disease in many new improved turfgrass varieties. A common symptom pattern, the frog-eye effect, has become associated with this disease. Unfortunately, many other diseases may form a frog-eye symptom. In general, Fusarium blight kills the crown of the plant. Brown patch fungus injures the roots and leaves, but the crown will remain visible for a longer period of time, and if weather conditions change the plant will recover. Pythium blight, a hot weather disease, is more common on ryegrass. It is generally identified by fungal growth during humid conditions and the matted collapsed appearance of diseased turf. The appearance of rust and fairy rings can be readily identified. But yellowing of turf in definite areas requires much closer scrutiny. This may be associated with mineral deficiencies, nematodes, yellow tuft, aphids or inadequate root systems on the plant. Soil testing is often needed. Other problems should not be excluded. Drought stress may appear similar to a disease problem when it starts. Root competition with trees weakens the turf and may resemble a disease or insect problem. Brown spots may be fertilizer, oil or gasoline spill, heat reflection from a muffler or footprints on frozen turf. Erratic patterns in narrow lines are oftendue to mouse damage, but may be vandalism as w e l l . How the turf recovers or a close look at the crowns can determine the cause. Diagnosing home lawn problems is a definite challenge. It can be frustrating for an irate customer, but rewarding when you find the answer. DIFFERENCES IN LAWN RESPONSE - WHY? Jeff Lefton, Agronomist, Chem-Lawn Corporation Indianapolis, Indiana One difficult question to answer deals with two lawns nearff each other, both with a lawn problem responding differently. The question is asked, Why doesn't my lawn 1 H look as good as my n e i g h b o r s ? One approach is to consider realistic possibilities and eliminate them one at a time. Below I have listed several factors to consider when comparing two lawns. 1. Consider a sun lawn v s . a shaded lawn. like a sun lawn. A shaded lawn will not stress out 2 . Differences in soil - topsoil v s . subsoil; compacted (traffic) v s . uxucompacted soil; natural drainage differences (slope); natural fertility and pH; the variability in soil texture within the lawn and from lawn to lawn; and the differences in soluble salt levels. 3 . Differences in grasses - consider the age of the lawn; contamination with Poa trivialis, Poa annua, nimblewill, and bentgrass; poor coloration from improved varieties of Kentucky 11 bluegrass such as Merion or Windsor in early spring and late fall; and a ,f heading out problem (seedhead formation) from Kentucky bluegrasses such as Newport. 4 . Mowing habits 1 1 - compare height and frequency of cut; dull v s . sharp mowers; and a "stalking effect from natural upright growing grasses (annual ryegrass, orchardgrass, etc.). 5 . Differences in the nature (thick v s . loose thatch) and the depth of the thatch (greater than 3/4" is a problem). 6 . Differences in watering programs - frequency and duration of watering; and a consideration of the natural moisture levels. 7. Consider the application dates and the type of lawn care program: a. When did each lawn start on the lawn care program? b. When were the various rounds applied to each lawn? c. Were the chemicals in any particular round different on either lawn? d. Did either person supplement the regular lawn care program with additional lawn products? 8. The difference could also be explained based on one lawn having a disease or insect problem. From a customer relations standpoint, it makes sense to prepare yourself to systematically approach lawn problem solving.
