NORTHWEST TURFGRASS TOPICS VOLUME 9, No. 3 PUYALLUP, WASHINGTON DECEMBER, 1967 THE EFFECTS OF UREA ON SOIL pH AND CALCIUM LEVELS FROM THE PRESIDENTS CORNER By George Harrison Our association was recognized as a representative of an important agricultural business when your president was asked to be present at the welcoming dinner for Dr. Terrell, the new president of Washington State University. Members from firms in all types of agriculture were there to acquaint the new head of the university with various aspects and problems of their businesses. It was interesting to note that many of their problem s were ours, i.e. shortage of trained labor, wage rates increasing, increased capital equipment needed. It had a very familiar ring. Dr. Terrell made an interesting point that the university is not only interested in solving technical and research problems but, also, in solving human problems. (Remember the talk on urbanization and its problems at the conference?) We wish him well on his new challenge. We are all acquainted with the fact that the costs of research and all technical progress are going up fast. To make the same effort this year that we have in past years is going to require more funds. These funds come from our memberships. Let s take the form T [Continued on Page 3] By Roy L. Goss Soils are complex chemical, physical, and biological systems. The continued use of fertilizers, especially in large quantities, may produce marked changes in these systems. It is obvious from the tabled data that rather large changes have occurred in calcium levels and pH values since research was started at the Western Washington Research and Extension Center. The table indicates what the soil pH and calcium levels were in 1959 and the existing levels in 1967. These putting green plots have received three levels of nitrogen (20, 12 and 6 pounds per 1000 square feet per season) two levels of phosphorus (0 and 4 pounds P2O5 per 1000 square feet per season), and three levels of potassium (0, 4 and 8 pounds K2O per 1000 square feet per season) in all possible combinations during this period of time. No calcium in the way of lime or other amendments has been applied to these plots. When 20 pounds of nitrogen per 1000 square feet from urea was used, regardless of phosphorus and potassium levels, soils are ten times as acid as when 12 pounds of nitrogen from urea was used with the same phosphorus and potassium levels. The pH change which occurs when urea and nitrogen is reduced from 12 pounds to 6 pounds per 1000 square feet per year is not significant, but the difference between the 6 and 20 pound rates is highly significant This change has been in a gradual downward trend since fertilization was started and proves the necessity for maintaining accurate and current soil tests. The Effect of Fertilization on Soil Calcium Reserves The table shows soil calcium levels after 8 years. It is interesting to note that treat[Continued on Page 4] May 6,1968.

Election of officers of the Oregon Turf Management Association was held in October . The total membership agreed to overwork Mr. Richard Malpass, Supt., Shadow Hills Estates Golf Club, Junction City, Oregon, and to re-elect Richard for another twoyear term as our President. Richard has many accomplishments to look to his first two-year term as President. Financial assistance in grants to students intereste d in the turf management field, a never-ending effort to assist and visit those superintendents who called upon him for service, a keen effort to get a turf research program going here in Oregon and, of course, his loyalty to the office of President, Oregon Turf Management Association. First Vice President is Mr. Frank Zook, Superintendent, Green Meadows Golf Club, Vancouver, Washington. This is Frank s T OREGON COMPOST HEAP By Byron Reed We have just completed a most successful golf season here in Oregon. Oregon* s weather was sunny and dry, some 100 days, I believe. It brought increased problems for the Golf Course Superintendents in turf management coupled with long hard hours of effort to keep the golf courses in playing condition. Compliments are surely in order for the Golf Course Superintendents in the state of Oregon. For those readers who may wish to visit a meeting or two of the Oregon Turf Managers Association during 1968, I am listing our meeting schedule. We are anxious to have out-of-state visitors.

Richard recently moved from Bend, Oregon, where he served as the Superintendent of Bend Golf Club. We believe Richard to be great officer material which, of course, is so necessary to keep our Oregon Turf Management Association growing. One could use such words as Alpha and Omega to cover our Mr. Ray Garner, Secretary and Treasurer. I just don t know how we could have survived without the services of Ray and his tireless effort in behalf of the Oregon Turf Management Association. It is hoped that Ray will gather some small pleasure of this mention. Oregon will experience the largest golf club openings during 1968 in its history. I will cover this in the next column. Editor s Note: The editor wishes to point out that Byron has manned one of the toughest positions in his organization in maintaining a good educational program for the members. Certainly, he is to be commended for this important job. T T FROM THE PRESIDENTS CORNER [Continued from Page 1] enclosed in this issue of Turf Topics and present it to anyone you know who is a logical prospective member. You would be surprised how many people with a stake in the turf industry do not know that we exist. Show them your copy of Turf Topics and the Proceedings from the last conference so they know the help we are giving them. Here in the Puget Sound Basin, October was as wet as the summer has been dry. Numerous incidents of disease were noted. Those on the regular preventive maintenance spray schedules seemed to be pretty much in control, but the man who skipped was distinctly penalized. We certainly hope that Dr. Gould has returned from Europe with some new ideas that will help in this disease cure and prevention fight. Some notes taken while traveling -- Jim Ticehurst of Cascade Golf had reservations at Harrison Hotel for the conference, but the night before he was to leave he wound up in the hospital with stomach problems. He is back on the job again and plans to make the next conference for sure. — Cecil Thompson at Si View Golf Course had great success with bringing dired fairways back into play by applying one pound of nitrogen from ammonium nitrate to the grass in late August. The first moisture really turned them green gaining nearly two weeks over adjacent areas that had not been fertilized. — The new Nile Temple Course is rapidly rounding into shape. They plan to open for play in April if all goes well. ~ I understand that the Seattle Public Courses have ruled off carts for the duration of the winter. Seems like an excellent idea for some other courses that take such a beating from the compaction caused by those wheels. — Many cemeteries are reporting great success in using Casoron in ornamental plantings for pre-emergent weed control, but there have been reports of damage to turf where applications drifted. These chemical tools are great but must be used correctly. — The University of Washington Arboretum is offering pruning instruction in their Continuing Education Courses. Seems like an easy way to get instruction to your key men in this important winter job. — How many of you are receiving the "Chewings" bulletin that Art Mehas in the King County Extension Office publishes? It keeps you up to date on the current horticultural problems and some of their suggested cures. - - Had a cemetery report that a smooth talking salesman offering weed killers at twice the local price came swinging through the territory. Gave real nice pen and pencil set premiums and other goodies.

Furthermore, the two lowest calcium levels (in treatments 5 and 6) received no phosphorus; however, 1967 soil tests show both of these plots to be very high in phosphorus. The pH value of these two plots is very low (4.2 and 4.3, respectively) and may be low enough to render phosphorus unavailable or at least less available. It also appears that the lack of phosphorus application causes a greater uptake of calcium and a resultant lowering of pH. The same trend can be seen in treatments number 7 (12-0-0), 8 (12-0-4) and 9 (12-0-8). All treatments with low calcium levels also rate lower at the present time than those with higher calcium levels in color intensity. The lower quality turf in low calcium plots may be associated with deficiencies or excesses of other nutrients that are affected by low calcium and pH. It is known that lime makes conditions favorable for nitrification and sulphofication, according to certain authorities. In our case, sulfur may be the limiting factor and, in fact, in other current trials we are finding that sulfur greatly improves the quality of turf in both color and vigor on these low calcium and low pH plots. This has previously been reported in articles relating to sulfur nutrition. Soil Reaction and Diseases When plots were first established at the Research Center at Puyallup, the average pH, as noted in the table, was between 5.7 and 5.8. At this time a considerable amount of Ophiobolus patch disease was encountered. Within the next three years after the initial outbreak the amount of disease began decreasing and became specifically located in certain plots which was attributed to phosphorus and potassium levels. During this period of time when disease decreased, soil pH values likewise were lowering. This tends to indicate that less Ophiobolus disease is usually found when soil pH values are on the moderate to strong acid side. It is believed by the writer that pH is not the most critical factor when considering both calcium levels andpH values. If the soil contains adequate calcium, slightly depressed pH values probably are not so important as when low pH values are encountered at the same time. Turfgrasses, particularly the bentgrasses, have the ability to do well under low pH conditions. Although low pH levels can render phosphorus less available, turfgrasses use only small amounts of phosphorus. In the case of bluegrasses, however, it is generally felt that higher pH values and higher levels of calcium are necessary for proper growth and longevity of this grass. Table 1.

Harrison Hot Springs, British Columbia was a beautiful setting and location for the Conference and I am sure was enjoyed by all who attended. The weather even cooperated in staying very nice throughout the Conference and, in fact, most of the turfgrass managers in attendance would have welcomed some badly needed rain. The conference was called to order and welcomed by Dick Malpass, 1966-67 President of the Association, who turned the meeting over to Dick Mitchell, the presiding afternoon chairman from Shaughnessy Golf & Country Club, Vancouver, British Columbia. The first afternoon speaker was Walter Boysen, President of the Golf Course Super- intendents Association of America from Oakland, California. Walter gave a very inspiring talk on past, present, and future of the golf course superintendents. Mr. Boysen has been in this field many years and since he has been in contact with superintendents all over the nation is very qualified in his remarks. I am sure that everyone in attendance profited by his talk and private conferences. Dr. J. B. LeBeau, Plant Pathologist from the Canada Department of Agriculture, Lethbridge, Alberta, presented some interesting data on the effect of snow mold and some other low temperature organisms in the prairie provinces of Canada. He reported on the success of the various fungicides, and a minor report on soil heating. Bill Bengeyfield from the U. S. Golf Association, Green Section, Garden Grove, California, gave a thought-provoking discussion entitled "We are Going to be Challenged". Bill's talk included everything in this field from artificial turf on up through professionalism of the golf superintendent, and other turfgrass managers. The costs of managing turf were pointed out and that carefully palnned budgets and operational procedures will be very important to the turf manager in the future. Parks are Becoming More Important A panel discussion relating to the designing, building and maintaining of public parks was capably handled by Mr. Pavil Beistel from Eugene, Oregon, and Mr. John Sandusky, Seattle Parks Department. Mr. Beistel showed some very beautiful slides on the development of parks in Lane County, Oregon, IT'S TIME TO LIME Grass will not grow without sufficient available CALCIUM! Kiln dried - Fine ground limestone flour HEMPHILL BROS., INC. Seattle MA 2-4277 J. A. JACK & SONS, INC. High calcium, sacked, bulk or spread the amount of use these parks were getting, and some of the planning and thought that went into recreational areas for the public. Mr. Sandusky pointed out many of the engineering problems associated with soils, drainage, and subsequent maintenance of park areas. There are many hidden costs that many of us may not take into consideration that require some rather large budgets. Mr. Gerald Pelton of the National Parks and Recreation Association from Seattle, Washington, was asked to join this panel and presented some excellent information on the continuing need for more parks and more recreation areas and how the National Parks and Recreation Association fits into the total picture. New concepts in turfgrass fertilizers was capably handled by Dr. Jim Beaton of the Consolidated Mining and Smelting Company of Trail, British Columbia. Jim gave a brief look at the future of some new fertilizers that will be coming into agricultural business in the next few years and pointed out that industry was making an effort to keep ahead of today's needs. Toby Grether of the Cal-Turf Nurseries from Camarillo, California, gave a beautifully illustrated talk on the uses of stolons for turf. Mr. Grether described their operations and research program connected with stolons and sod and described some of the techniques of handling these materials. Babe Brinkworth of the Toro Manufacturing Corporation gave an excellent illustrated slide talk on preventative maintenance of grass-cutting machinery. Babe pointed out some of the age-old problems of neglect, as well as the good side of machinery maintenance, that would give it more or less life, depending upon its use. Dick Turley from the Canada Department of Agriculture at Saanichton, British Columbia, presented an extremely useful talk on turfgrass irrigation. Contrary to much popular opinion Dick reported in his experiments that light, frequent irrigation maintained a higher level of soil moisture available for plant use than the infrequent heavy applications of water. Dick Haskell, Director of Golf, City of Seattle, presented a great deal of information about public golf courses in a very short period of time. He pointed out many features such as the golf architect, selecting the site, and design of the public course for safety, playability, ease of maintenance, and many other essential features that go into making a good public golf course, even when total application was the same. Among the other speakers were Alvin G. Law, Washington State University, Pullman, who talked on the advanced training for turfgrass managers. Dr. V. C. Brink, University of British Columbia, who talked on turfgrass texture, and Roy Goss who talked on developing specifications and plans for constructing turfgrass areas. The Conference was terminated with a research report from the Western Washington Research and Extension Center, Puyallup, and research being conducted at the University of British Columbia.

BACKED BY BEST RESEARCH HIGHLIGHTS OF THE AMERICAN SOCIETY OF AGROMONY MEETING FOR 1967 By Roy L. Goss Division C-5, Turfgrass Management, has become a permanent part of the Annual Meetings of the American Society of Agronomy. In 1967 there were 25 papers presented in Division C-5 from research personnel from nearly every part of the United States. A number of interesting papers were presented on protecting cut and fill slopes for erosion control and establishment of turf and the various means of mulching and holding the soil in place. Carbohydrate storage, soluble protein fractions, and the ability of the plant to withstand extremes of temperature, were discussed in several papers. The ability of the plant to withstand certain extremes is closely associated with some of these soluble fractions. Turfgrass Nutrition Nutritional problems are always foremost in management. Two complete sessions were devoted to turfgrass nutrition. Session number 3 was general nutrition, and papers were presented by researchers from Iowa State University, Alabama, O. M. Scott and Sons Co., Hercules Powder Co., VPI, Michigan State University, and Texas A & M University., Although all these papers were well presented and had significant data, one of the most interesting was that presented by Dr. D. G. Sturkie from the Alabama Agricultural Experiment Station on the response of Zoysia and Bermuda to phosphorus and potassium. Although we are not interested in these grasses in the Pacific Northwest, the interesting thing was these grasses showed differential responses to varying levels of these two elements. Current research at the Western Washington Research and Extension Center indicates some similar relationships to those reported by Sturkie and these interrelationships are becoming even more clear-cut as the level of elements in the soil is lowered. Potassium Symposium A special symposium on potassium nutri- tion of turfgrasses was presented by R. E. Wagner of the American Potash Institute. W. B. Gilbert of North Carolina State University; Roy L. Goss, Washington State University; C. L. Foy of VPI; and Granville Horn, University of Florida. These five papers endeavored to present as much information as possible regarding the role of potassium in the metabolism of turfgrasses, some of the relationships of potassium nutrition and temperature stresses, the effect of potassium on turfgrass diseases, the influence of potassium on herbicides, and the response of turfgrasses to potassium source. Dr. R. E. Wagner pointed out that potassium is necessaryior the function of more than 25 different enzymes and is very necessary in both carbohydrates and protein metabolism. Gilbert from North Carolina State pointed out there were some relationships between the level of potassium and the ability of grasses to withstand higher heat and cold stresses. Goss, from Washington State University, pointed out that he and C. J. Gould had found significant relationships between levels of potassium and other nutrients on the occurrence of Fusarium patch, Red thread, and Ophiobolus patch diseases. C. L. Foy reported that there was little information available on the effect of potassium on herbicides, but did point out that proper nutritional balances were necessary for the best uptake and effect of applied herbicides. Granville Horn from the University of Florida, showed significant relationships between potassium sources and their effect upon turfgrasses. Potassium sulfate was one of the best sources for general turfgrass nutrition and this is possibly due to adequate levels of both potassium and sulfur. Since a great deal of work has not been conducted on sulfur nutrition, it is not known just what levels of sulfur are required. However, it appears that more work will be forthcoming in the near future. Dr. Coleman Ward from Mississippi State University served as chairman of Division C-5 for 1967 and did an outstanding job of bringing together all speakers from over the nation and keeping the Conference running smoothly. 1967 CONFERENCE ATTENDANCE 1.
