I f there is good here, we want to share it with all chapters - unless author states otherwise. Now that fertilizer costs have skyrocketed maybe Spring feeding will be cut down. Probably one of the biggest factors in Spring feeding is the demand by the membership for color. One of the advantages of dormant feeding is that you do get the color but not the lush growth which is usually the case with Spring applications of fertilizer. Also if you happen to hit a cold Spring the tendency is to put just a little more fertilizer out when the grass hasn’t responded (mainly because the soil is just too cold). We are glad to hear Dick DePencier is recovering nicely from a back operation for a pinched nerve. Now that the turf conference circuit has just about finished and vactions all enjoyed we can expect a big turnout for the April meeting. Attendance at the March meeting was a little low. So be sure to bring your neighbor on the 16th. We have an excellent program lined up. If you haven’t already, please send in your dues now. Mr. Richard Browne has been approved by the Executive Committee as a Class A member. Dick is the new Superintendent at the Greenwich Country Club. Welcome to MGCSA Dick. IN MEMORIAM Lawrence Labriola—We certainly will miss Lawrence Labriola. He was an honorary member of the MGCSA. A dear friend of the golf course Superintendent and a man who over the years helped our association in many ways, with the golf prize fund, and his annual picnic. He also had done various construction work on many of the golf courses in the area and certainly much of his nursery stock can be found on the golf courses in our area also. All the members of MGCSA extend our deepest sympathy to the Labriola family. GOLF COMMITTEE — Terry Mulligan HANDICAPS: MGA or Club handicaps will be used at all MGCSA golf outings and tournam ents. Those members not having an MGA or Club handicap will start the season with last years handicap and we will try to compute your handicap as the season progresses. Please turn in all score cards, don’t just record your score on the tournament sheet. Tournaments: This year we will try to get away from kickers at each golf outing. We plan to have different types of individual events. We also would like to have a fourball tournament. The players are paired in two-man teams and their better ball on each hole is the team score. Each player will be allowed 100 percent of his handicap, the strokes to be taken as they come on the card. If enough interest is shown and enough teams enter this tournament could be implemented by the May meeting. Pairings would be posted in the Tee to Green. Hole-In-One: It has been suggested that all golfing members of MGCSA pay $2.00 for Hole-InOne Insurance to protect anyone, who is fortunate enough to get a hole in one, from going bankrupt at the 19th hole. PLEASE EXCUSE OUR ERROR We neglected to credit the articles in last months issue on the Rutgers Turfgrass Conference and the U.S.G.A. Greens Section Meeting to Scott Benty.

The University of M assachusetts hosted its annual Turfgrass Conference at the Highpoint Motor Inn in Chicopee, Massachusetts March 6th, 7th, 8th. Dr. Joseph Troll was at the controls again. He has a unique quality of improvising his program each year, and 1974 was no exception. This conference was a reunion for many superintendents, but for me it was very special. For it was at this same time last year that I graduated from “Winter School” and was fortunate enough to secure a job at Winged Foot Golf Club. I know from experience how the students felt about interviews and meeting some influential people in the turf field. Students are nervous and apprehensive about their futures. They desire a job and a great future, and they desire it immediately. This feeling is natural for all and an experience which we all go through at one time or another. However, life does not work as quickly as we sometimes desire. A good future must be built upon a strong and well planned background. Just as the architect builds a new home, he must secure the foundation to assure that the structure will weather the change of seasons. To those students who found jobs, I suggest that you work hard and plan well. For those employers who have hired new students, be patient, guide them as best you can. Remember, you are training the future of your profession. A well planned conference is one which runs on time and is comprised of knowledgeable speakers. Superintendents at­ tending the U. Mass. Conference found both of the above under one roof. The proceedings were scheduled very well. A broad spectrum of speakers made the conference exciting. Mr. William Buchanan representing the U.S.G.A. hosted a panel of superintendents rehashing the “Summer of ’73.” Dr. Robert Carrow representing U. Mass., conducted a similar panel discussion on tricalcium. Dr. Houston B. Couch delivered an amusing talk on what to do in case we see another devastating summer. Mr. Richard Silvar representing the Pinehurst Golf Club, which is run by the Diamond Head Corporation, related his job of managing several golf courses. Mr. Edward Horton delivered a powerful presentation concerning the operation of a high budget golf course. Congratulations should be extended to Dr. Troll for his excellent organization of the conference and for securing a well rounded panel of speakers. I look forward to next years conference with enthusiasm and high expectations.

Morgan NUTRIENT STORAGE AND MOVEMENT UNDER TURF In the 1972 Purdue Turfgrass Conference Proceedings, Dr. Paul E. Rieke of Michigan State presented an article on Nutrient Storage and Movement under Turf. His information principally concerned nitrogen, phosphorus, and potassium. NITROGEN Nitrogen warrants such attention because it affects the turf in so many ways. Included are shoot growth, shoot density, root growth, color, tolerance to temperature and moisture stress conditions, disease susceptibility, wear tolerance, recuperative potential, and competition of the turfgrass with weeds and other turfgrass species. Nitrogen is added to the soil by fertilizing, in rainfall, and by nitrogen fixation carried on by certain soil microorganisms. In addition, nitrogen can be added to the soil in top dressing material, included with peat, manure or by clippings returned to the turf. Clippings return is merely a recycling of the nitrogen already present. If one assumes that 200 pounds of green clippings (80% moisture) are returned to the turf per 1,000 square feet annually and that they average five percent nitrogen (dry weight basis), this amounts to two pounds of nitrogen being recycled in the clippings. This amounts to a very light fertilization with each mowing with ready release of N. Higher values would be evident if heavier nitrogen applications or a longer growing season prevailed. The reservoir of nitrogen tied up in the soil organic matter is an important source of nitrogen when soil temperatures are warm and peak microbial activity occurs. Mineral soils might contain about 0.15% nitrogen by dry weight. Most of this nitrogen is essentially unavailable for the turf to use since soil organic matter in mineral soils is usually relatively resistant to further decomposition. Nitrogen losses by leaching can be appreciable if sound management practices are not followed, especially on irrigated sands. A soil nitrate study included several nitrogen fertilizer treatments, which were applied to Merion Kentucky bluegrass. Data were obtained in 1970 and 1971 from the 0-6, 6-12,12-18, and 18-24 inch depths. When very high rates of nitrogen (6 to 8 lbs. per 1,000 sq. ft. annually) were applied in soluble form (ammonium nitrate) in April, there was appreciable leaching. When this treatment was divided into three applications during the growing season, the apparent leaching of nitrate into lower horizons was much reduced. Use of organic (or slow release) nitrogen carriers—milorganite, ureaformaldehyde and isobutylidene diurea reduced the nitrate levels in the soil during spring and early summer; but in late summer, the nitrate levels in the subsoil (to 24 in.) were somewhat higher than in plots receiving ammonium nitrate in 1970 data. The 1971 data suggests similar trends except a very dry summer and limited irrigation resulted in very little nitrate nitrogen appearing in the soil, even in the 0-6 inch depth. This was attributed to the nitrogen fertilizer particles staying in the thatch layer, which was discarded when the soil was sampled. On the basis of these studies we have prepared guidelines on nitrogen fertilization to keep nitrate leaching to a minimum. 1. Use no more than 1.5 pounds of nitrogen per 1,000 square feet (60 lbs. per acre) on turf in any one application. 2. Apply nitrogen only to actively growing turf. 3. On sandy soils use irrigation judiciously to reduce leaching. 4. If clippings are returned, reduce nitrogen rates accordingly. 5. Use slow release forms of N. 6. On sandy sites, especially where water sources could be contaminated with nitrates, it is well to consider the use of low nitrogen requiring turfgrass. PHOSPHORUS Phosphorous does not leach readily through soils. Most soils have a high capacity to tie-up phosphorous either by attraction to the clay particles, or by forming less soluble iron and aluminum phosphates if the soil is acid, or calcium phosphate if the soil is alkaline (above pH 7.0). An example of the tendency for phosphorous to collect in the surface soil is illustrated in data taken from one of our research plot areas. The 0-2 inch depth had a soil phosphorous test of 70 pounds per acre. The 4-6 and 8-10 inch depth samples tested 25 and 6 pounds phosphorous per acre, respectively.

When arsenates are being used for Poa annual control, phosphorous applications should also be restricted since an application of phosphorous containing fertilizer can offset the arsenate influence. POTASSIUM Potassium is a cation (positively-charged); as such, it is attracted to the cation exchange* capacity (negatively-charged) on clay minerals and soil organic matter particles. This tends to hold potassium from leaching through the soil. It can be leached, however, with excessive irrigation, especially from sandy soils. Also, ammonia applications favor leaching of K by replacement. More frequent and usually higher potassium rates will be required on heavily irrigated sands to account for the greater leaching losses. Data in Table 1 show the tendency for potassium to stay near the surface of a fine sandy loam soil. Increasing nitrogen rate caused a decrease in soil potassium test due to greater amounts of potassium removed from clippings. TABLE 1 Soil potassium tests as affected by depth of sampling and rate of nitrogen application.

This takes potassium out of soil solution and prevents its leaching, but it is not available to the plant until it is released from the mineral again. Soils, which have such minerals, may contain great quantities of potassium; but soil tests may not be high. On such soils, response to potassium may not be apparent. OTHERS Calcium and magnesium are closely related to soil pH. If pH is acceptable for the turf, both of these nutrients are usually present in adequate quantities in the northern mid-west. In some cases a need for magnesium may occur. Soil testing is the best means for determining magnesium needs. Sulfur can be leached from the soil in the sulfate form. Heavy rainfall and irrigation, especially on sandy soils, contribute to sulfate leaching. Reports of sulfur responses on turf are most common in Washington and Florida. This need for this nutrient will probably become more widespread as more stringent air pollution controls are employed, which will reduce sulfur additions to the soil by rainfall. The micronutrients, iron, manganese, copper, and zinc are normally present in much more than sufficient quantities for turf. If soil pH is too high, however, they are often not in available form. Deficiences of iron are especially common on shallow-rooted cool-season grasses (particularly bentgrass and Poa annual) as well as on many of the warm-season grasses. In the mid-west many greens have become considerably higher in pH because of irrigation with hard water. We find pH values of 7.4 to over 8.0 common on greens in Michigan. Lowering soil pH can make the iron more available again. Divot News S.C.G.C.S.A. Once you use a Chipco something.

Hall, Turf Specialist This is a good time of the year to review the characteristics and modes of action of the more popular preemergence turf herbicides. COMMON NAME: TR A D E NAMES: C H EM ICAL NAM E: Benefin Balan, Binnel, Balfin N-butyl-N-ethyl-trifluoro-2, 6-dinitro-p-toluidene Benefin materials are available as emulsifiable concentrates (1.5 lb/gal) and 2.5% granules. Benefin is a volatile material and works best on turf in the granular form. Volatility is reduced when the material is irrigated into the soil soon after application. This material satisfactorily controls crabgrass, goosegrass, pigweed, lambsquarter, purslane, carpetweed, yellow and green foxtail and other turf weeds. Nutsedge, cocklebur, grandsil and ragweed are notably tolerant of benefin. Benefin has a long residual and should not be used in situations where fall overseeding is contemplated. Materials similar to benefin have been shown to inhibit actively dividing cells of germinating seedlings and stop growth processes (3). The material is strongly absorbed through seed coats and the epidermis of shoots. Benefin damages bentgrass and thins fescue but other turfgrasses are considered tolerant (4). COMMON NAME: TRADE NAMES: C H EM ICAL NAME: Betasan Prefar, Pre-San S-(Q O-diisopropyl phosphoro-dithioate) ester of N (2-mercap-toethyl) benzene sulfonamide Bensulide materials are available as emulsifiable concen­ trates (4 lb/gal) and as a 7% granular. Granular materials have provided the best control in Maryland trials. Smooth and hairy crabgrass, goosegrass, foxtail, annual bluegrass, pigweed, purslane and other annual turf weeds are satisfactorily controlled by this material. Six to eight month control may be expected with this material. Effectiveness of this material is hampered by high cation exchange capacity and organic matter content (4). Representatives of this class of compunds are thought to cause alkylation of sulfhydryl groups of proteins, therefore, reducing protein synthesis in roots of germinating seedlings (3). Bensulide has caused injury to bermuda and zoysia. Although the material is safe on bentgrass. It has reportedly increased summer wilting on greens (4). COMMON NAME: TRADE NAMES: CHEM ICALS NAM E: DCPA Phthalic acid, Dacthal, Dacthalor, Oust, DAC 893 Dimethyl tetrachloroterephthalate DCPA materials are available as wettable powders (50 and 75%) and as 2.5 and 5% granules.

CAD-TRETE — Broad spectrum fungicide containing Thiram and Cadmium. spurge, dock, and other tu rf weeds are satisfactorily controlled. Ragweed, smartweed and velvetleaf are notably tolerant of this material (6). Under normal conditions DCPA will persist in the soil for 60 to 90 days (4, 5). The effectiveness of this material is decreased by soils high in organic matter. This class of compounds is not foliar adsorbed nor translocated within the plant. They cause severe stunting of germinating seedlings by arresting cell division (3). DCPA may injure red fescue and bentgrass and its use on golf greens is considered risky. In Maryland tests DCPA decreased the winter survival of sprigged tufcote bermudagrass (1). COMMON NAM E: TRADE NAME: CHEM ICAL NAME: Siduron Tupersan 1-(2-methylcyclohexyl)-3-phenylurea Siduron is available as a 50% wettable powder. Crabgrass, foxtail, cheatgrass, downy brome, witchgrass, purslane, lambsquarter, nimblewill and other turf weeds are controlled. Broadleaved weeds are poorly controlled with this material. Annual bluegrass is very resistant to this compound. Siduron will persist in the soil for 10 to 12 months, but it is the only material that can be utilized in conjunction with bluegrass seeding. The effectiveness of this material is decreased by soils high in organic matter. This class of compounds inhibits photosynthesis leading to closure of the stomata, inhibition of transpiration and eventual death of the germinating seedling (3). Bermudagrass and certain bentgrasses are injured by siduron, whereas, red fescues are considered tolerant. Caution is recommended when utilizing this material on golf greens. COMMON NAME: TRADE NAMES: CHEM ICAL NAME: Tricalcium Arsenate Calcium arsenate, Orthoarsenate, Chip-Cal, Kleen-up Ca3(A s04 ) 2 Calcium arsenate is available as an inorganic material in granular form (48 and 73%) or as an 85% wettable powder. Crabgrass, annual bluegrass, goosegrass, chickweed, and other turf weeds can be controlled with this material. Gradual buildup of toxic arsenic levels in the soil is important in utilizing this material. Many climatic and edaphic factors affect arsenic toxicity and therefore caution must be utilized with this material (2). Arsenates cause death of germinating seedlings by blocking production of high energy phosphate compounds. Red fescues are injured by levels necessary for Poa annua control. With all preemergence materials it is essential that label instructions be closely followed. Water in these chemicals immediately after they are applied and do not disrupt the soil surface.
