Northrup King is a primary distributor of Parade Kentucky Bluegrass, a vigorous, remarkably wear-tolerant variety that provides rapid recovery from damage. So if you’ve got a traffic problem and you ask your Northrup King man what to do about it, he might recommend Parade. On the other hand, he might not. He might recommend another variety — or a blend or a custom blend—that will perform better under your particular circumstances. That’s the beauty of talking with a Northrup King man. He’s not committed to any one approach. He’s committed to finding the best solution to a given problem. If that sounds good to you, write for the name of your Northrup King representative or distributor. He won’t put you on Parade or anything else until he thoroughly understands your problem.

Numerous sugges­ tions to help provide the best golf course at the lowest cost in manpower, natural resources and fiscal expendi­ ture will be shared with participants through education sessions and an industry show. education sessions will feature 38 speakers from universities industry and GCSAA. Presentations will cover Management, Public Golf Owners and Operators, Research, Thinking Superintendent, Turf Manage- ment/North and Turf Management/ South. Areas to be discussed include employee motivation, pesticides on the golf course, legal hiring and firing practices, working with civil service employees, using a stimp meter and common problems with zoning. Seven Besides offering participants a warehouse of knowledge through these sessions, education the conference and show will feature more than 180 exhibitors displaying millions of dollars’ worth of equipment, tools and supplies for turfgrass management. Earl L. Butz, secretary of agri­ culture under Presidents Richard Nixon and Gerald Ford, will deliver the keynote speech, entitled “ I Don’t Want to Live in a No-Growth Society,” at the opening session on Monday morning, February 13. Butz is now the dean emeritus of agriculture at Purdue University. The 39th GCSAA National Golf Tournament will be played at three Corpus Christi, Texas, golf courses on February 9 and 10. The courses are Padre Isles Country Club, Corpus Christi Country Club and Pharaohs Country Club. A victory banquet to honor winners will be held Friday night at the Corpus Christi Country Club. annual GCSAA membership meeting and election of officers will take place Wednesday afternoon in the Convention Center. The A tour of four area golf courses on Friday, February 17, will take some 500 golf course superintendents to Fort Sam Houston Golf Course (Dick Reardon, golf course manager); Oak Hills Country Club (Robert R. Wilson, superintendent); San Antonio Country Club (Roy Schneider, superintendent); and Willow Springs Golf Course (Harold ; A. Henk, superintendent).

ECKHARDT, and GARALD HORST Texas A & M deficiencies are associated with soils having high calcium and magnesium contents. The micronutrient most commonly deficient on turfgrass areas is iron. Deficiencies appear as an interveinal yellowing of the youngest actively growing leaves. Under a continued iron deficiency, the chlorosis spreads to the older leaves and the plants become weakened. An iron deficiency occurs on the youngest leaves while yellowing from a nitrogen deficiency occurs first on the oldest leaves.

Soil applied com­ plete fertilizers with iron and activated sewage sludge materials also contain significant amounts of iron. Reports of problems with foliar burn following applications of water soluble iron as a spray are not uncommon. Thus, this study was initiated during the summer of 1976 the effects of iron rates, carriers, and environmental conditions during application on the proneness to turfgrass phytotoxicity. Four iron sources were utilized in the test; ferrous sulfate, ferrous ammonium sulfate, Chelated 138, and Chelated 330. Rates of application were 0, 4, 8, 12, 16, 20, and 24 oz. of material per 1000 ft2. Applications were made by means of a hand sprayer to four square foot plots. There were three replications tests during 1976 and one test during the 1977 growing season. Visual estimates of to the bentgrass and bermudagrass were taken along with any positive responses the iron application. foliar burn utilized in two to Results. No foliar burn or notice­ able response was observed at the 2 oz. per 1000 ft2 application of iron sulfate to creeping bentgrass. The 4 and 8 oz. rates showed a definite greening response with no foliar burn evident. There was a slight burning at the leaf tips from the 12 oz. rate with the extent of foliar burn becoming greater as the rate of appli­ cation was increased above this level. No burning or greening response was noted from the 2 oz. application Continued on Page 13 anil Hast Wishes far tha lamia Yaar WILKIE TURF Equipment Company 1050 OPDYKE ROAD PO N TIA C , M ICHIGAN 48056 (313) 373-8800 TORO 11 «fe % \ a m (^O S e tf THE HIGHEST CONCENTRATION OF SLOW RELEASING TURF NUTRIENTS IN A SINGLE PRILL 32% NITROGEN PLUS 24% SULFUR = For over ten years research and development has been working on perfecting a form of nitrogen for turf that would: 1.

The 4, 8, and 12 oz. rates produced a signifi­ cant enhancement of green coloration with no foliar burn. However, phy­ totoxicity was evident at application rates of 16 oz. per 1000 ft2 and above at temperatures of 75 to 80 degrees F. At warmer temperatures of 90 to 94 degrees F, foliar burn from ferrous ammonium sulfate was observed at a rate of 10 oz. and above. Chelated 138 caused a distinct reddish coloration which persisted on the leaves and was fairly objection­ able at application rates of 12 oz. per 1000 sq. ft. and above. Chelated 138 did produce a slight greening at the ( 2 oz. rate and substantial enhancement of green coloration at 4 oz./11,000 ft2 and above. Foliar burn was first noticed at the 16 oz. rate of applica­ tion and became progressively more , severe as the rate was increased to 24 oz. Chelated 330 produced a slight to that similar greening at the 2 oz. rate with a major enhancement of green color at higher rates reported for Chelated 138. However, a slight foliar burn was evident at the 6 through 14 oz. rates. Objectionable degrees of foliar burn were evident at rates of 14 oz. per 1000 ft2 and above. from that Summary. R e s u l t s indicate these foliar investigations burn is occurring at relatively high application rates compared to those commonly in use. Frequent reports of foliar burn at substantially lower rates, suggest that the iron is being applied with the other chemicals, which in combination, are causing foliar burn. The rate of application at which foliar burn occurred did vary among the four materials and increased as tempera­ tures increased. However, with temperatures up to 95 degrees F. on a creeping bentgrass turf, iron applica­ tions can be made in the range of 4 to 8 oz. per 1000 square feet without concern for foliar burn. Complete!

MCAFEE Soil pH (soil reaction) to describe is a term used the acidity or al­ kalinity of a soil. A pH of 7.0 is neutral, while anything below 7.0 is acid and anything above 7.0 is con­ sidered alkaline. Most turfgrasses grow best at a slightly acid pH (6.2 - 6.5). As soil pH deviates from this range, many of the plant nutrients in the less available for plant growth. Therefore, maintaining the soil at the proper pH range is very helpful in the maintenance of quality turfgrass. Also, soil pH the efficiency of applied decreases fertilizers, thus increasing the cost of turfgrass maintenance. soil become improper the Soils with a low pH can be cor­ rected by the addition of limestone, while soils with a high pH must be corrected by the addition of some type of acidifying material such as sulfuric acid, acidifying fertilizers (ammonium sulfate, ammonium nitrate, etc.) or sulfur. Rates of lime needed to correct acid soils have been established. However, rates and types of acidifying material needed to correct alkaline soils are not fully understood at this time. Research is currently being conducted by several investigators to establish the best materials, rates, timing of application to correct and high pH soils. Sulfuric acid will react the fastest to correct a high pH. However, it is too dangerous and corrosive to be used in most turf situations. One of the best materials for correcting high pH soils is sulfur. Micro­ organisms the soil convert the elemental sulfur to sulfuric acid. It is for this conversion that creates the acidity. Sulfur comes in three forms; (a) powder, the oxidation process elemental in SEASON'S GREETINGS! ¿¿¿¿S ü Write or call direct E N G IN E E R E D R A IN Sprinkler Irrigation Supply Co.
