FROM THE PRESIDENT'S

DESK

Dick DeSplinter

Over the course of the golf season the superintendent is faced with many pro-blems. One problem I'm experiencing this spring is severe com-

paction. More severe than most fall com-paction problems. There are many contri-buting factors. Lack of moisture, low humidity, heat and heavy spring play are a few examples. To alleviate the pro-blem, aerification seems inevitable. Most seasons the superintendent can get by quite nicely by slicing the green weekly. Not true this season; at least not at my course. "Caution", over water-ing or saturating the greens will only add to the compaction problem.

Also very important is to eliminate the compaction without interrupting play. I believe the only answer is to aerify with small tynes, remove plugs and re-cut the green as quickly as possible. With some of the equipment available to-day, this can be accomplished in 20 min. per green with two men and two machines.

The entire membership thanks host super-intendent, Dick Toupal and host prof-essional , Ray Vennewitz for the splendid day of golf last month. North Oaks was in terrific shape and we all enjoyed every stroke. Some took so many strokes, they ended up over-joyed!

Congratulations to Mike Klatte of Elm Creek. His April article, "Automatic Irrigation for Disease Control", will be reprinted in the Carolinas

National Exhibition Preparations BY NICK DUNN, SUPERINTENDENT

HAZELTINE NATIONAL GOLF CLUB

On July 1, 1980 a special P.G.A. event w i l l be held at Hazeltine National Golf Club. The Grand Slam of Golf i s a one day exh ib i t ion match between four of the top ranking champions to benefit the P.G.A. Junior Golf Foundation. The day s ta r t s with the 1979 champions of the

P.G.A., U.S. Open, Tournament Players 1 Championship and the Masters presenting a one hour c l i n i c and shot making demonstration at 11:00 a.m.

At 1:30 p.m. David Graham, Lanny Wadkins, Hale Irwin and Fuzzy Zoel ler tee i t up for 18-Holes of head to head excitement for the spectators.

Following the day of go l f a dinner w i l l be held at the Carlton Celebrity Room where many outstanding ce lebr i t ie s w i l l be in attendance. Dinner t icket holders wi l l have the op-portunity to v i s i t with the supporters of Junior Golf including the day ' s p layers.

The P.G.A. created the Junior Golf Foundation to support a program to help juniors develop their s k i l l s and knowledge of the game. A l l t ickets for the go l f event and the dinner are tax deductible with a l l proceeds going to the Junior Golf Foundation.

The go l f course wi l l be set up as i f the club were hosting a national championship. We met with the P.G.A. o f f i c i a l s l a s t f a l l and discussed the course set up and reviewed the P.G.A. Tournament Manual. The course w i l l be completely roped tee to green. The fol lowing cutt ing spec i f i cat ions have been set up: Greens wi l l be cut at 3/16 inch or l e s s ; a 30 inch co l l a r around the putting surface wi l l be maintained at 3/8 inch; tees wi l l be cut at 1/2 inch or l e s s . An intermediate rough 6 to 10 feet wide w i l l be cut around the entire fairway and green at 1 1/2 inch. The fairway wi l l be at 1/2 inch. Al l rough except for the intermediate rough wi l l be at 5 to 6 inches. Al l cutt ing spec i f i cat ions are currently being followed except for the 5 to 6 inch rough. The P.G.A. i s allowing us to maintain a 3 inch rough unti l one to two weeks pr ior to the event, depending on weather, and then discontinue cutt ing to achieve the deep rough desired. You can imagine the questions and complaints about rough depth that I am receiv ing.

Hosting th i s event i s not a great problem but when you consider the winter we have ex-perienced, the areas of no tu r f cover and the construction that was started l a s t f a l l and i s yet to be completed before the event, my s t a f f and I have been kept very busy.

As of May 20 we were ju s t completing the sodding of the 18th Fairway and s t i l l had 10,000 square yards of bluegrass sod to lay in rough areas and around eight newly constructed fairway bunkers.

Needless to say, the rest of the go l f course has suffered some in general maintenance in our attempt to use a l l of the dry weather working on course construction. Hopefully, we can pull i t a l l together pr ior to the deadline of July 1.

Following the exhib i t ion on July 1 the l a s t phase of the Hazeltine reconstruction program wi l l begin. The 16-Hole, now a Par 3, w i l l be changed to a 390 yard Par 4. Tees have already been constructed below the 15th Green on the shore of Lake Hazel-t ine. The tee shot wi l l have to carry 210 yards of open water to a narrow fairway with the lake on the r ight and a creek on the l e f t . From there the hole wi l l bend s l i g h t l y r i ght where a new green wi l l be constructed to the r ight rear of the present green out into the lake at the level of the water. The 17-Hole wi l l then become a Par 3 with a new tee being bu i l t about 180 yards from the present green. Both holes should be in play in the spr ing of 1981.

The days when turf just laid around looking pretty are long gone. Now your turf has to be pretty—and pretty tough, too. Tough enough to take all kinds of wear and still go on looking terrific.

That's just why so many pros like you specify turf seed from Northrup King. For years, Northrup King has given pros all they need—low mainte-nance varieties, winter hardy blends, special mixes for specific geographic problems, and expert help in selecting the right one.

And no matter what Northrup King turf seed the pros use, they get turf that's good looking and hard working.

Conserving Energy With Plants A well designed tree t ransp lant ing program can do a great deal to add character to a go l f course. Properly placed, trees and shrubs can d i rect t r a f f i c f low, in su late the course from surrounding homes, and provide eye-pleas ing v i s t a s , not to mention welcome shade for weary g o l f e r s .

However, a good p lant ing program should not stop with the go l f course. Trees and shrubs placed s t r a t e g i c a l l y around course bu i ld ing s such as the clubhouse and maintenance shed not only make these areas more a t t r a c t i ve , they a l so can r e su l t in a considerable energy sav ings .

Writing Effective Reports

As an executive in what i s , a f te r a l l , a business o rgan i -za t i on , you may be ca l led upon to write per iodic reports on your operation or current and future project s . The art of wr i t i ng c lear and e f fect i ve re-ports i s one each executive should master. Here are some th ings to keep in mind as you wr i te:

Remember your reader. General ly, reports are written for one spec i f i c person, such as the green chairman, general manager or other club o f f i c i a l . Write as though you were speaking to that person, keeping in mind h i s l i ke s and d i s l i k e s .

Organize your report. Don ' t make the reader have to dig for the important po in t s . State your case in 1 -2 -3 -o rder , with headings, i f poss ib le to br ing out important f ac t s .

Make i t object ive. Don ' t spend so much time t e l l i n g how you feel and what you think that the reader misses the f a c t s . Avoid exaggerat ion, extravagant statements and gene ra l i t i e s .

Get to the point. Ed i t out every-thing which does not serve some informative purpose in your re-port and t e l l your reader im-mediately what he needs to know. Then f i l l in the d e t a i l s .

Document your report by attach-ing copies of c l i p p i n g s , l e t te r s or price schedules that support your conc lus ions .

Develop a wr i t i ng s t y le that i s i n te re s t i ng and e a s i l y read. Keep your paragraphs short and avoid long and involved sentence s t ructure . Indent or underscore important points to make them stand out.

ALL ABOUT SPRAYERS BY 0. W. "RED" KROMER

A sprayer for application of chemicals i s one of the most essential machines for golf course maintenance. Many courses have two or three sprayers, using one exclusively for herbicides and another for fungicides. This means, each sprayer i s supplied with the proper nozzles and cal ibrated to apply the correct amounts of spray mixtures. I f i t i s not economically feasible to own two or three machines, then one good commercial type sprayer should be obtained and be adaptable for both hi and low pressures.

Chemical weed control requires exact amounts of chemical, uniformly applied. At f i r s t i t may seem complicated to apply a spec i f ic amount of chemical per 1000 sq. f t . However, i t i s quite simple i f taken a step at a time. The components of a sprayer and their functions should be thoroughly understood, as well as the var iables, which must be controlled to give an accurate spray appl ication.

F i r s t , the sprayer. The tanks should be corrosion res i s tant , have a large f i l l e r opening for cleaning and have jet or mechanical ag i tator. The pump can be low pressure - r o l l e r , gear, rubber impeller, centrifugal or turbine - with a capacity in gallons per minute at least 50 percent greater than the nozzle and jet agitator requirement ( i f a jet agitator i s used). This allows for pump and nozzle wear. The ideal machine would have a multiple piston pump with a mechanical ag i tator. A piston pump machine can be used for hi«pres-sure machinery cleaning, ta l l tree spraying or f i r e f ight ing and i s eas i ly repaired when worn. A sprayer should have an accurate gauge, preferably brass, glycerin f i l l e d with not over 100 p . s . i . ca l ibrat ion for accuracy around 30 to 60 lbs . - the low pressure spraying range. I f the machine i s also a hi-pressure unit , the low pressure gauge^can be replaced with a hi-pressure gauge or a valve in s ta l led below the gauge to shut i t off for hi-pressure spraying.

The pressure regulator should have su f f i c ient capacity so that low pressure can be ob-tained and be sens i t ive so i t controls the pressure accurately. A dual low and h i -pres-sure system can be in s ta l led on a hi-pressure sprayer, allowing the low pressure regu-lator and gauge to be used for boom spraying. When the boom is shut o f f , the h i -pres-sure system with i t s regulator and gauge can be used for hand spray gun work. With a dual system, the hi-pressure regulator should be made so i t can be tr iggered to rel ieve the hi-pressure for low pressure work.

Nozzles must be chosen for s i ze , from the nozzle chart, to give the gallonage rate de-s i red at the recommended pressure and travel speed. Most nozzles are rated at 30 p . s . i . and 4 m.p.h. and 20" spacing. A 20" nozzle spacing i s preferred over 10" spacing because

i t has a larger o r i f i c e , therefore, i t i s more d i f f i c u l t to clog. Also i t i s more accurate and produces larger droplets for herbicide work-larger droplets give better weed k i l l and are less affected by wind. The matching screen can have coarser mesh allowing fine part ic les to pass thru the screen and nozzle. The deflector or f lood-ing type nozzle, as i t i s cal led (a mis-nomer), i s preferred because i t has a cy l indr ica l o r i f i c e , which retains i t s accuracy at least ten times the l i f e of the or ig inal fan type nozzle. In addition to t h i s , i t continues to spray a broad fan throughout i t s useful l i f e , where with the

continued on Page 8

conventional fan nozzle, the spray pattern gets narrower and narrower as the discharge o r i f i c e wears, f i n a l l y shooting a s o l i d stream of much greater volume.

The deflector type has the added advantage of producing larger droplets, which produce better weed k i l l (by Univers i ty test ) and are less affected by wind.

The boom we prefer i s a smooth, s ta in le s s tube of su f f i c i en t s ize - 3/4" I .D. or larger -so the end nozzles receive the same pressure as the one near the feed hose. I t i s also preferable i f the nozzles come out of the side of the boom instead of the bottom, as th i s allows d i r t par t ic les and precipitated chemical, by passed by the main screen, to sett le to the bottom of the boom rather than going r ight into the no7zle screen.

Traditions Are Important At Baltusrol Baltusrol Golf Club in Sp r i ng f i e ld , N. J . , s i t e of the 1980 U.S. Open, i s steeped in h i s tory and has hosted more championships of the United States Golf Associat ion than any other club. The 1980 Open marks the s i x th time the prest ig ious event has been contested at Ba l tus ro l .

Add i t iona l l y , three U.S. Amateur Championships, two Women Open have been played on outstanding Baltusrol courses.

's Championships and one Women's

L i t t l e wonder, then, that there i s t rad i t ion in the background of the Golf Course Super-intendent, Joseph R. Flaherty, CGCS. Flaherty grew up in the area. His father was super-intendent of Manasquan River Golf Club, B r i e l l e , N. J. for more than 30 years pr ior to his death in 1973. B a l t u s r o l ' s long time Golf Course Superintendent, Ed Casey, hired Flaherty as an a s s i s tan t in 1964 r i ght after he had received his B.S. degree in plant science from nearby Rutgers Un ivers i ty . When Casey ret i red on January 1, 1963, Flaherty was promoted to the pos i t ion of Golf Course Superintendent.

While there have been no U.S.G.A. championships at Baltusrol since 1967, maintaining the course to championship standards i s not new to Flaherty. That i s ju s t another Baltusrol t rad i t i on . Club members expect championship condit ions at a l l times. They are proud of the reputation which the Club has received from hosting so many U.S.G.A. championships.

"We are not doing anything d i f fe rent l y to prepare for the Open," says Flaherty. "Our members and I want the course to be in peak condit ion for the Open. I f the weather con-tinues to cooperate, we are sure Baltusrol wi l l l i ve up to i t s reputation as a f a i r but challenging test of g o l f . " The only changes in regular maintenance

procedures for the Open wi l l be double-cutt ing of the greens. B a l t u s r o l ' s greens are regular ly cut at 3/16" and fairways at 5/8" heights, and that i s about what they wi l l be during the Open. Double-cutting immediately pr ior to and during the Open wi l l assure the fast but true greens that are a trademark of USGA competitions. The large greens have subtle contours and three putts wi l l not be uncommon.

Baltusrol i s located jus t 22 miles from New York City and but minutes away from U.S.G.A. headquarters, Golf House, in Far H i l l s , N. J. I t has an Upper Course and a Lower Course and both are con-sidered excellent enough for U.S.G.A. championship standards, a rare tr ibute to the club. To many, they represent the ultimate of the many outstanding courses designed by the renowned go l f course arch i tect , A. W. T i l l i n gha s t . The Lower Course, which stretches 7,000 yards through heavily wooded te r ra in , w i l l provide the test for the 1980 Open as i t did in 1954 and 1967, and for the Women's Open in 1961. Robert Trent Jones redesigned several holes on the Lower Course in preparation for the 1954 Open.

The course w i l l be much the same as when Jack Nicklaus set the U.S. Open scor ing record of 275 in Ba l tusro l in 1967. His c l o s i ng 65 i s considered one of the great rounds in Open h i s t o r y . Several championship tees have been enlarged, but players w i l l not notice any great d i f ference. "About the only change go l fer s w i l l notice w i l l be the practice area.

The Golf Course Superintendents As soc iat ion of America i s another t r ad i t i on important to F laherty. His father was a long-time member of the As soc ia t ion . Ed Casey, a former national d i r ec to r , has been a G.C.S.A.A. member for nearly 40 years . B a l t u s r o l ' s Super-intendent himself jo ined G.C.S.A.A. in 1965, achieved Class A status in 1971 a f ter serv -ing as Golf Course Superintendent the required three year s , and became a Ce r t i f i ed Golf Course Superintendent in 1975.

In order to become c e r t i f i e d , Flaherty had to pass a r igorous s i x -hour exam tes t ing h is knowledge of the rules of g o l f , pract ica l tu r f management, and the h i s t o r y , purposes and procedures of G.C.S.A.A. and h i s p rofess ion.

HOW TO REPAIR BALL MARKS

THE TROUBLE WITH BALL MARKS: The bal l landed with a thud. The green was so f t and as the ball bounced forward i t l e f t a deep l i t t l e crater in the tu r f exposing brown earth at the back and grass blades pushed together at the f ront . Ignor ing the l i t t l e c ra te r , the go l fe r walked up to h i s b a l l , cleaned i t , holed h i s putt and glowed with s e l f -s a t i s f a c t i o n . Some hours l a te r af ter the exposed earth in the bal l mark had dr ied out, another go l fe r found the damaged area in h i s l i ne of putt. He attempted repa i r s , but the re su l t was not very s a t i s f a c t o r y . An unflattened b i t of t u r f twisted h i s putt o f f l i n e . Next morning an i n -experienced greenkeeper mowed the putt ing surface without repa i r ing bal l marks. The re su l t was a putt ing surface pocked-marked, untrue and covered with bare spots where the mower scalped the grass from the t u r f . WHAT HAPPENS: What actua l l y happens when a bal l mark i s not promptly and properly repaired? 1) So i l i s exposed and so the area immediately surrounding the bal l dr ies up fa s te r than i t would i f the bal l marks were repaired; and thus a blemish i s l e f t on the green. 2) There i s a chance that the ra i sed t u r f caused by the bal l w i l l dry qu ick ly and may die out. 3) The open s o i l i n v i t e s weed invas ion, such as crabgrass , s i l v e r crabgrass , P0A ANNUA, dandelion, p lanta in or Pearlwort..seed of which could be brought in on the shoes of g o l f e r s , caddies or workers or on mowing equipment. 4) The improperly repaired or neglected bal l marks leaves a bumpy spot in the green. I f not corrected before cutt ing the next day, then the spot i s scalped by the mower and the bruise mark remains for several days.
