reetings from upper East Tennessee! As we enter the winter months and hopefully enjoy a break from the “in season” rigors of the job, it is time to think about continuing education. Therefore, mark your 2007 calendar for the Tennessee Turfgrass Conference and Trade Show, to be held on January 14-16 in Franklin, Tennessee. In my opinion, there is no better place to hear great speakers and to network with fellow turfgrass professionals, as well as receive continuing education credits and pesticide re-certification points. The 2007 event looks to be one of the best ever, as Dr. Tom Samples and the TTA Education Committee have filled the program’s slate with a fabulous host of speakers and topics. With an exciting change of venue this year, we are anticipating a great turnout at the Marriott Cool Springs in Franklin. Therefore, I

encourage anyone who is planning to attend to register soon. Don’t forget to bring your assistant and/or other key personnel, as this is a great opportunity for them to also further their education. For those who will need overnight accommodations, please make your room reservations through Marriott to ensure you receive the special TTA Conference rate. On behalf of the TTA, I would like to wish you and yours a safe and happy holiday season and a great 2007. I look forward to seeing you in Franklin! T

on’t look now, but there goes another year. Boom… just like that… gone. I know we all got everything done we wanted to do, right? Perfectly, just like we planned it, all without a hitch. Our sports fields are showplaces, we’re a shoe-in for our local “yard of the year” award, our kids did chores and homework without being asked, and our spouses just could not be happier with us. The entirety of our professional and personal goals, dreams and aspirations for the year were met. No doubt about it — you’re a peach. Where’s the fun in that? Effective managers in general like to be challenged, but good sports turf managers thrive on it. Come on — admit it. Somewhere deep down, you dare Mother Nature and the “mortal powers that be” to come with their best. Bring on dallisgrass, nutsedge and any turf-devouring vermin. Bring on the stupidest idea anyone ever had for an event to be held on your field. No matter — you’ll take ’em deep. You’ll pull it off in grand fashion. So here’s to you, ‘O Guru of the Grass and Doctor of the Dirt. It’s what makes you special and creates the bond between you and your brethren. I hope everyone’s year was successful and rewarding. The TVSTMA started the year with some goals, and we did a pretty good job achieving them. Meeting attendance was up from last year, and our website is back and updated. Although we gained some new members, membership growth and active membership remain, in my opinion, areas for improvement. We especially have tremendous potential to make an impact within the parks and recreation ranks, as well as the prep ranks. I know I’m preaching to the choir again, but please bring your ideas to the Tennessee Turfgrass Association’s Annual Conference & Trade Show in January. The TVSTMA meets during the Conference. This is when we raise our sail and set our course for another year. It provides the opportunity to openly express our views, elect our leadership and conduct our business in the proper quorum — freely and without

reservation — in a positive and professional manner. The conference is January 14-16. If you could attend only one conference per year as a sports turf professional in our part of the world, this is the one. Thanks to all who served as hosts, speakers, sponsors and organizers to make our 2006 Field Days successful. Special thanks to those who gave of themselves in their leadership roles and who understand the importance of responsible performance of duties to our chapter. Time is our most precious commodity, and your generosity made our meetings time well spent. Finally, I offer my sincerest thanks to you for allowing me to serve my friends, the members of the Tennessee Valley Chapter of the Sports Turf Managers Association. T Al Ray TVSTMA President

TENNESSEE TURFGRASS DECEMBER/JANUARY 2007

T

urfgrass is a biological system, subject to weather stresses and pest challenges, so you must always be prepared that the loss of a turfgrass stand is just around the corner. Knowing the necessary steps to establish and renovate turf can save you time and money as you bring a site back to life. Poor soil conditions, pest damage, excessive thatch and improper management are four factors contributing to poor turfgrass stands. Even so, in many cases, properly implementing the five primary cultural practices — mowing, fertility, pest management, cultivation and irrigation — is not enough to sustain or regenerate turfgrass. Therefore, re-establishment or renovation of turf is eventually necessary. The location and function of a turf area are also important. A turf stand that is adequate for a home lawn typically won’t hold up to the rigorous demands of an athletic field or golf course. Therefore, decisions to re-establish or renovate turf will not be the same. For instance, a soil-layering problem that contributes to shallow rooting typically leads to signs of turfgrass stress and decline during hot, dry periods. On an athletic field, addressing such a problem is vital because traffic causes compaction and a shallow turfgrass-root system. Turfgrass growing under these conditions becomes stressed, and the condition is compounded as game traffic continues. However, on a home lawn, the turf’s stressed condition is evident only during hot and dry periods, which may be for only a couple of weeks in summer. Thus, the need to renovate or re-establish the home lawn is not as critical. TENNESSEE TURFGRASS ASSOCIATION • TENNESSEE VALLEY SPORTS TURF MANAGERS ASSOCIATION

COVER STORY 5. Basic fertilizing 6. Amending and modifying the soil 7. Performing finish grading 8. Applying starter fertilizer 9. Planting 10. Mulching when seeding Depending on the condition of the turf, one or all of these steps may be necessary, but the order is critical for success.

1. Soil sampling and testing Soil sampling is necessary to assess the site’s requirements for lime and fertilizer. Most basic soil-test reports indicate pH, phosphorous and potassium contents. In areas where soil compaction is a significant problem, you should also request a separate soil-particle-size analysis. If you modify the topsoil in any way during establishment, test a second soil sample to ensure you’ve modified it properly. Soil sampling especially benefits home lawns because, quite often, the soil around a home’s foundation is actually subsoil from the hole dug for the basement. Typically, subsoil has a finer texture and is poorer quality than is necessary for a strong, healthy turf. How do you assess an unacceptable turfgrass stand to determine whether to re-establish or renovate? For a home lawn, at least, the typical rule of thumb is to re-establish a lawn if more than 50 percent of the area is comprised of weeds or has poor turf. If turf covers more than 50 percent of the lawn, then you renovate, instead. It is sometimes difficult to totally separate re-establishment from renovation because the two tasks involve the same processes. For the purpose of this article, we’ll define re-establishment as the complete removal of existing turfgrass, followed by the establishment of a new stand by seeding, sodding, sprigging or plugging. Renovation means simply replanting new turfgrass into the existing turfgrass stand. Many re-establishment projects begin as simple renovations. However, as the job unfolds, learning the cause of the troubles may lead to the need for a major overhaul. Always, you must correct the cause of the poor turf stand before you repair the areas, or you’ll be doomed to repeat the process.

When re-establishing a site You can effectively manage turf with proper planning and site preparation during re-establishment. Whether you seed, sod, sprig or plug, you should follow ten steps to establish a new turfgrass area: 1. Soil sampling and testing 2. Controlling persistent weeds 3. Rough grading 4. Liming 20

TENNESSEE TURFGRASS DECEMBER/JANUARY 2007

2. Controlling persistent weeds The presence of perennial grasses and broadleaf weeds will present future problems if you don’t attend to them before establishment. Fumigants (methyl bromide), soil sterilants (dazomet) and non-selective herbicides (glyphosate and glufosinate) are the most effective means of pre-planting weed control. They also are the only means of controlling perennial grassy weeds in your turf. Identifying weeds as annual or perennial will aid you in deciding how to control them. Their identification is also critical in determining whether to renovate or totally re-establish a site.

3. Rough grading Rough grading consists of removing debris, grading the site’s general slope and adding any necessary topsoil. In many instances of re-establishment, you don’t need to rough grade because the builder did it during construction and initial turf establishment. However, the builder may have also buried materials such as large rocks, wood or stumps just under the site’s surface. These objects can eventually make their way back to the soil’s surface and cause problems. You’ll therefore have to remove them if they have presented a problem in the past. In situations where drainage is the cause for a poor turf area, you’ll need to establish a slope to add surface drainage. Since a one-percent crown on athletic fields is often enough slope for surface drainage, this is a good minimum to keep in mind

COVER STORY

for home lawns as well. The slope away from buildings should never exceed 25 percent because it is difficult to maintain and irrigate steeper slopes. In any case, it is important to ensure that the slope is continuous and that no areas are present where standing water can collect.

4. Liming Proper soil pH is essential for nutrient availability to turfgrass. Liming is necessary only when soil tests indicate that your soil is acidic (with a pH below 6.0). In this case, you’ll need to bring it to the proper pH level (6.0 to 7.0). If you need to lime the site, be sure to apply it a minimum of three weeks before you apply starter fertilizer so that the lime does not inhibit the effectiveness of fertilizer nutrients intended for the germination process. Apply lime according to recommendations from your soil-test report.

7. Performing finish grading

5. Basic fertilizing Phosphate (P) and potash (K) are termed “basic fertilizer nutrients.” You should apply them in accordance with soil-test recommendations (according to Step 1). Till in the basic fertilizer to a depth of 4” to 6”. Because these basic nutrients do not readily move through soil when applied to established turf, it’s important to incorporate them into topsoil before seeding.

6. Amending and modifying the soil You can improve soil that has low organic matter or poor soil texture (which can lead to poor water infiltration, water 22

TENNESSEE TURFGRASS DECEMBER/JANUARY 2007

retention or compaction) by amending or modifying it. Amending and modifying soil is an easier step than substituting new soil, which is a major task. Many turf managers use reed sedge and sphagnum peat mosses as soil amendments. If you decide to add sand to improve soil texture in a poorly drained area, you must add more than 60 percent of a properly selected sand before infiltration will improve. Adding any amount less than 60 percent (of the total soil composition) is typically ineffective. In addition, if you select the wrong size or type of sand particle, you can worsen the situation. Finally, you must thoroughly mix the sand into the soil to avoid layering. Because soil modification is a difficult process, you may want to hire a soil consultant to determine if soil modification is warranted and the appropriate solution to your soil problem.

The finish grade is the final preparation step for the seedbed or planting surface. Smooth the surface with a yard rake, and lightly roll the area to smooth any depressions. You may need to perform repeated raking, leveling and settling (using water) to avoid depressions that allow water to pond. This step is the cheapest way to ensure that water drains away from buildings or other undesirable areas.

8. Adding starter fertilizer Think of starter fertilizer as a nutrient source for the turf to

Email TTA at: tnturfgrassassn@aol.com


CONTINUED use immediately after germination. You can combine this step with finish grading if your turf area is large. A starter fertilizer should consist of a 1:2:1 ratio of N-P-K. The high P aids in seedling establishment or root promotion of harvested sod. Base the rate on pounds of N per 1,000 square feet, and apply it at 0.5 to 1 pound N per 1,000 square feet.

9. Planting Before you decide whether to seed, sprig, plug or sod in an area, you must select the proper turf species. The species must be adapted to the area, or else it won’t thrive. It is also critical that you purchase high-quality seed that is free of weed seed. Consult with your county or state extension offices to find out the best varieties for your area. When establishing turfgrass by seed, the method and timing of seed application are as important as appropriate seed selection. You should plant turfgrass seed when growing conditions are most favorable for the desired species. For example, establish cool-season species in late summer or early fall, and establish warm-season species in late spring or early summer. To ensure a uniform coverage, apply the seed in two directions. After seeding, lightly rake the soil surface with a leaf rake and then roll the establishment site, to ensure seed-to-soil contact. For cool-season turfgrass seeding, apply Quinclorac herbicide at 1 lb./a before or 28 days after the emergence of tall fescue or Kentucky bluegrass, for annual grass-weed control. Sodding is a more rapid method of establishment than seeding, but it is also more expensive (usually by about 50 percent). Select sod that is free of weeds and weedy grasses (such as crabgrass, dallisgrass and non-desirable turfgrasses) and that contains the species and cultivar(s) recommended for your location. It is important to select sod that has been grown on a soil type that matches the site where you will lay it, particularly if your site will experience traffic. Washed sod or soil-less sod grown on plastic is an alternative sodding method that prevents potential soil-layering problems. It is even more expensive, however, than conventional sod — about two to five times greater in cost. You can lay sod nearly any time of year if the soil is dry enough to allow preparation and if environmental conditions are favorable (offering adequate

light, temperature and water). Sprigging is the process where the stolons and rhizomes of warm-season grasses are harvested and used to grow-in turfgrasses such as bermudagrass. Sprigging is cheaper than sodding and is done for species where seed is not viable. Plugging is space-planting whole plugs of warm-season turfgrasses (such as bermudagrass, zoysiagrass and St. Augustinegrass) and allowing them to fill in over time.

COVER STORY Bermudagrass and St. Augustinegrass plugs can be planted 12” to 18” apart, and zoysiagrass plugs can be planted 6” to 12” apart. Plugs are cheaper than sod, but the planting process is much more time-consuming and, therefore, may cost more if you are contracting the work. When sprigging or plugging, it is best to apply a pre-emergent herbicide (such as oxadiazon) to reduce crabgrass and goosegrass competition.

10. Mulching when seeding If you seed your site, then mulching is the final step to ensure uniform germination and establishment. Mulching helps control erosion and seed movement, and it helps retain moisture. Avoid mulching with materials (such as sawdust) that compete with seedlings for nutrients. Paper mulches and straw are good choices, but straw needs to be weed-free. The critical follow-up step, of course, is irrigation, regardless of whether you sod or seed the site. Make sure that the soil remains moist until a new root system develops. Basically, this means irrigating about 1/4” per

26

TENNESSEE TURFGRASS DECEMBER/JANUARY 2007

day for the first week after installation. After a sufficient root system develops, reduce irrigation frequency and irrigate to a depth of 4” to 6” every 5 to 10 days.

When renovation is the proper technique… How do you decide whether to renovate a turf area or re-establish it? To answer this, you must determine the severity of the problem that is causing turf decline. In many instances, it is not necessary to completely re-establish a poor turf area. Therefore, renovating the area is more cost-effective and less time-consuming. Nevertheless, when renovating a turf area, just as with re-establishment, you must determine and correct the cause of poor turf before you replant. You’ll know to renovate when you can’t improve turf performance through one or all of the five primary cultural practices — mowing, fertilizing, managing pests, irrigating and cultivating. Too much or too little of any of them may have caused the poor turf stand simply by making it more susceptible to disease, insect damage or weed encroachment. For instance, mowing too short causes stressed turf, which in

Email TTA at: tnturfgrassassn@aol.com


CONTINUED turn makes it more susceptible to pest damage and turf decline. After you’ve identified the cause(s) of turf problems, you’ll need to prepare the site before replanting. You must eliminate undesirable weeds and insects to achieve and maintain a desirable turf stand. Cultivation (aerifying) is another practice that can alleviate many problems associated with poor turf, sometimes allowing you to renovate rather than totally re-establish a site. For example, core-aerating or spiking can improve soil-layering problems. Verticutting, core-aerating and slicing also help modify thatch layers that cause poor turf. You’ll also want to scalp the turf by setting your mower low, then either verticut, slice or spike the turf to set the stage for good seed-to-soil contact when you seed. If you verticut, be sure to rake up any debris before seeding. Take soil tests to determine if any nutrient deficiencies exist or if your site needs liming. Finally, apply a starter fertilizer before seeding. To replant, spread the seed with a drop or broadcast spreader, and then go over the area with a drag mat, brush or rake to achieve proper seed-to-soil contact. Slit-seeding is another effective method for replanting because it ensures good seed-to-soil contact. Again, which-ever method you use, you should seed in two directions to ensure uniform coverage. As mentioned previously in the re-establishment sections, irrigation is the final key to ensuring healthy turf success. Follow the steps described above for renovation, just as for re-establishment. We can’t overemphasize the importance of implementing the five primary cultural practices. Properly performing each provides the most favorable growing conditions for desired turfgrass species to help your site achieve and maintain a healthy turf stand. T

TENNESSEE TURFGRASS DECEMBER/JANUARY 2007

CONTINUED

Of

the 16 essential nutrients needed by turfgrasses, nitrogen (N) is required in the greatest quantity, promoting visual quality, damage recovery and vigor. Because most soils supply insufficient amounts of N to support quality turf, nitrogen-containing fertilizers must be applied throughout the growing season. Soil N is continually changing form, from organic N to ammonium, then on to nitrate and possibly back to organic N. It can also exit the turfgrass system as a gas or in clippings, and through runoff and leaching. Of these, nitrate leaching is usually considered as the greatest environmental threat. Most research conducted over the last three decades describes a fairly low potential for nitrate leaching from properly managed turf. There are, of course, always exceptions, such as when bermudagrass is fertilized during the winter or when excessive irrigation is applied. One of the shortcomings with much of the scientific research, however, is that most has been conducted on relative small plots of carefully managed turf. This may not adequately reflect the real world, where soil processes (such as nitrate leaching) occur on a much larger scale. Ecological studies at this larger, “landscape” scale are more difficult, more expensive and often more timeconsuming, which is why only a handful of such projects have been conducted on turfgrass systems (and mostly on cool-season turf). Because of continuing concern about nitrate leaching, and to fill in the gap for warm-season turf, we undertook a multi-year, landscape-scale study to evaluate nitrate dynamics on two golf courses located in the coastal plain of North Carolina. We designed this study to answer several questions regarding nitrate concentrations and movement under bermudagrass: • Are soil and groundwater nitrate concentrations dependent on location (comparing fairway, rough and unfertilized out-of-play areas)? • Do nitrate concentrations vary by season? • Is there evidence that nitrate moves towards, and ultimately contaminates, adjacent surface waters? • Do normal golf-course fertilizer practices represent a threat to surface waters and groundwater?

TURF TALK Our research

On both golf courses in our recent research, several holes were chosen for study, each adjacent to a stream (or pond). Surface contours sloped towards the water, suggesting that the shallow water table under each fairway flowed to and drained into the stream. Two types of sampling devices were installed at intervals across each golf hole so that the fairway, the rough on each side of the fairway and out-of-play areas (buffers) adjacent to the rough were included (see Figure 1). The first device, called a lysimeter, extracts the soil solution directly from the rootzone. We could then measure the nitrate concentration that the roots are “seeing,” and we could follow changes with soil depth and over time. The second device is a shallow well, from which we obtained samples of the groundwater for analysis. As it turned out, the groundwater under the fairways was in direct contact with, and fed into, the streams. Thus, the nitrate in the groundwater was very important since it also was feeding into the stream. If there were high nitrate levels in the groundwater, this could ultimately cause contamination of the stream. Conversely, if the levels were low, it would indicate that the golf course posed little threat to

CONTINUED the stream. We also sampled the streams at two locations, the first just before the streams entered the golf course and the second just as they left the golf course. Samples were taken numerous times during the seasons and analyzed for nitrate. We were interested in comparing the two locations, since higher concentrations at the outflow would indicate nitrate contamination originating from the golf course. On the other hand, if the two locations had similar nitrate levels, it would mean the golf course was not damaging the water quality in the stream.

Our results

The results from our study are encouraging. We found consistent patterns for nitrate within the rootzone at both golf courses, with higher concentrations in the fairway and rough and very low concentrations in the unfertilized non-play areas. This is important, as it indicates that the strategy of maintaining a buffer next to the streams reduces nitrate loading at a very sensitive location in the ecosystem. Although the average levels in the fairway and rough were higher than in the buffers, they are still fairly low compared to most agricultural cropping systems. Over the seasons, we also observed

too surprising. And it seems somewhat ironic that overseeding, an often unpopular chore, might actually have some environmental benefit. Data from the shallow wells reflected the nitrate profile found in the rootzone, with higher concentrations under the fairway and low (often very low) concentrations in the lower non-play area. Again, this indicates that the non-play area was working effectively as a buffer to keep nitrates from entering the surface water. Most ecologists define buffers as consisting of deeply rooted native trees and shrubs. Our research indicates that other plants, such as turfgrasses, may function equally well, at least under golf course conditions. Nitrate concentrations in the streams running through the golf courses were measured at the inflow and outflow points (see Figure 3). For almost every sampling date, outflow concentrations were equal to or, more often, less than the inflow concentrations. This suggests that the shallow groundwater seeping into the stream was cleaner than the stream inflow and that it was diluting the nitrate already present. The results support the findings from the lysimeters and wells, namely that the golf course was not a significant contributor of nitrates to the surface water. These data present a comprehensive picture of nitrate dynamics on golf courses planted in bermudagrass. They indicate complexity within the turfgrass system at both a spatial and temporal level, but also document that a properly managed turf is an excellent filter for removing nitrate from the soil and keeping it out of streams. Further, bermudagrass appears to be a reasonable plant system for riparian buffers, especially where trees and shrubs are functionally incompatible. T

onument™ (trifloxysulfuron-sodium) and Revolver™ (foramsulfuron) are two of the most common sulfonylurea herbicides used for controlling over-seeded perennial ryegrass in bermudagrass golf and sports turf. Turfgrass managers have frequently complained, however, about sulfonylurea herbicides performing below expectations. In a transition-zone climate, temperatures can fluctuate widely during the time of year that these herbicides are used. Although cold temperatures have been suspected as a reason for decreased control of cool-season grasses, little is known about the severity or duration of performance-inhibiting cold temperatures. To characterize this cold-temperature phenomenon, we initiated research in February 2006 (in Blacksburg, Virginia).

Non-overseeded perennial ryegrass research areas (one cut at 0.5” and another cut at 2.5”) were selected to receive treatments of Revolver or Monument at weekly intervals from late February to mid-July. Revolver was applied at 17.4 fl. oz./A and Monument was applied at 0.33 oz./A in 30 gallons per acre. Non-overseeded perennial ryegrass was used to remove the variable of bermudagrass competition, which would not be consistent through the duration of the trial. Weather data was collected using Watchdog (Model 800) weather stations located at each site.

Monument. Perennial ryegrass control nine weeks after treatment with Monument was not correlated to temperature and tended to be inconsistent at both high and low temperatures. Revolver tended to control perennial ryegrass consistently when the average temperature for five days before and after treatment was 65° F or higher. Despite some inconsistencies, Monument controlled at least 70% of perennial ryegrass 65% of the time when temperatures were below 65° F and 67% of the time when temperatures were above 65° F. In contrast, Revolver™ controlled perennial ryegrass equivalently only 10% of the time at temperatures below 65° F and 88% of the time when temperatures were above 65° F. In short, Monument is more effective than Revolver when average temperature is below 65° F.

Research Results at a Glance • When using Revolver, the minimum average daily temperature should be 65° F or higher. • Monument is less affected by cold than Revolver. • Monument was less consistent (plot to plot variability) than Revolver.

Several things may cause poor herbicide performance. Let’s examine a few other reasons sulfonylurea herbicides like Monument and Revolver may perform poorly: • The target weed was stressed due to heat, drought, disease, etc. As a rule, you want the target weed to be as happy as possible when you apply an herbicide. Any stressful condition, such as extremely cold temperatures, will reduce the effectiveness of the herbicide. • Rain fell soon after treatment, or turf was mown soon after treatment. Both Revolver and Monument depend on foliar absorption to maximize effectiveness. Post-treatment mowing or rainfall can limit translocation of the herbicide throughout the plant and reduce control. • Errors were made in mixing and calibration.

rate will be less effective. Among the more common mixing errors are worn, clogged or inconsistent spray nozzles. If the agitation system in your sprayer is not operating efficiently, or is not given enough time to dissolve or mix the herbicide, perennial ryegrass control will be poor early in the spray event and will improve dramatically as most of the herbicide is dispensed later, when it is fully mixed in the spray solution. • Water quality was poor (hard water, or pH was 2 units above or below 7). Most spray solutions contain water as the carrier. Sulfonylurea herbicides tend to react with water and will become deactivated over time. If your water has a pH of near 7, the herbicide can remain mixed in the tank for a day or more without major problems. If your water pH is near 4 or 9, half of your herbicide may be gone in just four hours. • The weeds were large, and/or the bermudagrass was not competitive. Bear in mind that healthy bermudagrass plays an important role in perennial ryegrass control. Areas such as the center of athletic fields typically have thin bermudagrass and large perennial ryegrass. These sites will need higher rates or sequential treatments for

EYE ON BUSINESS The Audubon Cooperative Sanctuary Program… Good for Golf, Good for the Environment By Chris Hartwiger and Patrick O’Brien, USGA Green Section, Southeast Region

In

June 2006, Hoover Country Club in Birmingham, Alabama, became the first golf course in the state of Alabama to become fully certified in the Audubon Cooperative Sanctuary Program (ACSP) for golf courses. Hoover Country Club’s golf course superintendent, Doug Trosper, led the efforts to achieve this historic accomplishment. In this article we will review how and why Mr. Trosper led the effort at Hoover Country Club to become fully certified and why following his lead will be good not only for your golf course, but also for your career as a golf course superintendent.

What is the ACSP?

The information contained in this section is quoted from the Audubon International website. Much more information on the program can be found at www.auduboninternational.org. The ACSP is an award-winning education and certification program that helps golf courses protect our environment and preserve the natural heritage of the game of golf. By helping people (1) enhance the valuable natural areas and wildlife habitats that golf courses provide, (2) improve efficiency and (3) minimize potentially harmful impacts of golf operations, the ACSP serves as vital resource for golf courses.

CONTINUED member take stock of its environmental resources and any potential liabilities and then develop a plan that fits its unique setting, goals, staff, budget and timing. The program is easily tailored to a variety of different types of courses, including private clubs, public and municipal courses, PGA sites, nine-hole facilities, resort courses and golf residential communities. Audubon International provides information to help golf courses with: • Environmental Planning • Wildlife and Habitat Management • Chemical Use Reduction and Safety • Water Conservation • Water-Quality Management • Outreach and Education By implementing standard manage-ment practices in these six areas, a golf course is eligible for designation as a Certified Audubon Cooperative Sanctuary, improving its stature and reputation.

Getting started at Hoover Country Club

In the late 1990s, Doug was employed as an assistant superintendent at The Farm Golf Club in Dalton, Georgia, while they worked toward certification. One of Doug’s goals when he arrived at Hoover Country Club was to participate in the Audubon Cooperative Sanctuary Program and to have the club reach full certification status. In 2005, Doug seriously began pursuing certification. One of his biggest hurdles was getting started, and Doug believes this is the barrier that keeps many golf courses from seeking certification. Once the process was underway, however, Doug realized that he could delegate many of the tasks. All he had to do was ask. Once Doug received certification in two or three of the categories, he saw that the end was in site, and he pushed through to reach his goal. In June 2006, Hoover Country Club received word that they had received full certification in the ACSP Program.

The Audubon Cooperative Sanctuary Program for Golf Courses… Saving you money and time! In spring 2001, Audubon conducted a survey of participants in their ACSP program. Here are just a few of the results. Since joining the program: • 75% of participants have reduced their pesticide costs. • 60% have reduced their water costs. • 92% are using pesticides with a lower toxicity level. • 82% have reduced their pesticide use on the property. • 80% have decreased the amount of managed turfgrass on the property. • 100% report that playing quality has either improved (46%) or remained the same (54%). • 97% report that golfer satisfaction has either improved (46%) or remained the same (51%). • 100% report that their own job satisfaction has either improved (70%) or remained the same (30%). Clearly, being a ACSP participant can help you reduce maintenance costs and labor, while making your golf course a more enjoyable place for your golfers, your staff and you!

Name the

Critical Component

Look closely. It’s not the fairway or greens mowers. Is it the irrigation system? Nope. The Sand Pro? Guess again. Give up? Look there on the Workman. It’s you, the golf course superintendent. At Smith Turf & Irrigation, we know that without your guidance, even the best equipment won’t perform crucial tasks at optimum performance levels. So we work hard to understand your goals and then deliver the products that will help ensure your success. And while there are many other essential elements to achieving great course conditions, they all require solid, dependable service and support. At STI, we do that better than anybody else. We’re with you every step of the way.
