March 30, 2012 -- Volume 50, Number 07         Lost Grass?  What to do about it. by Stanley J. Zontek, director, Mid-Atlantic Region Not every golf course has a good stand of grass every year and under every weather condition. Eventually, turf will be lost somewhere. The challenge is to effectively manage that turf loss curatively as well as preventatively. Every golf course superintendent will lose grass at some point in his or her career. For that matter, no golf course superintendent is perfect; no budget is so complete as to allow everything to be in stock and available when a problem arises; no golf course has perfect soil; there is no perfect irrigation system or pure water for golf course irrigation; no perfect surface and subsurface drainage; and few have beneficial growing environments for turf, such as full sunlight and complete air circulation for every green, tee, and fairway. Not every golf course has the correct grass growing in the right places. Golf course superintendents are pretty good at what they do in this industry, but turf loss still occurs, sometimes in spite of the best efforts.   A certain amount of turfgrass management relies on luck, some good and some bad. For example, did your course receive that torrential downpour that dumped two inches of water in 30 minutes on the course, or did you miss that storm and don't have to worry about washed-out sand bunkers, wet wilt, scald and Pythium? There is an element of luck in everything associated with growing grass outdoors. Sometimes you are lucky and sometimes you are not. The skill of the superintendent or the strength of a budget (or even the best grasses) cannot overcome bad luck with weather.   Read the rest of this article        A Warm Spring Is Good For Golf, But...   Warm, early spring conditions have been great for golf, but, remember, many courses are not yet fully staffed and pest management programs may require adjustments. by the USGA Green Section Forsythia bloom, a common plant indicator for turf managers to apply preemergent herbicides for crabgrass prevention, is three to four weeks ahead of schedule in many parts of the U.S. Tee it up! Golf activity always parallels the weather. A mild winter and warm early spring conditions have been welcomed by golfers across the country. Golfers are not the only ones loving the weather, however, as golf facilities are seeing boosts in early season revenues. Obviously, the unanticipated financial gains are important to all golf facilities, but especially helpful to courses that suffered abysmal margins last year due to extreme weather conditions, most notably the severe drought in the southern U.S. and excessive rain and heat in many Midwestern and northern states.   As golfers gain an early start honing their game in 2012, golf course superintendents are busy with course preparations roughly a month or more ahead of schedule. Staffing is limited at this time and the labor hours available are typically reserved for completing off-season projects, such as drainage installation, tree maintenance, bunker renovations, etc. With full staff levels still several weeks away, turf managers are scrambling to condition golf courses to meet expectations while still trying to complete scheduled off-season projects.     Labor is the largest line item in a golf course maintenance budget, so the obvious concern in bringing seasonal employees back early is an effect on the bottom line. An early start to the golf season equates to an extended golf season, and this requires more labor and resources for course conditioning and setup. Operating budgets are determined well in advance and on the assumption of a golf season more typical in length. Unless serious adjustments are made to the "to do" list, it is unlikely that turf managers can operate within the approved operating budgets created months in advance. Keep these early-season expenses in mind as the season progresses. In addition to labor concerns, a few other factors need to be considered as they relate to the early spring.   Read the rest of this article       Long-Term Diet  Research at Michigan State University provides evidence that fertilizing more than the turf can use results in unwanted nitrate leaching. by Jeff Nus, manager, Green Section Research Dr. Kevin Frank (shown) and his colleagues at Michigan State University have been monitoring leaching of nitrate-nitrogen and phosphorus from turf plots at Michigan State University for more than two decades. At the start of each year, many of us feel compelled to make New Year's resolutions, and it is not surprising that one of the most common resolutions is to lose weight. Perhaps we need a long-term diet?     Maybe that should be the view for fertilizing turf as well. Long-term research at Michigan State University (MSU) suggests that as turf sites age, it may be necessary to reduce the amount of nitrogen (N) fertilizer to lower the risk of nitrate leaching. Golf course superintendents have a responsibility to protect the environment, including the quality of surface and ground water surrounding and beneath the golf course. If fertilizer rates are higher than the turf and soil microbes can use, the threat of nutrient runoff or leaching increases substantially.   Between 1989 and 1991, four large (3.75 ft. diameter by 4 ft. deep) lysimeters were constructed and installed at Michigan State University's Hancock Turfgrass Research Center. After installation, the area was sodded with a blend of Kentucky bluegrass cultivars including Adelphi, Nassau, and Nugget. From July 1998 through 2002, turf growing over the lysimeters was treated annually with urea at a low nitrogen (N) rate of 2 lb./1,000 ft2 (0.5lb. N/1,000 ft2 per application) or a high N rate of 5 lb. N/1,000 ft2 (1 lb./1,000 ft2 per application). Application dates were in May, June, September, and October. As of 2011, the turfgrass area has been under continual fertilization practices for 21 years. Michigan State University scientists analyzed leachate for nitrate-nitrogen (NO3-N) since 1998 and gained a good understanding of the dynamics of turfgrass nitrogen use as Kentucky bluegrass turf matures over several years.   Read the rest of this article  All Things Considered - A Green Section Staff Opinion Unreasonable Expectations Expectations may be great but standards should be reasonable by Robert Vavrek, senior agronomist, North-Central Region   Well-defined maintenance standards provide the guidelines that define course conditions for day-to-day play. Reasonable standards are an asset to any course, but constantly trying to attain unrealistic goals can drain the maintenance budget and compromise the health of the turf. A short, well-written set of maintenance standards is a valuable document for any private or public golf course. Standards help define what playing conditions golfers can expect to find on the course throughout the season. Green speed for day-to-day play, heights of cut for the various playing surfaces, irrigation practices, bunker maintenance, and schedules for aeration and topdressing are examples of issues addressed in a typical standards document.   In my opinion, far too many courses spend a great deal of time and effort to develop a set of unreasonable, unattainable standards that only serve to set the table for golfer dissatisfaction. These standards read more like a wish list of what the course hopes to achieve with respect to speed, firmness, bunker conditions, etc., versus what the players will likely experience during an average round of golf.   Maintenance standards fall flat on their face most often when they define and mandate inappropriate playing conditions for a particular time of the season. For example, current standards at a highly regarded course in the North Central Region include a statement that greens will be maintained to provide speeds of 11 to 12 feet from May 20 through October 31.To achieve these standards, the greens will have to be cut short and pushed very hard at the start of the growing season, and this could compromise root growth. Aggressive management well into late fall provides little opportunity for turf to recover from summer stress and harden off properly before winter. Furthermore, have fun punching holes in the greens through the snow. Better yet, try coring greens during April and then try to achieve the unreasonable speed standard by mid-May.   Read the rest of this article         Regional Updates    Florida Region          Headed Toward The Finish Line And Education Opportunities     The 2012 winter golf season in Florida has been one of the best in the past several years. The lack of any significant cold weather has been very favorable to increased play at most courses and at the same time minimizing the impact of peak season play, traffic and wear damage. As the saying goes, "all good things come to an end" and in another few weeks this will be the case with the 2012 South Florida winter golf season. After the Masters, Easter and spring training baseball, seasonal residents will begin migrating north and back to their home courses. No doubt many courses would like to extend the current winter season for as long as possible and maintain maximum revenue flow. With spring arriving four to five weeks early in the north however, a delay in the migration north will probably not occur and with car haulers starting to be spotted around town, there is further confirmation that the end of the season is near.    However, it is not too late to take advantage of an education opportunity prior to the end of the winter season. As USGA agronomists, we see and hear it all. A common concern is always how to get golfers and course officials to understand why basic golf course maintenance practices are so important. Times have changed, and we all have less to work with and greater demands to meet. Doing more with less, or even keeping basic levels of maintenance practices in place is more important than ever before. To help your facility successfully meet such challenges we invite course officials to attend a Regional Golfer Meeting to hear USGA staff explain golf course maintenance practices, why they are important, and the long- and short-term ramifications of cutting back the maintenance program. A USGA rules official will also be on hand to discuss changes in the 2012 Rules of Golf. This is a good opportunity to have course officials hear from an unbiased source and to have all of their questions answered.     To see the Regional Golfer Meeting agenda and sign up to attend, please read the rest of this update     _____________________________________________________________________     North-Central Region        Records Are Made To Be Broken     I just heard that over 6,000 weather records have been broken across the country so far in 2012. The record breaking weather serves to emphasize how challenging golf turf maintenance can be. It also reinforces what should be a cardinal rule - hope for the best, but prepare for the worst.    The timing of product applications is currently 3 to 4 weeks ahead of last year. Of course, a return to colder weather could force schedules to change again. One of the best ways to plan product applications is to monitor growing degree days. The GDD tracker offered by Michigan State University (http://www.gddtracker.net/) is an excellent tool. Growth regulator applications to manage or suppress Poa annua seedheads are a priority for many, and the warm weather pattern this year has necessitated much earlier applications. In addition, the difficult 2010 and 2011 seasons have made pre-emergence herbicide applications for crabgrass control a growing concern at courses throughout the region. Whether your challenges are Poa annua seedheads, crabgrass or spring broadleaf weed control, check out the GDD tracker to improve product timing accuracy.    Disease activity has not been a major issue yet this season in the North Central region, but that could quickly change. Widely scattered pink snow mold (Microdochium Blight) and leaf spot damage has been observed on recent visits while last week's warm temperatures favored Dollar Spot. Here are some links to some helpful sites regarding the incidence and control of turfgrass diseases.    http://www.otgt.org/Bucks-for-Turf-Home/Turfgrass-Disease-Management-Notes-4833.html.    Purdue's turf disease risk forecaster (http://btny.agriculture.purdue.edu/turfcast/) is a good site to monitor.    Dr Vincelli's publication "Chemical Control of Turfgrass Diseases 2012" can be found at  http://www.ca.uky.edu/agc/pubs/ppa/ppa1/ppa1.pdf  and offers in-depth guidance for season-long turfgrass disease management.      Read the rest of this update       Let 'Er Rip    It's not often that turf is "wearin o the green" before St. Patrick's Day at courses across the north-central tier of states. However, little snow cover or deep frost along with recent rainfall and unseasonably warm temperatures during early March have definitely jump-started turf growth and the golf season.    No doubt, both private and public courses welcome the bonus of unanticipated cash flow from early spring green fees and cart revenue in light of the sluggish golf economy during the past several years. Golfers benefit from extra-early opportunities to play their home courses, but let's hope they keep their expectations reasonable with respect to turf quality. Only an April Fool would demand 4th of July playing conditions on Easter Sunday in Minnesota.      Irrigation systems throughout the Region are not likely to be up and running during early March and the average maintenance crew will be operating well below full strength until Memorial Day. As a result, an early opening can be quite disruptive to the turf maintenance program. For example, mild weather during late winter always makes it very difficult to predict when to apply growth regulators for Poa annua seedhead suppression.      Read the rest of this update        _____________________________________________________________________        Mid-Atlantic Region         Everything is Popping! Turfgrass Management Is Truly A Dynamic Business      As a general statement, we are about four to five weeks ahead of "normal" (whatever that is) weather patterns. During a recent Turf Advisory Service visit (TAS), I had the opportunity to sample soil temperatures. At this time of year we normally see soil temperatures in the 30 to 40 degree Fahrenheit (F) range. However, it has been common this spring (and it is now spring) to see readings in high 50's (F) to the mid 60's (F). These elevated temperatures have prompted urgency with regard to implementation of several programs normally performed in early to mid April. The grass is growing!    Mowing has begun for most, if not all courses. However, this early return to turf growth finds most operations shorthanded. Crew call backs have begun but most operations are not up to their full staffing levels. Priorities have to be set! Greens are always the highest priority followed by fairways, tees and then the rough. Golfers should have patience when it comes to playing an errant shot that has found the rough. This pleasant weather has provided an opportunity for golfers to get out on their favorite course much earlier compared to the last several seasons. The grass in the rough will be cut as labor resources allow. These are not neglected areas of the course; it is only March!    Treatments for crabgrass should be completed very soon. In fact, crabgrass has already germinated in bare soil in roughs in the Tidewater area of Virginia. We have reached "that" important soil temperature indicator. Pre-emergent control depends upon product being positioned in the soil before weed germination occurs. This is particularly important for goosegrass. We have had many calls regarding control of this grassy weed. Last year was a stellar year for this weed, particularly in putting greens. Contact our offices if there are any questions regarding control strategies. There is still time to control goosegrass.

The Green Section agronomists are the most knowledgeable, respected, and impartial golf-turf consultants in the world. Backed by the USGA, the Green Section's services provide dependable recommendations that course officials can count on. First started in 1953, this service permits individual facilities to reap the benefits of on-site visits by highly skilled USGA agronomists located in Green Section offices throughout the country. Each agronomist visits more than 100 courses annually. Their experience helps golf course staff and officials produce the best possible golf turf for the dollars that can be spent. The TAS's purpose is not to tell anyone how to run a golf course or what products to buy. Rather, it seeks to bring a wealth of information and an impartial yet concerned perspective regarding turfgrass growth requirements, how these requirements might best be managed for golf, and ideas that other golf courses have found to be beneficial.   The Turf Advisory Service is used by the biggest and smallest golf courses. Golf keeps America beautiful, and day after day, year after year, the Green Section helps golf courses produce better turf for better golf.

PG2

Here is a close up pic of the 007 on PG2. It looks good and has almost completely healed from the aeration - it was done just 5 days earlier than the rest of the greens. It still has a little bit of a larger leaf tip than expected. The grass is starting tighten up with the lower we are going with it and should be a sweet surface in a couple of days.

It will probably be open on Tuesday.

Lazy

Laying down on the job when everyone is on a mower trying to get caught up.

Mowing

Finally getting somewhat caught up on mowing this week. Only have a couple more holes to finish mowing rough and all the short grass has been cut this week.

Greens

Mowed greens for the first time after aeration yesterday and rolled greens today. They are coming in good and should be completely healed in another week or so.

Winter wear

Here is a good example of winter wear on bermudagrass and why it is important to limit cart traffic in the off season. You can see a line of brown grass in front of the practice tee where everyone hits driver while on the mats.

Bunkers

The bunkers will get raked tomorrow. As stated in the earlier post we are spread pretty thin with all the stuff we need to get done this time of year. It's important (as always) to rake the bunkers out behind yourself because we just can't get to them with any frequency until the amigos get here.

Bermuda growth

We are pretty far behind on the golf course right now due to the warm spring. The grass has greened up a little earlier than usual, but I've never seen it start growing this early. We usually don't need to start mowing until the middle of April. That being said, we have started mowing what we can while still trying to get greens aerated, pre-emerg down, and spraying herbicides for the spring weeds. The Amigos get here in another week and a half - once they get here we will be able to quickly get the course all cleaned up and mown down. Until then we are spread thin and will do the best we can to keep up.

Aeration.

We are finishing aeration on the greens today. This will be the only time this year we aerate because of the greens project.

I closed the spacing and ran the deep tine Verti-drain over the greens to make sure we hit them good and make sure we can keep them healthy all the way up to the start of construction.

Aeration is one of the most labor intensive tasks that we have to do on the golf course. It takes a lot of time and hard work, but is something that is essential to keep bentgrass alive in our climate.

Poa in greens

Here is a picture of some of the poa in the greens. The growth regulation program we are on has done a good job suppressing the seed heads, but I have seen a little breakthrough. The poa should be thriving for another couple of weeks but then settling down once the nighttime temp rise.

Spring Dead Spot

Here is a picture of #18 fairway with some spring dead spot patches. The S.D.S. was not as bad this year as in years past but a few fairways did have some. We will be aerating and fertilizing these worst areas and with a little heat they should be grown in once the Bermuda really starts growing.

PG2

Attached is the picture of PG2 after aeration and topdressing. We are hand brushing in the topdressing to avoid getting equipment on this green. It should be ready to open the last week in March.

PG2

We aerated PG2 this morning. I wanted to get it done a little earlier than the others to give it time to recover. Once it it recovered and grown in I will open it. We are taking a little more time with opening this one to make sure it is good and strong - I'm sure it will see its fair share of traffic this summer with the rest of the greens being closed.

Once all the new greens are done, we probably will not do this spring aeration on the new greens. There will be no organic matter build up because of the new mix. This green still has organic matter because we did not remove the mix and re-build it - it was planted on the existing mix.

Greens

Rolled greens yesterday. They are rolling pretty good right now. This is the time of year that the poa is really booming, but we are managing it with growth regulators and vertical mowing and grooming. This time of year it always looks like there is a ton of poa in the greens, until the bent wakes up and starts to get going. Once we get into the teeth of the growing season, the bent will start growing a little more aggressive and the poa will not be as noticeable.

Course conditions.

This was a picture taken yesterday just as the golf course was starting to dry out enough to get some equipment out on the course. That was followed by a half inch of rain this morning and we are back to the sloppy conditions.

I did get about 17 acres of rough sprayed before the rain. We are spraying for all the poa and spring weeds that are popping up.

Wet course

The course is very wet right now. It have been a difficult winter to keep the course clean of weeds. All of the rain has kept the course wet, making it difficult to get the sprayers out on the golf course. We have all the priority stuff (tees, fairways and approaches) pretty clean, but the rough is not near as clean as I would like. As soon as it dries out the sprayers will be rolling to get everything cleaned up.

We are getting into the time of year where the course will start drying faster, making it a little easier to get equipment on the grass.
