Greens Drainage Preventative Maintenance

Now that the rainy season is upon us, and summer not far behind, it is the perfect time to perform some preventative maintenance on our greens drainage.  As you can see from the picture above, Joe Miller, our irrigation/drainage technician, spent some time this week flushing clean water through the drainage pipe under the greens. Joe uses a special nozzle, pictured to the right, that does a great job clearing out any debris found in the pipe.

Over time, the drainage system will collect debris and may eventually become clogged.  During frequent irrigation, or rainy weather, the soil inside the greens can fill up with water rather quickly.  A clogged drain doesn't give the water anywhere to go, therefore the root zone will become saturated and stay that way.  This causes the greens to become very soft, disease is more frequent, and the roots will die back up to the surface (making them very short).  This compromised root zone does not allow the turf to handle all the typical stresses of summer, and often results in thin, or dead, turf.

Realizing how important the drainage system is to our success, flushing out the drainage has become a fixture on our annual preventative maintenance schedule.  We feel that by keeping our drainage system working properly, as well as a comprehensive cultivation program, we have the best chance to maintain quality putting surfaces year to year despite whatever weather challenges we may face.

Course Update for March

March has always been a transition month in this part of the country.  Some years it can be warm and give you an early start to the season.  Other years, it can be cold and just another month of winter.  Most often it's a little bit of both.  This year March started off mild and had all of us thinking we would get an early start to spring.  Leading up to, and during, core aeration in mid-March, the temperature was above average and had all the short-cut turf waking up rather quickly.  Since then, we've had a handful of frosts that have effectively shut down any additional green up.  We've actually lost color since mid-March.  This is the most frustrating part of spring in this part of the country.  You get excited about greening up and getting a good start to the growing season, and then winter reminds you that it's still early and not done yet.

Aside from the weather, the staff was very busy,
not only finishing up our winter to-do list but, working on preparing the course for the season.  Core aeration on greens, stump grinding, course wide pre-emergent application, topdressing divots on tees, and mowing all surfaces. March is also when our seasonal staff begins to return and so much of our time was spent training them on course setup and other tasks.

With March behind us, and much of the critical spring work is completed, we can begin to settle into our maintenance programs and groom the course as it continues to wake up from winter.  Over the next 30 days, we will continue to acquire/train staff, increase mowing schedules, and ramp up our cultural programs (venting, spiking, verticutting, topdressing).

Spring Pre-emergent Application

Another key project the grounds staff completed this week, was our spring pre-emergent herbicide application to all Bermuda on the golf course.  This application is very time sensitive and critical to the overall cleanliness of the golf course during the season.  When dealing with pre-emergent herbicides, timing is very important.  I'd rather apply two weeks too soon than a day late.  Pre-emergent products are, by definition, only designed to control weeds before they germinate.  Therefore, if you wait too long, and the weeds germinate, there will be no control of the weeds and your time & money is wasted.  The general time frame to control summer annual weeds, with pre-emergent herbicides, in this part of the country, is mid-March to mid-April.  So if any of you homeowners are reading this and have been putting it off, get out and put down your pre-emergent products in the next week or so before it's too late.  

As you can see from the picture above, the pre-emergent was applied using our fertilizer spreader.  Purchasing the herbicide coated on a fertilizer granule is the most efficient and cost effective application method.  It took our staff less than two days to apply the product versus almost two weeks if we sprayed it using our spray rig.  A little accuracy is lost during the application by using this method, but the savings in time make up for it.  This application will keep our weed pressure down until the product starts to wear off in mid-August.  We will then go out with another product in late September to guard against winter annuals.

Stump grinding

This week,  we rented a stump grinder and removed all the tree stumps throughout the golf course.  Many of the tree stumps were left over from some tree work this past winter, however, several of them have been around for much longer.  Several of them are a couple of years old and we just hadn't been able to get to them.  Removing all the old stumps around the course will make it easier to mow and reduce the amount of trim mowing we have to do.

Spring Greens Aeration

March, in our part of the country, is the beginning of the golf season.  It is also when many parts of the golf course begin to wake up from their winter slumber with the Bentgrass on the greens being the first turf to wake up.  Although we may mow and change cups occasionally leading up to mid-March, once we core aerate, that seems to be the beginning of our season.  As turf growth increases, the staff will begin to input more resources (topdressing, fertilizer, verticutting, handwatering, etc).  One of the most important processes we can do to maintain great greens is core aeration.
Core aeration is critical to the overall success and sustainability of the putting surfaces.  Aeration improves plant health by improving the oxygen content, and drainage capacity of the soil.  Improving the oxygen content helps encourage healthy soil biology and allows the turf to cope with all the stresses we throw at it throughout the season (low/frequent mowing, foot traffic, shade, heat, etc.).  

The process physically removes cores of soil and turf at a designated diameter and spacing.  We use those parameters to determine the total amount of material removed each time we aerate.  Once the cores are removed and then cleaned off the green, pure sand is added to the surface and then brushed into the holes.  The sand is added into the holes for two reasons.  First, it stabilizes the soil, because that many open holes would leave the green soft and almost unplayable.  Second, it helps dilute the organic material in the soil that couldn't be removed during the process.  As you can see from the pictures to the right, a lot of material is removed during the aeration process.  This will firm up the greens and allow us to maintain optimum plant health throughout the season.  A follow up aeration will be performed in September.

DryJect Application on Greens

Last week, the grounds staff brought in Robert Main, with Turfgrass Solutions, to use DryJect machines on select areas on the greens.  The DryJect process uses water pressure to fracture the ground and decompact the soil.  This water then creates a void that is filled with sand or another amendment.  The quick blast of water creates a vacuum which pulls the sand from the hopper above, down with it as it leaves the nozzle.  The graphic to the right shows the process.

Although the process is violent and is aggressive in the soil, at the surface all that is left is a small amount of sand at the top of each hole.  After the machine is through, the green is then rolled and brushed to smooth the surface farther.  We completed this project last Thursday and did not close any holes.  In fact, the member skins game played on the competed greens hours after we'd finished and they couldn't believe how smooth and fast they were.  Then on Saturday morning, while I was on the 1st tee chatting with members about the process, I was very pleased to hear the number of compliments on the process and final result.

Although the DryJect process creates channels of sand in the profile similar to a traditional core aeration, it is not meant to replace the traditional hollow tine core aeration process.  Rather, it is meant to be a supplement to an already established program.  After discussing the process with the rest of the staff, we feel that this process could be a great option if our soil tests dictate more aeration is needed but cannot withstand the amount of surface disruption and lost revenue from discounted rounds and lost play during the height of the golf season.

Service Vehicle

The spray rig with the tank and booms removed. Ready for the next step.
A month ago, during some winter weather, the staff spent a few days repurposing our old spray rig into a service vehicle for Dan Welborn, our equipment manager.

I've wanted our equipment manager to have a service vehicle for several years but never felt we had a viable option until recently.  A few years ago, we bought a new John Deere spray rig but decided to keep the older Cushman spray rig so we could use it as needed.  Over the past few years, we haven't used it nearly as much as we anticipated and it has sat for over a year collecting dust in our chemical storage room due to costly repairs to the spray module that would be needed.  I decided that it wouldn't make any sense to spend over $3,000 to get it back into condition as a spray rig.  Although the spray module was a mess, the vehicle was still in good mechanical shape.  The staff disassembled the module and we took stock of the condition of the vehicle and decided to proceed with the project.  The picture above shows the vehicle with the spray tank and booms removed.

The most involved part of the project was fabricating the flatbed and attaching it to the frame of the utility vehicle.  As you can see from the pictures to the right, stock steel was purchased and each piece had to be custom made to fit.  The whole process took two days.  Once the flatbed was welded together, it was primed and painted.

The last step was to bolt all the accessories to the flatbed.  The purpose of the vehicle is to allow the equipment manager to quickly react to an issue on the golf course quickly so that equipment downtime is minimal.  Service vehicles will be outfitted differently at each golf course due to different demands.  Each accessory chosen reflects the common problems that Dan will face throughout the season.  A generator to supply power for various hand tools, a compressor for tire work, a tool box full of various hand tools, storage for tire patch kits and other misc. supplies, a vise for various tasks, and a winch mounted under the back for helping machinery when they get stuck.  As you can see from the final picture at the bottom of the post, there is still some space available along the passenger side for additional storage box and some undermount boxes behind the rear wheels.  These will be purchased next year when funding is available.

The staff did a great job taking an old machine that wasn't in use any more and making it useful again.  We are excited to have the vehicle in our fleet and expect it to be very useful throughout the year.

All painted! Ready for tools

Finished product!

Golf Industry Show

I'm a little late in writing this post, but a few weeks ago, Michael, my assistant, and I were fortunate to be able to attend the Golf Industry Show in San Diego, California.  The GIS is the annual Golf Course Superintendent's Association of America trade show and educational conference.
Lots to see w/ over 250,000 sq.ft. of exhibitor space

The Golf Industry Show is the place to network with industry peers across the country and the world.  The numerous educational seminars offer a wide variety of topics for superintendents to sharpen their skills and the trade show offers all the latest and greatest the manufacturers and suppliers have to offer to the industry.  It never fails in the few short days that I get to attend, I come away with something new to offer our club.  Whether it's new techniques to improve course conditions, or a new way to complete an in-house project more effectively, meeting new friends or catching up with old friends, the GIS offers many ways to come home invigorated and mentally ready to give the upcoming season my best effort.

Goodbye San Diego!

Bluebird Nestbox Program

One of the biggest reasons I got into the golf business is to work outside and enjoy nature.  I firmly believe golf courses are an integral part of the environment and are often the only place where wildlife can live as communities continue to grow.  As the golf course superintendent at Bailey Ranch Golf Club, I have a direct impact on our facilities environmental footprint, and I take that responsibility very seriously.  There are numerous ways we, as a facility, work towards environmental stewardship such as: water conservation, soil testing, scouting for disease and pests, reducing maintained acreage, grass buffers along pond banks to improve water quality and encouraging wildlife habitat.

Wildlife habitat is one of the best ways a golf course can benefit the environment.  With this in mind, one of my big initiatives last year was to begin a bluebird nest box program.  With the help of the Oklahoma Bluebird Society and the Oklahoma Department of Wildlife Conservation, we constructed and placed 12 nest boxes throughout the golf course.  We then monitored the boxes throughout the year so we could track any progress.  At the end of year, we submitted our results to Oklahoma Department of Wildlife for their Bluebird Nest Box Survey.  We just got their final report and it seems that Bailey Ranch Golf Club was the only entity, public or private, that reported any results in Tulsa County.  Although we only had three nests and 24 fledglings, I'm pleased with the progress we made in our first season. As the program continues to grow, our goal is to have nests in every box each season, and eventually expand the program into other areas throughout the property.

Irrigation Work on #4 Tee

Today, the grounds staff reconfigured an irrigation station between the forward tee and the fairway on #4. This area has always had poor irrigation coverage and therefore the quality and density of the turf in this area, has been largely dependent on the weather.  It was decided that adding a head, and moving an existing head, would improve the coverage and make it easier to grow better turf in this area.

 The picture below describes the work that was completed.  The red lines and circles show the current layout of the system, with the lines showing the pipe locations and the filled red circles showing the location of the full circle (360 degree) heads.  The yellow lines and circles show the new head and pipe layout with the half circles describing part circle (180 degree) heads.  A part circle head allows us to irrigation along the path while not spraying the houses left of the path, and also watering the in-play Bermuda and not the native along the right side.
