Drainage Project Follow-Up: Poa annua Effects

After our last post, we received several questions regarding our drainage project and how it might affect our Poa annua. If you've played Adams Pointe recently, you probably haven't noticed many issues with our fairways. But because of the amount of Poa annua on the property and the inevitable summer heat, that will almost certainly change, even with the added drainage.  

No. 3 Fairway showing contrast between bentgrass and Poa annua

The picture above shows two very different shades of green in the No. 3 fairway. The darker green is bentgrass, and the lighter green/yellow on the right side of the fairway is Poa annua. The color difference is partly caused by a plant-growth regulator application to the fairways. This application helps slow vertical growth in the Poa and weaken its competitive ability. The Poa is typically easy to spot, but this spray really illustrates the amount of Poa we have on the property. 

The optimal temperature for Poa root growth and shoot growth is 55 to 65 degrees and 60 to 70 degrees, respectively. Overall, root growth is more important because turfgrass can maintain growth at relatively high temperatures, as long as soil temperatures stay cooler. As you can see with the temperature ranges listed above, we quickly exit optimal Poa temperatures in late May or early June. Once soil temperatures increase beyond that optimal range, it doesn't take long for the Poa to declineAs you continue to visit Adams Pointe throughout the year, you might notice these changes to the Poa. This doesn't mean our drainage project isn’t working, but rather, summer has rolled in temperatures the Poa annua cannot survive. We use the annual Poa loss to our advantage, seeding bentgrass in the affected areas in the fall, hoping it will outgrow the Poa in late fall and early spring. That’s no easy task, as Poa annua is the most widely distributed weed in the world, even documented as an invasive species in Antarctica. Everything from animals to wind scatter its seeds, and during optimal temperatures, it establishes rapidly. We will never completely rid the property of Poa, but with our current management plan, we hope to limit its growth and give the bentgrass every chance to compete.

2016 In Review: Welcome to Water Wick


The WaterWick drainage system trench with minimal disruption to the playing surface.
If you played Adams Pointe last summer from about late July on, you undoubtedly noticed some issues with a number of our fairways. Several factors contributed to the decline of our bentgrass, most notably excess water and heat.

The 2016 golfing season started off relatively normal. Temperatures and rainfall stayed right around average through April. The month of May started off average, but with a wet final two weeks, we finished 2 inches above average in precipitation. Typically, this extra precipitation leading into summer would be cause for concern, but we deal in extremes in this part of the country, and last June was extreme to say the least. Every single day hit 85 degrees or above, with 18 days at 93 or higher. During the heatwave, we went a stretch of 22 consecutive days without precipitation and ended the month with 1.45 inches of rain, or 3 inches below average. Despite the record warmth of June, course conditions remained excellent. We can manage moisture levels far more easily when it is hot and dry, rather than hot and wet; It’s easy for us to continue watering but much harder to get rid of excess moisture. And although the days were warm, we were still getting needed relief at night with the average low for the month at 67 degrees.

The floodgates opened in July. In the first three days of the month, we received 4.75 inches of rain. Three days later, we picked up another half inch. The following week, 3.7 inches of rain fell, and by July 17, we had received 8.95 inches of rain, or 3.75 inches above the monthly average.

Water sits on No.15 fairway after one of the many downpours of 2016.
Then the heat turned on. The average high temperature from July 17 through July 25 was 97 degrees, and the average low for that same span was 76 degrees. This time frame caused the most damage. With saturated soils, these temperatures essentially "bake" the turf roots, causing soil temperatures far greater than bentgrass can withstand.

And high soil temperature wasn’t the only factor. Due to the design of our fairways, almost all holes drain toward the middle, causing these areas to stay saturated longer. Poa annua then thrives in these areas early and is the first to turn south when the temperatures increase. What is under the fairways also plays a large factor. With the exception of our greens, our soils are very heavy clay. This prohibits adequate water movement and drainage and causes areas to stay more wet than they would in sandy soil. Adding in compaction from foot and cart traffic, lack of air movement from trees and/or weather patterns, and the constant disease pressures, your Adams Pointe crew had quite the stressful summer.  

With July’s initial rainfall, we began doing all we could to slow down the inevitable decline. We started flagging heads for Aerwaying on July 6, beginning July 7 with the holes that traditionally suffered the most. Below is a slow motion video showing the Aerway process. The blades slice narrow channels in the turf, allowing enhanced water movement and increased oxygen to the root zone. Volume warning here.


It was a slow process that, with interruptions due to storms the following week, took us about six days to complete. Seeing those storms in the forecast, we also planned a fairway application of a soil penetrating surfactant. This application helped improve vertical and lateral infiltration through the soil profile. This was another slow process, but we were able to complete it by July 14, just as we hit 8.9 inches of rain for the month.

#6 Fairway - July 31, 2016
#6 Fairway - August 31, 2016
We ended August with 9.6 inches of rain, almost 4 inches above average. In the latter half of the month, we started seeing cooler overnight temperatures, providing desperately needed relief to the turf. Starting August 16, we began seeding fairway areas that declined through the summer. As you can see in the picture above, by the end of August, we had made a lot of progress in the recovery efforts. In mid-September, we began laying sod in the areas that were not established with seed. In the span of a couple weeks, we were able to lay more than 6,000 square feet of bentgrass sod. We took sod from the No. Four fairway and were able to reestablish that hole with seed very quickly, with optimal growing conditions in September/October. 

After spending the off season weighing options about how to address the summer decline of our fairways in a cost-effective and minimally disruptive way, we decided on the Water Wick Drainage System. The Water Wick system is essentially a vibratory plow that creates a trench through the soil while injecting gravel into that trench. The process creates new channels for water to drain, thereby aiding our existing drainage. On March 16, we trenched more than 4,700 feet across nine of our most troublesome holes. Volume warnings again.



We again focused on areas that traditionally show the most stress during the summer and trenched along both the existing drainage lines and areas around our drainage boxes. In order to avoid damage to our boxes, we trenched those by hand. Once at the box, we simply drilled a few holes in the side to allow water to escape. Here's a short video showing the water after the first hole is drilled.


After connecting trenches to boxes, we went back through and sodded some of the bigger gravel areas. Any smaller trenches with exposed gravel should grow over quickly, creating a drainage system that is virtually invisible to our patrons. While the Water Wick system can utilize up to three plows at a time, we were only able to use one plow at a time, because of our extreme clay soils. Due to this and other time constraints, we were only able to complete half of what we had hoped for this spring. The current plan is to go back at it this fall, trenching on the other side of the drainage lines we did this spring, as well as a few holes we didn't get to.


As with any option available, this is not a fix-all; We will never make it through any season without experiencing some turf loss. What we will do is continue to remain observant, informed, and proactive to produce the best playing conditions possible year-round. We’re looking forward to seeing the improvements from the Water Wick system this season, and we’re just hoping it doesn't immediately get tested with 20 inches of rain!

Parks Maintenance Sales Tax Initiative

On April 4, residents of Blue Springs will have the opportunity to vote on a sales tax initiative to benefit city parks. The proposed initiative would increase Blue Springs’ sales tax by one-half cent, which equates to 25 cents for every $50 spent inside the city.

Estimated to generate approximately $15 million during a five-year periodthe tax would help address major concerns in the city’s parks and trails and would allow Adams Pointe to make important upgrades to its facilities. If passed, the tax is slated to address the following deterioration issues at Adams Pointe:
  • Replacement of clubhouse roof
  • Bunker repair and replacement
  • Main drive replacement
  • Cart path repair and replace

These improvements would allow Adams Pointe to continue offering quality recreational opportunities for the entire community while improving guest experience.

Aerification Alert!

A note to our golfers: The course will be closed Monday, March 20, for aerification. Future posts will highlight the many reasons why this cultural practice is vital to the long-term health of the course. In the meantime, check out this fact sheet from Utah State University for any questions you may have.

http://extension.usu.edu/files/publications/publication/HG_Turf_2006-02.pdf

Unfortunately, it will take a little longer than in the video above. We look forward to seeing you on Tuesday.

Meet Our Staff

Welcome to the Adams Pointe Golf Club maintenance blog! Our hope is to provide our patrons with useful, timely information about general maintenance at our course. We will add content from standard course care to comprehensive details about our agronomic practices. But first, lets meet our staff.

Randy Shatzer, Superintendent:


Randy has been Adams Pointe’s superintendent since September 1998. Prior to his tenure here, Randy was assistant superintendent at Milburn Country Club in Overland Park, Kansas. With almost 20 years’ experience on this property, Randy is well accustomed to the challenges presented in growing cool-season turf grass in an unforgiving climate. His vast knowledge proves a great asset every season. 



Brian Neufeld, Assistant Superintendent:

Brian joined Adams Pointe in May 2013, after relocating from Jackson, Wyoming, where he served as second assistant superintendent at Jackson Hole Golf and Tennis Club. Brian’s irrigation and varied turf grass experience – from cold to desert environments – help Adams Pointe address threats to the course. 

Mickey Fleeman, Equipment Manager:

Mickey began his career at Adams Pointe in April 1998, after serving as equipment manager for Ironhorse Golf Club in Leawood, Kansas. He has been invaluable to Adams Pointe, using his decades of equipment repair and preventive maintenance experience to keep our course machinery running.
