Dr Andrew McNitt discussed the fundamentals of turf grass management for athletic fields as part of the STMA Midwest Regional Conference in Ames, IA, June 24-25, 2009. He related many of his tips to several of the field plots that Dr Dave Minner was conducting at the ISU turf plot area as part of the trade show the previous day.
Here are the ideas that were shared with the conference attendees:
- Keep the mower height constant and mow often. Stress in August (less water and a lower height with sports field use) is the worst time to change the mower height.
- When removing grass clippings you are removing one third (1/3) of your fertilizer. This is another reason for mowing more often to minimize the thatch.
- Fast release fertilizer (urea) is the most effective for healthy turf grass. Light frequent applications that must be calibrated is perferred. Phosphorous is held by the soil so if there is mature grass there should be very little danger of having a phoshorous run-off in to surface water drainage. Dr. Minner's turf plots reflected this recommendation based on the fertilization amounts and the rates of application.
- Penn State (Beaver Stadium) turf grass specialist implements a "lean & mean" practice in September by cutting back water and fertilizer. You don't want the grass to lush otherwise you'll increase the damage due to divots from traffic.
- Don't skip on the quality of seed. The critical note is to buy the grass seed by weight not by seed count! For example a seed mixture that is 80 percent Kentucky Blue Grass and 20 percent perennial rye grass by seed count will actually be 50/50 by weight. Since Kentucky Blue Grass takes so long to establish the Perennial Rye Grass will just out compete it given this percentage by weight results. Dr McNitt stated for high use areas to seed with perennial rye grass because it quickly establishes itself. He supported Dr Minner's research results in that it far better to reseed at a much higher rate one time then to make repetitive seeding with smaller amounts. Dr Minner's turf plots posted in photo album format reflected these recommendations.
- Tall Fesc)ue needs to go through 2 cool seasons (e.g., spring and fall, or fall and spring) to provide a wear resistant capacity.
- Consider using good quality compost in your fertilization and seeding process.
