Several aspects of fertilization are critical to the development of a healthy turf on any playing field. Applying fertilizer at the right time is as important as using the right fertilizer. Fertilization should be determined from soil test analysis for pH, phosphorus and potassium needs.
On a sports field that receives frequent use, potassium is as important as nitrogen to the survival of the turf. High potassium levels in grass tissue greatly increase the wear tolerance of grass. Apply potassium at about the same rate as nitrogen.
- Nitrogen is required to produce a good turf, but it should be available to the grass at low and uniform rates.
- A single application of fertilizer should not provide more than 1 pound of soluble nitrogen per 1,000 square feet.
- On a newly planted field this amount of nitrogen should be applied at 2- to 3-week intervals.
- For maintenance fertilization, 4- to 6-week intervals are satisfactory.
Timing of fertilizer applications is as important to the vigor of the turf as the rate and analysis of the fertilizer applied. Make applications in the early spring and continue until a satisfactory turf cover develops.
Fields in Grass can provide you with an annual fertilization program.
