Bermuda Grass Fertilizer

The amount and frequency of fertilizer required depends on the desired appearance and growth rate of the turf, length of growing season, soil type, Bermuda grass variety and the use of the turf.

Where high quality is of critical importance and the turf is mowed frequently, 1 to 1.5 pounds of nitrogen per 1,000 sq. ft. per month may be applied during the growing season. The lowest rate of nitrogen that can be applied and still maintain acceptable Bermuda grass turf for sports fields and golf courses is about 0.5 pounds of N per 1,000 sq. ft. per month.

Nitrogen fertilizer can be applied to the soil surface immediately prior to planting or at the time of planting at a rate of 1 pound per 1,000 sq. ft. or 40 to 50 pounds per acre. Nitrogen should be applied 3 to 4 week intervals until a cover is obtained.

Sandy soils require light but frequent applications of nitrogen because of low nitrogen retention. Sandy soils are also typically low in other nutrients such as phosphorus and potassium and these nutrients must also be provided through fertilization.

Potassium is particularly important because of its contribution to root growth, environmental stress tolerance (heat, cold and drought) and wear tolerance. Potassium has also been found to reduce susceptibility of Bermuda grass to leaf spot diseases.

Soil tests are required to determine phosphorus, potassium, calcium and other nutrient deficiencies.

Bermuda grass tolerates a wide range in soil reaction, but performs best between pH 6.5 and 8.0. At pH levels below 6.5 limestone should be added according to soil test recommendations.
