Effects of Clippings and Fertilizers on Warm-Season Turfgrasses
Six warm-season turfgrasses were established on a clay-loam soil to determine the effects of clippings and nitrogen (N) fertilizers on growth and appearance. Ammonium sulfate produced higher clipping yields and tissue N content than Milorganite. Using 0.5 lb. N from ammonium sulfate per 1000 sq. ft. Recycling clippings increased growth without a reduction in tissue N content or general appearance. Compared with other grasses, ‘Prairie’ buffalograss and bermudagrass cultivars generally had greater tissue N levels and growth. The growth and quality of ‘Georgia Common’ centipedegrass declined during the second year of the study. General appearance ratings for ‘Emerald’ zoysiagrass declined during the second year at higher N rates supplied by ammonium sulfate.
