Abstract/Contents:"Nitrogen from water-soluble urea-based fertilizers is frequently applied to turfgrasses. However, there is considerable environmental concern over water-soluble N leaching from turf. Use of coated soluble N sources has been promoted in recent years as an efficient N fertilizer strategy. Water-soluble urea may be coated to provide controlled release of N, which can extend the period of turfgrass response following fertilization. In this field study, turf response was evaluated for new and standard controlled-release N and standard slow-release N sources. Twelve urea-coated N sources were compared over two, three-month periods along with IBDU, ammonium sulfate (AS), and three controlled-release urea sources + ammonium sulfate applied monthly at 2.5 g m-2 or 5.0 g m-2 for their effect on bermudagrass (Cyndon dactylon x C. transvaalensis Burt-Davvy cv. Tifgreen) grown on Hallandale fine sand (Siliceous, hyperthermic Lythic Psammaquent). Evaluations were based on N content in clippings, N uptake, and N retention from prills. Nitrogen content, N uptake, and N retention were highly significantly (P>0.01) affected by N source. However, no consistent differences were found among controlled-release N sources. Generally, a single application of controlled-release N sources did not consistently provide greater N content or uptake than single or monthly applications of AS that provided an equivalent amount of N over the study period."
