Abstract/Contents: | "Nitrogen (N) from water-soluble fertilizers is frequently applied to turfgrasses. However, there is considerable environmental concern over water-soluble N leaching from turfgrass. 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 fertilisation. In a field study, turfgrass response was evaluated for new and standard controlled-release N sources. Twelve coated-urea N sources were compared over two study periods along with isobutylidene-di-urea, ammonium sulfate (AS), and three controlled-release urea sources + AS at 7.5 and 15 g N mā»Ā² 3-monthsā»Ā¹ and AS applied monthly at 5.0 and 2.5 g N mā»Ā² for their effect on Cynodon dactylon x C. transvaalensis cv. Tifgreen grown on Hallandale fine sand (Siliceous, hyperthermic, Lithic Psammaquent). Evaluations were based on turfgrass quality ratings and clipping yields. Turfgrass quality and clipping yields were significantly (P<0.01) affected by N source and N rate. However, no consistent differences were found among controlled-release N sources. Generally, a single application of controlled-release N sources resulted in similar or better turfgrass quality and greater clipping yields than a single or monthly applications of AS that provided an equivalent amount of nitrogen over the study period." |
