| Abstract/Contents: | "Forage fertilization practices are changing because of poultry litter use restrictions and reduced NH4NO3 availability. Our objectives were to compare bermudagrass [Cynodon dactylon (L.) Pers.] yield and N uptake among N sources and rates and evaluate the influence of N-fertilizer source on NH3 volatilization. Four N sources, pelleted poultry litter (PPL), NH4NO3, urea, and urea + N-(n-butyl) thiophosphoric triamide (NBPT) were applied at rates of 0 to 500 kg N ha-1 yr-1 to common bermudagrass from 2006 to 2008. Measurements included dry matter yield and total N uptake from each N source applied at 400 kg N ha-1 yr-1. A semi-open static chamber method was used to measure NH3 volatilization for 15 d from each N source applied at 400 kg N ha-1 yr-1 in three split applications. Dry matter increased linearly in 2006 and curvilinearly in 2007 and 2008 as N rate increased, with maximum yields of 9910 to 14,328 kg ha-1. Forage fertilized with ā¤300 kg PPL-N ha-1 yr-1 produced 78 to 96% of the dry matter as the same rates of NH4NO3 The addition of NBPT to urea showed no consistent benefit to yield or N uptake compared with urea alone. Urea-based fertilizers produced similar to slightly lower yields and N uptakes than NH4NO3. Cumulative NH3-N loss was greatest for urea (10.418.7% of applied N), intermediate for urea + NBPT (2.0-3.9%), and <1.5% for PPL and NH4NO3 Given the limited availability of NH4NO3, restrictions on poultry litter use, and concerns about air quality, urea amended with NBPT is a suitable N source for bermudagrass." |
