Environmental losses of soil-applied N-fertilizers through ammonia volatilization were examined. Volatilization trials were established in the vegetative phase of wild blueberry production in Nova Scotia (NS) and Prince Edward Island (PE) in 2004 and 2005. Treatments consisted of no fertilizer (control) and N applications (35 kg N ha-1) of ammonium sulphate (AS), diammonium phosphate (DAP), urea (U) and sulphur coated urea (SCU). When compared with the control, results indicated significantly elevated volatilization rates for U (303% NS in 2004, 274% PE in 2005), SCU (273% NS in 2004, 205% PE in 2005) and DAP (178% PE in 2005). Results indicate that volatilization losses are significant, site specific and may contribute to reductions in nutrient availability.

Abstract With the advance of the no-tillage system (NT system) in Brazil, the adoption of technologies for nitrogen fertilization in these soils become essential for increasing the efficiency of N use in the system. In this sense, the objective of this study was to quantify ammonia losses, N removal in grains, and with 2nd crop yield in NT system and conventional (T system) planting areas that received application of different N fertilizers and their technologies. Ammonia volatilization, N extraction in grains and corn yield in response to the application of conventional fertilizers were compared to urease inhibitors treated urea in NT and T systems. The treatments were: no-N (Control); Prilled urea (PU); urea + NBPT (UNBPT); urea + Cu + B (UCuB); ammonium nitrate (AN), and ammonium sulfate (AS). In the NT system, the N-NH3 losses were 49% greater than in the T system; without differences for corn yield. The fertilizers as AN, and AS had the lowest N-NH3 losses, regardless of tillage system. UNBPT reduced the mean N-NH3 loss by 33% compared to PU. UNBPT (1,200 mg kg-1) and UNBPT (180 mg kg-1) reduced by 72% and 22% the N-NH3 losses compared to PU in the NT system.
