摘要: Fertilization rates of nitrogen (N) in rice crop are based on needs and the capacity soil to supply N, which is determined by several methods. This study evaluated a method anaerobic incubation without shaking for extended periods time. Three soils Inceptisol, Alfisol, Vertisol orders were fertilized with N 0, 80, 160 kg ha−1 incubated 7, 14, 21, 28 d at 20 40 °C. The methodology also used short-term constant 7 d Field experiments conducted same equal rates, extracted plant was compared mineralized N. Results indicated that comparable procedure incubations. However, incubations longer time had greatest relation
