The effect of N fertilizer application in rice field on the environmental quality of ground-water was evaluated using large undisturbed monolith lysimeters. Soil in lysimeters was silty-clay-loamy paddy soil (Haplaquept) with a pH of 6.5, 15.4 g/kg organic C. 1.55 g/kg total N, 88 mg/kg available N, 399 mg/kg Alabbas-P, 67.5 mg/kg exchangeable K, and 14.1 cmol/kg CEC.
