Nitrate leaching losses from arable land can negatively impact ground water quality. Prediction of nitrate leaching with agricultural system model is helpful to manage the crop land for reduction of nitrate leaching. In this study, APEX (Agricultural Policy Environmental eXtender) model was evaluated for simulating the nitrate leaching potential in agricultural land. The model for nitrate leaching prediction was calibrated and validated with the data from the lysimeter in National institute of agricultural science, Rural development administration. The nitrate-N leaching during cropping season of soybean (Jun to October) and Chinese cabbage (September to October) in lysimeter was simulated from 1986 to 2015 with the adjusted model. The measured (x) and simulated (y) total nitrate-N leaching that was accumulated during cropping period in lysimeter was significantly correlated (n = 9, y = 0.9275x, R² = 0.948). The range of total nitrate-N leaching according to soybean and Chinese cabbage cultivation was 0 - 4 ㎏ ㏊<SUP>-1</SUP> and 3.8 - 11.6 ㎏ ㏊<SUP>-1</SUP>, respectively. Thus, we confirmed the APEX model reflects differences in nitrate leaching potential under the different types of crop and fertilization. These results suggest that APEX model can be successfully used in estimating nitrate leaching of arable land.
