Modeling Nitrate Leaching and Optimizing Water and Nitrogen Management under Irrigated Maize in Desert Oases in Northwestern China

摘要：

Understanding water and N transport through the soil profile is important for efficient irrigation and nutrient management to minimize nitrate leaching to the groundwater, and to promote agricultural sustainable development in desert oases.In this study, a process-based water and nitrogen management model (WNMM) was used to simulate soil water movement,nitrate transport, and crop growth (maize ”Zea mays L.”)under desert oasis conditions in northwestern China.The model was calibrated and validated with a field experiment.
