Developing a water and nitrogen management model for greenhouse vegetable production in China: Sensitivity analysis and evaluation

摘要

Graphical abstractDisplay OmittedHighlights?A greenhouse vegetable water and N management tool was developed.?The sensitivity analysis of the model was conducted base on PEST methods.?The input parameters were auto-calibrated by coupling PEST.?The model performed well in modeling water and N fates, and vegetable growth.AbstractExcessive water and fertilizer inputs have led to a series of environmental problems in vegetable production areas in China. Identifying the fates of water and nutrients is crucial to develop best management strategies in intensive vegetable production systems. The objectives o
