Soil moisture is a key factor affecting the crop production in the Loess Plateau.Erosion Productivity Impact Calculator(EPIC) model has been widely applied to effectively simulate soil water throughout the world since it has been established.The long-term experimental data from forage-cereal rotation land(alfalfa-alfalfa-alfalfa-alfalfa-potato-winter wheat-winter wheat-winter wheat) was used to evaluate the accuracy of simulated soil water by EPIC model.This study showed that mean correlation coefficients b...
