Abstract
Agro-hydrological models can not only be used to study water dynamics in the soil-crop system, but also be used for agricultural water management. Therefore, it is important to devise this kind of models. In this study, a new agro-hydrological model, based on the compensatory root water uptake approach, was proposed. A dataset from field experiments on cabbage was used to evaluate the reliability of the model. Results showed that the predicted soil water potential at various depths agreed well with the measurements. The Nash-Sutcliffe efficiency coefficient and the Willmott’s index of agreement reached to 0.633 and 0.916, respectively, indicating that model was accurately constructed, and could potentially be used for optimizing water use in agriculture.
