7693. Yan, Ying. 1989. A model for predicting soil loss ratio and crop production in eastern Washington. M.S. Thesis, Dept. of Agronomy and Soils, WSU, Pullman, WA.
The model (SHUI) predicts soil erosion and crop production under different crop rotation, tillage operation, and crop residue management conditions. It simulates the soil-water budget, crop and root growth, top dry matter production, grain yield, and residue production and loss, and predicts the soil loss ratio. Validation data are included.
