Soil and water losses on red soil orchard slopes treated by eight different conservation treatments were assessed. There were significant different effects among these methods. Planting Bahia grass on level bench terrace ridge was the most effective method to preserve soil and water. Compared with bare soil (check), the average runoff ratio is reduced by 97.14% and the dry soil losses decreased by 100% on the grassing surface. Other methods also resulted in some positive effects. It is suggested that growing Bahia grass on orchard slope will improve vegetation coverage and soil conservation.
