The characteristics of overland flow under varied tillage and cropping systems in Sichuan Basin, China

Data from runoff plots operated over a five year period show that significantly less overland flow is generated with a seasonal no-till ridge system than with contour tillage or straight tillage systems. Seasonal no-till ridge is the optimum system for increasing the availability of water for rainfed agriculture on the dryland soils in the hilly area of Sichuan Province, China.
