Soil erosion was simulated by three levels of soil desurfacing, 7.5, 18 and 30cm with threereplicates. Significant differences in crop height, ground cover and crop yield were observed between the threelevels of desurfacing. Soil desurfacing also has a significant effect on soil moisture at the 20cm depth. Theinteraction between soil removal and crop performance affected soil moisture at the depths of 50 and 100cm.No significant differences were found in runoff and sediment between the three topsoil removals due to verydry growing season. Regression equations were developed between spring barley yield and soil desurfacing.Spring barley grain yield declined by 97.6kg/ha per cm soil desurfacing.展开更多
