A field experiment was conducted in the Qingshuihe County of Inner Mongolia to study the soil erosion of rain-fed cropland under effects of different
tillage modes, which would be of significance to the construction of ecological agriculture in the hilly regions of Inner Mongolia. Three treatments, i.e., no-tillage (NT), no-tillage with straw mulch (NS), and conventional tillage (CT), were installed, and the test crops were Sesamum indicum and Avena fatua. The annual precipitation, runoff, and soil loss were measured. Compared with CT, treatments NT and NS could markedly reduce soil erosion, e.g., the runoff and soil loss in treatment NS were decreased by 21.9% and 88.3%, respectively. Topography had great effects on soil erosion. In general, the soil erosion was increased with increasing gradient. Under the same topographic condition, the soil erosion differed with crop species. The relationships between precipitation and soil loss under the three tillage modes fitted power function, with R2>0.9.
