Soil erosion is of great concern in every agricultural region of the world due to its long-term negative effects on soil productivity. Northeast China, the grain production base of China, or the bread basket of China is not an exception and also faces the same environmental issue. Over-reclamation and improper management of these soils resulted in severe soil degradation and this has threatened the soil productivity potential in this region. The trend of soil erosion in Northeast China illustrates that the eroded area is increasing, gulley frequency and size are increasing, top soil is thinning and sediment deposition is increasing. In response to these conditions, contour tillage, earth bank and level bench terraces were used to slow overland surface water flow and increase water infiltration time. No-till, basin-till and zonal-till are also applied to control soil erosion. Using these measure, have had a positive soil conservation effect in Northeast China. This may provide valuable information to support soil erosion control for other similar Mollisol regions.
