Effects of conservation tillage on soil water regimes in rainfed areas
不同保护性耕作措施对旱作农田土壤水分的影响

Low and extremely variable precipitations limit dryland crop production in the semi-arid areas of the Loess Plateau. These areas are also affected by serious soil erosion, and intensive tillage of conventional agriculture has worsened the situation.
