| Abstract: | Purpose In the semi-arid loess region of northwestern China, use of stone and gravel as mulch has been an indigenous farming technique
for improving crop production for over 300 years. However, systematic studies on the effects of stone covers on soil and water
conservation have been rarely conducted, except for a few investigations and documentations on the stone cover effects on
erosion and solute transport in such a highly erodible loess region. |
