Abstract:

To address the issue of soil erosion on sloping farmland with thin soils in the earth-rocky mountainous area of north China, we established standard runoff plots to investigate the comprehensive soil and water conservation effectiveness of stone-sill reverse-slope terraces. Our findings revealed a significant control effect on water and soil loss: runoff and sediment were reduced by 68.57% and 94.29%, respectively, compared to contour farming. Stone-sill reverse-slope terraces effectively increased soil moisture content and ensured a more uniform distribution of water across the slopes. The total soil moisture content increased by 7.78% compared to contour farming plots. Additionally, the stone-sill reverse-slope terraces markedly enhanced crop yields on sloping farmland; corn yields increased by 12.69% compared to contour farming. Our design and study of the stone-sill reverse-slope terrace contribute to the soil and water conservation methods for thin-soiled sloping farmland in north China’s earth-rocky mountainous areas.

Key words: stone-sill reverse-slope terrace, sloping farmland with thin soil layer, soil and water loss, earthy-rocky mountainous areas of north China, runoff, soil moisture
