Soil erosion leads to a lack of effective accumulation of organic matter in the soil, which reduces the fertility of the soil, and the fertility of unvegetated slopes is greatly reduced when they are washed away by heavy rains. In addition, soil erosion can have a series of negative effects on the physical and chemical properties of the soil and the agricultural ecology. “Soil erosion destroys the original structure of the soil, causing the surface layer to harden and microbial activity to become difficult, which can affect the growth […]
