Soil erosion decreases soil fertility, which can negatively affect crop yields. It also sends soil-laden water downstream, which can create heavy layers of sediment that prevent streams and...
Soil erosion involves a gradual wearing away of the soil surface, rocks, and pebbles. This movement in turn removes most of the organic matter and key nutrients from the soil. Consequently, the soil quality is degraded, crop yields are reduced, and the rooting depth of plants and crops is decreased. [2]
19 Οκτ 2006 · Soil erosion causes the decay of high organic matter and nutrients, insufficient food supply, the decay of edaphic properties, fertility, and soil life, increased surface runoff, and...
