Soil loss by water erosion

Figure 2. Potato dams in the downslope direction force soil loss by water.

Uncovered soils are exposed unprotected to the energy of water during heavy and prolonged rainfall. The water transports the soil irretrievably downhill. As a result, fertile soil is lost, and therefore the yielding capacity on arable land. In addition, the eroded material and the absorbed nutrients and pollutants can pollute neighboring water bodies.
