Soil erosion has been around since man first set foot on Earth.
Soil erosion is the physical process of wind or water picking up and removing soil particles.
Erosion involves the breakdown of the soil's aggregate structure and the selective removal of clay and humus. Water erosion is one type of erosion that occurs. About 3.5 tons of soil, per acre is lost to cultivated row-crop agriculture, such as corn. One kind of water erosion is splash erosion. Splash erosion is the effect of raindrops splashing against bare soil.
