Introduction :
Soil erosion is a major global environmental problem. Soil erosion is natural process, occurring over geological time, and indeed it is a process that is essential for soil formation in the first place. The upper most weathered and disintegrated layer of the Earth’s crust is referred to as soil. Soil is the most precious gift of the nature to the mankind. By removing the most fertile top soil erosion reduces soil productivity.
