The National Soil Erosion Research Laboratory
Soil erosion is the detachment and movement of soil particles by the
erosive forces of wind or water. Soil detached and transported away from
one location is often deposited
at some other place. While soil erosion can be controlled, it is almost
impossible to completely stop.
In 1987, it was estimated that about 3.9 billion metric tons of soil are lost each year through the processes of wind and water erosion. About 70% of the total is eroded from agricultural land.
Types of soil erosion:
Soil erosion can be classified into several forms including interrill, rill, sheet, gully and landslides.
