Soil Erosion which is also called as Corrosion of soil is a process due to which the soil, rock, wreck, etc, of the earth’s surface loosens and is dragged away which is described as the “wearing away” of the land. When there is rainfall on soft ground, streams and rivers can be seen carrying thick mud with them. The wind carries sand and dust from one place to another.
Running water of rivers can swoop the clay from its banks. Currents of river water are very strong, they grind stones, reduce rocks to sand and sand to finer sand while flowing. The water carry all the rubble with them to give them away to the sea.
Rivers and streams give rise to beautiful waterfalls, valleys, and can produce wonders like the Grand Canyon of Arizona. But erosion is considered as immense burden to human beings because it also removes the fertile topsoil, changes the course of river waters, and may destroy farms, forests and man-made constructions.

In primitive age, much erosion was done by glacier regions having low rainfall and dry seasons. These regions suffer because their soil becomes dry and dusty which is easily blown away by the wind if the land has no vegetation. One of the worst cases of this kind of wind erosion took place in mid-western states of the U.S.A. in the year 1930. It left the area devastated which is called the “Dust Bowl”.

Scientists and agricultural experts studying soil and their problems tell us that by deforestation, especially on the higher slopes or mountains, can result in immediate soil erosion which can destroy the lowland or farmland seriously.
One should take the opinion of farming with soil scientists before vegetation because they guide peasants to help reduce soil erosion and improve soil conservation.
