PREVENTION OF SOIL EROSION
-
Reduction or prevention of soil erosion is called soil conservation.
-
The following are some of the measures that help in conserving soil:
-
Planting of trees in large numbers on deforested land (afforestation).
-
Grasses and herbs can be used to cover large patches of loose soil.
-
Overgrazing of a single patch by animals should be avoided.
-
Animals should be moved to a different area after some time.
-
Floods can be controlled to a large extent by building dams.
-
Embankment or mud walls should be constructed around hill slopes or fields to stop the flow of water.
-
Terrace farming should be adopted in hilly areas.
-
In this method, suitable crops are grown on sloping ground which is cut into large steps called terraces.
-
This reduces the speed with which water flows down, thereby reducing soil erosion.
