Question

Define soil erosion. Give its causes, effects and preventive measures?

Accepted Answer

Soil erosion is the removal of the topmost layer of soil from its original place to another place in the presence of erosive agents like strong winds, rainwater, etc.

The main cause of soil erosion are as follows:

Strong winds: The topmost layer of the soil is washed away when the strong winds are blown.

Heavy rains: When rain falls on the uncovered and loose soil, soil is eroded.

There are some following effects of soil erosion, which are as follows:

Soil erosion leads to the loss of soil fertility and desertification.

Soil erosion leads to the silting of water reservoirs.

Preventive measures of soil erosion:

Intensive cropping: If the farms remain covered with vegetation throughout the year, their topsoil will not be subjected to wind or rain, so there will be no soil erosion.

Contour bunding: Small bunds are raised on the edges of fields to prevent soil erosion by wind or water.

Conservation tillage: By reducing the use of tillage, soil erosion can be prevented.

Windbreaks: Soil erosion can be prevented by planting the plants and shrubs at the right angle.
