Question

what is soil erosion what are the causes of soil erosion how can soil erosion prevent

Answer 1

Answer:

Crop Rotation: Rotating in high-residue crops — such as corn, hay, and small grain — can reduce erosion as the layer of residue protects topsoil from being carried away by wind and water. Conservation Tillage: Conventional tillage produces a smooth surface that leaves soil vulnerable to erosion.

Answer 2

Soil erosion:

Soil is an important natural resource. It is often carried away by strong winds or washed away by rain water. The removal of top soil by winds and water is called Soil erosion.

Cause of soil erosion:

1. Felling of trees (Deforestation), which makes the soil loose.
2. Heavy rains or floods, which wash away the top soil with force.
3. Overgrazing by animals also cause soil erosion.
4. Forest fires, which destroy plants and trees.
5. Poor farming methods cause soil erosion.

Prevention of soil erosion:

Prevention of soil erosion is also called Soil conservation.

Few methods to prevent or conserve soil :

1. Afforestation or planting of trees can prevent soil erosion.
2. Dams can be constructed and can be prevent soil erosion.
3. Planting trees as shelter belts to reduce the effect of strong winds.
4. Terrace farming on the slopes of hills to check soil erosion.
5. Preventing overgrazing also reduce soil erosion.
