What is soil erosion? State the measures to prevent it.

Answer»

Soil Erosion: When land particles get transferred from one place to another due to fast-moving air i.e. wind and water, it is called soil erosion.

It takes many years to form the upper layer of soil. When this top layer of soil erodes due to heavy rain or by stormy wind, the agricultural production on that soil decreases. Hence, it is extremely important to check that the soil does not erode. Measures to prevent soil erosion:

  1. Control grazing activity on the land.
  2. Plantation should be carried out in contour method in sloppy regions.
  3. Trees should be planted in fallow land.
  4. Construct check dams on streams.
  5. To reduce the speed of the water cultivation should be done very deeply in the fields.
