explain the method to check soil erosion
Answers
Answer:
Different methods to check soil erosion are:
(i) Control overgrazing by livestock- Cattle, sheep, goats and other livestock tear up roots from the soil and ruining the texture and leave the land barren and exposed to wind and rain.
(ii) Mixed Cropping- it involves growing a variety of crops, mixed together. It is sown in rows or in regular intervals to prevent the soil from erosion.
(iii) Plant trees- Planting trees help to break wind and guard the soil against erosion. It also binds the soil with its deep roots and regulates the climate of a place by bringing sufficient rainfall.
(iv) Terracing- Terraces are built on steep slopes to control soil erosion. It levels the soil and supports are built to prevent landslides. It requires skill and hard labour to build it.
(v) Ploughing of Contours- It involves ploughing the land along the contour line to protects the soil from surface run-off by water.
