Explain the ways to conserve soil.
Ways to conserve soil are :
- Terrace farming: These are made on the steep slopes so that flat surfaces are available to grow crops. They can reduce surface run-off and soil erosion.
- Contour ploughing: Ploughing parallel to the contours of a hill slope to form a natural barrier for water to decelerate flow of water down the slopes.
- Strip cropping: Large fields can be divided into strips. Strips of grass are left to grow between the crops to break up the force in the wind.
- Shelter belts: In the coastal and dry regions, rows of trees are planted to check the wind movement to protect soil cover.
