Question
Elaborate the methods of soil conservation.
✓
Answer
Some methods of soil conservation are:
Mulching- The bare ground between plants is covered with a layer of organic matter like straw. It helps to retain soil moisture.
Rock Dams- Rocks are piled up to slow down the flow of water. This prevents gullies and further soil loss.
Intercropping- Different crops are grown in alternate rows and are sown at different times to protect the soil from rain wash.
Shelter belts- Rows of trees are planted to check the wind movements to protect soil cover.
Contour barriers- Stones, grass and soil are used to build barriers along contours. Trenches are made in front of them to collect water.
Terrace farming- Broad flat steps or terraces are made on the steep slopes so that flat surfaces are available to grow crop. It reduces the surface runoff and soil erosion.
Contour ploughing- Ploughing parallel to the contours of a hill slope to form a natural barrier for water to flow down the slope.
