List out any seven methods which can help in conservation of soil.
Some methods of soil conservation are:-
1. The bare ground between plants is covered with a layer of organic matter like straw. It helps to retain soil moisture.
2. Stones, grass, soil are used to build barriers along contours. Trenches are made in front of the barriers to collect water.
3. Rocks are piled up to slow down the flow of water. This prevents gullies and further soil loss.
4. Broad flat steps for terraces are made on the steep slopes so that flat surfaces are available to grow crops. They reduce surface runoff and soil erosion.
5. Different crops are grown in alternate rows and are sown at different times to protect the soil from rain wash.
6. Ploughing parallel to the contours of a hill slope to form a natural barrier for water to flow down the slope.
7. In the coastal and dry regions, rows of trees are planted to check the wind movement to protect soil cover.
