$\bold\pink{Question}$

List out any seven methods which can help in conservation of soil.

$\bold\red{Answer:-}$

Some methods of soil conservation are:-

1. $\bold\green{Mulching:-}$ The bare ground between plants is covered with a layer of organic matter like straw. It helps to retain soil moisture.

2. $\bold\green{Contour\:barriers:-}$ Stones, grass, soil are used to build barriers along contours. Trenches are made in front of the barriers to collect water.

3. $\bold\green{Rock\:dam:-}$ Rocks are piled up to slow down the flow of water. This prevents gullies and further soil loss.

4. $\bold\green{Terrace\:farming:-}$ 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. $\bold\green{Intercropping:-}$ Different crops are grown in alternate rows and are sown at different times to protect the soil from rain wash.

6. $\bold\green{Contour\:ploughing:-}$ Ploughing parallel to the contours of a hill slope to form a natural barrier for water to flow down the slope.

7. $\bold\green{Shelter\:belts:-}$ In the coastal and dry regions, rows of trees are planted to check the wind movement to protect soil cover.
