List out any seven methods which can help in conservation of soil.
[tex]\bold\red{Answer:-}[/tex]
Some methods of soil conservation are:-
1. [tex]\bold\green{Mulching:-}[/tex] The bare ground between plants is covered with a layer of organic matter like straw. It helps to retain soil moisture.
2. [tex]\bold\green{Contour\:barriers:-}[/tex] Stones, grass, soil are used to build barriers along contours. Trenches are made in front of the barriers to collect water.
3. [tex]\bold\green{Rock\:dam:-}[/tex] Rocks are piled up to slow down the flow of water. This prevents gullies and further soil loss.
4. [tex]\bold\green{Terrace\:farming:-}[/tex] 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. [tex]\bold\green{Intercropping:-}[/tex] Different crops are grown in alternate rows and are sown at different times to protect the soil from rain wash.
6. [tex]\bold\green{Contour\:ploughing:-}[/tex] Ploughing parallel to the contours of a hill slope to form a natural barrier for water to flow down the slope.
7. [tex]\bold\green{Shelter\:belts:-}[/tex] In the coastal and dry regions, rows of trees are planted to check the wind movement to protect soil cover.
