Answer 2

Answer:

The five methods of soil conservation are as follows :

• Mulching
• Contour barriers
• Rock dam
• Terrace farming
• Intercropping

• Mulching :

The bare ground between plants is covered with a layer of organic matter like straw. It helps to retain soil moisture.

• Contour barriers :

Stones, grass, soil, are used to build barriers along contours. Trenches are made in front of the barriers to collect water.

• Rock dam :

Rocks are pilled up to slow down the flow of water. This prevents gullies and further soil loss.

• Terrace farming :

Broad flat steps or terraces are made on the steep slopes so that flat surfaces are available to grow crops. They reduce surface run-off and soil errosion.

• Intercropping :

Different crops are grown in alternate rows and are sown at different times to protect the soil from rain wash.
