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.
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 piled up to slow down the flow of water. This prevents gullies and further soil loss.
Terrace farming: These are made on the steep slopes so that flat surfaces are available to grow crops. They can reduce surface run-off and soil erosion.
Intercropping: Different crops are grown in alternate rows and are sown at different times to protect the soil from rain wash.
Contour ploughing: Ploughing parallel to the contours of a hill slope to form a natural barrier for water to flow down the slope.
Shelter belts: In the coastal and dry regions, rows of trees are planted to check the wind movement to protect soil cover.
