Answer:
Crop management: proper crop management is essential as it reduces the chances of soil infertility.
• Terrace farming: this is the a mechanical way of conserving soil in hilly or mountainous region.
• Avoid deforestation: deforestation is the major reason for the soil erosion thus washing off the upper fertile layer of the soil.
The three methods are used for soil conservation:
Terrace cropping: The cultivation of steps or terraces on the slopes restricts erosion. The Western Himalayas and Central Himalayas have a well-developed terrace.
Strip cropping: Here you can divide large fields into strips. Strips of grass between the crops are left to grow. The grass can be left out after harvesting results in order to increase the fertility of the soil.
Shelterbelt planting: These shelterbelts help in stabilizing the sand dunes. The sand dunes are the main reason for soil erosion. The shelterbelt planting tightens the soil and reduces erosion
