Question

explain any four ways by which soil can be conserved​

Answer 1

Answer:

Techniques for improved soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks, affect both erosion and fertility. When plants die, they decay and become part of the soil.

Explanation:

1. 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  

2. Contour ploughing: Ploughing parallel to the contours of a hill slope to form a natural barrier for water to flow down the slope.  

3. Shelter belts: In the coastal and dry regions, rows of trees are planted to check the wind movement to protect soil cover.  

4. Rock dam: Rocks are piled up to slow down the flow of water. This prevents gullies and further soil loss.
