Contour bunding is a method of soil conservation used in

The correct answer is  None of the above

 Key PointsCONTOUR BUNDING:

1. This method of soil and water conservation is employed in hilly areas.
2. Earthen embankments are built across the slope of the land, following the contour as close as possible.
3. This helps in reducing the flow of water down the slope.

Some common methods of preventing soil erosion are:

1. Shelterbelts - in this, trees and shrubs are planted in the areas liable to strong wind action, to shield the fields against winds.
2. Terracing - this is also practiced in the sloppy areas.
3. Perimeter runoff control - it helps in preventing soil erosion by impeding surface flows.
4. Mixed cropping and crop rotation also help in soil conservation by preventing the nutrients from getting eroded.
