Question

which of these measures is useful in preventing soil erosion by water in hilly areas?​

Answer 1

Answer:

Contour Ploughing: If ploughing done at right angles to the hill slope, following the natural contours of the hill, the ridges and furrows break the flow of water down the hill. This will prevents soil erosion.

Answer 2

Answer:

The following are the important steps taken to control soil erosion in hilly areas:

1. Afforestation: The best way to conserve soil is to increase the area under forest. Indiscriminate felling of the trees should be stopped and efforts should be made to plant trees in new areas.

2. Checking shifting cultivation: Checking and reducing shifting cultivation will reduce soil erosion.

3. Contour Ploughing: If ploughing done at right angles to the hill slope, following the natural contours of the hill, the ridges and furrows break the flow of water down the hill. This will prevents soil erosion.
