Explanation:
Soil can best be conserved on the hills by Contour ploughing. If ploughing is done at right angles to the hill slope, the ridges and furrows break the flow of water down the hill. This prevents excessive soil loss as gullies are less likely to develop and also reduce run-off so that plants receive more water.
