Soil can best be conserved on the hills by which of the cultivating methods?
A
Strip cropping
B
Crop rotation
C
Contour ploughing
D
Terracing
Correct Answer: Contour ploughing
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.
