Question

describe the following methods of soil conservation
1.contour ploughing
2.Terrace cltivation

Answer 1

Contour farming is planting of trees along the contours of sloping lands to minimise erosion and runoff. This method is especially suitable in the deforested areas.
Terracing reduces erosion and runoff on denuded slopes. It is especially suitable in hilly areas.

Answer 2

Terrace cultivation involves the construction of banks along the contours across the hill slopes

Contour ploughing is the cultivation of land along the contours in order to check the flow of water, which otherwise can wash away the soil.
