Question

Soil conservation can be best achieved by having a

• A. Wind screens
• B. Good plant cover
• C. Restricted human activity
• D. Low rainfall

Answer 1

The correct option is B Good plant cover

Anthropogenic soil erosion is caused by removal of plant cover through over grazing, litter collection, tree felling, leaving the soil unprotected during agricultural operations. Anthropogenic factors remove green cover and expose the soil to natural agents of soil erosion i.e., water and wind. When rains fall, most of the top layer of soil is washed away, if the soil is not covered by vegetation.

Conservation of soil can best be achieved through good green cover over soil.
