Question

Soil conservation is achieved through

• A. Restricted human activities
• B. Good plant cover
• C. Wind screen
• D. Ploughing

Answer 1

The correct option is B Good plant cover

Soil erosion is removal of top soil by agency of water (water erosion) and wind (wind erosion). Soil erosion is of two types- natural and anthropogenic.

Natural or geological erosion is extremely slow removal of top soil due to rain water or wind.

Anthropogenic soil erosion is caused by removal of plant cover through over grazing, tree felling, leaving the soil unprotected during agricultural operations.

Thus, soil conservation can be achieved through good plant cover.
