Question

Essential elements that enhance plant growth are naturally available in soil through which of the following means?

• A. By the addition of chemical fertilisers.
• B. By microbial decomposition of plants/animals.
• C. By the addition of chemical pesticides.
• D. All of the above.

Answer 1

The correct option is B

By microbial decomposition of plants/animals.

Essential elements are naturally available in soil through the decomposition of plants/animals by microorganisms. The addition of chemical fertilisers is not a natural method and eventually depletes the quality of the soil. The addition of pesticides is to control pests and does not increase the fertility of the soil.
