What is the main purpose of mulching in agriculture?
A. To increase soil erosion B. To conserve soil moisture C. To decrease soil fertility D. To promote weed growth E. To reduce crop yield
Correct Answer: B
Explanation
Mulching involves covering the soil surface with a layer of organic or inorganic materials such as straw, leaves, plastic, or rocks. The primary purpose of mulching in agriculture is to conserve soil moisture by reducing evaporation, suppressing weed growth, regulating soil temperature, and preventing erosion. Mulch also adds organic matter to the soil as it decomposes, improving soil structure and fertility.
