Question

Which of the following can help in enriching the fertility of the soil?

• A. Reuse of land
• B. Crop rotation
• C. Tilling
• D. Cutting of trees

Answer 1

The correct option is B Crop rotation

Crop rotation is the process of growing different types of crops in the same area one after the other. If the same type of crop is planted one after the other, the soil gets deprived of a single nutrient. The process of crop rotation avoids this situation and maintains all the nutrients in the soil. It uses grain legumes which enhances the soil fertility through biological nitrogen fixation.So, the answer is B.
