Question

Which of the following methods of cultivation will result in the loss of soil fertility?
I.Crop rotation
II. Inter-cropping
III. Excessive use of chemical fertilizers

• A. I and II only
• B. III only
• C. I and III only
• D. I, II and Ill

Answer 1

Answer: (B)

III only

When there is excessive use of chemical fertilizers and pesticides, the chemical salts accumulate in the soil and affect the quality and fertility of the soil.

Crop rotation (growing of different crops on a piece of land in pre-planned succession) and inter-cropping (growing two or more crops in definite row patterns) methods are types of cropping patterns that are used to maintain the fertility of the soil.

Thus, the correct answer is option B.
