Question

Which one of the following is not a method of soil conservation?

• A. Mulching
• B. Overgrazing
• C. Strip cropping
• D. Crop rotation

Answer 1

The correct option is B Overgrazing

Soil conservation is the process of prevention of soil erosion and preventing the soil from becoming infertile. In mulching, a protective layer is placed over the soil such as straw, grasses, etc., which helps in retaining soil moisture and also regulates soil temperature. Strip cropping is a process in which a field is divided into strips and different crops are grown in alternate strips to preserve soil fertility. Crop rotation means growing different types of crops on the same field in succession which prevents the depletion of nutrients from the soil. Overgrazing or intense grazing will erode the soil.

Thus, the correct answer is option B.
