Question

What are the methods used for soil replenishment?

• A. Addition of manure
• B. Keep land uncultivated
• C. Crop rotation
• D. All of these

Answer 1

The correct option is D

All of these

Replenishment of soil means enrichment of soil with nutrients required for the next crop. Addition of manure increases the nutrients in the soil. Keeping the land uncultivated (fallow) for some time allows soil to regain its nutrients from atmosphere. Crop rotation means changing the crops according to the nutrient requirements regularly which keeps the land fertile.
