Why crop rotation is considered a good agricultural practice?

Crop rotation is a technique of growing different crops on the same field in a pre-planned succession. Soil loses its fertility if the same crops are grown repeatedly. Hence, it is necessary to do crop rotation. Crop rotation can either be a one, two or a three-year rotation.

Some advantages of crop rotation include-

1. Reduces crop failure.

2. Increases the variety of crops grown.

3. Increases soil fertility.

4. Prevents soil erosion.

5. Replenishes soil nutrients.

6. Reduces crop infections.
