Question

Briefly explain the advantages of crop rotation with the help of examples.

Answer 1

If the same types of crops are grown, in the same field year after year, there will be depletion of particular nutrients from the soil. Thus, crop rotation is used where various crops are grown in rotation one after the other.

The advantages of crop rotation are as follows:

A. For example, if pulses or any leguminous crop is sown after cereal crops, they have the ability to fix nitrogen to the soil from the atmosphere. Similarly, oilseeds help in nitrogen fixation.

B. Crop rotation is also necessary to cultivate the land in such a way so that land resources and labour forces are used more efficiently and to use scarce water resources more judiciously in any climates.
