Crops need nutrients to grow, which they readily take from the soil. However, each crop is different; It may depend on certain specific nutrients for it growth, which it would take from the soil in large quantities, Hence, after repeated growth of the same crop on the soil, the soil may get depleted of some of its essential nutrients and may no longer be able to support the growth of the plant.
Crop rotation is a method of growing different crops alternatively, in the same field in a successive season. For example, growing pulses in one season and legumes in next season.
