The growing of different varieties of crops in succession on a piece of land to avoid ‘exhausting the soil and to control weeds, pests & diseases is called crop rotation.


Crop rotation is necessary for India as :

  1. It helps make the soil more fertile, as legumes such as beans and groundnuts fix nitrogen in the soil.
  2. It helps to reduce the use of chemical fertilizers as nitrogen is fixed naturally in the soil.
  3. It helps to control weeds, diseases, and pests by breaking their life cycles.
  4. It reduces the risk of crop failure in case of drought or diseases.
