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 :

- It helps to reduce the use of chemical fertilizers as nitrogen is fixed naturally in the soil.
