Answer:

Field fallow, crop rotation and mixed cropping are three natural methods of replenishing the nutrients of the soil. These natural methods are not enough and farmers have to resort to manures and fertilisers.

 (i) Kharif crops- The crops which are sown in the rainy season are called kharif crops. Example- paddy, maize. (ii) Rabi crops – The crops grown in winter season are called rabi crops.

The modern methods of irrigation include – surface irrigation, drip irrigation, sprinkler irrigation, subsurface irrigation.
