Some microorganisms such as nitrogen fixing bacteria, cyanobacteria, fungi and other microflora harbour near the roots of plant inside soil. They convert nitrogen of the air into nitrogenous compounds (ammonia and nitrate) which serve as plant nutrients. Since these microorganisms enrich the soil with nutrients and improve soil fertility, hence also collectively known as biofertilisers.
To get the maximum benefit from a crop field, we should (i) maintain the soil fertility through judicious use of manure and fertilizers. (ii) practise crop rotation. (iii) employ mixed cropping and intercropping method of agriculture. (iv) keep the weeds and insect pest population under control.
