Question

What suggestion will you give a farmer to increase the productivity of his field? Explain.

Answer 1

A farmer can use biofertilisers to increase the productivity of his field. Biofertilisers are the microorganisms which are used for increasing fertility of the soil. This type of farming is known as organic farming. Biofertilisers provide optimum nutrients to crop plants. They enrich the nutrient quality of the soil. They do not cause any environmental pollution. The main sources of biofertilisers are bacteria, fungi and cyanobacteria.
