उत्तर
Organisms that increase the nutrient content of the soil are called as bio-fertilisers. They are nitrogen-fixing microorganisms used for specific crop plants such as pulses, legumes, oil seeds, and rice. They can play a supplementary role in supplying nitrogen to specific crops under specific soil conditions. They do not pollute and can be renewed.
Example: Rhizobium is a bio-fertiliser used by farmers who grow pulses, legumes, etc.
