Text Solution

Verified by Experts

The correct Answer is:
B
Biofertilisers are microorganisms which bring about nutrient enrichment of soil by enhancing the avilability of nutrients to crops. Microorganisms which act as biofertilisers are bacteria, cyanobacteria (blue green algae) and mycorrhizal fungi. Bacteria and cyanobacteria have the property of nitrogen fixation while mycorrhizal fungi preferentially withdraw minerals from organic matter for the plant with which they are associated. They maximise ecological benefits and minimise environmental hazards.
