How do biofertilisers enrich the fertility of the soil?
Bio-fertilizers
are living organisms which help in increasing the fertility of soil.
It involves the selection of beneficial micro-organisms that help in
improving plant growth through the supply of plant nutrients. These
are introduced to seeds, roots, or soil to mobilize the availability
of nutrients by their biological activity. Thus, they are extremely
beneficial in enriching the soil with organic nutrients. Many
species of bacteria and cyanobacteria have the ability to fix free
atmospheric nitrogen. Rhizobium is a symbiotic bacteria found
in the root nodules of leguminous plants. Azospirillium
and Azotobocter are free living nitrogen-fixing bacteria,
whereas Anabena, Nostoc, and Oscillitoria are examples
of nitrogen-fixing cyanobacteria. Bio-fertilizers are cost effective
and eco-friendly.
