Question

How does the activity of each one of the following help in organic farming?
Cyanobacteria

Answer 1

Cyanobacteria are free-living or symbiotic blue-green algae which are capable of converting atmospheric molecular nitrogen into the soluble form like nitrites or nitrates.
This is called nitrogen fixation.
The cyanobacteria carry out this process when free-living in the soil or plant roots and enrich the nitrogen content of the soil acting as a natural fertilizer.
