How do Bio fertilisers enrich the fertility of soil? How do cyanobacteria act as biofertilizers?
Microorganisms employ biological channels to improve soil fertility for optimal crop development, and they are referred to as "BIOFERTILIZERS." These microorganisms can boost crop output in one of two ways. i) By removing nitrogen from the atmosphere ii) Insoluble fertiliser solubilization iii) By promoting the growth of plants. iv) Through phosphorus absorption. v) By allowing plant remnants to decompose. Anabaena, a cyanobacterium found in the leaf cavity of the water fern Azolla, fixes nitrogen from the air and excretes nitrogenous compounds into the leaf cavity.
