What does “Biofertilisers” actually mean in Microbes in Human Welfare, and why does it matter for NEET?
living microbes like Rhizobium and cyanobacteria enrich soil naturally by fixing atmospheric nitrogen.
In simple words: living microbes like Rhizobium and cyanobacteria enrich soil naturally by fixing atmospheric nitrogen. Getting Biofertilisers clear matters because NEET questions on Microbes in Human Welfare usually test this idea directly, not just a formula you memorised.
