Question

how do microbes increase fertility​

Answer 1

Answer:

Microorganisms such as bacteria and fungi play an important role in maintaining the soil fertility. Microbial action on dead organic matter releases nutrients in the soil thus raising the fertility status of the soil. Diazotrophic bacteria and cyanobacteria like Azotobacter, Bacillus, Beijerinckia, Clostridium, Klebsiella, Nostoc, Anabaena, Anabaenopsis, etc. raise the nitrogen status of soil by fixing atmospheric nitrogen. Moreover, phosphate solubilizing bacteria and fungi increase phosphorus availability to plants in the soil. Microorganisms also improve the soil structure which protects the soil against erosive forces.
