What is the importance of microorganism in soil?

Microorganisms play foremost role in soil formation and soil ecology because they as ‘natural soil engineers’ regulate the flux of nutrients to plants and prop up nitrogen fixation, and ultimately promote detoxification of naturally occurring inorganic and organic pollutants in soil.
