* Labile (bio-available) source of C, N, P & S
* An immediate sink of C, N, P & S
* An agent of nutrient transformation and pesticide degradation
* Microorganisms form symbiotic associations with roots
* Contribute towards soil aggregation, and participate in soil formation
* Act as biological agents against plant pathogens
