Role of Microbes in Soil Health Improvement

Abstract

Interaction, whether mutualistic, symbiotic or suppressive, that coexist in soil ecosystem within the plants, microbes or microfauna, is the most important phenomenon which regulates the soil health, vis-à-vis the plant health. The most intense interaction between microbes and plants takes place at the rhizosphere, where complex biological and biochemical activities between microbes, microbes-microbes, plant and plants-plants are always going on, to influence the biodiversity of beneficial organisms, supppression of pathogenic microflora and physio-chemical behavior of soil. Microorganisms appears to be the excellent indicators of soil health, as they respond quickly to changes in soil ecosystem and have intimate relations with the surroundings, owing to their high surface to volume ratio. The useful microorganisms can be exploited for the improvement of soil health, since they are involved in many soil processes.
