The soil is a living entity and its significance and functions are irrefutable. Organisms present in the soil play a major role in sustainable soil health management. Current agrochemical-based nutrient management strategies can fulfil the demand of food to feed 7.8 billion humans living on earth, however, potential uses of agriculturally important microbial bioresources have been ignored, which can lead to compromise towards soil health and agro ecosystem sustainability. Major soil functions like nutrient and organic matter recycling, fertility, soil reclamation and ultimately tiny soil creatures called microbes, which comprise major portion of soil biota, manage soil and ecosystem health management. ABMs (Agriculturally beneficial microbes) include bacteria, actinobacteria, fungi and others which live in a mutualistic relationship along with plants (symbiotic/associative/free living/ endophytic) and make the nutrients available, play a major role in organic matter decomposition, produce phyto-hormones, phytoremediation and act as biocontrol agents for plant pests and diseases. These ABMs are supposed to be present in the soil, but looking to the sustainability and soil health, to enhance nutrient use efficiency, it is desirable to elevate their strength through direct application or following different agronomic interventions that enhance their abundance and activity. This review details the role of rhizospheric microorganisms and soil organic matter in soil quality management. |
