Definition: Soil microbial biomass is the living component of soil organic matter excluding soil animals and plant roots larger than 5X10 3 µm 3 (Jenkinson and Ladd, 1981). Microbes and Soil Fertility Directly or indirectly, the wastes of man and other animals, their bodies, and the tissues of plants are dumped onto or buried in the soil. Soil oxygen levels often determine soil bacteria activity (Dick, W., 2009). 0000049957 00000 n Fertile soils teem with soil microbes.

ROLE OF ORGANIC MATTER AND HUMUS Increasing soil organic matter is a key aspect of an organic production system. Prospectives of Microbes in soil Bioremediation: Use of microbes to detoxify or degrade pollutants; enhanced by nitrogen and phosphorus fertilizer Bioaugmentation: Addition of specific microbes to facilitate degradation of pollutant Biostimulation: Practice of addition of nitrogen and phosphorus to stimulate indigenous microorganisms in soil. ��3�������R� `̊j��[�~ :� w���!
