Soil organisms: ... soil contains more species than above-ground in the entire Amazon rainforest. The role of organic matter in soil fertility BY E. W. RUSSELL Department of Soil Science, University of Reading Soil organic matter is a very heterogeneous mixture of substances, ranging from plant and root fragments, through the living bodies of the soil organisms, to brown amorphous humic substances produced by their activity. The disease caused by these pathogens are difficult to predict, detect, diagnose and successfully control.
