Soil organic matter (SOM) is the organic matter component of soil. It can be divided into three general pools: living biomass of microorganisms, fresh and partially decomposed residues, and humus: the well-decomposed organic matter and highly stable organic material. Surface litter is generally not included as part of soil organic matter. [1][2]
Humus
In stable soils, humus dominates the soil organic matter fraction. Thus most of the benefits and properties of soil organic matter relate specifically to humus.
