www.nrcs.usda.govSoil organic matter (SOM) is the organic component of soil, consisting of three primary parts including small (fresh) plant residues and small living soil organisms, decomposing (active) organic matter, and stable organic matter (humus). Soil organic matter serves as a reservoir of nutrients for crops, provides soil aggregation,

Cation Exchange Capacity (CEC)
nmsp.cals.cornell.eduOrganic matter can have a 4 to 50 times higher CEC per given weight than clay. The source of negative charge in organic matter is different from that of clay minerals; the dissociation (separation into smaller units) of organic acids causes a net negative charge in soil organic matter, and again this negative
Basic Soil Science
www.dcr.virginia.govSoil Organic Matter Humus is the dark brown to black complex decomposition product of organic matter turnover in soils. It is colloidal, much more highly charged than clay on a weight basis, and is typically what we report as organic matter content in soil testing programs.
What is Organic Farming?

It is important to remember, however, that using too much animal manure or nutrient rich organic matter, or using it at the wrong time, could be as harmful as using man-made, artificial fertilisers.
Wastewater Technology Fact Sheet: Trickling Filters
www3.epa.govTrickling filters (TFs) are used to remove organic matter from wastewater. The TF is an aerobic treatment system that utilizes microorganisms attached to a medium to remove organic matter from wastewater. This type of system is common to a number of technologies such as rotating biological contactors and packed bed reactors (bio-towers).

The process consists of delivering clarified waste-water, after primary settling, into an aeration basin where it is mixed with an active mass of microorganisms, mainly bacteria and protozoa, which aerobically degrade organic matter into carbon dioxide, water, new cells, and other end products.

Humus farming made little or no use of soluble commercial fertilizers or pesticides, in part because the health of the soil rendered them unnecessary.

The sludge is taken to the bottom of the pond by the sedimentation process. These types of ponds are usually 2-5 meters deep and receive an organic load of >100 g BOD/m³d equivalent to >3000 kg/ha/d for a depth of 3 meters.
