What's the difference between organic matter and organic matter?

The difference between organic matter and organic matter:

Organic matter (humus) generally refers to substances in soil that are derived from life. Organic matter is mainly composed of carbon and hydrogen, and it is a certain carbon-containing compound, but it does not include carbon oxides (carbon monoxide and carbon dioxide), carbonic acid, carbonate, cyanide, thiocyanate, cyanate, metal carbide and some simple carbon-containing compounds (such as SiC).

Organic matter (humus) generally refers to substances derived from life in soil, including soil microorganisms and soil animals and their secretions, as well as plant residues and plant secretions in soil. Organic matter has mineralization and humification. It is the main source of soil nutrients; Promote the formation of soil structure, improve soil physical properties, change soil porosity and improve soil water storage capacity; Increase soil fertility and improve soil buffering performance; Humus has physiological activity and can promote crop growth and development; Humus has complexing effect, which is helpful to eliminate soil pollution.

Organic matter is mainly composed of carbon and hydrogen, and it is a certain carbon-containing compound, but it does not include carbon oxides (carbon monoxide and carbon dioxide), carbonic acid, carbonate, cyanide, thiocyanate, metal carbides and some simple carbon-containing compounds (such as SiC). Organic matter is the material basis of life, and all living things contain organic matter. Fat, amino acids, protein, sugar, heme, chlorophyll, enzymes, hormones, etc. Both metabolism and genetic phenomena in organisms involve the transformation of organic compounds. In addition, many substances closely related to human life, such as oil, natural gas, cotton, dyes, chemical fibers, plastics, plexiglass, natural and synthetic drugs, are closely related to organic compounds.
