Soil organic matter (SOM) can be defined as organic materials found in soil that are, or have been, part of living organisms. It is a continuum of materials at various stages of transformation due to biotic and abiotic processes. Despite its low concentration in soil, organic matter is of major qualitative importance.

Soil organic matter (SOM) is a complex, naturally occurring material and plays a critical role in soil fertility, the global carbon cycle, and the fate of pollutants in soil. Nuclear magnetic resonance (NMR) spectroscopy is one of the most powerful structural elucidation tools available and has played a quintessential role in unraveling the complex chemistry of SOM.

Soil organic matter (SOM) is the organic matter component of soil, consisting of plant and animal detritus at various stages of decomposition, cells and tissues of soil microbes, and substances that soil microbes synthesize. SOM provides numerous benefits to soil's physical and chemical properties and its capacity to provide regulatory ...

Nov 25, 2021 · Soil organic matter is comprised of both living and non-living components. The living component includes soil macro- and micro-fauna, and soil microbial communities, which may be active or dormant. The non-living portion of soil organic matter is derived from dead plant and faunal inputs into the soil (Figure 3.1).
Organic matter adds to soil fertility and overall soil health by enhancing the physical, chemical, and biological properties of soil. Soil organic matter: *Nitrogen (N), phosphorus (P), sulphur (S). It also adsorbs and stores other nutrients such as potassium (K), calcium (Ca), magnesium (Mg), copper (Cu), zinc (Zn).

How does organic matter affect soil formation?
Basically, it is the material in soil that is derived from living organisms, whether it is a carcass, waste product or other substance released from living organisms. Even though microbial cells are alive, they experience rapid population turnover — much like dead residues — and often are included in the definition of soil organic matter.
