   Soil organic matter (SOM) is the organic matter content 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 (Brady & Weil, 2008).

   Soil organic matter is the key to building and maintaining healthy soils because it has such great positive influences on essentially all soil properties—aggregation, nutrient availability, soil tilth and water availability, biological diversity and so on— helping to grow healthier plants.

   What makes a soil rich in organic matter?

   • A soil rich in organic matter and continually supplied with different types of fresh residues, through the use of cover crops, complex rotations and applied organic materials such as compost or animal manure, is home to a much more diverse group of organisms than soil depleted of organic matter.

   Does soil organic matter contain hydrogen and oxygen?

   • Soil organic matter also contains hydrogen- and oxygen-containing functional groups, which contribute to the overall soil organic matter mass. While it also is assumed that hydrogen contributes ca. 4% and oxygen contributes ca. 30% to the overall composition, we know that this depends on the decomposition state of soil organic matter.

   What type of soil is organic?

   • Soils containing 12% to 18% SOC are generally classified as organic soils. SOM can be divided into three genera: the living biomass of microbes, fresh and partially decomposed detritus, and humus. Surface plant litter, i.e., fresh vegetal residue, is generally excluded from SOM.

   Why does organic matter persist in soils?

   • In addition to the interaction of organic matter with mineral surfaces, physical protection inside aggregates (Figure 3.4a) is considered to be an important mechanism for organic matter persistence (Six et al. 2002). In that case, organic matter mostly persists in soils because it is spatially separated from the decomposing microbial communities.

   Soil organic matter holds 10 to 1,000 times more water and nutrients than the same amount of soil minerals. Beneficial soil organisms become more numerous and active with diverse crop rotations and higher organic matter levels.
