   What is soil organic matter?

   • Jingzhe Wang, ... Xiaodong Yang, in International Soil and Water Conservation Research, 2023 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).

   Does soil have a high organic matter content?

   • However, it is important to know that although the soil might appear to have a high organic matter content, this is not completely true. Of more importance is the active soil organic matter, which has already been decomposed to some degree and actively contributes to the soil properties, such as in CEC and physical aggregation.

   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.

   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.

   Are soil organic carbon and soil organic matter the same quantity?

   • Soil organic carbon (SOC) and soil organic matter (SOM) are not the same quantity. It has, however, become an automatic practice to convert between SOC and SOM using Equation 3: This assumes that carbon molecules comprise 58% of the total mass of soil organic matter.
