   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 is soil organic matter?

   • Organic matter is essentially the heart of the story, but, as we will discuss later, certainly not the only part. In addition to functioning in a large number of key roles that promote soil processes and crop growth, soil organic matter is a critical part of a number of global and regional cycles.

   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 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.

   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.

   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.
