3 days ago · Detritus is also known as active soil matter, and is composed of dead plants and animals that are actively decomposing. Fallen leaves, dead flowers, and deceased animals all contribute to the formation of detritus, but that's only the first step in forming the organic materials in our soil. The other kind of organic material in soil is humus.
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.
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.

Aug 19, 2024 · In this article, I’m going to describe the differences between organic and non-organic soil. In this context, organic means materials from living organisms. Organic soil is often used to describe soil that has no chemical additives, but the USDA does not regulate how soil is labeled.
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.
