Jun 16, 2022 · Soil organic matter comes from the organic material from plants (e.g. leaves and woody materials), animals (e.g. decaying components), and microorganisms. The presence of organic matter in the soil is essential as a source of nutrients for crops and other garden plants.
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.
Soil is a material composed of five ingredients — minerals, soil organic matter, living organisms, gas, and water. Soil minerals are divided into three size classes — clay, silt, and...
Organic soils are soils primarily composed of organic matter such as decomposed plant and animal residues. They are typically found in wetlands or areas with poor drainage.
