The Story of Organic Matter Decay in Soils

Talk of Organic Spoilage in Soil For most people, humus is garlic chick peas for sandwiches and pita bread. But for soil scientists, that is quite different. Soil humus is a mixture of relatively dark colloidal organic compounds that are resistant to degradation. These compounds are derived from the disintegration of organic waste and accumulate in O layer and A layer of the soil. Soil humus binds mineral particles to aggregate, gives soil structure, and affects soil stability.

Organic matter in the soil is caused by spoilage of dead plants and animals.蚯蚓, bacteria and fungi are only a few creatures living in the soil, eating organic matter, decaying and recycling phytonutrient nutrients. All creatures in the soil are an important part of the natural process of decomposing organic matter and preparing the soil for future plant growth in the future. Among millions of creatures in one acre soil, earthworms are probably the most important large biota. The number of cockroaches ranges from hundreds to over a million per acre. They will digest organic matter and recover nutrients that can enrich the surface soil.

This life in the soil depends on the dead substance in the soil. Bacteria and fungi may be generated as long as organic matter is contained in the soil decaying plant or animal matter form. Soils that have been depleted of organic matter, or without protection or somehow burned under the sun, may have microbial effects limited or not at all. It is now possible to allow microorganisms such as mycelial roots to update appropriate soil activity. Bacteria living in the soil are important to help foods that grow plants. The chemical elements and compounds of the earth must be transformed into a form that plants can use. Decomposition process of materials to make them available to plants via bacteria, fungi and other basic organisms

Soil organic matter consists of soil microorganisms (including bacteria and fungi), decay substances (living things such as plant and animal tissues), feces and products formed by their decomposition. SOM is a heterogeneous mixture ranging from fresh plant residues to decomposition stages of highly degraded substances called humus. SOM is made from carbon-rich organic compounds. Soil organic carbon (SOC) level is directly related to soil organic matter content, SOC is usually a measure of organic matter in soil.
