Material that can be broken down by bacteria (fats, meats, plant life).
Once-living material (typically with high carbon content), mostly of plant origin.
undecayed plant and animal material present in soil.
Previously living material (e.g., leaves, branches, or animals) that have decomposed.
Anything that is living or was living; in soil it is usually made up of nuts, leaves, twigs, bark, etc.
material originating from any living organism (i.e., the remains of plants, animals, fungi, or other organisms).
Organic material (or matter) is derived from living or once-living organisms. It includes leaves, manures, fungi, and bacteria --to name only a few examples. Organic material is an important component of good soil-structure. It feeds microorganisms and supplies nutrients to plants.
The accumulated remains of plants, mostly. Plant remains accumulate where production exceeds decomposition; this typically occurs, on the Kenai Peninsula, not because production is so high, but because decomposition is low. Decomposition is low because of several factors, but primarily because oxygen is in short supply because soils are saturated. Therefore, accumulated organic material indicates a wetland.
substances that contain carbon, as well as other chemical elements. Plants are a primary form of organic material. Secondary forms include human and animal excrement.
plant or animal residues or derivatives.
Any material which originated as a living organism. (i.e. peat moss, compost, manure)
any basic living material, anything from bacteria to fungus and up
