humus (hyo͞o`məs), organic matter that has decayed to a relatively stable, amorphous state. It is an important biological constituent of fertile soilsoil,
surface layer of the earth, composed of fine rock material disintegrated by geological processes; and humus, the organic remains of decomposed vegetation. In agriculture, soil is the medium that supports crop plants, both physically and biologically.

Humus is formed by the decomposing action of soil microorganisms (e.g., bacteria and fungi), which break down animal and vegetable material into elements that can be used by growing plants. Technically, humus, as the end result of this process, is less valuable for plant growth than are the products formed during active decomposition (see fertilizerfertilizer,
organic or inorganic material containing one or more of the nutrients—mainly nitrogen, phosphorus, and potassium, and other essential elements required for plant growth.

Because of its low specific weight and high surface area, humus has a profound effect upon the physical properties of mineral soils with regard to improved soil structure, water intake and reservoir capacity, ability to resist erosion, and the ability to hold chemical elements in a form readily accessible to plants.Humus an organic, normally dark-colored part of the soil formed as a result of biochemical transformation of plant and animal residues. Humus consists of humic acids (most important for soil fertility) and fulvic acids (crenic acids). Humus contains the main elements of plant nutrition that become available to plants as a result of microbial activity. humus[′hyü·məs] (geology) The amorphous, ordinarily dark-colored, colloidal matter in soil; a complex of the fractions of organic matter of plant, animal, and microbial origin that are most resistant to decomposition. humusA brown or black material formed by the partial decomposition of vegetable or animal matter; the organic portion of soil.humus a dark brown or black colloidal mass of partially decomposed organic matter in the soil. It improves the fertility and water retention of the soil and is therefore important for plant growth humusenUK
humus the organic material that is derived from the breakdown of plant and animal material occurring in the surface layers of the soil. Humus is black and colloidal in nature, coating the soil particles and improving the fertility of soil in several ways: - in acting as a reservoir of numerous nutrients which it prevents from leaching deeper into the soil layers;
- in increasing the water holding capacity of the soil and
- in improving the soil texture (friability).
