	Humus is non-living [[Organic Matter\|organic matter]] within soil, derived from the microbial [[decomposition]] of plants and [[animals]]. [6] The substance left behind, known as humus, consists of approximately 60% carbon, 6% nitrogen, as well as small amounts of sulfur and phosphorus. Humus is generally dark colored, though there is observable variation in shade, highly influenced by climate. There is lighter humus coloration present across the tropics and subtropics, whereas humid-temperate zones produce darker and more intensely colored humus. In agricultural terms, humus can be described as well aged [[compost]]. [[Organic Matter\|Organic matter]] decomposes molecules into smaller molecules by [[microorganisms]] in the soil. Most of the chemicals in this organic matter can be extracted by microorganisms and can be shared with other beings within the soil. Humus has a wide variety of decay (ex. peatmoss, gradd, leaf compost, wood chips, decayed sawdust, garden waste, etc). [3] Humus has higher water adsorptive capacity than [[clay]].

	[[File:humification.png\|thumb\|right]] Humification is the process of formation of humic substances decomposed from plant remains. This is results from oxidation by addition of oxygen from oxygenated water and lowering the groundwater table, heat and exposure, and pH values of water in the peat. Fungi and microbes attack lignin that brings cells, fibers, and vessels of wood and converts them into humic substances. Kodel-Knabner has summarized the formation of humus as selective preservation of plant and microbial polymers, direct transformation and microbial resynthesis. Darker colors signify strong humification and lighter colors point to wetter periods and less humification. Humification accelerates at high temperatures.
