  Humus
Humus formed under water is slightly different than its aerobic counterpart due more to the nature of the residues from the two different environments than the process of aerobic vs. anaerobic humification.
This is not to say that humus is immune from further decay, but its resistance to decomposition is at a level that enables it to exist for decades if not centuries as a soil conditioner, a habitat for microbial life and a vast reservoir of plant and microbial nutrient.
The formation of new humus is critical to maintaining a stable presence of this asset in the soil.

  humus - Encyclopedia.com
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 fertilizer).
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 - PermaWiki - a Wikia wiki   (Site not responding. Last check: )
Humus is a colloidal substance, and increases the soil's Cation Exchange Capacity, hence it's ability to store nutrients on clay particles, thus whilst these nutrient anions are accessible to plants they are held in the soil safe from leaching away by rain or irrigation.
Humus which is readily capable of further decomposition is referred to as effective or active humus.
Humus should not be thought of as 'dead'- rather it is the 'raw matter' of life- the transition stage between one life form and another.

 Humus Summary
Humus is often described as the 'life-force' of the soil.
Humus is a colloidal as substance, and increases the soil's cation exchange capacity, hence its ability to store nutrients on clay particles; thus while these nutrient cations are accessible to plants, they are held in the soil safe from leaching away by rain or irrigation.
Stable (or passive) humus consisting of humic acids, or humins, on the other hand, are so highly insoluble (or tightly bound to clay particles that they cannot be penetrated by microbes) that they are greatly resistant to further decomposition.

  Fertilizer - Wikipedia, the free encyclopedia
Chemist Justus von Liebig (in the 19th century) contributed greatly to understanding the role of inorganic compounds in plant nutrition and devised the concept of Liebig's barrel to illustrate the significance of inadequate concentrations of essential nutrients.
At the same time he deemphasized the role of humus.
This theory was influential in the great expansion in use of artificial fertilizers in the 20th century.

 Using humus to improve your soil organically
Humus is the loose, crumbly material that results from the decay of organic matter -- leaves, grass clippings, garden waste, peatmoss, kitchen scraps, or any such material.
Humus is important because it retains moisture in the soil, loosens the soil permitting better aeration and drainage, and encourages the increase of soil organisms which help make nutrients available to plants.
In the past, humus was assured in soil by the addition of barnyard manures.

Humus is the more or less stable fraction of organic matter remaining in a soil after the major portions of added plant and animal residues have decomposed.
Humus is characterized by dark-colored, complex, colloidal-sized, amorphous aromatic ring-type compounds, including polyphenols and polyquinones.
Humus in a soil supplies nutrients as well as growth-promoting substances (e.g., vitamins, amino acids, auxins, and gibberellins) that are necessary for plant growth.
