Studies on decomposition of humus in clay-humus complexes
Plant and Soil, 1984Decomposition studies with humic acids (HAs) present in HA-clay complexes revealed that such decomposition decreases at higher clay concentrations. At high clay concentration, moreover, it has also been observed that smaller and more flexible humic molecules are less susceptible to the said decomposition as compared to larger and more rigid structures.

Plant and Soil, 1984
A scheme on humus formation has been proposed. This is as follows: Lignin/carbohydrates, the chief sources of C for the microorganisms are first broken down by extracellular enzymes into smaller units. Soluble units are absorbed into the microbial cell where part of them are converted to phenols/quinones.

Effects of humus on the mobility of arsenic in tailing soil and the thiol-modification of humus
Chemosphere, 2020The ability of thiol-modified humic acids (HAs) to release arsenic in tailings soil after being modified with different sulfur-containing reagents were significantly improved. The structure and physicochemical properties of humic acid (HA) before and after thiol-modification were characterized.

Genesis of humus B horizons in hydromorphic humus podzols
Nature, 1983A distinctive podzol B horizon, characterized by accumulated humus, low-iron content, lateral uniformity in appearance and composition and frequently hard cementation, develops at the top of the water table in quartz sands on coastal plains in the subtropics and tropics.

, 2013 Humus is the black substance into which dead plants are converted by the combined action of oxygen and water. Oxygen gas penetrates humus and combines with its carbon to produce carbon dioxide gas, which is released, thereby becoming a nutrient for plants.

Starting with rock, water, and air, only the blue-green algae and the purple bacteria are able to put together a viable combination of C, H, O, and N atoms in the form of biomass. The higher plants assimilate carbon dioxide of the air but depend on microbes to supply available nitrogen.
