Humus formation from the residues of plant and animal is two-stage process: 1. The decomposition of the original components of tissues and their conversion by micro-organisms into simpler chemical compounds and partially to products of complete mineralization (CO 2 , NO 2 , NO 3 , NH 3 , CH 4 , H 2 O etc.).

Humus formation is carried out in two steps. First, the organic substances and minerals in the soil disintegrate. Next, totally new combinations of these broken-down products develop. This leads to the initial stages of humus.

Humus formation is a complex two stage process in which organic residues of plant and animal origin undergo profound transformation. 1. The decomposition of the original components of tissues and their conversion by microorganisms in to simpler chemical compounds and partially to products of complete mineralization (CO2, NO2, NO3, NH3, CH4, H2O ...

According to Aber and Melillo (1991), the decomposition process from litter to humus has two stages. In the first stage, there is rapid loss of solubles (sugars, starches, proteins) followed by cellulose, but a little loss or sometimes-even gain of lignin (insoluble decay products).

The article outlines the main stages of humus formation, including the accumulation of organic matter, mineralization, and humification, and discusses the roles of fulvic acids, humic acids, and humins in improving soil properties.

Humus refers to the product of the decomposition of animal, microbial, and plant residues in both aquatic and terrestrial ecosystems. It is a complex mixture of different compounds and is one of the most abundant forms of organic matter on the Earth's surface.

Between these two stages of the forest successional cycle, intermediary humus forms are found. They correspond to changes in soil animal communities, mostly burrowing earthworms, occurring together with changes in vegetation.

Jan 1, 2018 · Wallwork (1970) considered seven groups of animals correlated with humus systems: Acari (mites), Collembola (springtails), Myriapoda (centipedes and millipedes), Isopoda (woodlice), Annelida (referring to earthworms only), Isoptera (termites) and Insecta (insect larvae).

May 5, 2024 · The initial stage of humus formation involves the decomposition of organic matter. This process is primarily driven by microorganisms – bacteria, fungi, and actinomycetes – that break down plant and animal residues into smaller and simpler compounds.
