Decomposition

The effect is to make the decomposition Organic compound Gradually the degradation process of matter, it is composed of a variety of biological.
Decomposition
The decomposition process is relatively complex, can be divided into three stages:
1, mechanical action phase: due to the physical and biological effects, animal and plant body was decomposed into particles and debris, namely fragmentation.
2, biological Alienation effect Stage: Sapropytes Under the action of the enzyme, the transformation of organic debris into humic acid and other soluble organic compounds, namely from polymer monomers and then into. humic acid And other soluble organic inorganic slow decomposition, becoming a producer can be reused by.
3, the leaching process: soluble substances leached out by water, into the soil. stay nature In these three processes are cross, mutual influence.
For example: in the process of decomposition of leaves, leaf still when plants, microorganisms have begun decomposition, once fell to the ground for dead twigs and withered leaves, bacteria, fungi and actinomycetes actinomycetes and microbial decomposition, but also by some invertebrates such as centipede. Bomb tail. Earthworm Such as feeding, a large number of organic debris is not digested by digestive tract From the organic matter exposed leaf area increased more than and 10 times, more vulnerable to microbial decomposition. In this sense, most of the decomposition of both consumers and decomposers.
The organic residues in soil, decomposed began decomposition, decomposition of complex physical and biological generally increased over time, their biological diversity decomposition also increased, with the progress of the decomposition process, decomposition rate decreased gradually, the diversity of organic matter to decomposition is also reduced, until the end to be reduced inorganic materials.
All kinds of organic matter decomposition speed is different, generally there are 50% glucose down quickly, 3 days in the decomposition of cellulose decomposition; slowly, 24 days in only 65% of the humus decomposition; the slowest in podzol can be stored in 250 years.
