Decomposition process

Process of Decomposition

A complete process of decomposition takes place in five different steps:

Fragmentation – It is the initial stage of decomposition. Fragmentation means the breakdown of detritus into smaller pieces by the detritivores.

Leaching – The fragmented particles may contain a lot of water-soluble nutrients which are inorganic in nature. These nutrients get dissolved in the water and seep into the soil and get precipitated in the process of leaching.

Catabolism -Once the complex material is broken down into smaller particles and the inorganic <a href="https://byjus.com/biology/nutrients/">nutrients</a> are removed, it is time to convert the detritus into simpler inorganic compounds. This process is carried out by various fungal and bacterial enzymes by the process of catabolism.

Humification – It is the process of formation of a dark colored layer of amorphous substance on the soil called humus. It cannot be decomposed easily as it is highly resistant to action by microbes. The layer of humus is very rich in nutrients as it provides high fertility to the soil.

Mineralisation – It is the final step in the process. Mineralisation is the process of the degradation of the hummus to release inorganic nutrients.
