Decomposition is a process in which the physical and chemical breakdown of complex organic matter will take place with the help of decomposers. The basic steps involve:
Fragmentation of detritus – Leaching – Catabolism – Humification – Mineralisation. Mineralisation: It is the release of inorganic substances by saprophytic microbes (for example CO2, H2O, minerals) from organic matter or humus during the process of decomposition. They are formed along with simple and soluble organic substances when digestive enzymes are poured over organic matter by saprotrophic microbes.
