Bacterial and fungal enzymes degrade detritus into simpler inorganic substances in a process is called catabolism.

Humus is less resistant to microbial action and undergoes decomposition at an extremely slow rate.

By the process of leaching, watersoluble inorganic nutrients go down into the soil horizon and get precipitated as unavailable salts.

Decomposition is largely an oxygen-requiring process.
