Leaching: Part of water-soluble substances present in the fragmented and decomposition detritus (e.g., sugars, inorganic nutrients) go down into the soil horizon by percolating water and get precipitated as unavailable salts.

Mineralisation: It is the release of inorganic substances by saprophytic microbes (e.g. CO₂, H₂O, minerals) from organic matter or humus during the process of decomposition.
