What happens during leaching in decomposition?

Leaching is the physical removal of water-soluble substances from fresh litter or soil organic matter. Rain or flowing water dissolves sugars, amino acids, tannins, mineral ions, and dissolved organic carbon and transports them into deeper soil horizons or aquatic systems. It can cause rapid initial mass loss without requiring enzymatic digestion. Leaching may also alter subsequent microbial activity by removing labile substrates or inhibitory compounds, so its effect on later decomposition depends on which solutes are exported. Mass loss alone cannot identify mechanism, because leaching, frag
