humification
Organic matter breakdown
Humification is the process by which organic matter decomposes into humus—the dark, stable component of soil.
Dead plant material, leaves, and other organic debris break down through microbial activity, transforming into the rich, earite substance that gives healthy topsoil its color and fertility.
Humification takes years to convert forest litter into usable soil nutrients.
