Humus acids are the humified organic substances that provide nutrition to the soil and soil life. In nature, organic matter falls to the ground and underground roots die off. This organic matter does not compost but humifies. From this, over many years, the substance humus forms. Humus is created by the breakdown of plant or animal carbon. This humification process mainly occurs through bacteria. If humus can be built up over a long period in the soil, it is eventually converted into fulvic. This substance is much lighter than humus and has a different structure.

What is the function of humus?

Humus forms the beginning of many soil processes. Humus provides food for a large number of bacteria species and other soil life. Without humus, there can be no normal development of soil biology. Additionally, humus retains water, nitrogen, and other minerals in the soil, preventing leaching.
