Humic 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. This organic matter does not compost but humifies. Over years of process, it forms the substance humus. Humus is formed by the breakdown of plant or animal carbon. This humification process mainly takes place by bacteria. If humus can build up for a long time in the soil, it is eventually converted into fulvic acid. This substance is much lighter than humus and has a different structure.

What is the function of humus?

Humus forms the start of many soil processes. Humus provides food for a large number of bacterial species and other soil life. Without humus, there can be no normal development of soil biology. In addition, humus retains water, nitrogen, and other minerals in the soil, preventing them from leaching.
