Humic acid fertilizer is what? Humic acid fertilizer is the main component of humic acid. In fertile soil, especially in the maturity of the heap (沤) fertilizer, manure contains many humus, and the main component of humic acid is humic acid. Humus is a dynamic, plant residues, under the action of microorganisms, after complex biochemical changes, condensation into complex organic polymer compounds. It consists of carbon, hydrogen, oxygen, nitrogen and a small amount of phosphorus, sulfur and other elements in the soil more stable. Humic acid is black or brown amorphous colloid, with acidic, negative, strong
