Humic acid is an organic fertilizer. Natural humic acid is formed by decomposition of plant residues. Dry soil, river mud and shallowly buried weathered coal, peat and lignite are widespread. Containing carbon, hydrogen, oxygen, nitrogen and other elements, it has a certain fertilizer effect, but most of the insoluble dry water, if combined with potassium, sodium, ammonium and other substances, is easy to be absorbed by plants as nutrients.
It is powder or granular from of leonardite/lignite. Humic acid is basic raw material for manufacturers in agricultural and industrial products.
