Sell ahumate super refined humic acid @China (Mainland)

We are manufactory for production of leonardite humic acid,potassium humate,sodium humate fertilizers since 2000.And our commodities are of high quality.

Humic acid is one of the major components of humic substances. Chemically, it is a super-molecular aromatic acid composed by various functional groups, taking on effects of sorption, complexation, chelation, flocculation, which dissolves loads of hydrophobic matters. They can also be found in peat, coal, many upland streams and ocean water.

The benefits of Humic acid

Humic substances can be found in all soils and waters and arise from vegetable decomposition products. They are split up by extraction in hu- min, humic acid, fulvic acid and ulmic acid . Their salts are called humates, fulvates and ulmates. As main fraction humic acid forms the biological center of the humus.

The intensive monoculture and the intensified application of inorganic mineral fertilizers since beginning of the 20th century continuously decreased the rate of organic matter in soils so that agriculture reached a blind alley. Consequently of this many problems aroused, like the salinisation and calcination of soils, the decrease of the soil fertility, the destruction of useful soil micro organisms, the increase of the erosion and desertification, rising plant diseases and the accumu- lation of toxic residues in soils, e.g. herbicides. In combination with humic acid NPK fertilisers can work optimally. By addition of our products the efficiency of NPK fertilizers can be increased up to 30% respectively at the same yield the application of fertilisers can reduced, the environment preserved and costs saved.

Major applications：

Humic acid is mainly employed in industry in forms of additive, its effects are: to improve product quality, to retrench raw material and to reduce energy expenditure; for instance, it may be applied as boiler water soften agent and as petroleum drilling fluid decreasing and filtering agent. By chelating the ions, humic acids facilitate the uptake of these ions by several mechanisms, one of which is preventing their precipitation, another seems to be a direct and positive influence on their bioavailability. They also dissolve loads of hydrophobic matters and along with the above characteristic they take care of harmful matters, preventing waters from contamination. Since their pH values are below 7, namely acidic, humic acids alleviate the world-challenging issue of soil salinisation.
