Humic acid

Humic acids are plant and animal remains, mainly plant remains, a class of
organic substances that are produced and accumulated through microbial
decomposition and transformation, as well as through a series of processes in
geochemistry. The basic structure of humic acid macromolecule is Simple
aromatic rings and Aliphatic Ring, which is connected with carboxyl, hydroxyl,
carbonyl, Quinonyl, methoxy and other functional groups.
Applications:In agriculture, humic acid fertilizer (for example, ammonium
humate fertilizer can be made by neutralizing humic acid with ammonia) combined
with nitrogen, phosphorus, potassium and other elements, the invention has the
functions of increasing fertilizer efficiency, improving soil, stimulating crop
growth, improving agricultural product quality, etc. Magnesium humate, zinc
humate and urea iron of humate have good effects on supplementing magnesium
deficiency in soil, zinc deficiency in maize and iron deficiency in fruit trees
respectively Treatment of Apple Tree canker with sodium humate.
In animal husbandry, sodium humate is used in deer Antler hemostasis, nitro-
humate urea complex as cattle feed additive also has good effect.
In industry, humic acid sodium is used to adjust ceramic sludge, low pressure
boiler and locomotive boiler to prevent scale, humic acid ion exchanger is used
to treat wastewater containing heavy metals, and sulphonated humic acid sodium
is used as cement water reducing agent Humic acid products are also used as mud
treatment agents for oil drilling (See Oilfield Chemicals) ; purified humic
acid is used as cathode expansion agent for lead-acid batteries.
