La description
Nitrogen-containing water-soluble humic acid produced by our
company is mainly composed of a water-soluble humic acid urea
complex and a small amount of ammonium humate. No urease
inhibitors or nitrifying bacteria inhibitors were added to the
production, and no pollutants were discharged. Humic acid urea
complex was green and environmental friendly. The traditional
extraction technology of water-soluble humic acid products, such
as sodium humate, potassium humate and ammonium humate, was
replaced by NaOH, KOH, Na2CO3, NH3.H_2O or NH4HCO_3 reacting with
humic acid raw materials. The problems of high production cost,
strong alkalinity and high salinity existed in the production and
application of traditional water-soluble humic acid products in
agriculture were solved. The product is neutral, water-soluble,
slow-release and a new type of bioactive agent. It has obvious
effects in inhibiting urea decomposition, improving nitrogen
utilization rate, regulating physiological functions, promoting
the growth and development of animals and plants, improving soil
and drought resistance.
Â
Our company has mastered the production technology and technology
of sodium humate, potassium humate and potassium fulvic acid.
Sodium humate and potassium humate are mainly extracted by
alkali, even by reaction of sodium hydroxide and potassium
hydroxide solution with weathered coal, after solid-liquid
separation, concentration, drying, etc. Potassium fulvic acid is
a complex technology. It is necessary to use oxidant before
alkali extraction process to break the molecular chain of humic
acid and form fulvic acid. The effect of using lignite to extract
potassium fulvic acid is better.
Â
Sodium humate is widely used in drilling, ceramics, feed
addition, aquaculture, batteries, medicine, new materials, and
even food and beverage industries. At present, the market is very
popular.
Â
Potassium humate and potassium fulvic acid are widely used in
water-soluble fertilizers containing humic acid. The price is
much higher than sodium humate.
