Humic acid (HA) is a kind of organic matter formed and accumulated by a series of processes such as decomposition and transformation of plant remains and microbial reaction, including fulvic acid (FA). ) and Humin (HM). Composition: mainly composed of C, H, O, N, S and other elements. Composition: It contains various functional groups such as a carboxyl group, a hydroxyl group, a phenolic hydroxyl group, an alcoholic hydroxyl group, and a mercapto group.

Characteristics of humic acid

1. It is a macromolecular organic mixture, which is naturally weakly acidic. There are three components: fulvic acid, black humic acid and brown humic acid. It is usually in a black or brown colloidal state, and its color and specific gravity increase as the degree of coalification increases.

2, molecular weight from tens of thousands to millions, with a loose “sponge-like” structure, specific surface area of ​​330 ~ 340 m2 / g, with a strong adsorption capacity.

3. It is a hydrophilic reversible colloid with a specific gravity between 1.330 and 1.448.

4, carboxyl, hydroxyl, phenolic hydroxyl, alcoholic hydroxyl, sulfonic acid groups and other active groups, easy to form complexation and chelation reaction with metal ions.

The fulvic acid

fulvic acid is extracted from natural humus and is a group of substances with a small molecular weight and a yellow or brownish yellow color which is soluble in alkali, acid and water.

It is a plant growth regulator that promotes plant growth and enhances plant resistance, yield and quality.

Fulvic acid is the best core component of soil humus. It is a small molecular weight, fully water-soluble organic aromatic substance which is decomposed and decomposed by organic matter.

It is the best humic acid component in soil and the core material for the formation of soil aggregate structure.

Potassium humate is a short carbon chain molecular structure material extracted from pure natural humic acid. Potassium humate is a component of humic acid.

Humic acid is widely found in natural charcoal, lignite, weathered coal, etc. potassium humate can be prepared by extracting certain potassium humate and potassium oxide from humic acid.

Using biochemical techniques to extract fulvic acid from plants and then make potassium humate with potassium oxide.

Function to fertilizer

Chelation constants and micronutrients make it better for plant utilization; Control plant diseases and enhance mites; Promote plant microbiological activity; Slow release fertilizers, improve fertilizers and Pesticide utilization; Improve nutrient absorption, promote plant germination and growth; Accelerate sedimentation and decomposition, and improve soil structure.

Potassium humate is a pure natural mineral active potassium fertilizer. Potassium humate contains trace elements, rare earth elements, plant growth regulators, virus inhibitors and other nutrients to make nutrients more abundant and more reasonable.

Potassium humate can timely replenish nutrients lost in the soil, activate the soil, have vitality, reduce the disease caused by excessive absorption of nutrients in the soil, and replace the potassium sulfate or potassium chloride and potassium sulfate with the same content. Magnesium, but also natural and environmentally friendly.

Main effect to soil

Potassium humate can activate the squash soil, promote the physiological metabolism of various melons, fruits and vegetables and field crops, promote the development of roots and flourish stems and leaves.

Potassium humate can be applied, applied, chased, applied or chased by about 20-30 kg, which can save all kinds of fertilizers, and can make fruits and vegetables and various field crops mature for about 10 days in advance, increasing production by 20 %the above.

Improve soil aggregate structure, loosen soil, improve soil water retention and fertilizer retention capacity, adjust pH value, reduce heavy metal content in soil, and reduce salt ion damage to seeds and seedlings.
Second, nitrogen fixation, phosphorus dissolution, activation of potassium. Especially for the potash fertilizer, the synergy is particularly obvious, which plays a role in increasing roots and strengthening seedlings, resisting heavy mites, resisting diseases and improving crop quality.

Effect to plants


Strengthen the adhesion and rapid absorption capacity of plant roots, especially the physiological diseases caused by the lack of trace elements have obvious effects.

Scientifically combine new nutrition chains to fully balance plant needs. Biochemical humic acid potassium is not a pure molecular compound, but a heterogeneous composite macromolecular structure with an extremely complex mixture. Therefore, in addition to high content of fulvic acid, this product is also rich in almost all amino acids, nitrogen, phosphorus, potassium, various enzymes, sugars (oligosaccharides, fructose, etc.) proteins required for plant growth. Nutrients such as nucleic acids, humic acid and VC, VE and a large number of B vitamins are green biological fertilizers.
