With the needs of the global fertilizer industry, especially the upgrading of the fertilizer industry, humic acid is an important organic raw material and green environmental fertilizer, and its development has attracted more and more attention from the industry.

Increase soil nutrition

Humic acid can protect and store nutrients by adsorbing, complexing, chelation, ion exchange, etc. in the soil, or indirectly through activation or inducing soil enzymes. It plays an important role in forming a slow-acting nitrogen source, fixing nitrogen in the atmosphere, promoting the dissolution of insoluble phosphorus and potassium, reducing the loss of various nutrients, and promoting inorganic components in various rocks or minerals. Gradually dissolve.

Improve the physical structure of the soil

The gelling properties of humic acid promote the bonding of soil particles to form a stable agglomerate, which promotes the formation of soil aggregate structure. Humic acid can deepen the color of the soil, which is good for absorbing solar radiation and increasing ground temperature.

Increase soil moisture content

Humic acid can increase soil water holding capacity by 5 to 10 times.
Improve the soil. Humic acid has the ability to regulate and buffer soil pH, and can also improve soil cation exchange capacity and reduce soil salt content.

Promote soil microbial activity

Humic acid provides a major source of energy for soil microbial activities, improving the microbial population in the soil, and is suitable for the growth and reproduction of beneficial bacteria.

Reduce soil pollution

Humic acid has a buffering and attenuating effect on soil pollutants. It inhibits the activity of nitrifying bacteria and denitrifying bacteria in the soil and reduces the conversion of ammonium nitrogen to nitrate nitrogen. It forms a difficult macromolecular chelate with a small amount of heavy metals in the soil, reducing heavy metal pollution.

potassium humate physiological effects as following:

Strengthen breathing

Some people call potassium humate as a “breathing fertilizer.” It is generally considered that, because of its structure containing phenol and hydrazine in its molecule, it can be a carrier of hydrogen and an activator of oxygen. Form a redox system that can deliver electrons and promote respiration.

Promote the absorption and transportation of mineral elements

Potassium humate can form complexes or chelates with polyvalent metal ions through the oxygen-containing functional groups on its molecular side chains, which can activate various metal elements in the soil, especially trace elements, and make them Never used state to become available. Therefore, it is easily absorbed and transported by plants.

Can increase the chlorophyll content in leaves

This is a very intuitive effect. Any crop that uses potassium humate can clearly see that the crop is greener. Due to the increase in chlorophyll, it naturally increases the photosynthesis of plants and can synthesize more carbohydrates.

Regulate water metabolism

The most obvious is that the pores on the leaves become smaller after application of potassium humate , which reduces water transpiration and has drought resistance.

Can promote the metabolism of sugars, nucleic acids and proteins

Application of potassium humate can improve crop quality. There are many reports such as tobacco leaves, vegetables and fruits.

It has the function of growth regulation or similar plant hormones, and the most obvious is to promote rooting, green preservation, anti-aging and so on.

These physiological effects of potassium humate indicate that, as a class of substances, it can effectively regulate the physiological metabolism and growth of plants, and provide a biological basis for promoting high yield of crops.

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.

1. Sodium humate used in livestocks and sodium humate formula.

Recessive mastitis is a common and frequently-occurring disease in dairy cows. According to the statistics of the International Dairy Federation, the incidence of this disease is as high as 50%.

Among the cows that have been eliminated due to various diseases, recessive mastitis takes the first place. In the United States, milk production due to the disease has declined, and annual economic losses amounted to $1 to $1.2 billion. In China, Inner Mongolia, the four cities of the two cities, the average recessive mastitis cattle accounted for about 80%, which is the main factor restricting the health and milk production of dairy cows for several years.

Some units in Inner Mongolia treated cryptic mastitis with sodium humate (25g/d•head). The cure rate from day 8 to day 58 was 15.71~52.38%, and the effective rate was 55.71~84.76. %. The addition of sodium humate was stopped for 30 days and 60 days, and the consolidation rates were 93.60% and 73.25%, respectively.

The experiment also found that the lymphocyte conversion rate in bovine blood fed with sodium humate increased from 47.5% to 57.1%, and whey globulin also increased, indicating an increase in immune function.

2.Goat abortion rate decreased from 19.4~28.05% to 1.62~7.69%, and the postpartum incidence

It is believed that the primary causes of the incidence in China’s Mongolian region are malnutrition caused by severe natural conditions such as wind and cold, grassland degradation, lack of drinking water and parasite invasion, low disease resistance, and infection by certain pathogens.

A livestock station in Etuoke Banner, Inner Mongolia [36] treated the “preservation powder” prepared with sodium humate as the main raw material for the treatment of goat abortion for three years, the abortion rate decreased from 19.4~28.05% to 1.62~7.69%, and the postpartum incidence ,The rate is also significantly reduced.

3.Sodium humate used to treat diseases in lambs

Some places in Inner Mongolia insisted on the treatment of lambs with sodium humate for 3 years, and the cure rate reached 83.3~98.1%. Some animal husbandry stations in Xinjiang used humate to treat lamb diarrhea, in which 100% of simple dyspepsia recovered, 92.8% of toxic indigestion recovered, and 75% of dysentery recovered.

Especially effective to Lamb stomatitis.

The incidence rate in Xinjiang is almost 100%, seriously affecting the diseased lamb breastfeeding, resulting in malnutrition of the lamb, and often died of secondary infection. Wash with 0.5gHA powder or 4% sodium humate solution, the cure rate is above 97.7% .

The incidence of sheep disease in winter is high, often causing a large number of sheep to lose weight, hair loss and even death. Generally use 666+ grams of Liaolin or Lin Dan medicine bath, but the residual toxicity and side effects are large. The humic acid sodium chlorpyrifos (sodium humate + lindane and other complex preparations) developed in Xinjiang is superior to lindane emulsifiable concentrate and deltamethrin, and can prevent meat contamination and improve the quality of sheep skin.

Sodium humate increases yield, reduces disease and pollution

Many fish farms have reported that the feed intake of fish after feeding with sodium humate increased, and the disease resistance and survival rate of larvae increased significantly. According to reports, the fish farms in Baigezhuang District, Hebei Province, soaked the feed cornmeal with 4% sodium humate to make feed and feed the fish.

After 40 days, the survival rate of white carp and grass carp was 298.4% and 24.5% higher than the control, respectively. The weight gain was 190.8% and 34.5% more than the control. Yu Linchuan and other modified humic acid preparation FA-1 for feeding river crab for 6 months, the yield per mu increased by 20kg, the ratio of production/injection was 55:1;

The survival rate of the young crab was soaked with FA-2 solution, and the survival rate was increased by 10%; -1, the average weight gain increased by 5.7%, and the survival rate increased by 12.14%. Sodium humate also has certain effects on the prevention and treatment of certain common diseases. For example, the Animal Husbandry and Fisheries Bureau of Beijing Haidian District uses a 0.02% concentration of sodium humate to “bath” the fish infected with white skin disease and water mold, and healed after 7-10 days. The survival rate was 100%, while the control group mortality was 7.5% [41].

It also has a certain effect on fish enteritis.

The cationic semipermeable membrane test [42] showed that the absorption of Cu in the complex state by the surimi was about half lower than that of the free Cu2+. Obviously, the sodium humate treated water may reduce or prevent the pollution of heavy metals to fish, Fish food safety offers new ideas.

The amount of humus can adjust the depth of the soil color, the black soil, the humus content is higher; when the humus content is small, the soil is gray or grayish white, such as Xinjiang gray desert soil.
Minerals give the soil a color other than black. For example, red soil is due to high levels of iron oxide in the soil.

The iron oxide reacts into hydrated iron oxide and the soil becomes yellow. When the ventilation is poor and the oxygen is deficient, the iron oxide turns into ferrous oxide, and the soil appears grayish blue. White is related to the salt in the soil. Purple soil is formed by the development of purple sandstone and shale weathering, and is distributed more in Sichuan.

Humic acid is the child of the earth. It is an important factor in the transformation of the earth’s matter and energy, accumulating physical, chemical and biological energy.
Humic acid is a macromolecular organic polymer with a variety of chemical structures and a variety of reactive functional groups with physical, chemical and biological activities.
Humic acid occupies an important position in the earth’s bio-carbon cycle. Humic acid carbon accounts for 67.6% of the biosphere organic carbon and accounts for more than 60% of the soil organic matter.
Humic acid is the foundation and material guarantee for healthy soils.
Whether it is coal source humic acid (mud carbon, lignite, weathered coal), plant source (various plant tissues), animal sources (livestock and poultry manure, animal by-products, etc.), the roots are derived from the soil.
The low carbonization properties of humic acid are not only conducive to energy conservation, low carbon, and green, but also more practical for global carbon cycle and climate change.

Humic acid is derived from the soil and is fed back to the soil, pure and more efficient. Above, the physical, chemical, biological and ecological effects of humic acid on the soil have become a major factor in promoting humic acid fertilizers throughout the country.
