Humic acid is a kind of macromolecular compound with relatively complex composition. According to its solubility in different solvents, it is divided into three components, namely fulvic acid, brown humic acid and black humic acid. Humic acid is widely found in lignite, weathered coal and peat in the natural world, with a content of 30% to 70%. In the 1970s, China had set off a wave of research and application of humic substances, mainly to solve the agricultural production of fertilizer at that time. shortage.

The biological activity and special structural properties of humic acid play a peculiar role in plant growth. The organic acid substance provided by humic acid in natural coal is called MFA, and the humic acid substance produced by our first biochemical method is called BF (Biotechnolosy Fulvic scicl). This environmentally friendly green technology provides a greater platform for the application and development of humic acid products. At present, humic acid have been used in agriculture, forestry, medical and health, environmental protection, pesticides, fertilizers and other industries. In particular, people’s awareness of environmental protection, the prevalence of green health food, then solve this problem and provide these edible substances, humic acid will play an important and unique role, thus, humic acid will have a broader market space, It will also promote the faster development of this product and industry.

Principle of biological activity of humic acid

The main elemental composition of humic acid is carbon, hydrogen, oxygen, nitrogen, sulfur, and is a polycondensate of a polyvalent phenolic aromatic compound and a nitrogen compound. The molecular weight distribution is wide, the molecular weight of small molecules is tens of thousands, and the molecular weight of macromolecules is tens of thousands to millions.

The structure is also quite complicated, and contains various functional groups such as phenolic hydroxyl group, hydroxyl group, alcoholic hydroxyl group, hydrazine hydroxyl group, enol group, sulfonic acid group, amine group, free sulfhydryl group, sulfhydryl group, decyloxy group, methoxy group and the like. . Each composition is entangled by chemical and physical interactions such as bonding, hydrogen bonding, and adsorption. Due to the presence of these reactive groups, the acidity, hydrophilicity, ion exchangeability, complexation and high adsorption capacity, buffering and catalytic ability of humic acid are determined. The addition of humic acid to the feed can effectively adsorb various toxic and harmful substances produced by the feed, and can also absorb toxic substances produced by digestion and metabolism during digestion and metabolism. Such as: amines, hydrogen sulfide and other substances, maintaining the normal microflora of the intestines.

Humic acid is added to the feed and can also act as a drug, which has a significant therapeutic effect on intestinal ulcers and gastritis. Because humic acid contains small molecules of fulvic acid, it can adhere to the surface of the ulcer, which can quickly stop bleeding and facilitate rapid healing of the tissue. Humic acid has an immune-enhancing effect on animals, and promotes antigenic substance uptake, cellular immunity and humoral immunity in the immune process. Humic acid contains sulfhydryl groups to participate in the body’s redox reaction, maintain strong metabolism, and promote cell proliferation.

Humic acid can also act on the autonomic nervous system, inhibiting the excitation of the sympathetic nerves, making the animals quiet and reducing consumption. Because humic acid is an organic acid, it can regulate the pH value of digestive tract, promote the secretion of digestive enzymes in young animals, activate the activity of various enzymes in the body, change the permeability of cell membrane, improve the absorption of feed nutrients, and improve the feed. Utilization, promote growth and development. For biochemical fulvic acid, it not only contains humic acid, but also contains a certain amount of nucleic acid, amino acid, VB, VC, inositol, polysaccharide, in addition to having strong biological activity, it is also an important nutrient for animals.

In summary, according to clinical evidence, humic acid has hemostasis, anti-inflammatory, analgesic, astringent, adsorption, anti-allergic, secretory secretion, regulation of gastrointestinal function, improve immunity and enhance animal disease resistance. At present, some feed manufacturers, in order to cater to the consumer psychology of the farmers, improve the growth of animals, the pursuit of feed effects, the addition of a large number of antibiotics in the feed, due to the residues of antibiotics, directly affect people’s health. As a green product, humic acid can be added to the feed to replace antibiotics. Scientific research in recent years has shown that humic acid, as a new type of feed additive, has a peculiar effect and plays a very important role in aquaculture, and will certainly promote the development of the feed industry.

Prospects for the development of humic acid

Humic acid is used in aquaculture. It is still rare in domestic reports. As a natural active substance, it can be used as a disease prevention agent within a certain range. The development of humic acid has broad market prospects. Problems in the humic acid industry: If the scale of production is small, the technology is relatively backward, the quality is unstable, the technical strength of each enterprise is weak, and the development and application research are not enough, thus restricting the development of this industry. The peculiar effect of humic acid is not well understood, and further research is needed, as well as increasing the application space and application value of humic acid.

Sodium humate has been used as a feed additive in poultry farming and as a synergist in aquaculture, and has achieved significant economic benefits.

Fulvic acid is the smallest and most active component of humic acid. It is the essence of the active ingredients of humic acid. In the practical application of agricultural production, the stability of fulvic acid is the best.

Fulvic acid is the best core component of soil humus. Is that the molecular weight generated by decomposition and decomposition of organic matter is small, Fully water soluble organic aromatics,
Is the best humic acid in the soil,It is the core material that forms the structure of soil aggregates.

Advantages of fulvic acid


The fulvic acid contains functional groups such as carboxyl group and phenolic hydroxyl group, which has strong complexation, chelation and surface adsorption ability, can reduce the loss of ammonium nitrogen, increase the moving distance of phosphorus in the soil, and inhibit the fixation of water-soluble phosphorus in the soil. Ineffective phosphorus is converted into effective phosphorus, which promotes the absorption of phosphorus by roots; fulvic acid can absorb and store potassium ions, and the effective potassium content is especially effective for potassium fertilizer.

The fulvic acid can increase the utilization rate of nitrogen, phosphorus and potassium nutrients in the fertilizer by more than 20%.

The synergistic effect of fulvic acid on nitrogen fertilizer The active groups of fulvic acid (including carboxyl groups, hydroxyl groups and certain groups containing P, O, N, S) are generally electron donors, which are easily associated with many electron acceptors. (Multivalent metal ions, organic groups or ions) constitute a coordination compound called a complex or a chelate. For example, fulvic acid-urea, etc., is actually a complex (chelating) substance, which can reduce the loss of ammonium nitrogen and increase the utilization rate of nitrogen fertilizer. Oxidatively degraded nitroxanthohumic acid can inhibit urease activity and reduce urea volatilization.

Adding fulvic acid to ammonium bicarbonate can reduce the nitrogen volatilization rate of ammonium bicarbonate from 13.1% to 2.04% in 6 days. In the farmland test, the effect of ammonium bicarbonate was maintained for more than 20 days, and the ammonium fulvic acid could reach more than 60 days. The addition of fulvic acid, especially nitroxanthate, to urea can form a urea complex, which slows the decomposition of urea, prolongs the fertilizer efficiency, reduces the loss, and increases the utilization rate of urea by 30% and the aftereffect by more than 15%. As a result of measuring the nitrogen use efficiency, the utilization rate of fulvic acid was increased from 30.1% to 34.1%, and the nitrogen uptake was increased by 10%.

The effect of fulvic acid combined with nitrogen on plant growth and development is very obvious. When nitrogen and fulvic acid are sufficient, plants can synthesize more protein, promote cell division and growth, so the plant leaf area grows faster, and more leaf area can be used for photosynthesis. It has obvious effects on promoting plant growth and health. Often, after application, the leaf color turns green quickly and the amount of growth increases.

The synergistic effect of fulvic acid on phosphate fertilizer: Degraded fulvic acid can increase the distance of phosphorus movement in the soil, inhibit the fixation of water-soluble phosphorus in the soil, convert the ineffective phosphorus into effective phosphorus, and promote the absorption of phosphorus by roots. Use fulvic acid to protect water-soluble phosphate fertilizer or phosphorus-based compound fertilizer to reduce phosphorus fixation; promote phosphorus absorption and increase phosphorus fertilizer utilization rate.

The fertilizer efficiency test showed that adding 10-20% of fulvic acid to calcium, heavy calcium or ammonium phosphate could increase the fertilizer efficiency by 10-20% and the phosphorus uptake by 28~39%. The radioactive phosphorus tracer test measures the utilization rate of phosphate fertilizer. After adding fulvic acid, the utilization rate of phosphate fertilizer increased from 15.4% to 19.3%, that is, the utilization rate of phosphate fertilizer increased by a quarter.
The fulvic acid and phosphate fertilizer participate in photosynthesis, respiration, energy storage and transmission, cell division, cell enlargement and other processes in plants.

Synergistic effect on potassium fertilizer: The acidic functional group of fulvic acid can absorb and store potassium ions, and reduce the amount of potassium lost with water in sandy soil and leached soil. The fulvic acid prevents the fixation of potassium in sticky soils and increases the amount of exchangeable potassium.

fulvic acid has a dissolution effect on the potassium-containing minerals, slowly increasing the release of potassium and increasing the content of available potassium in the soil. Fulvic acid can also use its biological activity to stimulate and regulate the physiological metabolism of crops, increasing the potassium uptake by more than 30%.

The combination of fulvic acid and potassium promotes photosynthesis, can significantly increase the absorption and utilization of nitrogen by plants, and is quickly converted into protein, and can also promote plant economic water.

Promote the absorption of micro-fertilizer and effectively solve the deficiency syndrome: the trace elements in the chelating agent of fulvic acid form a humic acid chelate compound which is highly mobile and easily absorbed by crops, and is transmitted to the defective part of the crop to effectively solve the deficiency syndrome.

In addition to a large number of elements such as nitrogen, phosphorus and potassium, crop growth and development also requires trace elements such as iron, boron, manganese, zinc, molybdenum and copper. They are components of various enzymes in the crops and promote the normal growth and development of crops. Increasing disease resistance, increasing yield and improving quality all have important implications. Most of the trace elements in the soil are in an ineffective state that plants are difficult to absorb, and the application of trace element fertilizers to the soil is also easily fixed by the soil.

According to the research, decoctantic acid can react with trace elements such as iron and zinc to form a sulphate trace element chelate compound with good solubility and easy to be absorbed by plants, such as fulvic acid-Zn and fulvic acid-Mn. , fulvic acid-Fe, etc., is conducive to the absorption of roots or leaves, and can promote the trace elements from the roots to the upper part of the ground.

The experiment showed that the amount of iron fulvic acid entering the roots from the roots was 32% more than that of ferrous sulfate, and the number of movements in the leaves was twice that of ferrous sulfate, which increased the chlorophyll content by 15 to 45%, effectively solving the problem caused by iron deficiency. Yellowing of the leaves.

Fulvic acid, important for agriculture

As a plant growth regulator, fulvic acid is the best component of soil humus, not only reducing crop burden, increasing soil fertility, enriching the matrix of soil bacteria, but also improving crop yield and quality to help agriculture Achieve long-term development goals of increasing production, upgrading, and raising land. Thereby solving the quality problem of crops. ”

Ore source humic acid belongs to a natural biological source.

In particular, humic acid is the organic substance formed by the remains of plants and animals through the decomposition and transformation of microorganisms and some changes in the earth’s crust, so it must be a natural substance.

Some farmers have asked us before: “The humic acid water-soluble fertilizer that has been used for so many years, every time you buy it, you can smell the sweetness, that is, the sugary taste, but the humic acid water soluble fertilizer you bought today has no taste at all. Will it be fake?” You can think about it.
At present, the source humic acid is an organic substance formed during the crustal change. The main elements are actually carbon, oxygen, hydrogen, nitrogen and sulfur. The content of carbon is the highest, which is what we are talking about today. Active ore source humic acid.

The ore source humic acid is formed in four stages: peat stage, lignite stage, bituminous stage, anthracite stage. In this process, the raw material purification of humic acid mainly passes through three stages of peat stage, lignite stage and weathered coal stage. The humic acid content is the highest in the three stages.

The humic acid with peat as raw material is called original humic acid, and the humic acid with lignite and weathered coal as raw material is called ore source humic acid.

If the source humic acid is classified by molecular weight, The molecular weight of black humic acid is above 5000 Daltons, the molecular weight of brown humic acid is 1000-5000 Daltons, and the molecular weight of fulvic acid is below 1000 Daltons, according to the mass unit of Dalton. The lower the mass unit, the higher its activity.
