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.

Potassium humate effect on soil improvement of structure

Potassium humate is a humus substance, which can affect the nature of the soil, and promote the formation of a more stable agglomerate structure in the soil, so that the aggregate content of ≥0.25mm in the soil increases by 10-20%, and the organic matter content increases by 10%. Keeping the soil moist and increasing ventilation is conducive to the growth of crops.

Enhance soil water retention

Potassium humate is a hydrophilic colloid with strong water absorption capacity. The maximum water absorption can exceed 500%. The weight of water absorbed from saturated atmosphere can reach more than double its weight. The mineral colloid is much larger; potassium humate inhibits crop transpiration, so that the soil water consumption rate is slowed down and the soil water content is correspondingly increased.

Potassium humate effect on soil improvement to Enhance soil fertility

Potassium humate itself is an organic acid that increases the dissolution of mineral parts of the soil, provides soil nutrients, and increases nutrient availability through complexation. As a kind of organic colloid, the source of Potassium humate has positive and negative charges, which can adsorb cations and cations, so that these nutrients can be stored in the soil, which will not be lost with water, and improve the utilization rate of fertilizer, which is especially important in sandy land.

Adjusting the pH of the soil solution

Potassium humate and humic acid transform each other to form a buffer system, which acts to regulate the pH of the soil solution.

Reduce soil salinity

Complexation of potassium humate, sequestration of metal cations in the soil, and its porosity (larger specific surface) can adsorb ions or molecules in the soil solution, reducing the concentration of salt in the soil solution.

Biological effects

Potassium humate contains a variety of oxygen-containing functional groups, which determine its physiological activity, thereby regulating the life activities, promoting the growth and reproduction of beneficial bacteria, and inhibiting the number of harmful microorganisms; the carboxyl groups and phenolic hydroxyl groups in potassium humate have Must inhibit the role of the virus.

In all the living things in this carbon planet, carbon is the basic element, and the organic matter formed by carbon as the framework is the basic material of life.

At present, China’s cultivated land faces severe challenges, with poor depletion (slab formation, desertification, salinization), and low- and medium-yield fields accounting for 74%, resulting in widespread weak roots, sub-health, and frequent diseases.

Due to the indifference to carbon and the fact that farmers do not care about arable land, do not cultivate fertility, and rely on chemical fertilizers and pesticides, the “chemical farming” model has been popularized in China’s hundreds of millions of acres of cultivated land. We have carried out carbon plundering of cultivated soil for 30 years. .

Plant carbon nutrients come not only from the “channel” of carbon dioxide photosynthetic transformation by chlorophyll, but also from another pathway that roots absorb from the soil. Leaf absorption and transformation is the main force of carbon accumulation, and soil carbon nutrient can produce serial promotion and energy transfer to soil fertility (ie, physical fertility, chemical fertility, and biological fertility), which promotes secondary processing of soil to fertilizer, thus directly affecting Photosynthetic conversion efficiency of the leaf suction channel.

Soil organic matter is a natural “carbon pool”, but the carbon in organic matter cannot be directly absorbed by plants. Only by biochemical action, the small molecule water-soluble organic carbon is gradually decomposed, which is the true plant carbon nutrient. The carbon nutrient content of the fertilizer determines the organic fertilizer efficiency of the fertilizer. Carbon nutrients are the basic substances for the three fertility of NPK. Soil-poor organic carbon microbes lose energy and cannot reproduce, which is the root cause of soil compaction and the main reason for low fertilizer utilization. Agriculture needs to reach a new level, food must be safe, and the biggest room for improvement is carbon supplementation.

Humic acid is an “ecological factor” in nature. It is the “grand baby” of the soil, the “white blood cell” of the water body, the “safeguard” for purifying the environment, and the “buffer” of the carbon cycle. Over the past 18 years, the Association has been committed to the development of green and low-carbon, and has always made a positive contribution to climate change mitigation.

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 hum i c 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.

The way people grow and manage is constantly changing with the advancement of science and technology. However, the status of soil as a carrier for growing crops has not been shaken. Everything needs to grow well, and the fertility of the soil is One of the main determinants, the organic matter content in the soil determines the fertility of the soil.

Organic matter humic acid, organic matter is not equal to hum i c acid

1.Polymer chemists believe that the lignin content determines the amount of humic acid formed.

2.soil scientists believe that: soil organic matter through the natural mineralization / humification to form humic – humic acid, ranging from two or three years, more than one hundred years. At present, the average content of soil organic matter in China is around 2.5%. According to the proportion of soil humic acid 60%, the humic acid content is less than 1.5%.

3.Coal chemical scientists believe that peat, weathered coal and lignite are rich in humic acid. Among them, peat formation takes thousands of years, humic acid content is generally greater than 20%; weathered coal, lignite formation requires tens of millions to hundreds of millions of years, humic acid content is high, about 40% to 70%. More than 30 years of scientific research have shown that coal humic acid and soil humic acid have similar physical properties, chemical composition, molecular structure and molecular weight range, with consistent application characteristics.

4. people usually refer to the organic matter – mainly crop straw, livestock and poultry manure, industrial by-products (distiller’s grains, sugar factory waste, animal skin, etc.), urban kitchen waste, etc. as raw materials, most of the lignin content is very low, very It is difficult to form industrial grade humic acid.

In summary, organic matter humic acid, humic acid must be the best organic matter.

Humic acid is the most vital element of organic matter in the soil,role of humic acid as following:

1.Humic acid is a soil improver

With the provision of people’s living standards and lifestyle changes, as well as the development of inorganic fertilizer industry with convenient application and significant increase in production, the “dirty, rotten and stinky” farmyard manure has been increasingly ignored by modern farmers.

Therefore, from the current fertilization structure, heavy inorganic and light organic fertilization habits are very common, especially in the production of food crops. In the long run, it is bound to destroy the soil structure, leading to soil compaction and soil fertility decline. Based on this situation, it is particularly important to develop a convenient and hygienic organic fertilizer source.

Humic acid can promote the formation of soil aggregate structure, reduce soil bulk density, increase cation substitution, and adjust soil pH, thereby contributing to soil water retention, fertilizer retention, heat preservation and ventilation.

In addition, since humic acid is a high molecular organic substance, it can provide sufficient carbon source and energy for soil microorganisms after being applied to the soil, promote microbial metabolism and reproduction, thereby increasing the amount of soil microorganisms, enhancing soil microbial activity, and improving soil microenvironment. This is especially important for improving and fertilizing soil.

2.humic acid is a synergist of fertilizer

The application of NPK fertilizer has played a decisive role in improving the output of agricultural products, but the phenomenon of high yield and inefficiency has become a major problem in the high yield and super high yield cultivation of crops in China. How to strengthen the comprehensive management of nutrient resources and improve the utilization rate of fertilizers is becoming the focus of research in modern agricultural management systems.

To this end, the Chinese government has invested a large amount of financial funds since 2005 to launch a soil testing and fertilization project nationwide, aiming to achieve high yield, high quality and high efficiency of agriculture by guiding farmers to apply fertilizer scientifically and rationally.

The multiple effects of humic acid controlled by nitrogen, slow phosphorus release, potassium leaching and micronutrient activation are particularly important, which can greatly improve fertilizer efficiency and balance nutrient supply.

3.Humic acid is a good adjuvant for pesticides.

Humic acid foliar fertilizer as a good adjuvant for pesticides is mainly reflected in the following aspects:

(1) Humic acid is composed of complex organic matter, which contains more hydrophilic and lipophilic groups, has the function of surfactant, and is mixed with pesticides, which can effectively exert its good dispersion and emulsification. Improve pesticide activity and increase pesticide efficacy.

(2) Humic acid has a large specific surface area and has a strong adsorption effect on organic-inorganic substances. When it is compatible with pesticides, some complexes are formed, thereby releasing the effect of slow release of the drug.

(3) Because the amino acid and S-group in the functional group of humic acid can reduce the toxic effect of pesticides on humans and animals, the safety of pesticides after application can be improved to some extent.

(4) High-activity fulvic acid has solubilization and synergistic effect on pesticides, so that the amount of pesticides can be reduced to a certain extent, thereby correspondingly reducing the transfer of pesticides in the food chain and residues in the environment.

(5) Humic acid also contributes to the degradation of residual pesticides in the soil. Humic acid promotes the growth of microorganisms in the soil, while microorganisms can effectively degrade the residual pesticides in the soil, so it can effectively reduce the environmental pollution of residual pesticides after application. To reduce the penetration of pesticides into the food chain, thereby reducing the accumulation of pesticides in animals and plants.

In addition, humic substances themselves have a pesticide-like function. Studies have shown that after spraying humic acid foliar fertilizer, the incidence of pepper bacterial wilt, the incidence of flower rust, and the rate of rotten fruit are significantly reduced.
