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.

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 humic 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.

Abnormal climate, high environmental protection, negative growth of national pesticides and fertilizers, and organic fertilizers instead of large chemical fertilizers, agriculture calls for efficient and environmentally friendly production materials; soil environment is deteriorating, crops are physiologically dysfunctional, agricultural products are generally poor in quality, and supply ends need to be in quality and quantity. Kungfu can meet the requirements of the demand side.

The source of humic acid, especially the source of potassium humate, has been recognized and advocated by the state for its magical effects in solving crop physiological obstacles, improving the quality of agricultural products, and improving weight gain by its safe, ecological, micro-efficient and powerful integration effects. A strong sense of experience has also been favored by growers, especially high-end cash crop growers.
 
The reason why humic acid has received such widespread attention is mainly based on two factors: First, the external environment. The current policy orientation and demand of the country have forced humic acid production enterprises to pay more and more attention to the research and development, application, service and promotion of humic acid products. The second is its own factor. Mineral humic acid has a unique competitive advantage over other biostimulants. First of all, the source of humic acid is very wide, and its raw material lignite and weathered coal are abundant in China, and the supply of raw materials is guaranteed.

Secondly, humic acid is easy to achieve industrialization and large-scale production, and is stable, safe and reliable. Again, the integration effect of ore source humic acid is strong. The special molecular structure gives humic acid unique advantages in function. The effects of improving soil, stimulating crop growth, improving crop stress resistance, improving quality, and slow release of fertilizers are excellent.

It is said that the source of potassium humate is very magical. Is there any magic in it? Which fields are suitable for the application of the source of potassium humate ?
1. Soil: The acid, alkali, salt, compaction, heavy metal exceeding the standard and low soil organic matter in the soil can be used as the source of potassium humate.
2.Fertilizer: mineral source humic acid on fertilizer synergy is mainly reflected in improving fertilizer utilization, weight loss and efficiency.

The volatilization, loss and fertilizer efficiency of nitrogen fertilizer are short: mineral humic acid can complex nitrogen fertilizer and reduce the volatilization and loss of nitrogen fertilizer; ore source humic acid is a natural urease inhibitor, which can inhibit soil urease activity and prolong nitrogen fertilizer efficiency.
   
Laziness and antagonism of phosphate fertilizer: Phosphorus is lazy and has a short moving distance. Mineral source humic acid can increase the moving distance of phosphorus, increase the contact with roots, increase the utilization of phosphorus, and antagonize multiple elements such as phosphorus and calcium and magnesium. It is fixed by metal ions in the soil to convert the available phosphorus into delayed phosphorus or ineffective phosphorus. Humic acid can liberate the immobilized phosphorus element, making it a soluble phosphorus, increasing the activity of phosphorus.
    
Potassium protection: Humic acid can absorb and store potassium ions, which can prevent potassium ions from being lost with water in sand, prevent potassium fixation in sticky soil, and improve potassium utilization

3.Crops: Ore source humic acid can solve crop physiological obstacles and improve the quality of agricultural products. The root system is weak, the growth potential is poor, the resistance is poor, the physiological yellowing, the color change is slow, the expansion is slow, the sugar content is low, and the smoothness is poor. The source of potassium humate can be used.

The most important feature of microorganisms is their small size, variety, rapid reproduction and strong environmental adaptability. Microorganisms are widely distributed in nature.

However, the place where the most microorganisms are concentrated is the soil, which provides various basic elements for the growth of microorganisms, and also has the advantages of good heat preservation performance and strong cushioning property. Therefore, soil is the base of microorganisms and is the most abundant of human beings. Strain resource library.

The most bacteria in the soil, accounting for 70-90% of the total amount of soil microorganisms. Different types of bacteria in the soil have different effects. Some can fix the nitrogen in the air, synthesize the protein in the cells; some can break down the straw of the crops, most of them are heterotrophic bacteria. In addition to bacteria, other microorganisms in the soil are more actinomycetes (the main producing bacteria of antibiotics) and fungi, while algae and protozoa are less.

Soil microbes are important factors in soil fertility. Microorganisms are a large-area system with a huge nutrient absorption surface, excretion surface of metabolic waste, and exchange surface of environmental information. Therefore, it absorbs more and transforms faster, providing high-speed growth and reproduction of microorganisms and synthesis of a large number of metabolites. Material basis.

The natural world is rich in materials and diverse in variety, providing abundant food for microorganisms. Microorganisms have diverse nutrient types and metabolic pathways, from inorganic nutrition to organic nutrition, which can make full use of natural resources; respiratory type diversity, which can live in aerobic environment, anoxic environment, and even anaerobic environment. Environmental diversity such as extreme heat, high salinity and extreme pH creates a wide variety of microorganisms and large quantities.

The soil contains a variety of organic and inorganic nutrients. It is a natural medium for microbial growth and development. The soil is extremely rich in microbial species. There are 2.5 billion bacteria, 700,000 actinomycetes, and 400,000 in 1g of cultivated soil. Fungi, 50,000 algae, 30,000 protozoa.
Most microorganisms multiply progeny by fission, and under suitable environmental conditions, they can be propagated for ten to twenty minutes. Most of the microorganisms are single cells, and the structure is simple. The whole cells are directly in contact with the environment, and are susceptible to environmental factors, causing changes in the DNA of the genetic material.

Microbial fertilizers are products that cause specific fertilizer effects on crops due to microbial life activities. They are screened from the soil and domesticated to improve the nutrition of crops.
It includes autonomous or symbiotic nitrogen-fixing bacteria that fix molecular nitrogen in the air and convert it into plant-usable nitrogen; in the soil, phosphorus and potassium that cannot be utilized by mineral plants are converted into effective phosphorus and potassium microorganisms, namely phosphorus. Bacterial and potassium bacteria; and plant root ring-promoting bacteria that secrete a variety of stimulants and antibiotics for beneficial crop growth.

Microbial research has a wide range of applications in agriculture:
Environmental aspects: Microorganisms can repair soil, restore soil vigor, reduce heavy metal pollution, and not cause secondary pollution. Microorganisms can also purify water and remove toxic gases from the air.

Crop growth: Microorganisms can promote the absorption of nutrients by crops, promote the growth of crops, and improve the immunity of crops. These do not pollute the environment and agricultural products like chemicals and hormones.

Humic acid: Humic acid is a major advancement of organic fertilizer, and has many advantages over chemical fertilizers and farmyard manure.

Organic matter is not necessarily humic acid, but humic acid must be the best organic matter! Soil organic matter deficiency is the main factor inhibiting microbial activity. The application of carbon source power source humic acid as a supplement to soil organic matter, one is to the soil only It is suitable for the living environment of beneficial microorganisms.

Secondly, the microorganisms can secrete nutrients of various beneficial crops by decomposing the organic matter in the soil, and can promote the comprehensive utilization of soil organic and inorganic nutrients, thereby fundamentally reducing the amount of fertilizer and reaching humic acid. The role of weight loss and synergy. Humic acid is the original material of the soil.

The application of humic acid can activate the microbial activity of the soil, and further repair the soil to achieve the purpose of healthy growth of the crop!

The effects of fulvic acid on soil, fertilizers and plants in the agricultural sector are:

Improve soil Improve soil aggregate structure.

The fulvic acid is a humic 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 content of granules ≥ 0.25 mm in the soil is increased by 10-20%, and the content of organic matter is increased by 10%, so that the soil can maintain moisture. Increase ventilation, which is conducive to the growth of crops.

Enhance the water retention of the soil.

Fulvic acid 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 be more than doubled, which is much larger than that of ordinary mineral colloid. The fulvic acid inhibits the transpiration of the crop, so that the soil water consumption rate is slowed down and the soil water content is correspondingly increased.

Enhance the fertility of the soil.

The fulvic acid itself is an organic acid, which increases the dissolution of the mineral part of the soil, provides soil nutrients, and increases the effectiveness of nutrients through complexation. As an organic colloid, fulvic acid has positive and negative charges, which can adsorb anion and cation, so that these nutrients can be stored in the soil, not lost with water, and improve the utilization rate of fertilizer, which is especially important in sandy land.

Adjust the pH of the soil solution.

The fulvic acid and the fulvic acid salt transform each other to form a buffer system, thereby regulating the pH of the soil solution.

Reduce soil salinity.

The colloidal structure formed by the complexation of fulvic acid and chelated metal cations in the soil and its porosity (larger specific surface) can adsorb ions or molecules in the soil solution and reduce the concentration of salt in the soil solution.

Biological action fulvic acid 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 group and phenolic hydroxyl group in fulvic acid have certain Inhibit the role of the virus.

Improve fertilizer utilization.

fulvic acid contains carboxyl, phenolic hydroxyl and other functional groups, has strong complexation, chelation and surface adsorption capacity, can reduce the loss of ammonium nitrogen; increase the movement distance of phosphorus in the soil, inhibit soil water solubility The fixation of phosphorus can convert the ineffective phosphorus into effective phosphorus and promote the absorption of phosphorus by the root system.

The fulvic acid can absorb and store potassium ions, and the effective potassium content, especially the potassium fertilizer, is especially effective. Experiments show that fulvic acid can increase the utilization rate of nitrogen, phosphorus and potassium nutrients in fertilizers by more than 20%.

Slow release synergistic effect of pesticide

fulvic acid has a surfactant function, can reduce the surface tension of water, emulsification and dispersion of pesticides; fulvic acid as a colloidal substance with a large viscosity and surface area may produce pesticides Strong physical sucking effect; fulvic acid itself has antibacterial and anti-disease effects, and the compounding with fungicides is equivalent to the compounding of two pesticides.

The stimulation of plant growth

fulvic acid similar to plant endogenous hormones, can promote seed germination, root growth, fruit coloring early maturity. Specific manifestations: promote root growth and activity, similar to auxin effect; promote seed germination, emergence of seedlings and seedling growth, similar to the effect of gibberellin; make leaves enlarge, thicken, green, delayed senescence of lower leaves, similar The role of cytokinin; the reduction of stomatal, transpiration, similar to the role of abscisic acid; the fruit coloring, maturation, similar to ethylene ripening; promote cell division and cell elongation, differentiation, etc., similar to two The role of the above plant hormones.

Improve the quality of agricultural products

fulvic acid enhances the synthesis of sugar, starch, protein, fat and various vitamins. It can stimulate the activity of polysaccharide enzyme, convert polysaccharide into soluble monosaccharide, thereby improve fruit sweetness; increase the ratio of total sugar to nicotine and potassium to chlorine in tobacco leaves, improve the quality of tobacco leaves; increase the total content of watermelon, cantaloupe and other fruits Sugar content and vitamin C content.

Enhance the stress resistance index of crop stress-resistant plants

(one): the content of ABA (abscisic acid: a plant hormone that inhibits growth) in plants. The ABA content of plants will increase under any adverse conditions. Abscisic acid is the “first messenger” that initiates the expression of stress-resistant genes in plants, and effectively activates the anti-reverse immune system in plants. Physiological mechanism of fulvic acid to improve plant stress resistance (common): fulvic acid can increase the content of ABA in plants.
