Under drought conditions, the application of potassium humate-containing fertilizer can promote the increase of proline content in plant leaves, promote the water-holding capacity of cells, and increase the activity of plant cell protective enzymes (nitrate reductase, superoxide dismutase, Oxidase, etc., reduce the permeability of the plasma membrane, etc. to comprehensively improve the drought resistance of crops.

Plant salt and alkali stress

Humic acid substances can indirectly improve the stress tolerance and stress resistance of plants by improving the physical and chemical properties of the soil. In addition, potassium humate can also be used to enhance the salt resistance of the material membrane under salt stress by regulating the change of fructose concentration.

Plant temperature stress

Under low temperature stress, potassium humate can increase the proline content and abscisic acid content of crops, increase the activity of polyphenol oxidase, and reduce the decrease of transpiration rate, stomatal conductance and net photosynthetic rate of plants after low temperature stress. Its cold resistance.

Under high temperature stress, potassium humate also performed well. The activities of crop superoxide dismutase and peroxidase are increased, the rate of superoxide anion production and the content of hydrogen peroxide are reduced, and the heat resistance of crops is enhanced.

Plant heavy metal stress

Humic acid contains a variety of functional groups, which can fix heavy metals on the surface of soil particles through complexation, chelation and reduction, thus affecting their migration and reducing the solubility of heavy metals in water and reducing their toxicity.

At the same time, potassium humate can alleviate the toxic effect of heavy metal cadmium on seedlings. The main mechanism is to inhibit the absorption of cadmium and promote its absorption and accumulation of nutrients such as copper, zinc, iron and manganese.

Plant disease resistance

Potassium humate can promote growth by increasing the sugar content and chlorophyll content of leaves, which indirectly improves the disease resistance of crops. At the same time, humic substances can also enhance the control of root-knot nematodes.

Potassium humate is an important component of organic matter, which can reduce the application of fertilizer, improve the efficiency of nutrient use, partially replace bio-synthesized plant growth regulators, improve the quality of fruits and vegetables, improve the resistance of plants, reduce the occurrence of pests and diseases, and promote early planting. Hair and flowering, the function is very powerful, and it should be widely used.

The soil is the loose surface of the earth’s land that can grow plants. Fertility is the basic property of the soil. There are many basic traits affecting fertility, including: the thickness of soil tillage layer; the texture and structure of ploughed soil: soil organic matter content; nutrient content of soil nitrogen, phosphorus and potassium; soil acidity and alkalinity.

Acidification is an important aspect of soil weathering and soil formation, resulting in lower pH, acid soil formation, affecting the activity of soil organisms, changing the form of nutrients in the soil, reducing the availability of nutrients, and promoting the dissolution of free manganese and aluminum ions into the soil. In the solution, it has a toxic effect on the crop. Generally speaking, the severity of soil acidification is expressed by PH value, such as PH value = 4.5 acidity; PH value = 4.5-5.5 strong acid; PH value = 5.5-6.5 acid.

What are the hazards or side effects of soil acidification on crops?

  1. Affect the absorption of nutrients by roots
    Generally, acidified soil is relatively hard, and the knotting phenomenon is relatively serious. This will make the elongation of the root system difficult, and the area of ​​root formation will decrease. This will cause the absorption capacity of the root system to decrease, the growth of the plant is weak, and the yield and Quality will not be satisfactory. In addition, plants with weak growth are more susceptible to disease and are prone to disease.
  2. Poisoning occurs
    Under acidic conditions, the solubility of some acidic ions (such as aluminum, manganese, etc.) will increase, which will have some toxic effects on crops. At the same time, there are many hydrogen ions in the acidic soil, so it will antagonize some of the cations required by the plants in the soil, affecting its absorption and utilization.
  3. Reduced absorption of elements
    The acidic soil environment will cause a large loss of nitrogen, and at the same time, some elements will be fixed, so the elements in the soil for plant absorption and utilization are reduced. This is the aforementioned “the greater the amount of fertilizer applied, the more the crop grows. One of the reasons for the difference.
    At present, in the domestic cultivated soil, the fertility level is low, the soil physical and chemical properties are poor, and the low-yield soil with low crop yield is about 30%. The basic traits of these soils can be summarized as: “dry, alfalfa, salt, alkali, acid, board, thin”. Reconstructing low-yield soils has made it important for agriculture to achieve balanced production and accelerate agricultural modernization.

Beijing carbon source power humic acid potassium is an organic combination of microorganisms and high-quality humic acid, and the product has high activity and obvious effect. The main function:

  1. Potassium humate improves soil structure, promotes the formation of aggregates, coordinates soil water, fertilizer, gas and heat, and can not only ventilate, but also retain water and not compact.
  2. Potassium humate enhances soil fertility and fertilization capacity, maintains strong fertility, reduces effective nutrient loss, and provides long-lasting fertilizer, making the fertilizer efficiency of various quick-acting fertilizers “slow, fierce and short” become “slow and stable” ,long”.
  3. Potassium humate improves soil acidity and alkalinity and reduces side effects of toxic factors.
  4. Potassium humate promotes rooting and improves root water absorption capacity. Kejia’s highly active humic acid is used for root irrigation or irrigation with water droplets. The roots of the crops are fast, the number of roots is increased, the root weight is increased, and the roots are able to absorb nutrients. .
  5. Potassium humate enhances the stress resistance of crops. The humic acid crops are resistant to cold and drought, and the disease resistance is significantly enhanced.

How is soil acidification caused?
Excessive consumption of soil nutrients
With the advancement of technology, the output of crops can be said to be a rapid increase, which will result in a significant increase in the demand for nutrients in the crops, and generally a piece of land we plant all the year round, so it will cause a lot of elements to be After the plant is absorbed, it does not promptly rehabilitate or rotate, resulting in the soil becoming more and more barren, while the barren soil is generally more acidic.

  1. Unreasonable fertilizer application
    The soil is poor, and farmers generally think of applying fertilizers to solve the problem of insufficient soil nutrients to ensure annual production. However, when applying fertilizer, a large amount of acidic fertilizers, such as potassium chloride, ammonium sulfate and the like, ammonia fertilizer, etc., are applied, and the application of these fertilizers will deposit in the soil, thereby aggravating the acidification problem of the soil, and chemical fertilizers. A large amount of application will also affect the content of organic matter in the soil, and the amount of organic matter directly determines the buffer capacity of the soil and the strength of resilience.
  2. Organic supplements are not timely
    Generally speaking, when you apply a large amount of chemical fertilizers, the organic matter content in the soil will be affected relatively, so we should supplement it according to the soil conditions in time to ensure the normal buffer capacity and recovery ability of the soil.

The call for remediation of soil has never stopped. The problem of life is always ignored by people. It may even feel that a series of problems are caused by the destruction of the soil. It is far away from us; in fact, the soil has developed into a national value and affects personal life. The height of life safety. For example, crop root growth caused by soil compaction is caused by yin and susceptible disease, and crop cropping phenomenon caused by severe acidification of soil. Multi-watering and multi-purpose fertilizer can not solve these problems. The more water and fertilizer are not. The better, “Green Mountain Qingshan is Jinshan Yinshan” “The beautiful factor of humic acid is the gold dollar silver dollar”, how to achieve the weight loss and efficiency of the humic acid potassium in Beijing, and repair damaged soil to promote healthy growth of crops?

Potassium humate is a non-uniform aromatic hydroxycarboxylate with a black granule or powdery solid. It is a product obtained by finely selecting lignite and then extracting it with KOH liquid. It is soluble in water and alkaline. It contains an active group such as a carboxyl group or a phenolic hydroxyl group.

The humic acid functional group in potassium humate can absorb potassium ions, prevent water loss in sandy soil and leaching soil, and prevent potassium from sticking in sticky soil.

In addition, some parts of potassium humate are low-molecular humic acids such as fulvic acid, which have a dissolution effect on minerals such as potassium silicate and potassium feldspar, which can slowly decompose to increase the release of potassium and increase the content of available potassium.

It is 87%–95% higher than the common potassium fertilizer utilization rate, which increases fertilizer efficiency, improves crop yield and improves quality.

It has the special effects of combining land and land; long-acting and quick-acting coordination; water-retaining and fertilizer-retaining effects.

It combines the advantages of inorganic fertilizer and farmyard manure and is superior to them.

It has a good nutrient release regulation function. It is a good controlled release fertilizer, so that the nutrient is not too much in the early stage, the nutrient is not too low in the later stage, and the fertilizer supply curve is stable.

The release rate can also be controlled by physical and chemical biotechnology to achieve two-way regulation of sustained release and sustained release.

The balance between the supply of nutrients in the fertilizer and the demand for nutrients in the crop is basically synchronized to achieve a dynamic balance.

Ordinary chemical fertilizers (such as urea, 50% – 60% potassium fertilizer, diammonium phosphate, etc.) are easy to produce soil compaction and water and gas pollution, potassium humate can be avoided or significantly reduced. And obviously high crop yield, improve crop quality, improve crop nutrient content, nitrate content, color, aroma, taste and storability.

It is the material basis for agricultural clean production and green food with environmental protection functions. The loss of potassium humate is low, the utilization rate is high, the plant absorption is stable, and the yield and quality are improved in both directions.

It is a “green” potash fertilizer for agricultural application and a substitute for ordinary agricultural potassium chloride and potassium sulfate. Potassium humate is suitable for any crop and can also be applied in combination with common fertilizers.

  • Potassium humate can improve soil physical characteristics, improve soil aggregate structure, reduce soil compaction, and achieve good conditions.

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. It shows how important the soil is to the growth of everything! 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.

The humic acid foliar spray is a good auxiliaries for pesticides, 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 and humic acid 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.

Potassium Humate Application
Application of potassium humate in saline-alkali soil

Potassium Humate Application in China’s saline-alkali soil is mainly distributed in the northwest, north China, northeast and coastal areas, including salt soil and alkaline soil. The saline soil mainly contains a large amount of soluble salts, including sodium chloride and sodium sulfate, and the pH value is 8-9. Alkaline soil mainly contains sodium carbonate, sodium hydrogencarbonate, pH 9~10, and is strongly alkaline.

The main hazards of saline-alkali soil: the soil salt content is too high; the concentration of harmful ions (such as Na+, Cl-, HC03-, CO22-, Mg2+, etc.) is too large; the soil is too alkaline; the soil particles are highly dispersed, and the soil structure is poor; Crop growth and development is inhibited.
Long-term application of potassium humate can gradually change the physical and chemical properties of saline-alkali soil.

First, promote the formation of soil aggregate structure


The soil aggregate structure is the basic unit of soil structure. It is a large soil particle composed of organic and inorganic colloids such as soil humus and clay. Good agglomerate structure is not easy to disperse when it is in contact with water. It is not easily broken by mechanical pressure, loose and porous, and can regulate the water, fertilizer, gas and heat of the soil.

As an organic colloid, long-term application of potassium humate can promote the formation of soil aggregate structure, improve the soil structure, and make the soil a good aeration and water permeability. It has created favorable conditions for accelerating the elution of soluble salts and root growth. .

For example, after soda-salted paddy soil in Miquan County, Xinjiang, the content of water-stable aggregates in the soil greater than 0.25 mm was significantly higher than that in the soil without potassium phytate. Other properties such as soil air content, water permeation rate, and redox potential are improved.

Second, reduce the amount of salt in the topsoil

The concentrated application of potassium humate can loosen the soil of the ploughed soil, destroy the conditions of the salt along the pores of the soil capillary, increase the accumulation of salt in the topsoil, and reduce the salt content of the topsoil, which plays a role of “separation of salt”.

The spring wheat experiment in Zhangbei County of Hebei Province showed that in the concentrated ditch sulphate potassium (100 kg/mu), the total salt content in the topsoil of 0~125px was reduced by one-third compared with the non-application, and the ion concentration also decreased significantly.
Due to the “salting salt” effect of potassium humate, the damage of salt and alkali to crop seedlings can be alleviated, the emergence rate can be improved, and weak seedlings and dead seedlings can be reduced. Zhangbei County applied humic acid potassium to spring wheat. The basic seedlings were more than 54,000 per mu, and the emergence rate was 20% higher.

Third,Potassium Humate Application to improve soil exchange capacity

Potassium humate has a high cation exchange capacity, which is more than 10 times higher than that of ordinary soil. After being applied to the soil, the adsorption capacity of the soil for Ca2+, Mg2+ and other divalent cations is significantly improved. Under the condition of proper water leaching, the leaching rate of Na+, Cl-, etc. in the soil solution is accelerated accordingly. The surface salt content is gradually reduced, and the salt composition changes significantly.
The Xinjiang Institute of Biological Soil and Desert Research applied potassium humate for two consecutive years on soda-salted paddy soil. The surface CO-, HC03-, and Cl- contents decreased, and the degree of sodium alkalinity decreased.

Fourth,Potassium Humate Application to reduce the pH of salt reduction soil (pH value)

The pH value of saline-alkaline soil, especially alkaline soil, is too high (above 9.0), which directly harms the growth of crops and even causes crop death. In addition, the pH value is too high, which also affects the availability of nutrients such as phosphorus, iron, manganese, boron and zinc in the soil.

On the alkaline alkaline soil, the acid raw coal powder or potassium humate is applied, and the humic acid can neutralize the alkali to lower the soil pH. The experimental results show that the application rate of acid weathered coal powder is 10% of soil weight, which can reduce the soil pH from 9.0 to 8.0, and reduce or eliminate the soil alkalinity.

The application of humic acid can improve soil physical and chemical properties, inhibit salt rise, neutralize soil alkalinity, reduce salinity hazard by adsorption of cations, create good soil conditions for crop seedling growth, and improve low-yield saline-alkali soil.

Humic acid increases NPK utilization and increases plant nutrition

Humic acid increases NPK utilization ,For nitrogen: Since humic acid has a salt exchange capacity many times higher than soil, it can adsorb a large amount of ammonium ions to reduce the loss; at the same time, humic acid has a good inhibitory effect on urease and nitrifying bacteria, and can greatly increase urea. Sustained release and use efficiency.

Humic acid increases NPK utilization ,Phosphorus: It can react with the fixed phosphate fertilizer in the soil to convert it into effective phosphorus; it has a protective effect on phosphorus, can improve the utilization rate of phosphate fertilizer in the current season; it can also improve the mobility of phosphorus, which is DAP/MAP, etc. Effective additives.

For potassium: It has a strong adsorption effect on K+, which can reduce the loss; it has a certain dissolution effect on potassium-containing minerals such as potassium silicate and potassium feldspar, thereby increasing the effective potassium content in the soil.

2. humic acid can improve soil aggregate structure, ph, modulating heat, microbial growth, pollution reduction – the environment

It can improve the structure of soil aggregates: the colloidal properties of humic acid have good adhesiveness, which is beneficial to the formation of more and better soil aggregate structure.

Adjusting the pH of the soil: Since humic acid is a multi-weak acid, it has a strong buffering property, so it can play a role in mediating the pH of the soil, and then convert nutrients and trace elements into a form that can be absorbed by plants.

Dimming heat: Since humic acid has a deep black color, it is equivalent to laying a black mulch on the soil after being applied to the soil, which improves the photothermal performance of the soil and is beneficial to increase the ground temperature.

Improve bacterial activity: In the soil of the compacted soil, humic acid can interact with beneficial bacteria in the soil to make the soil a soft structure and promote the absorption of water nutrients and oxygen by plants.

Reduce heavy metal pollution: In acidic soil environments, humic acid reacts with heavy metals to reduce heavy metal pollution.
