Function of potassium humate

Function of potassium humate,let us start with humic acid functional group in potassium humate can absorb and store potassium ions, prevent loss with water in sandy soil and leaching soil, and prevent fixation of potassium by sticky soil.

In addition, some parts of potassium humate are low-molecular-weight humic acid such as fulvic acid, which has a corrosive effect on minerals such as potassium silicate and potassium feldspar, which can be slowly decomposed to increase the release of potassium and increase the content of available potassium.

The utilization rate is 87% -95% higher than ordinary potassium fertilizer, which increases fertilizer efficiency, crop yield and quality.
Potassium humate has a combination of land use and land cultivation; long-term and quick-effect coordination; special effects in water retention and fertilizer retention. It combines the advantages of inorganic fertilizers and farm fertilizers and is superior to them.

Function of potassium humate is a good controlled release fertilizer, so that the nutrients in the early stage will not be too much, the nutrients in the later stage will not be too low, and the fertilizer supply curve is stable. The release rate can also be controlled by physical and chemical biotechnology methods to achieve two-way regulation of accelerated release and sustained release.

The supply of nutrients in the fertilizer is basically synchronized with the nutrient requirements of the crop to achieve dynamic balance.
Ordinary chemical fertilizers (such as urea, 50% -60% potassium fertilizer, diammonium phosphate, etc.) can easily produce soil compaction and pollution to water and air, and potassium humate can be avoided or significantly reduced.

And it significantly increases crop yield, improves crop quality, improves crop nutritional content, reduces nitrate content, and has excellent color, fragrance, taste, and storability.

It is the material foundation of environmentally-friendly agricultural cleaner production and green food.

Potassium humate has low loss, high utilization rate, stable plant absorption, and two-way improvement in yield and quality..

Function of potassium humate,It is a “green” potassium fertilizer for agricultural applications and a substitute product for potassium chloride and potassium sulfate for general agricultural use. Potassium humate is suitable for any crop.

Potassium humate effect on crops

Potassium humate effect on crops

Potassium humate effect on crops has water retention, Drought resistance, cold resistance,Prevention and control of heavy metal pollution,Improve fertilizer efficiency,Promote the growth and development of crops, Adjust the soil pH.

1.water retention

Potassium humate is a colloidal organic substance, which can loosen the soil, absorb large amounts of water, ventilate and humidify, raise cockroaches, prevent drought, and make the soil have good water, gas and heat conditions, suitable for seed germination and seedling stage. Growing.
Second, improve saline-alkali land
Potassium humate has a small molecular weight and high activity. It can adsorb harmful cations in the soil, thereby reducing the concentration of salt in the soil, reducing the damage of salt to seeds and seedlings, and improving saline-alkali soil.

2. Drought resistance, cold resistance

Spraying potassium humate onto plant leaves can close the stomata of plants and reduce water transpiration of plants.

The color of humic acid potassium is deep, which is good for absorbing solar energy; when potassium humate is decomposed by the action of microorganisms, it will release heat, which can increase the ground temperature and thus play a role in cold resistance.
Fourth, resistance to pests and diseases

Potassium humate can increase the activity of enzymes in plants and increase the resistance of plant organisms.

3.Prevention and control of heavy metal pollution

Potassium humate participates in the ion exchange reaction in the soil, adsorbing and fixing the heavy metal ions in the soil to prevent them from entering the biological cycle.

4.Improve fertilizer efficiency

  • Nitrogen fixation: Nitrogen is applied to the soil and is easily volatilized into the atmosphere or lost to the river with water and soil. Potassium humate can adsorb nitrogen in the soil, reduce its volatilization and loss, and improve utilization.
  • Solution of phosphorus: Phosphorus is applied to the soil and is easily fixed by the soil. Potassium humate can liberate phosphorus from the soil by chelation with phosphorus, which is used for plant absorption and improves phosphorus utilization.
  • Activated potassium: Most of the potassium elements applied to the soil exist in the form of potassium salts and cannot be directly absorbed by the crops. Potassium humate can convert poorly soluble potassium into soluble potassium through ion exchange function, increase effective potassium in soil, and improve potassium utilization.
  • micro-fertilizer: potassium humate can chelate reaction with poorly soluble trace elements, and produce humic acid trace element chelate which is well absorbed by crops, which is beneficial to the absorption of trace elements in roots and leaves.

5. Promote the growth and development of crops

Potassium humate can stimulate root growth, and ultimately the ability of crops to absorb water and nutrients is greatly enhanced.

The stimulating effect of potassium humate can make the above-ground vegetative growth of plants flourish. Expressed in plant height, stem diameter, leaf thickness, etc.;

Potassium humate has a good effect on tilling and reducing the openness rate, which can increase the grain weight of grain and increase grain yield.

6. Adjust the soil pH

Potassium humate has more functional groups, which can be combined with acid and combined with alkali to adjust the pH of the soil according to crop needs.

Fulvic Acid

Fulvic acid

Fulvic acid, a short carbon chain small molecular structure material extracted from natural humic acid, is the water-soluble part of humic acid with the smallest molecular weight and the highest active group content, and is widely found in nature.

Among them, the proportion of fulvic acid in the soil is the largest, mainly composed of natural, yellow to dark brown, amorphous, gelatinous, organic polyelectrolytes with fat and aromaticity, with smaller molecular weight and highest active group content. Cannot be represented by a single chemical structure.

Fulvic acid is the best ingredient in soil humic acid.

It is also a humic acid product with a wide range of use and high economic benefits. It can increase grain yield, restore soil fertility, improve soil, improve ground temperature, promote root development, effectively adjust soil pH, solve soil compaction, reduce fertilizer application and increase The quality of agricultural products has special effects.

In the case of dry climate, it can reduce the degree of stomatal opening of crops, commonly known as “drought resistance No.1”. Up to now, there are still large market and competitive advantages in plant growth agents, anti-reverse agents, fluid fertilizers, pharmaceutical preparations and cosmetics.

Fulvic acid is a gray-black powdery substance that is soluble in water.

It is a plant growth regulator that promotes plant growth and plays an important role in combating drought. It can improve plant resilience, increase yield and improve quality. The main application objects are wheat, corn, sweet potato, millet, rice, cotton, peanut, rape, tobacco, sericulture, melon and fruit, and vegetables.

Fulvic Acid Structure

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.

Beijing Carbon Source Power potassium humate is a rare and good product.

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, humic acid can also 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

Humic acid 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, studies have shown that humic acid can inhibit the germination of downy mildew sporangia, and compounding with other pesticides can significantly reduce the occurrence of downy mildew. At the same time, humic substances can also enhance the control of root-knot nematodes.

Phytic acid is widely used in pesticide additives due to its special structure and function. It also proves that humic acid has a good effect on plant disease resistance.

Humic acid is an important component of organic matter, which can reduce the application of fertilizer, improve the efficiency of nutrient use, partially replace the biosynthesis plant growth regulator, improve the quality of fruits and vegetables, improve the resistance of plants, reduce the occurrence of pests and diseases, and promote the early development of plants.
