Improved soil

Improve soil aggregate structure. Potassium humate is a humic substance that affects the properties of the soil and promotes the formation of a more stable agglomerate structure in the soil, which increases the content of aggregates ≥ 0.25 mm in the soil by 10-20%, and increases the organic matter content by 10%. Increase ventilation, which is conducive to the growth of crops.

Enhance the water retention of the soil.

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 be more than doubled, which is much larger than that of ordinary mineral colloid. Potassium humate inhibits crop transpiration, slows the rate of soil water consumption, and increases soil water content.

Enhance the fertility of the soil.

Potassium humate itself is an organic acid that increases the dissolution of mineral parts of the soil, provides soil nutrients, and increases the effectiveness of nutrients through complexation. As an organic colloid, potassium humate 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.

Potassium humate and humate transform each other to form a buffer system that acts to regulate the pH of the soil solution.
Reduce soil salinity. The colloidal structure formed by complexation of potassium humate and chelation of 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.

Potassium humate 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 crop stress resistance

Plant stress resistance index (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 potassium humate to increase plant stress resistance (common): Potassium humate can increase the content of ABA in plants.
Potassium Humate: As a plant growth regulator, it is the best component of soil humus, which not only reduces crop burden, increases soil fertility, enriches the matrix of soil bacteria, but also improves crop yield and quality. Agriculture achieves the long-term development goal of increasing production, upgrading and raising land. To solve the problem of crop quality, so it is agricultural ginseng!

Stimulate the role of growth metabolism.

Potassium humate contains a variety of active functional genes, which can enhance the activity of catalase and polyphenol oxidase in crops, stimulate physiological metabolism and promote growth and development.

For example, potassium humate can promote early germination of seeds, and the emergence rate is high, especially at low temperatures; it can stimulate the division and growth of root meristem cells, so that the roots of the seedlings are fast, the roots are increased, the roots are increased, and the roots are elongated. To increase the ability of crops to absorb water and nutrients.

Change the characteristics of fertilizers.

Potassium humate contains carboxyl, phenolic hydroxyl and other functional groups, has strong ion exchange and adsorption capacity, can make ammonium bicarbonate reduce the loss of ammonium nitrogen, and improve the utilization rate of nitrogen fertilizer. Inhibits urinary enzyme activity and reduces urea volatilization.

Increase the distance of phosphorus movement in the soil, inhibit the fixation of water-soluble phosphorus in the soil, convert the available phosphorus into delayed-effect phosphorus, and promote the absorption of phosphorus by roots.

Potassium humate functional group can absorb potassium ions, slow down the potassium fertilizer, increase the release of potassium, and increase the content of available potassium. Humic acid and insoluble trace elements can undergo a kneading reaction to form a humic acid trace element chelate which is well soluble and can be absorbed by crops, thereby facilitating the absorption of trace elements by roots and leaves.

Potassium humate is a residue of plants and animals (brown coal, weathered coal, peat) formed by tens of millions of years of soil microbial transformation.

The source of potassium humate is rich in various functional groups such as hydroxyl group, phenol group and carboxyl group, and the utilization rate is high.

Potassium humate can regulate soil pH due to its functional group. It is also a natural chelating agent, which chelate with metal ions to reduce nutrient loss or solidification and promote direct absorption of plants.

It can promote poorly soluble aluminosilicates in soil. Inorganic minerals (Phosphorus and Potassium) form soluble nutrients and are directly absorbed and utilized by plants.
