Potassium humate and fulvic acid are particularly interesting because they both contain molecular structures of polar and non-polar substituents, so they can transport both water-soluble and water-insoluble species. Indeed, colloidal organics.

For example, soluble humic acid and fulvic acid found in groundwater and surface water are called “third stage” in the traditional two-stage. Solid and water phase systems are used for hydrochemical modeling. Because potassium humate and fulvic acid in the colloid size range are key factors in chemical waste migration and other hydrological processes
A process that can produce enough humus and yellow rot material like fulvic acid.

Sampling methods. Chemical and physical characteristics change with size are necessary for improvement. Our understanding of their role in hydrogeochemistry. Classic method for separating potassium humate and fulvic acid from soil and water. The pH is about 2.

Many studies have attempted to remove metals from humus and treated fulvic acid with hydrochloric acid and hydrogen fluoride. These methods are because strong chemical treatments will change the chemical structure of humus and fulvic acid through acid-catalyzed reactions (decarboxylation, degreasing, etc.) and cause physical changes in shape (hence effective diameter). Other methods to minimize.

Including radionuclides and toxic metals in their natural geochemical state) A method of sampling and sizing of potassium humate, fulvic acid and other humic acids.

Organic and inorganic colloidal materials from groundwater or surface water can be reproduced with minimal artifacts (chemical and physical artifacts). The method should be suitable for processing a large amount of water to obtain sufficient materials for multiple analytical procedures (infrared, C-NMR, pyrolysis, chromatography, mass spectrometry, etc.) Methods should also be relatively simple and easy to use, and easy to use in the laboratory, especially in outside.

Potassium humate enhances 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.

The standard oxidation-reduction potential (E0) of potassium humate is about 0.7 V, which is equivalent to the electrode potential of the semiquinone radical. Therefore, it is considered that the redox property of potassium humate is caused by the mutual conversion of -semiquinone-phenol. In fact, the carbonyl, alcoholic hydroxyl, amino, nitro, and even fatty carbon structural sites in potassium humate may participate in the redox reaction.

This property of potassium humate not only regulates the redox concentration ratio of soil minerals (αOx/αRrd), stimulates microbial activity, regulates the physiological activity of plants, but also changes in geochemistry, heavy metals and organic poisons (oil, polycyclic The migration and toxicity of aromatic hydrocarbons, phenols, dyes, pesticides, etc. also have an effect.

Experiments show that the presence of potassium humate can keep the effective oxidation-reduction potential (Eh) of the soil environment in the optimal range (0.2~0.7V), which is conducive to crop growth and development.
Potassium humate can activate synthetases (aldolase, invertase, etc.) in plants, regulate oxidase activity, and protect auxin, which is the basic reason for improving plant stress resistance.

  3. (2) Improve the activity of SOD (superoxide dismutase) and CAT (catalase) to scavenge free radicals, reduce the damage of membrane lipids, delay the senescence of plants, and make the life activities of crops less affected by drought. It can be carried out more normally.

2.Cold resistance mechanism

Potassium humate can increase the content of abscisic acid in plants, and abscisic acid can increase the content of proline. Proline, as an important osmotic regulator, can stabilize the structure of biological macromolecules, so that the freezing point can be frozen and protect the plants. Cold resistance.

3.Disease resistance mechanism

The mechanism of antibacterial and anti-disease of potassium humate:

Potassium humate contains a variety of benzene carboxylic acids, which can produce limited immunity to certain diseases of plants: Zhang Dehe and others have been from the sulfurized coal humate potassium in Turpan, Xinjiang. 17 low molecular weight polyphenylene acids and phenolic acids were isolated and identified, and these compounds are likely to be disease-inducing agents with different induction effects.

(1) Potassium humate directly increases the soil organic matter content, provides an excellent environment for beneficial microorganisms, and the beneficial population gradually develops a dominant population, inhibits the growth of harmful bacteria, and the plant itself grows robust due to excellent soil conditions. The ability to strengthen the disease, thus greatly reducing the disease, especially the occurrence of soil-borne diseases.

(2) Potassium humate makes the number of aerobic bacteria, actinomycetes and fiber-decomposing bacteria in the soil increase more, the number of fungi is significantly reduced, the ratio of bacteria to fungi is obviously increased, and many fungi can be prevented disease.

(3) Potassium humate contains a phenolic type such as a carboxyl group or a phenolic hydroxyl group and a benzene carboxylic acid structure, which is the same as the active components of some phenoxycarboxylic acids and phenolic pesticides, and has a certain antibacterial and antiviral action.
