The efficacy and application of potassium humate
Humic acid is a macromolecular organic substance widely found in nature. It is widely used in agriculture, forestry, animal husbandry, petroleum, chemical, building materials, medical and health, environmental protection and other fields, spanning dozens of industries. In particular, it now advocates ecological agriculture construction, pollution-free agricultural production, green food, pollution-free environmental protection products, etc., and makes “humic acid” highly respected. It turns out that human life and survival are inseparable from humic acid. It is indeed a The promising sunrise industry in development belongs to a new type of special industry.
Chinese name: potassium humate
Chinese alias: humic acid potassium; humic acid potassium,
English name: Potassium humate, humic acids potassium salts;
English alias: Humic acid potassium salt; Humic Acid Potassium; Humi acids, potassium salts
Chinese custom abbreviation: HA-K.
Potassium humate is a high-efficiency organic potash because humic acid is a biologically active preparation that increases soil available potassium content, reduces potassium loss and fixation, increases potassium uptake and utilization by crops, and improves soil. It can promote crop growth, improve crop resilience, improve crop quality, and protect agricultural ecological environment; it can be combined with urea, phosphate fertilizer, potash fertilizer, trace elements, etc., and can be made into high-efficiency multifunctional fertilizer; in addition, humic acid Potassium can also be used as a treatment agent for oil drilling fluids, mainly to prevent collapse of the well wall.
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.
Potassium humate significantly increases crop yield, improves crop quality, improves crop nutrient content, reduces nitrate content, and has excellent 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 is non-toxic, odorless, black natural organic powder. Soluble in water, it is a kind of organic macromolecular compound with a large number of intricate functional groups. It is more resistant to microbial decomposition. Its slowing down is the crown of all organic solid fertilizers. It has strong adsorption, exchange, complexation and chelation. Ability is the best indicator of fertility, and it is also known as ecological fertilizer. It can be used as an organic fertilizer for slow-acting nitrogen, phosphorus and potassium. It can also provide a large amount, medium amount and trace elements required for various plants, and organic substances including humic acid, yellow rot, humic acid amino acid, sugar and the like. High-quality potash fertilizer and organic raw materials in the production of organic compound fertilizer.
Function and efficacy
1) Potassium humate v It can improve soil physical characteristics, improve soil aggregate structure, reduce soil compaction and achieve good condition; 2) Increase soil cation exchange capacity and fertilizer retention capacity to adsorb and exchange plant nutrients, improve fertilizer slowness and increase soil 3) The ability to provide soil-friendly microbes; 4) Promote the decomposition of man-made (such as pesticides) or natural toxic substances and effects; 5) Increase the soil’s ability to balance and neutralize soil pH; 6) Color black It can help absorb heat and plant in early spring; 7) directly affect cell metabolism, improve crop respiration and photosynthesis, and enhance crop resilience, such as drought resistance, cold resistance, disease resistance, etc.; 8) release of plants after decomposition Nutritional elements; 9) Strong roots increase yield, improve crop quality and increase sweetness.
