Five functions of mineral potassium fulvicate
1. Promote the development of crop root systems and increase the germination rate. Potassium fulvicate is rich in a variety of nutrients. New roots can be seen in 3-7 days of use. At the same time, a large number of secondary roots are increased, which quickly improves the plant's ability to absorb nutrients and water, promotes cell division, and accelerates crop growth.
2. Improve fertilizer utilization efficiency. Potassium fulvicate provides the carbon and nitrogen sources needed for beneficial microbial activities in the soil, thereby promoting the proliferation of microorganisms. It can decompose phosphorus, decompose potassium and fix nitrogen, thereby greatly improving the utilization rate of nitrogen, phosphorus and potassium, generally increasing the utilization rate by more than 50%.
3. Improve the drought, cold and disease resistance of plants. Potassium fulvic acid can promote the formation of soil aggregate structure, enhance the soil's ability to retain fertilizer and water, and enhance the drought resistance of plants. Potassium fulvicate can enhance the photosynthesis of plants and increase the organic matter in plant cells, thus improving the cold resistance of crops. The plant's root system is developed, its ability to absorb nutrients and water is greatly enhanced, the plant is strong and has strong disease resistance.
4. Increase output and improve quality. Potassium fulvic acid is fully water-soluble, easy to absorb, and has strong permeability. Its effect is more than 5 times that of ordinary humic acid. The active substance of fulvic acid makes the absorption and utilization rate of nitrogen, phosphorus and potassium reach more than 50%, which greatly enhances the nutrition of plants themselves, increases yield and improves crop quality.
5. Improve soil and resist repeated cropping. Fulvic acid combines with calcium ions in the soil to form a stable aggregate structure, and the water, fertilizer, gas, and heat conditions of the soil can be adjusted. Beneficial bacteria multiply in large quantities in the soil, controlling harmful bacteria in the soil, thus improving crop resistance, and having an obvious repair function in hardening and soil salinization caused by long-term excessive fertilization.
The root is the most important organ of the plant, and the core part of the root is the root tip. It can sense the external environment and send out signals to guide the plant's nutrient absorption and hormone synthesis. Among the five well-known plant endogenous hormones, only auxin is mainly produced by the new leaves and new tissues in the upper part of the crop. The other four plant growth regulatory substances are all produced by the root tips. The oxygen consumption in this area is the highest in the entire plant, and there is an action potential signal similar to the human brain when exchanging information. Therefore, people call the root tip the "big brain of the plant."
Only deep roots can produce luxuriant leaves, and the quality of the root system determines the final yield and quality of the crop. However, after each new root goes through a 14-day growth cycle, its function will gradually decline until it dies. How to keep new roots growing and maintaining a healthy state is very important.
The division and differentiation of plant root cells require the combined action of auxin and mitogen. However, since the main production site of auxin is the new leaves and new tissues in the upper part of the crop, auxin needs to be continuously transported to the roots under the action of gravity and self-regulation. At this time, although the roots produce a large amount of mitogens, it is difficult to continuously generate new roots because there is not enough auxin to work together, especially under environmental stress conditions. At this time, soil humic acid can play a very good backup role.
The promoting effect of fulvic acid on plant growth has been confirmed by a large number of experimental studies. In general, the stimulating effect of fulvic acid on roots is greater than that on stems and leaves. Experiments have shown that adding a small amount of humic acid to the hydroponic medium can increase the root length of corn by 500%, and the dry weight and fresh weight of the roots are also significantly increased.
More experiments have shown that fulvic acid has auxin activity and promotes the synthesis of auxinase. Delicate studies have shown that fulvic acid has a greater promoting effect on cell elongation, and its effect on cell division is even more obvious. Therefore, when we use humic acid fertilizers, especially fulvic acid fertilizers, the root system of the crops can always be in a young and healthy state, thereby improving the crops' absorption and effect of water and nutrients.
What is the difference between mineral potassium fulvic acid and biochemical potassium fulvic acid?
Humic acid (mineral source) is a polymer of natural organic polymer compounds. It is a high molecular amorphous compound polymer formed by the decomposition of plant residues and microbial decomposition and transformation over tens of millions or even hundreds of millions of years, as well as a series of physical and chemical reactions on the earth.
The role of humic acid
1. Improve soil aggregate structure
2. Improve fertilizer utilization efficiency
3. Stimulate the reproduction of soil microorganisms
4. Promote crop growth
5. Chelate trace elements
6. Solubilize phosphorus and potassium
Humic acid includes black humic acid, brown humic acid, and fulvic acid. Many people confuse humic acid and fulvic acid. Simply put, humic acid is a type of organic mixture, and fulvic acid is one of the components with the smallest molecular weight. It is soluble in water, acid and alkali. . It is often proposed because it contains many functional groups (hydroxyl, carboxyl, methoxy, etc.), high activity, and good effects.
So what is potassium fulvic acid? What is the difference between mineral source and biochemistry?
Fulvic acid is divided into two categories based on its source: mineral fulvic acid (MFA) and biochemical fulvic acid (BFA).
From the source: Mineral fulvic acid is formed from the remains of animals and plants (lignite, weathered coal, peat) after tens of millions of years of transformation by soil microorganisms. Biochemical fulvic acid is produced by concentrating and spray-drying the waste water from molasses manufacturing alcohol or yeast production. Such fulvic acid absorbs moisture easily and has a sugary taste. In terms of ingredients: The main ingredients of biochemical potassium fulvic acid are polysaccharides, lignin, and protein, with very few functional groups. The mineral potassium fulvicate is rich in various functional groups such as hydroxyl groups, phenol groups, and carboxyl groups, and its utilization rate is very high.
From a functional perspective: Potassium fulvicate, a mineral source, can adjust soil pH due to its functional group, and is a natural chelating agent. Chelate with metal ions to reduce nutrient loss or solidification and promote direct absorption by plants. It can promote the insoluble aluminosilicate inorganic minerals (phosphorus and potassium) in the soil to form soluble nutrients, which can be directly absorbed and utilized by plants. Biochemical fulvic acid also has the effect of regulating acidity, improving soil, and stimulating root growth, but its sustainability is not strong and the effect is weak.
Humic acid is a good thing, and fulvic acid is the most active ingredient. Currently, the research and application of fulvic acid have matured, and there are real scientific verifications on many functions. This is no need for doubt.
