Eight Functions of Mineral Fulvic Acid
The mineral potassium fulvate is a kind of black powdery substance dissolved in water. It is a plant growth regulator, which can promote plant growth and play an important role in drought resistance. It can improve plant stress resistance, yield and quality.
Principle 1: Potassium fulvic acid is a colloidal organic substance, which can make the soil loose, absorb large amount of water, ventilate and moisten, nourish soil moisture, prevent drought, make the soil have good water, air and heat conditions, and is suitable for seed germination and seedling growth.
Principle 2: The molecular weight of potassium fulvate is small and its activity is high. It can absorb harmful cations in soil, so as to reduce the concentration of salt in soil, reduce the harm of salt to seeds and seedlings, and improve saline alkali soil.
Principle 3: Drought resistance and cold resistance
1) Spraying mineral potassium fulvic acid on plant leaves can close the stomata and reduce water transpiration.
2) Mineral potassium fulvic acid will release heat when it is decomposed by microorganisms, which can improve the ground temperature and play the role of cold resistance.
Principle 4: Potassium fulvate can increase the activity of enzymes and the resistance of plants.
Principle 5: In order to prevent heavy metal pollution, potassium fulvate participates in the ion exchange reaction in the soil, adsorbs and immobilizes heavy metal ions in the soil, and prevents them from entering the biological cycle.
Principle 6: Improve fertilizer efficiency
1)Nitrogen fixation: when nitrogen is applied to the soil, it is easy to volatilize into the atmosphere or into rivers with soil erosion. Mineral potassium fulvic acid can adsorb nitrogen in soil, reduce its volatilization and loss, and improve the utilization rate.
2)Solubilization of phosphorus: when phosphorus is applied to the soil, it is easy to be fixed by the soil. Mineral potassium fulvate can liberate phosphorus from soil by chelating with phosphorus, which can be used for plant absorption and improve the utilization rate of phosphorus.
3)Activated potassium: most of the potassium applied to the soil exists in the form of potassium salt, which cannot be directly absorbed by crops. Mineral potassium fulvic acid can transform insoluble potassium into soluble potassium through ion exchange function, increase the available potassium in soil and improve the utilization rate of potassium.
4)Micro fertilizer: mineral potassium fulvic acid can chelate with insoluble trace elements to form humic acid trace element chelate with good solubility and can be absorbed by crops, which is conducive to the absorption of trace elements by roots and leaves.
Principle 7: Promote the growth and development of crops
1) Mineral potassium fulvate can stimulate the growth of root system, and ultimately enhance the ability of crops to absorb water and nutrients
2)The stimulating effect of mineral potassium fulvate can make the vegetative body of above ground part of plant grow vigorously. Plant height, stem diameter, leaf thickness, etc..
3)The mineral potassium fulvic acid has good effect on tillering and reducing the rate of empty chaff, which can increase 1000 grain weight and increase grain yield.
Principle 8: To adjust the pH value of soil, the mineral source fulvic acid potassium has many functional groups, which can combine with both acid and alkali, and can adjust the pH value of soil according to the needs of crops.
