Fulvic acid is a colloidal organic matter, which can make the soil loose, adsorbed water, breathable and humid, moisture, drought, the soil has good water, gas and heat conditions, suitable for seed germination and seedling stage Grow.
Second, improve saline land
Fulvic acid molecular weight small, high activity, can adsorb the harmful cations in the soil, thereby reducing the concentration of salt in the soil, reducing the salt on the seeds and seedlings, improve the saline-alkali land
Third, drought and cold
1, fulvic acid spraying plant leaves, plants can close the stomata, reduce plant water transpiration
2, fulvic acid color is deep, is conducive to the absorption of solar energy; fulvic acid by the role of microorganisms decomposition will emit heat, can make the ground temperature increased, which play a role in cold resistance.
Fourth, anti-pests
Fulvic acid can increase the enzyme activity in plants and increase the body's resistance
Fifth, prevent heavy metal pollution
Fulvic acid is involved in the ion exchange reaction in the soil, adsorbing and immobilizing the heavy metal ions in the soil to prevent them from entering the biological circulation.
Sixth, improve fertilizer efficiency
1, nitrogen fixation: Nitrogen applied to the soil, it is easily volatile to the atmosphere or with the loss of water and soil into the river. Fulvic acid can adsorb nitrogen in the soil, reduce its volatilization and loss, and improve utilization
2, Phosphate: Phosphorus applied to the soil, easily fixed by the soil. Fulvic acid is able to release phosphorus from the soil through the chelation with phosphorus, which is used for plant absorption and improves the utilization of phosphorus
3, potassium: Potassium applied to the soil mostly in the form of potassium salts, can not be directly absorbed by crops. Fulvic acid can pass ion-exchange function, make insoluble potassium into soluble potassium, increase the available potassium in the soil and increase the utilization rate of potassium
4, micro-fertilizer: fulvic acid and insoluble trace elements chelation can occur to generate good solubility of crops can be absorbed humic acid trace element chelates, which is conducive to the root and foliar absorption of trace elements
Seven, to promote crop growth and development
1, fulvic acid can stimulate root growth, eventually leading to the ability of crops to absorb water and nutrients greatly enhanced
2, fulvic acid stimulating effect can plant vegetative vegetative growth on the ground. Performance in the plant height, stem diameter, leaf thickness and so on
3, fulvic acid on tillering, reduce the rate of air plutonium has a good effect, can increase grain thousand grain weight, increase food production
Eight, adjust the soil PH value
Fulvic acid more functional groups, both with acid, but also can be combined with alkali, according to crop needs to adjust the pH of the soil
