The Eight Effects of Fulvic Acid on Crops
First: water retention.
Fulvic acid is a colloidal organic material, it can make the soil loose, adsorption water, breathable and humidification, moisture storage, protection against drought, which make the soil has good condition of water, air and heat, that is suitable for seed germination and seedling grow.
Second: improved saline-alkali land.
Fulvic acid has a small molecular weight and high activity, which can adsorb harmful cations in the soil, thereby reducing the concentration of salt in the soil, reducing the harm of the salt to seeds and seedlings, and improving the saline-alkali soil.
Third: drought resistance and cold resistance.
1.Spray the fulvic acid to the plant leaves, which can be used to close the stomata and reduce the moisture transpiration of plants.
2. The color of fulvic acid is deep, which is conducive to the absorption of solar energy; fulvic acid will release heat when the microbes break down, can improve the ground temperature, which play the anti-cold role.
Fourth: resistant to pests and diseases.
Fulvic acid can increase the activity of enzyme in plants and increase the resistance of plant organism.
Fifth: anti-heavy metal pollution.
Fulvic acid is involved in the exchange reaction of ions in the soil, trapping heavy metal ions in the soil to prevent them from entering the biological cycle.
Sixth: improve the fertilizer efficiency.
1.Nitrogen fixation: nitrogen is applied to the soil, easily volatilizing into the atmosphere or draining into the river. Fulvic acid can adsorb nitrogen in the soil, reduce its volatilization and loss, and improve the utilization rate
2.Dephosphorization: Phosphorus is applied to the soil and is easily fixed by soil. Fulvic acid can be liberated from soil by the chelation of phosphorus elements, which can be used for plant absorption and increase the utilization rate of phosphorus.
3.Activated Potassium: Potassium applied to the soil mostly in the form of potassium salt and can not be absorbed directly by crops. Fulvic acid can be converted into soluble potassium by ion exchange, increase the available potassium in the soil and improving the utilization rata of potassium.
4.Micronutrient fertilizer: fulvic acid and insoluble trace elements can chelate reaction, generate good solubility can be absorbed by crops of humic acid trace element chelate, which is advantageous to the root and leaf to absorption the trace elements.
Seventh: to promote the growth and development of crops.
1.Fulvic acid can stimulate the growth of roots, and ultimately lead to the ability of crops to absorb water and nutrients greatly enhanced.
2.The stimulating effect of fulvic acid can stimulate the growth of the vegetative part of the plant. The performance is plant height, stem diameter, thick leaves, etc.
3.The effect of fulvic acid on tillering and reduction of air-rate is good, which can increase grain weight and production.
Eighth: adjustment of soil PH.
Fulvic acid has more functional groups, and can be combined with both acid and alkali, which can adjust the acidity of soil according to the needs of crops.
