Fulvic Acid

Funcion of fulvic acid in agriculture

The physical, chemical and biological properties of fulvic acid can improve the physicochemical properties of the soil and enhance the vigor of the soil to facilitate crop growth. It has an irreplaceable role in the repair of soil pollution.

In recent years, soil pollution, soil degradation, soil salinity, soil desertification, soil compaction and other problems have seriously eroded our land. Because of its remarkable effect on soil remediation, fulvic acid has once again become a hot spot for soil pollution prevention and environmental restoration since the national “10th Five-Year Plan” and “Eleventh Five-Year Plan” have carried out soil environmental remediation application research.

The fulvic acid is a kind of macromolecular organic weak acid polymer formed by a series of decomposition and transformation under the action of microorganisms and geophysical and chemical processes. It is widely found in nature, in soil, lakes, rivers, oceans, and lignite, weathered coal, and peat. 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.

The fulvic acid plays a leading role in the organic and inorganic complexes and soil structure, and can affect the material energy cycle of the soil, and has the ability of absorbing, transforming and releasing the soil nutrients and water. The eucalyptus acid has a very important influence on the soil’s self-regulation ability and stress resistance and all functions of the soil ecosystem. It can be said to be the pillar of the soil.
Fulvic acid – fertilizer utilization increased by 10%

The fulvic acid has the functions of quick-acting and slow-acting effect on fertilizer, and also increases the soil micro-aggregate structure and capillary porosity, reduces soil bulk density, improves soil fertility and water retention capacity, and controls urea release and decomposition rate.
The combination of fulvic acid and nitrogen fertilizer, phosphate fertilizer, potassium fertilizer and other trace elements can greatly improve the utilization rate of these fertilizers. The function of adsorption, chelation and so on of fulvic acid has a slow release effect on the effective nutrients in fertilizers and soil, and reduces leaching and loss.
 The fulvic acid can increase the utilization rate of fertilizer by an average of 10%. If the national agricultural land is used to use fulvic acid, according to the total fertilizer output of 7,432.43 million tons in 2012, the loss of chemical fertilizer can be reduced by 7,432,400 tons. Based on the urea production of 300.383 million tons, it can save 308,300 tons of urea, 4.41 million tons of standard coal and 2.5 billion kWh of electricity, and emit 12.17 million tons of carbon dioxide. It can also save phosphate and potash, as well as increase crop yield and quality, reduce environmental pollution, and improve agro-ecology.

On April 17, the Ministry of Environmental Protection and the Ministry of Land and Resources issued a national survey on soil pollution status, showing that the national soil over-standard rate was 16.1%; the number of inorganic pollutants exceeding the standard point accounted for 82.8% of all over-standard points, and the main pollutant was cadmium. Heavy metals such as mercury, arsenic and lead. As soon as the report came out, the soil pollution situation in China once again caused heated discussion.

The fulvic acid has unique physical, chemical and physiological properties such as adsorption, ion exchange, chelation, and redox. It is this law that fulvic acid adsorbs, desorbs, fixes, activates, improves bioavailability and reduces toxicity of various heavy metals and organic pollutants in soil. It is this law that fulvic acid provides soil remediation and improvement. Good conditions have the effect of improving bioavailability and reducing toxicity of various heavy metals and organic pollutants in the soil. After applying fulvic acid, it can improve the physical and chemical properties of the soil, enhance the vitality of the soil, and facilitate crop growth. The prevention and control of soil pollution has an extremely important role in the restoration of the environment.
