Difference between Mineral Source Fulvic Acid and Bio Fulvic Acid
Mineral source fulvic acid is a kind of small molecular organic compound extracted from lignite, which is the most valuable part of humic acid for agricultural production and soil remediation. And bio fulvic acid is currently made from sucrose and monosodium glutamate papermaking scraps.
The dosage of mineral source fulvic acid is only 1/10 of bio fulvic acid. Taking application as an example, the amount of mineral source FA is 3 - 7 kg per ha, while the amount of bio FA application is 70 - 150 kg or more.
In term of ingredients, the main source of mineral fulvic acid is extracted from lignite formed by millions of years. It contains abundant hydroxyl, carboxyl, phenolic hydroxyl and methoxyl functional groups with high activity. The main components of bio fulvic acid are polysaccharide, lignin, and protein with few functional groups. Therefore, compared with bio fulvic acid, mineral source fulvic acid is much better in improving the quality and efficiency of crops and soil remediation. Mineral source fulvic acid is composed of 60-70 mineral elements, which is exactly what the soil needs to supplement. Mineral Fulvic acid is the essence formed by the remains of plants and animals, and the content of organic matter is much higher than bio fulvic acid.
The structure of fulvic acid is unique and suitable for add it into fertilizer. The mineral source fulvic acid has a large exchange capacity with cavitation structure, which can form soil aggregate structure and improve fertilizer utilization rate without absorbing moisture. The biggest deficiency of bio fulvic acid is easy to absorb moisture. When it is used as functional fertilizer and compound fertilizer additive, adding more than 25 kg in 1 metric ton fertilizer will lead to the serious moisture absorption of fertilizers and agglomerate, or even become muddy. This is determined by its innate structure, and there is no effective solution in the industry at present.
