Fulvic Acid Fertilizer Manufacturing Process
The manufacturing process of Fulvic Acid Fertilizer involves a specialized extraction method. Organic matter, often from peat or leonardite, is first harvested. This material undergoes a controlled extraction process using an alkaline solution, which isolates the fulvic acid. The extracted fulvic acid is then carefully filtered to remove impurities. Following filtration, the fulvic acid is concentrated to the desired level for use as a fertilizer. The final step involves drying the concentrated fulvic acid, converting it into a granular or powder form suitable for agricultural use. This process ensures that the fulvic acid retains its beneficial properties, making it an effective soil enhancer and plant growth stimulant.

100% Soluble Fulvic Acid
Humico fulvic acid, all forms or content grades are 100% water solubility, ensuring complete dissolution without clogging drip lines, no residue in tanks. So our fulvic acid can be applied through drip irrigation, foliar spray, fertigation, or hydroponics. And this make it can be mixed with NPK, trace elements, amino acids, humic acid or other complex to create your own customized formulas.
