Different extraction processes lead to different biological activities. This product is produced using a three-step extraction method: caustic alkali extraction, nitric acid oxidation, and grafting modification. The fulvic acid extracted from lignite is higher in content and stronger in biological activity. The product utilizes nitric acid oxidation activation technology to increase fulvic acid content, while simultaneously breaking down large molecular chains into smaller ones, increasing the number of oxygen-containing active functional groups, enhancing chelation ability, and improving acid regulation and salt reduction capabilities. Grafting modification technology is used to further increase hydrophilic groups, improving resistance to acids and hard water.
