How to Choose High Quality Humic Acid

 

The current humic acid market is chaotic, many small factories to shoddy with coal gangue, carbon powder as humic acid, or add some dyes, so that clients can hardly distinguish between true and false. How can we select high quality humic acid products? Here are some simple ways as follow,

 

- Appearance

Most of the high activity humic acid raw materials are black brown or brown. The higher activity and the lower water content, the more obvious brown. In addition, it is important to note that humic acid powder with few impurities, high content and low water content is not easy to granulate directly with water. Binder or bentonite can be added for granulation.

 

- Solving Liquid

Good quality humate products dissolve in water and the unsaturated solution appears tawny or dark brown color. After dipping with the hand, the color is also brown or dark brown on the hand and when washing. The flocculation phenomenon cannot directly judge the quality of products, because mineral source humic acid products are characterized by complex metal divalent ions. If there is no flocculation at all, it may be a biochemical source or adding some additives during the production process.

 

- Hygroscopicity

Highly active humic acid has good hygroscopicity, but it will not agglomerate easily. Therefore, we try to use inner packaging to prevent the return of moisture when the goods are packed.
