The characteristics of our humic acid series products
- Humic acid raw material(leonardite) comes from the mining with high content and low impurity in North West area. At present, the content of humic acid raw material(leonardite) in other provinces of China is worse than NW's leonardite.
- We only use high quality potassium hydroxide as raw material for neutralization reaction. We don't use other potassium sources, and don't use sodium hydroxide instead of potassium hydroxide for reaction.
- Do not add additional chemical auxiliary and bio fulvic acid raw materials, try to keep the natural characteristics of mineral source products.
- The main technical R&D personnel and workshop director have been working in humic acid industry for more than 20 years and have rich experience in all aspects.
- Product formula and production process after long-term verification, they're stable performance, scientific and reliable. Our production process involves winnowing, crushing, screening, neutralization, extraction, sedimentation, centrifugation, concentration, drying and so on.
- Strictly control the production reaction time and temperature of each stage in the production process, no cutting corners, ensure product quality.
- We are also one of the few humic acid manufacturers in China with a spray tower.
