Potassium Humate is a natural organic macromolecule extracted from high-quality weathered coal, lignite, and peat via advanced alkaline extraction and purification. It presents as black/brown amorphous powder, flakes, or granules, with good water solubility (≥95%) and chemical stability, suitable for pH 4.0-10.0 and resistant to 120℃ without decomposition. Non-toxic, residue-free, and highly compatible, it serves as an eco-friendly agent in agriculture, animal husbandry, aquaculture, and environmental protection.
| Test Item | Standard Requirement | Test Result | Test Method |
|---|---|---|---|
| Humic Acid Content (Dry Basis) | 40-65% | 40-65% | GB/T 11957-2001 |
| Moisture Content | ≤8.0% | 6.3% | GB/T 8576-2010 |
| pH Value (1% Aqueous Solution) | 7.8-9.8 | 8.6 | GB/T 9724-2007 |
| Heavy Metal (Cd) Content | ≤5 mg/kg | 2.3 mg/kg | GB/T 23349-2020 |
Purified to remove heavy metals and harmful microbes, with humic acid content up to 70%-95%.
Active groups (carboxyl, hydroxyl) boost nutrient absorption by 30%-50% via chelating trace elements (Fe, Zn, Mn).
Fast-dissolving, no caking, mixable with fertilizers, pesticides, or feed additives.
Improves soil structure (loosens compacted soil, retains water/fertilizer), activates beneficial microbes, and enhances crop stress resistance (drought/cold/disease). Applied via soil (5-10kg/mu), foliar spray (0.1%-0.3% solution), or drip irrigation (0.05%-0.1% solution).
1. Promote metabolism and accelerate growth.
2. Improve meat quality and increase output of eggs/milk.
3. Enhances animal hair shine.
4. Increase disease resistance and growth capability.
1. Supplements carbon source in water.
2. Purifies water quality through strong adsorption.
3. Provides physical shading to prevent moss growth by blocking specific sunlight penetration.
Regulates plant hormones to prevent overgrowth and optimize nutrient uptake. In oil drilling, it serves as a high-performance mud additive, stabilizing fluids under harsh conditions and reducing friction.
