Potassium humate (K-humate) is one of the major components of humic substances. Potassium humate is obtained by alkaline extraction of lignite or brown coal or leonardite and is used commercially as a soil conditioner.
Chemically, it is a super-molecular heterogeneous aromatic hydroxy carboxylic acid composed by various functional groups, taking on effects of sorption, complexation, chelation, flocculation, which dissolves loads of hydrophobic matters.
- Enhancing nutrient uptake by combining nutrients and humic aid as well as keep a well-balanced nutrition.
- Improving the structure of soil, increasing the buffering powder of soil, optimize N. P. K absorption by plants.
- Neutralizing both acid and alkaline soils, regulating the PH value of soils, with the prominent effect in alkaline and acidic soil
- Reducing nitrate leaking into the groundwater and protect the underground water
- Enhancing the resilience of crops, such as cold, drought, pest, disease and toppling resistance
- Stabilizing nitrogen and improving nitrogen efficiency (as an additive with urea)
- Promoting healthier, stronger plants and beautifying appearance
