Mineral Potassium-K Fulvate (fulvic acid potassium salt) for Organic NPK fertilizer, is one of the major components of humic substances.
It is obtained by alkaline extraction of lignite or brown coal or leonardite and is used commercially as a soil conditioner.
Chemically, potassium-K fulvate (fulvic acid potassium salt) is a super-molecular heterogeneous aromatic hydroxy carboxylic acid composed by various functional groups, taking on effects of absorption, complexation, chelation, flocculation, which dissolves loads of hydrophobic matters.
Function & Benefits:
Enhancing nutrient uptake by combining nutrients and humic aid as well as keep a well-balanced nutrition.
Improving structure of soil, increase buffering powder of soil, optimize N. P. K absorption by plants.
Increasing capacities of water holding and cation exchange, enhancing soil ability of anti-hard water
Reducing nitrate leaking into groundwater and protect the underground water
Enhancing the resilience of crops, such as cold, drought, pest, disease and toppling resistance
Stabilizing nitrogen and improve nitrogen efficiency (as an additive with urea)
Promoting healthier, stronger plants and beautify appearance
Detoxifying pesticide residues on the edible seed or fruits
