Potassium Fulvate Powder/Flake/Crystal is a kind of high polymer heterogeneous aromatic potassium salt contains hydroxyl, carboxyl and other active groups. It contains abundant high molecular humic acid and low molecular fulvic acid which extracts from natural mineral source raw materials. Humic acid has strong adsorption capacity to slow release and increase the efficiency of chemical fertilizer. Fulvic acid has strong biological stimulation for crop growth and its small molecule structure let the plant absorb easier and better. The organic combination of both has better effect for the crop and has good solubility with NPK water-soluble fertilizer.
