Potassium Humate Black Flake Powder

Potassium humate is a kind of heterogeneous aromatic hydroxyl carboxylate with the appearance of black particles or powder solid. It is the product extracted by the reaction of KOH liquid after fine preparation of lignite. It is soluble in water, alkaline and contains carboxyl, phenolic hydroxyl and other active groups.

The humic acid functional group in potassium humate can absorb and store potassium ions, prevent water loss in sandy soils and leaching soils, and prevent the fixation of potassium in cohesive soils. In addition, some parts of potassium humate are low molecular humic acid such as fulvic acid, which has a dissolution effect on minerals such as potassium-containing silicate and potassium feldspar, which can slowly decompose to increase the release of potassium and increase the content of available potassium. Compared with the ordinary potassium fertilizer utilization rate increased by 87%-95%, so that the fertilizer efficiency increase.
