This kind of Potassium humate 90% is a high-efficiency organic potassium fertilizer, in which humic acid is a biologically active preparation and can increase soil available potassium content, reduce potassium loss and fixation, as well as increase potassium absorption and utilization of crops. Its appearance is black granules or powdery solids. It is a product obtained by finely selecting lignite and then extracting with KOH liquid. In addition, it is soluble in water, and contains active groups such as carboxyl groups and phenolic hydroxyl groups. What’s more, the Potassium humate 90% can be made into a highly efficient multi-functional compound fertilizer when mixed with urea, phosphate fertilizer, potassium fertilizer, trace elements, etc. Besides, it can also be used as a treatment agent for petroleum drilling fluids, mainly to prevent collapse of the well wall.
