High efficiency organic potassium fertilizer: potassium humate is a kind of aromatic hydroxyl carboxylate with high molecular heterogeneity. Its appearance is black particles or powdery solid. It is the product extracted by KOH liquid reaction after fine separation of lignite. It is soluble in water, alkaline and contains carboxyl, phenolic hydroxyl and other active groups. Potassium humate is a high-efficiency organic potassium fertilizer, because the humic acid in it is a bioactive agent, which can improve the content of soil available potassium, reduce the loss and fixation of potassium, increase the absorption and utilization rate of potassium by crops, and also has the functions of improving soil, promoting crop growth, improving crop stress resistance, improving crop quality and protecting agricultural ecological environment; After mixing with urea, phosphate fertilizer, potassium fertilizer and trace elements, it can be made into high-efficiency multifunctional compound fertilizer; In addition, potassium humate can also be used as a treatment agent for oil drilling fluid, mainly to prevent wellbore collapse.
Function: the humic acid functional group in potassium humate can absorb and store potassium ions, prevent them from losing with water in sandy soil and leaching soil, and prevent the fixation of potassium by cohesive soil. In addition, some parts of potassium humate are low molecular humic acids such as fulvic acid, which can dissolve minerals such as potassium silicate and potassium feldspar. It can decompose slowly, increase the release of potassium and increase the content of available potassium. The utilization rate of potassium fertilizer is 87% - 95% higher than that of ordinary potassium fertilizer, which increases fertilizer efficiency, crop yield and quality.
