Germany adopted it as a major potash fertilizer in 1861 and maintained its monopoly on Chemicalbook production for a long time. Potassium chloride is also China's major agricultural potassium fertilizer varieties, because of the rich mineral resources, the production method is simple, low cost, high k content
