Products Description of KCL CAS#7447-40-7

Potassium chloride is an important fertilizer for plant growth. It has a fast fertilizer effect and can be absorbed by the soil. It is not easy to lose. Applying an appropriate amount of potassium fertilizer can make the stems of crops grow firm, prevent lodging, promote flowering and fruiting, and enhance the ability to resist drought, cold, diseases and pests. Therefore, it is of great significance to agricultural high yield. Germany used it as the main potassium fertilizer in 1861 and maintained its monopoly position in production for a long time.
