Potassium chloride is an important fertilizer for plant growth, which has fast fertilizer effect and can be absorbed by the soil, and is not easy to lose. Applying proper amount of potassium fertilizer can make the crop stem grow solid, prevent lodging, promote flowering and fruiting, enhance drought resistance, cold resistance, disease resistance and insect pest resistance, so it has very important significance for agricultural high yield. 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 content and the reason, since potassium chloride is still the main varieties of potash in the world, accounts for about 90% of total sales of the global potash above, of which 50% directly applied, the rest are mainly used for manufacturing complex (mixed) fertilizer.

1)
Mainly used in the inorganic industry, it is the basic raw material for the manufacture of various potassium salts such as potassium sulfate and red strontium potassium.
2)
Nutrition enhancers; gelling agents; salt substitutes; yeast food; it is similar to table salt to use as flavour enhancers for the agricultural product, livestock forming product, condiment, can, convenient food and so on, And also to use as enhance the potassium to prepare athletes beverage.
3)The dye industry is used to produce reactive dyes and the like.
4)In agriculture, it is a potash. Its fertilizer efficiency is fast, it is directly applied to the farmland, which can raise the water in the lower layer of the soil and have the effect of drought resistance.
