Usage
It is the basic raw material for producing various potassium salts such as potassium carbonate and potassium per sulfate. The glass industry is used as a detergents.The dye industry is used as an intermediate.Perfume industry used as additives, etc.The pharmaceutical industry also used as laxative agent, treatment of soluble barium salt poisoning.Potassium sulfate is commonly used in agriculture, potassium oxide content of 50 percent, commonly known in Taiwan as "white Gary."In addition, potassium sulfate is also used in glass, dyes, spices, medicine and so on.

(1) can be used as base fertilizer.When using potassium sulfate as base fertilizer in dry land, it is necessary to apply deep covering soil to reduce the crystal fixation of potassium, and use crop root system to absorb and improve the utilization rate.
(2) for topdressing.Due to the low mobility of potassium in the soil, banded or acupoint application should be concentrated in the soil layer with dense root system to promote absorption.Sandy soil often lack of potassium, should be used as topdressing to avoid leaching.
(3) can be used as seed fertilizer and topdressing.It can also be prepared into 2% ~ 3% solution for topdressing.
