Properties
Potassium sulfate is colorless crystals, small hygroscopicity, not easy to agglomerate. With good physical properties, convenient for application, it is a good water-soluble potash fertilizer. Potassium sulfate is chemically neutral, physiological acid fertilizer. It is a chlorine-free, high quality and efficient potash fertilizer. In particular, it is indispensable important fertilizer for the crops of tobacco, grapes, sugar beets, tea, potatoes, flax and various fruit trees which should avoid chlorine. It is also raw materials of high-quality NPK fertilizer. The density is 2.66g/cm 3 . Its melting point is 1074℃, and boiling point is 1670°C. Solubility: 111 g/L at 20℃ water,insoluble in alcohol , carbon disulfide and acetone.
Benefits
Providing potassium to crops sensitive to chloride and salt
Contains a low salt index helping to avoid the plant taking up excess water
Mixes well with all other fertilizers

Warning
Long-term use of potassium sulphate should be used together with the manure, alkaline phosphate and lime with lower acidity, and in practice should be combined with the drainage bask in field measures to improve ventilation.
In calcareous soils, we should pay attention to use more farmyard manure.
Potassium sulphate should be applied with calcium-rich fertilizer
Potassium sulphate should not be touched with seeds and roots directly. It can be single use, but also can be used together with other single element fertilizer.
