Potassium Sulphate 7778-80-5
Category : Food and Feed additives
CAS NO : 7778-80-5 EC NO : 231-915-5 MF : K2SO4 MW : 174.24 Specification : Granular/Powder Packing : 25kg Bag,1000kg Bag Product description : 
Potassium sulphate is an important chlorine-free potassium fertilizer containing sulfur and potassium. K2O content is 50%-52%, and the S content is about 17%-18%. Agricultural potassium sulfate is mostly pale yellow. Potassium sulfate is a water-soluble potassium fertilizer because of its low moisture absorption, non-caking, good physical properties and convenient application. Potassium sulfate is especially suitable for cash crops that are resistant to chlorine and like potassium, such as tobacco, grapes, beet, tea, potatoes, flax and various fruit trees. It is also the main raw material for making chlorine-free nitrogen, phosphorus and potassium ternary compound fertilizer. Potassium sulfate is a chemical neutral and physiological acidic fertilizer, which is suitable for a variety of soils (excluding flooded soils) and crops.
Potassium sulphate is a chemical neutral and physical acid fertilizer, which is widely used in all kinds of soil and crops, especially for avoiding chloride. Potassium sulphate replaces potassium chloride and becomes a good potassium fertilizer. Potassium sulfate is a very good water-soluble potassium fertilizer because of its low hygroscopicity, low caking, good physical properties and convenient application. Potassium sulphate is especially suitable for cash crops that are not chlorpyrifos, such as tobacco, grape, beet, tea, potato, flax and various fruit trees.
1. It can be used as base fertilizer. When potassium sulfate is used as base fertilizer in the dry field, it is necessary to deeply cover the soil to reduce the crystal fixation of potassium, facilitate the absorption of crop roots and improve the utilization rate.
2. As topdressing. As the mobility of potassium in the soil is small, it should be applied to the soil layer with dense root system in order to promote the absorption.
3. It can be used as seed fertilizer and root top dressing. The amount of seed fertilizer used per mu is 1.5-2.5kg, which can also be made into 2% - 3% solution and used as external topdressing.
