Fertilizer granlular Potassium Sulphate
Properties and applications:
Potassium Sulphate is white granular, it is insoluble in alcohol, acetone and carbon dioxide; It is chemical fertilizer, mainly applied in agriculture and other fields.
1)Used for drugs (such as laxatives), fertilizer(about 50% potassium, potassium is a quick, can be used as basic fertilizer, seed fertilizer and top dressing). Also used for making alum, glass, and potassium carbonate
(2) can be used as the raw material to produce multiple-element compound fertilizer, or as potassium fertilizer to fertilize field, especially applicable to chloride-resistant industrial crops such as tobacco, grape, cotton, beet
Potassium sulfate is a colorless crystal, moisture absorption, easy caking, good physical properties, easy application, is a good water-soluble potash. Potassium sulfate is chemically neutral, physiological acidic fertilizer. Reactions in different soils and should pay attention: First, in acid soil, the excess of acid sulfate soils will increase, and even increased activity of soil aluminum, iron toxicity on crops. In flooding conditions, the excessive reduction of sulfate would be generated hydrogen sulfide, so that victims of black roots. Therefore, the long-term use of potassium sulfate with the manure, alkaline phosphate and lime with lower acidity, in practice, should be combined with drainage Shaitian measures to improve ventilation. Second, in calcareous soil, and soil calcium sulfate ions generated insoluble calcium sulfate (gypsum). Calcium sulfate will cause excessive soil compaction, increased attention should be paid at this time applied manure. Third, avoid using chlorine key crops such as tobacco, tea, grapes, sugar cane, beet, watermelon, potato, etc.
