 3.Other: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. Adding not only the increase in production of potassium sulfate, but also to improve quality. Potassium chloride prices expensive, less supply, should focus on the chlorine used in the hi-sensitive potassium and sulfur hi crops, the benefits will be better. Fourth, the potassium fertilizer should be mixed with calcium-rich application. General Mushi ten kilograms.
