Potassium sulfate is a colorless or white hexagonal or orthorhombic crystal or granular powder. The relative density of 2.662 conversion point 588 ℃, the melting point of 1069 ℃, the boiling point of 1689 ℃. Soluble in water (12 ° C / 100ML water at 25 ° C, 24.1G / 100ML water at 100 ° C), insoluble in alcohol, acetone and carbon disulfide. With bitter taste.
Potassium sulfate Use:
The military industry is used as a smoke suppressor for shells. Used as a chemical fertilizer in agriculture. Is the raw Potassium Sulphate material for making potash. The dye industry is used as an intermediate. The glass industry is used as a cleaning agent. Medicine for laxatives. Spices are used as additives in the industry. The food industry is used as a general additive. Also used for serum protein biochemical tests.
Potassium sulfate storage and transportation:
Store in a dry, dry room. Packaging sealed, to avoid moisture, transport to prevent the loss of rain to melt.
What should I pay attention to when using potassium sulfate?
Foliar fertilizer Potassium sulfate Potassium on the theoretical 54%, generally 50%; is a chemical neutral, physiological Potassium Sulphate acid fertilizer, has a good water-soluble, but long-term use, will increase the soil acidification, suitable for grape coloring later to fruit ripening Period, to promote the fruit powder coloring, increase the fruit sweetness. Here to give you under the use of potassium sulfate should pay attention to what?
Precautions for using potassium sulfate:
(1) in the acidic soil, the excess sulfate will increase the acidity of the soil, and even increase the soil active aluminum, iron poisoning crops. In the flooding conditions, too much sulfate will be reduced to generate hydrogen sulfide, so that the root damage black. Therefore, the long-term use of potassium sulfate and farm manure, alkaline phosphate and lime with the reduction of acidity, in practice should also be combined with drainage measures to improve ventilation.
(2) in the calcareous soil, sulfate and soil calcium ions in the soil is not easy to dissolve calcium sulfate.
(3) focus on the use of avoid chlorine crops, such as tobacco, tea, grapes, sugar cane, beet, watermelon, potato and other potash increase not only yield, but also improve the quality. Potassium sulfate price is more expensive than potassium chloride, less supply, should focus on the use of chlorine sensitive and hi hi potassium on the economic crops, the benefits will be better.
(4) potassium sulfate should not be mixed with calcium-rich fertilizer application.
It is said that a lot of fruit area of manganese poisoning is caused by soil acidification, and the direct cause of soil Potassium Sulphate acidification is the use of potassium sulfate year round. So, fertilizer, nothing to change with the use, do not have been used, you have been eating something that will cause malnutrition, let alone the land.
