Potassium sulfate is a chlorine-free high-quality potash, suitable for a variety of cash crops, especially for bogey crops such as tobacco, fruit, sugar beet, sweet potato and so on. This fertilizer, mainly to improve the crop yield, and significantly improve its quality.
Potassium is theoretically 54%, generally 50%; is a chemical neutral, physiological acid fertilizer, has a good water-soluble, but long-term use, Potassium Sulphate will increase soil acidification, suitable for grape coloring to fruit ripening period, to promote fruit Powder coloring, increase fruit sweetness.
Application of potassium sulfate in different soil reactions and should pay attention to matters:
(1) in the acidic soil, the excess sulfate will increase the acidity of the soil, Potassium Sulphate and even exacerbate the soil active aluminum, iron poisoning the crop. In the flooding conditions, too much sulfate will be reduced to generate hydrogen sulfide, so that the root damage black. Therefore, Potassium Sulphate 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 bogey chlorine crops, such as tobacco, tea, grapes, sugar cane, beets, 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 sulfur potassium on the economic crops, Potassium Sulphate the benefits will be better.
(4) Potassium sulfate should not be mixed with calcium-rich fertilizer.
It is said that a lot of fruit area of manganese poisoning is caused by soil acidification, and the direct cause of soil acidification is the use of potassium sulfate year round. So, fertilizer, Potassium Sulphate nothing to change with the use, do not have been used, you have to eat something will cause malnutrition, let alone the land.
Potassium sulfate is a compound formed by the combination of sulfate ions and potassium ions.
The solid is a colorless or white hexagonal or orthorhombic crystal or granular powder.
Soluble in water, insoluble in alcohol, acetone and carbon disulfide. With bitter taste.
Potassium sulfate is commonly used in agriculture potash, potassium content of about 50%.
In addition, potassium sulfate in the industry is also used for glass, dyes, spices, medicine and so on.
Is the manufacture of various potassium salts such as potassium carbonate, potassium sulfate and other basic raw materials.
The glass industry is used as a cleaning agent, a clarifier, a dyestuff industry for intermediates, a spice industry as a builder, and a pharmaceutical industry as a laxative. Potassium sulfate is commonly used in agriculture, chemical fertilizers, potash, potassium content of about 50%, Potassium Sulphate the food industry as additives.
Potassium sulfate role and use:
Is the manufacture of various potassium salts such as potassium carbonate, potassium sulfate and other basic raw materials. The glass industry is used as a cleaning agent. The dye industry is used as an intermediate. Spice industry as auxiliaries and so on. The pharmaceutical industry is also used as a laxative, Potassium Sulphate the treatment of soluble barium salt poisoning. Potassium sulfate in agriculture is commonly used potash, potassium oxide content of 50%, commonly known as "white plus" in Taiwan. In addition, potassium sulfate in the industry is also used for glass, dyes, spices, medicine and so on.
