potassium sulfate price npk 0 0 52 sop fertilizer 50kg for sale

It is a basic raw material for producing various potassium salts such as potassium carbonate and potassium persulfate. The glass industry is used as a sinking agent. The dye industry is used as an intermediate. The perfume industry is used as an auxiliary agent. The pharmaceutical industry is also used as a laxative to treat soluble bismuth salt poisoning. Potassium sulphate is a commonly used potassium fertilizer in agriculture. The potassium oxide content is 50%, which is commonly known as "Baijiali" in Taiwan. In addition, potassium sulfate is also used industrially in glass, dyes, perfumes, medicines, and the like.

Potassium sulphate is a colorless crystal, has low hygroscopicity, is not easy to agglomerate, has good physical properties, and is convenient to apply, and is a good water-soluble potassium fertilizer. Potassium sulphate is also a chemically neutral, physiologically acidic fertilizer. Potassium sulphate is a kind of chlorine-free, high-quality and high-efficiency potash, especially in the cultivation of chlorine-sensitive crops such as tobacco, grape, sugar beet, tea tree, potato, flax and various fruit trees. It is also an indispensable important fertilizer; it is also high quality. The main raw material of nitrogen, phosphorus and potassium ternary compound fertilizer.

Potassium sulphate type compound fertilizer is produced by low temperature conversion, chemical synthesis and spray granulation process of potassium chloride. It has good stability and contains S, Ca, in addition to the three major nutrients such as N, P and K which are necessary for plants. , trace elements such as Mg, Zn, Fe, Cu, etc. This fertilizer is suitable for a variety of cash crops, especially for chlorine-sensitive crops. The main components of the potassium sulfate type compound fertilizer are MAP (monoammonium phosphate) DAP (diammonium phosphate), ammonium sulfate (mainly obtained by low-temperature conversion of surplus sulfuric acid and gas ammonia). Potassium sulphate, urea and the like also have some small amounts of impurities such as calcium sulphate, iron, aluminum, magnesium and other salts of phosphate and a small amount of unreacted potassium chloride.

Precautions for use

First, in acidic soils, excess sulfate will increase the acidity of the soil and even increase the toxicity of active aluminum and iron in the soil. Under flooding conditions, too much sulfate will be reduced to form hydrogen sulfide, causing the roots to become black. Therefore, the long-term application of potassium sulfate should be combined with farmyard manure, alkaline phosphate fertilizer and lime to reduce the acidity. In practice, it should also be combined with drainage and drying measures to improve ventilation.

Second, in calcareous soils, sulfate and calcium ions in the soil produce calcium sulfate (gypsum) that is not easily soluble. Too much calcium sulphate will cause soil compaction. At this time, we should pay attention to the application of farmyard manure.

Third, the key use in the avoidance of chlorine crops, such as tobacco, tea trees, grapes, sugar cane, sugar beets, watermelons, potatoes, etc., increased potassium but not only increased yield, but also improved quality. The price of potassium sulphate is higher than that of potassium chloride, and there are few sources of supply. The focus should be on economic crops that are sensitive to chlorine and sulphur and potassium. The benefits will be better.

Fourth, the fertilizer is a physiologically acidic salt that is applied to alkaline soils to reduce soil pH.
