Agricultural Grade Potassium Sulfate

Potassium sulfate is an inorganic salt with the chemical formula K₂SO₄. Generally, the K content is 50%~52%, and the S content is about 18%. Pure potassium sulfate is a colorless crystal, and agricultural potassium sulfate is mostly light yellow in appearance.

Role and use

It is the basic raw material for manufacturing various potassium salts such as potassium carbonate and potassium persulfate. Used as a Shen Qing agent in the glass industry. Used as an intermediate in the dye industry. Used as auxiliary agent in perfume industry. The pharmaceutical industry is also used as a laxative, the treatment of soluble barium salt poisoning, etc. Potassium sulfate is a commonly used potassium fertilizer in agriculture, with a potassium oxide content of 50%.

Agricultural applications

Potassium sulfate is a colorless crystal with low hygroscopicity, not easy to agglomerate, good physical properties and convenient application. It is a good water-soluble potassium fertilizer. Potassium sulfate is also a chemically neutral, physiologically acidic fertilizer. Potassium sulfate is a kind of chlorine-free, high-quality and high-efficiency potassium fertilizer, especially in the planting of chlorine-sensitive crops such as tobacco, grapes, sugar beets, tea trees, potatoes, flax and various fruit trees. It is an indispensable important fertilizer; it is also a high-quality fertilizer. The main raw material of nitrogen, phosphorus and potassium ternary compound fertilizer.

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

FAQ:

Q1: What kind of fertilizer is potassium sulfate? Is it compound fertilizer?

Answer: Potassium sulfate K2SO4

Chemical fertilizers are mainly nitrogen, phosphorus, and potassium fertilizers, and compound fertilizers are fertilizers containing two or more

K2SO4 does not contain N and P, so it is not a compound fertilizer but a potash fertilizer.

Q2: What are the advantages of potassium sulfate?

Answer: Potassium sulfate can be made from natural potassium sulfate ore, or it can be made by decomposing potassium chloride with sulfuric acid. The molecular formula of potassium sulfate is shuK2SO4, containing K2O 33% to 50% or more, white or light yellow crystals or particles, and red potassium sulfate. Potassium sulfate has good physical properties, low hygroscopicity, not easy to agglomerate, easy to apply, easily soluble in water, and is a chemically neutral, physiologically acidic quick-acting fertilizer. .

Q3: What is your delivery time?

Answer: Usually 30 days after receiving the advance payment. Urgently need to discuss with us to find a way out!

Q4: What is the shelf life of these goods?

Answer: The shelf life of our products is 2 years, which is based on dry and ventilated conditions.

Q5: How to distinguish potassium sulfate?

Answer: How to distinguish potassium sulfate

1.  easily soluble in water, odorless;

2. pH test, the solution is neutral;

3. In the barium chloride test, there is a large amount of white precipitate, and it is insoluble in acid (qualitative detection of sulfate);

4. The flame color reaction test is a blue-violet flame (qualitative detection of potassium ions).
