The dominant use of potassium sulfate is as a fertilizer. K2SO4 does not contain chloride, which can be harmful to some crops. Potassium sulfate is preferred for these crops, which include tobacco and some fruits and vegetables.

Potassium sulphate is an important chlorine-free potassium fertilizer containing sulfur and potassium. K2O content is 50%-52%, and the S content is about 17%-18%. Agricultural potassium sulfate is mostly pale yellow. Potassium sulfate is a water-soluble potassium fertilizer because of its low moisture absorption, non-caking, good physical properties and convenient application. Potassium sulfate is especially suitable for cash crops that are resistant to chlorine and like potassium, such as tobacco, grapes, beet, tea, potatoes, flax and various fruit trees. It is also the main raw material for making chlorine-free nitrogen, phosphorus and potassium ternary compound fertilizer. Potassium sulfate is a chemical neutral and physiological acidic fertilizer, which is suitable for a variety of soils (excluding flooded soils) and crops. The specific use methods are as follows: 1. It can be used as base fertilizer. When potassium sulfate is used as base fertilizer in the dry field, it is necessary to deeply cover the soil to reduce the crystal fixation of potassium, facilitate the absorption of crop roots and improve the utilization rate. 2. As topdressing. As the mobility of potassium in the soil is small, it should be applied to the soil layer with dense root system in order to promote the absorption. 3. It can be used as seed fertilizer and root top dressing. The amount of seed fertilizer used per mu is 1.5-2.5kg, which can also be made into 2% - 3% solution and used as external topdressing.
Potassium sulfate, often referred to as sulfate of potassium or SOP, is a chemical compound with the formula K2SO4. It is a colorless or white crystalline solid that is soluble in water. Potassium sulfate is commonly used in various applications, including agriculture, industry, and laboratory settings. Here are some key points about potassium sulfate: Chemical Formula: K2SO4 Solubility: Potassium sulfate is highly soluble in water, and its aqueous solution is neutral. Sources: Potassium sulfate can be obtained from natural sources, such as minerals like arcanite and aphthitalite. It can also be produced through chemical processes, including the reaction between potassium chloride and sulfuric acid. Agricultural Use: Potassium sulfate is a popular fertilizer in agriculture, providing essential potassium and sulfur nutrients to plants. It is often favored in situations where the addition of chloride is undesirable, as opposed to potassium chloride. Industrial Applications: Potassium sulfate is used in various industrial processes, including the production of glass and textiles. It is employed in certain types of glazes for ceramics. Laboratory Use: In laboratory settings, potassium sulfate can be used as a drying agent due to its hygroscopic nature. Compatibility with Plants: Potassium is an essential nutrient for plant growth and development. It plays a crucial role in various physiological processes, including enzyme activation, photosynthesis, and osmoregulation. Sulfur is also important for plant nutrition and is involved in the synthesis of amino acids and proteins.
