    Product Description

    Name: Potassium sulfate (US) or potassium sulphate (UK), also called sulphate of potash (SOP), arcanite, or archaically potash of sulfur, is the inorganic compound with formula K2s04, a white water-soluble solid. it is commonly used in fertilizers, providing both potassium and sulfur.

    Other Names: SOP
    Potassium (K) fertilizer is commonly added to improve the yield and quality of plants growing in soils that are lacking an adequate supply of this essential nutrient, Most fertilizer K comes from ancient salt deposits located throughout the world. The word “ potash" is a general term that most frequently refers to potassium chloride (Kcl), but it also applies to all other K-containing fertilizers, such as potassium sulfate (K?s0?, commonly referred to as sulfate of potash, or SOP).

    Agricultural Use

    Potassium is needed to complete many essential functions in plants, such as activating enzyme reactions, synthesizing proteins, forming starch and sugars, and regulating water flow in cells and leaves. Often, concentrations of K in soil are too low to support healthy plant growth.

    Potassium sulfate is an excellent source of K nutrition for plants. The K portion of the K2s04 is no diferent from other common potash fertilizers. However, it also supplies a valuable source of S, which protein synthesis and enzyme function require. Like K, S can also be too deficient for adequate plant growth. Further, Cl- additions should be avoided in certain soils and crops. in such cases,K2S04 makes a very suitable K source.

    Potassium sulfate is only one-third as soluble as KCl, so it's not as commonly dissolved for addition through irrigation water unless there's a need for additional S

    Several particle sizes are commonly available. Manufacturers produce fine particles (smaller than 0.015 mm) to make solutions for irrigation or foliar sprays, since they dissolve more rapidly, And growers find foliar spraving of K2s04, a convenient way to apply additional K and s to plants, supplementing the nutrients taken up from the soil. However, leaf damage can occur if the concentration is too high.

    Management practices

    Growers frequently use K2SO4 for crops where additional Cl -from more common KCl fertilizer- is undesirable. The partial salt index of K2SO4 is lower than in some other common K fertilizers, so less total salinity is added per unit of K.

    The salt measurement (EC) from a K2SO4 solution is less than a third of a similar concentration of a KCl solution (10 millimoles per liter). Where high rates of K?SO??are needed, agronomists generally recommend applying the product in multiple doses. This helps avoid surplus K accumulation by the plant and also minimizes any potential salt damage.


    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. Crops that are less sensitive may still require potassium sulfate for optimal growth if the soil accumulates chloride from irrigation water.

    The crude salt is also used occasionally in the manufacture of glass. Potassium sulfate is also used as a flash reducer in artillery propellant charges. It reduces muzzle flash, flareback and blast overpressure.

    It is sometimes used as an alternative blast media similar to soda in soda blasting as it is harder and similarly water-soluble.

    Potassium sulfate can also be used in pyrotechnics in combination with potassium nitrate to generate a purple flame.
