Potassium Sulphate Fertilizer, 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 K Cl, but it also applies to all other Kcontaining fertilizers, such as potassium sulfate , commonly referred to as sulfate of potash, or SOP.
Production
Potassium is a relatively abundant element in the Earths crust, and production of potash fertilizer occurs in every inhabited continent. However,  is rarely found in a pure form in nature. Instead it is naturally mixed with salts containing magnesium, sodium and chloride Mg, Na and Cl, respectively. These minerals require additional processing to separate their components. Historically, K2SO4 was made by reacting K Cl with sulf uric acid. However, researchers later discovered that they could manipulate a number of earth minerals to produce, now the most common method of production. For example, natural K containing minerals (such as kainite and schoenite) are mined and carefully rinsed with water and salt solutions to remove byproducts and produce K2SO4. The mining industry uses a similar process to harvest  from the Great Salt Lake in Utah and from underground mineral deposits.
