Use

Potassium chloride (KCl), also known as muriate of potash, is generally blended with other components to make it a multinutrient fertilizer. It is a white crystalline solid, available in fine, coarse and granular grades. It is the least expensive carrier of potassium in the fertilizer market. This important fertilizer contains about 48 to 52% plant food as potassium and about 48% chloride. Coarser potassium blends well with granular N-P compounds to form an NPK-blended multinutrient fertilizer. At least 78 % of the potassium salts are estimated to be consumed worldwide, in the form of potassium chloride, and over 90% of all processed potassium is used as fertilizer. Muck, peat and sands are generally potassiumdeficient, whereas arid soils are mostly potassium-rich, with 448 kg/ha or more of readily available potassium. Potassium chloride is neutral and totally watersoluble. It can be applied to all soils and crops that are not sensitive to chlorides. Soluble soil-potassium is adsorbed and retained by soil colloids and thus prevented from leaching. Roots take up potassium in the ionic form. Potassium chloride is best applied either while sowing or prior to it. However, when soils are light or coarsetextured, the applied potassium may be lost through leaching. So, it is preferable to apply potassium in split doses. On heavy soils, the fertilizer is placed advantageously in bands, as in the case of phosphatic fertilizers. Potassium chloride is manufactured from potash minerals or brine. Sylvinite, which is a mixture of potassium chloride and halite, is the major potash mineral used for potassium chloride manufacture. A large percentage of potassium chloride is mined and refined either by the floatation or crystallization process. Both processes, of which the floatation process is more common, involve the separation of potassium chloride from sodium chloride. Fine potassium chloride is a freeflowing material which does not cake in dry places.
