Potassium is the third major plant and crop nutrient after nitrogen and phosphorus. Potash is the common name for various mined and manufactured salts that contain potassium. Today, potash is produced worldwide at amounts exceeding 30 million tons per year. Potassium chloride (KCl) accounts for most of the K used in world agriculture (about 90%).

Ninety five percent of all potash fertilizers come in the form of muriate of potash (MOP), also known as potassium chloride (KCl). It contains 60-62% K 2 O (50% K+). For crops unable to tolerate high chloride contents, potassium sulfate (K 2 SO 4) is the common alternative fertilizer. This has 50% K content but also contains 16% sulfur (S).
