Population, Politics and Potash

Approximately 90% of all potash produced is employed as a fertilizer, either directly or with nitrogen and phosphorus. The remaining 10% is utilized in the manufacture of other chemical products. The original source of potassium was wood ash, however, today the term potash refers to all commercially important salts of potassium. The world's first potash mining operation commenced in Strassfurt, Germany, circa 1860, and since that time the industry has grown steadily to its present annual output of about 30 million tons of potassium chloride products or 18 million tons of Kg0 equivalent, potassium chloride or "muriate of potash" being equivalent to 63.1 % pure KPO.
