The word "potash" comes from the Dutch word potasch, and originally referred to the wood ash that pioneers used to make fertilizer. Potash refers to potassium compounds and materials that contain potassium, the most common being potassium chloride (KCl). Potassium is the seventh most abundant element in the earth's crust, and it is the third major plant and crop nutrient after nitrogen and phosphate. About 95% of world potash is used in FERTILIZERS. Small amounts are used to make soaps, glass, ceramics, chemical dyes, drugs, synthetic rubber, de-icing agents, water softeners, and explosives. Other potash fertilizer products include potassium sulphate (K2SO4) and potassium nitrate (KNO3).
