JSC Uralkali
A shot of Vitamin K helps farmers grow bigger and better crops. Uralkali is one of the world's top producers of potash, a form of potassium carbonate commonly used as a fertilizer. The company produces 5 million tons of potash per year, or 10% of the world's supply. (Canada's PotashCorp leads the way with 10 million tons, or 20%.) Uralkali operates two mines in Russia and five production plants. The company makes about two-thirds of its total sales to just Brazil and China. Uralkali was founded in 1930 by the Russian government and privatized in 1992. In 2007 it became the country's first public chemical company.
