Some big pieces of the global agricultural chemical industry come together to form The Mosaic Company's big picture. The company ranks as one of the world's largest makers of phosphate and potash crop nutrients. Mosaic's potash operations position the company at the top of the industry, along with Uralkali and PotashCorp. Mosaic ranks as the second-largest potash fertilizer company in North America (behind PotashCorp). Mosaic's potash mines are located in Canada and the US. The company does more than 50% of its business outside North America, where India and Brazil are its biggest markets.
