Created in 2018 as a result of the merger between PotashCorp and Agrium, Nutrien is the world's largest fertilizer producer by capacity. Nutrien produces the three main crop nutrients—nitrogen, potash, and phosphate—although its main focus is potash, where it is the global leader in installed capacity with a roughly 20% market share. The company is also the largest agricultural retailer in North America and Australia, selling fertilizers, crop chemicals, seeds, and services directly to farm customers through its brick-and-mortar stores and online platforms.
