Saskatchewan's potash industry extracts and processes potassium chloride (potash) used globally in fertilizers. Saskatchewan holds about 40% of world potash reserves and is among the world's largest producers. Major companies including Nutrien (formerly Potash Corporation and Agrium) and Mosaic operate mines across the province. The industry generates significant royalties, employment, and economic activity, particularly in communities like Saskatoon, Esterhazy, and Rocanville. Potash prices fluctuate with global agricultural demand and geopolitical factors. The industry faces challenges including environmental concerns about mining impacts and market competition. Municipalities hosting potash operations receive tax revenue but must also manage industrial impacts.
