As a dual nutrient source, Protassium+® premium sulfate of potash is more efficient at delivering nutrients that help optimize plant growth. It delivers 50% K2O, commonly referred to as potash, and 17% sulfur in the readily available sulfate form. On top of that, it's virtually chloride-free and has the lowest salt index on a K2O basis of all major potassium sources. 

  • Avoid the burden of chloride and salt: the low salt index of Protassium+ premium sulfate of potash minimizes the risk of soil toxicity for added peace of mind and it gives growers more flexibility in application.

  • An excellent source of sulfur: Helps support plant functions that can affect yield, quality and marketability

  • Natural and pure: From Great Salt Lake in Ogden, Utah, Compass Minerals produces Protassium+ premium sulfate of potash through a 100% natural solar evaporation process.
