KMS – Potassium Magnesium Sulfate


KMS supplies water-soluble magnesium, sulfur, and potassium. While soluble it dissolves slower than other magnesium and potassium sources making it perfect for low magnesium soils that are susceptible to nutrient leaching.


  • Does not change soil pH
  • Dissolves slowly and resists leaching from the soil
  • Suitable for injection through irrigation systems.
