    Why Growers and Retailers Choose Polysulphate® (polyhalite)

    • Balanced Nutrition
      Potassium, sulfur, calcium, and magnesium released in sulfate form to support balanced uptake.

    • Low Salt, Low Chloride
      Helps protect soil health, roots, and season-long plant growth

    • Improved Nitrogen Efficiency
      Supports sulfur-driven nitrogen assimilation and nutrient use efficiency.

    • One Pass, Less Complexity
      Fewer products and fewer trips without sacrificing performance.

    • Flexibility and Choice
      Available in granular, standard (fine), and Premium (spherical prill) grades to fit a wide range of application and blending needs.

     

    Built for Modern Fertility Challenges

    From sulfur efficiency and potassium performance to nitrogen use efficiency and soil health, Polysulphate® addresses today’s most common fertility challenges with one naturally occurring, multi-nutrient solution.

    How Polysulphate® Helps You Get More From Every Acre

    1. Reliable supply, flexible application. 
      Fill your bins and simplify spring fertility planning. Polysulphate’s gradual release minimizes the risk of nutrient loss through leaching. Nutrients are available early and continue to release throughout the season, aligning supply with crop demand. Available in granular, standard (fine), and Premium (spherical prill) grades to fit a wide range of application and blending needs.
    2. A Better Source of Sulfur
      More than sulfur alone, Polysulphate (0-0-14 +19.2S, 12.2Ca, 3.6Mg) delivers balanced nutrition in sulfate form. This nutrient synergy helps fill common nutrient gaps, supports nutrient efficiency, and improves overall fertilizer performance. Field trials show Polysulphate® can improve nutrient use efficiency and help optimize NPK programs for stronger ROI.
    3. Grow More. Risk Less.
      Low-salt, low-chloride nutrients reduce early-season stress on roots and support consistent water and nutrient uptake. By improving nutrient use efficiency and resilience under variable weather conditions, Polysulphate helps reduce yield loss across seasons, soil types and growing environments.
    4. Multi-Nutrient Efficiency. One Pass.
      Improve nutrient use efficiency without adding complexity. Supplying potassium, sulfur, calcium, and magnesium together simplifies fertility programs while supporting nitrogen assimilation and overall nutrient performance. One application delivers multiple essential nutrients—reducing program complexity without compromising yield potential.
