Polyhalite Best Management Practices featured in Science Societies

Polyhalite Best Management Practices as seen in Science Societies (ASA, CSSA, SSSA)  publication Crops & Soils magazine.

Commercially available from ICL as Polysulphate, we look at how polyhalite is reshaping nutrient management through a more integrated, system-level approach.

This CEU-approved piece highlights how a sulfur-driven, multi-nutrient approach using polyhalite can improve nutrient use efficiency, support soil function, and streamline fertilizer programs. Backed by field research and commercial experience, the article emphasizes practical strategies—like basing application rates on sulfur demand—to optimize crop performance across diverse systems.

Delivering potassium, calcium, magnesium, and sulfur in one application improves both nutrient balance and operational efficiency.

Polysulphate Key Best Management Practices

• Base Polysulphate application rates on sulfur demand (typically 100–200 lb/ac) and refine based on soil tests for K, Ca, and Mg contributions.
• Apply pre-plant, planting or early-season broadcast to align with early-season crop needs
  • Low leaching risk and gradual release makes it appropriate for fall applications, particularly for crops like canola, with early spring sulfur demand
• Leverage blending flexibility to simplify logistics and improve nutrient balance.
  • pH neutral; stable in blends
  • Low hygroscopic fertilizer
  • Uniform particle size
• Support nitrogen efficiency through balanced sulfate-based nutrition
