Poly-S Release Technology

Poly-S is a sulfur-based  polymer coating that reacts to water and micro-organisms in soil, instead of on temperature. Its dual-action coating provides sulfur for additional nutrient value, encouraging improved yields and quality harvest.  As a leading controlled-release fertilizer coating it is formulated to align with plant demand.  

Why Use Poly-S Release Technology? 

• Dramatically reduce nitrogen loss to the atmosphere 
• Save on input costs 
• Maximize nutrient use efficiency 
• Add nutrient value with sulfur-coating 
• Achieve consistent longevity across multiple temperatures 
• Reduce nitrogen exposure to the soil 

How does E-Max Release Technology release? 

Influenced by moisture, when activated by water, this dual–action coating begins metering nutrition to optimize crop uptake and utilization during growth.  As moisture penetrates the coating, the nutrient core dissolves, and sulfur converts to sulfate, becoming readily available to plant roots. The nutrient core releases overtime, and eventually, the remaining sulfur coating will decay.  

ICL originally introduced our first generation of coated fertilizers in 1967. Since then, we have continued to innovate. Contact your local expert to learn more about finding the right Poly-S Release Technology CRF for you.
