POLYSULPHATE (POLYSULPHATE)

The power of four elements in a single granule

Polysulphate from ICL Europe is not just a mineral fertilizer; it is a unique natural mineral (polyhalite) mined exclusively in the UK. Unlike blended fertilizers where nutrients are simply mixed, all components here are locked within a single crystalline structure. This ensures a consistent, uniform release of nutrients into the soil.

Why do professional growers choose Polysulphate?

• Prolonged effect: Thanks to its gradual solubility, nutrients remain available to the plant over an extended period, minimizing leaching losses, especially in areas with high rainfall.
• Comprehensive composition: A rich blend of sulfur (48% SO3), potassium (14% K2O), calcium (17% CaO), and magnesium (6% MgO) provides the essential foundation for photosynthesis and improved cell wall strength.
• Low salt index: Its low salt profile makes it safe to use even for sensitive crops when applied near the root zone.

This fertilizer is ideal for those who aim to improve both yield quantity and crop quality. The calcium and magnesium content is crucial for the visual quality of potatoes and vegetables, while the sulfur directly boosts nitrogen uptake, making your overall nutrient program more efficient.

Application guidelines

The optimal strategy is base application during spring cultivation. With an application rate of 100–300 kg/ha, it provides balanced nutrition throughout the entire growth cycle. Polysulphate is indispensable for rapeseed, maize, and cereals, where demand for sulfur peaks during rapid growth phases. The product is classified under hazard class 3, requiring standard field safety precautions.

Strengths: high agronomic efficiency, prolonged nutrient supply, sustainable extraction. Weaknesses: the absence of nitrogen and phosphorus requires careful combination with other fertilizers on nutrient-depleted soils.
