Created from a naturally, occurring multi-nutrient mineral, Polysulphate is the foundation of our Polysulphate based fertilizers.
What is Polysulphate?
Polyhalite (K2Ca2Mg(SO4)4 • 2H2O is a naturally occurring mineral fertilizer, mined exclusively by ICL and packaged and sold as Polysulphate®. It is soluble, plant-available, and easy to blend and spread, making it a cost-effective multi-nutrient solution.
Deposited in the earth 260 million years ago, each Polysulphate granule naturally contains Sulfur, Potassium, Calcium and Magnesium – four of the six essential macro-nutrients required for optimal plant growth. Polysulphate is mined, crushed, and screened ready for use, giving Polysulphate its naturally low carbon footprint.
Polysulphate—a better source of Sulfur
As a naturally occurring sulfate-based multi-nutrient, Polysulphate—available as a granule or powder— requires no chemical separation or industrial processing, delivering high agronomic value for low environmental impact. Low-chloride, low salt index, neutral pH and no liming effect make it a safe choice even for sensitive crops.
How does Polysulphate work?
Providing a season-long source of plant-available nutrients, Polysulphate’s gradual release pattern safely meets peak plant demand and improves nutrient use efficiency while reducing risks of leaching. Studies show the extended sulfur availability not only increases nutrient uptake, but improves nitrogen use efficiency. Since nutrients are readily available and evenly distributed for optimal plant uptake, Polysulphate is proven to produce a healthier and more productive crop across a wide variety of soil types.
Can Polysulphate be blended with other products?
The combination of Polysulphate with other nutrients results in fertilizers capable of providing even more nutrients in a single, extended-availability granule. Explore our Polysulphate based fertilizers to find out how they will help your crops achieve their potential.
Since 2010, hundreds of field trials have been conducted worldwide demonstrating Polysulphate’s efficacy in improving both crop yield and quality.
