Polysulphate Granular

Exceptional natural multi-nutrient fertilizer









Polysulphate is a natural multi-nutrient fertilizer mined as polyhalite exclusively by ICL. It provides four plant-available nutrients – sulfur, potassium, magnesium, and calcium, all in sulfate form. Naturally providing a gradual release, Polysulphate supplies balanced nutrients on demand to ensure a healthier and more productive crop. Granular Polysulphate consists of granules 2-4 mm in diameter. With excellent spreading characteristics, this is an ideal fertilizer to apply alongside straight nitrogen; it can also be applied straight or used in blends.

Polysulphate Granular is a natural product, licensed for use in organic farming systems (OMRI approved), with a particularly low carbon footprint. The entire Polysulphate Granular production process, including mining, processing, and packaging, produces just 0.029 kg of CO2 equivalent per kilogram of product. This exceptionally low carbon footprint is considerably lower than similar products, highlighting Polysulphate Granular's credentials as an excellent eco-friendly choice for growers.
