The natural, multi-nutrient mineral fertilizer Polysulphate is the foundation of our Polysulphate based fertilizers. Polysulphate is made from polyhalite, the 4-in-1 mineral containing sulfur, potassium, magnesium, and calcium. Polysulphate is mined, crushed, and screened ready for use, giving Polysulphate its naturally low carbon footprint. It has a natural prolonged nutrient release and is approved for organic agriculture. Its low pH, low salt index and very low chloride content makes Polysulphate a highly versatile, crop and soil-safe mineral fertilizer.
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.
