Polysulphate® is a multi-nutrient, natural fertilizer mined exclusively by ICL in the UK. It provides four plant nutrients – sulfur, potassium, magnesium, and calcium that contribute to optimum plant performance. Polysulphate Standard is our finest grade and is ideal for direct application in the fields. Delivering superior yields and quality for improved profitability, Polysulphate has a neutral pH, low salt index and is low in chloride, making it an ideal fit across various crops and soil types. It is also excellent as a raw material for NPKS production. Adding Polysulphate into granulated PK and NPK fertilizer production incorporates additional sulfur, magnesium, and calcium into the product. Standard Polysulphate provides added value by replacing any fertilizer filler with valuable plant nutrients. Incorporating Polysulphate as a raw material in fertilizers better meets the needs of crops while perfectly matching soil types and climatic conditions.
