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. Standard Polysulphate is ideal for direct application in the fields. It is also excellent as a raw material for NPKS production. Using Polysulphate in 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. Standard Polysulphate is a natural product with a low carbon footprint, licensed for use in organic farming systems.
