As a naturally occurring multi-nutrient fertilizer, POLY4 contains four of the six key nutrients necessary for plant growth: potassium, sulphur, magnesium, and calcium. Extracted from North Yorkshire, UK, this unique mineral offers a low-carbon, sustainable solution for modern agriculture.
Designed to improve both crop yield and quality, POLY4 provides a steady release of nutrients that aligns with plant uptake requirements, reducing the risk of nutrient leaching and enhancing fertiliser use efficiency.
Its chemical composition is low in chloride, making it an ideal choice for high-value, chloride-sensitive crops, while its pH-neutral profile ensures it does not contribute to soil acidification.
In addition to direct nutrient provision, POLY4 supports long-term soil health by improving soil structure and promoting beneficial microbial activity. As a multi-nutrient source, it allows farmers to simplify their fertiliser programs and optimize nutrient legacy in the soil.
POLY4 is compatible with standard farming equipment and can be used as a straight fertilizer or as a component in high-quality NPK blends. Visitors to the POLY4 stand at LAMMA 2027 can learn more about how this British-mined resource is helping to improve crop quality, maximise yield potential and support the transition toward more sustainable farming practices.
