Since 1880, Rosier is producing quality and trustful fertilizers. We are not only producing complex granulars but also speciality fertilizers like liquids and water-soluble fertilizers. In 2022, Rosier was acquired by YILDIRIM and became part of YILFERT Holding, marking a new chapter in its rich history. This strategic move further strengthened Rosier’s position in the global market, allowing the company to better serve customers with top-quality products and expert advice, through a keen focus on quality, reliable execution, and long-term partnerships. We are 140 employees driven by the same objective: to offer the perfect fertilizer to our customers. We do not only offer the product, we also offer a support to our customers to find the best product, on the best crop at the best time. Our activities take place on two production sites, Moustier (BE) and Sas Van Gent (NL), and we are supplying about 120 countries all over the world. We are proud of actively contributing to sustainable and efficient food production on our planet. We are also committed to participating in a more responsible agriculture through innovative tools & concepts.
