Omya is a leading global producer of mineral-based products that deliver a return on investment by helping to increase cropland productivity. From soil conditioning to crop nutrition, our products are carefully developed for high reactivity, rapid response and measurable results. To better serve growers across the US, Omya has acquired MK Minerals, a privately held specialty fertilizer producer with a strong footprint in the Midwest agriculture market.

At the heart of Omya’s success is the milling of minerals to extremely fine particles, which ensures high reactivity and efficiency. Our range of products includes granulated, powder and slurry formulations, to suit different circumstances, crops and application methods.

Omya’s state-of-the-art research and development facilities in Switzerland employ 140 scientists who focus on product innovation and the continual development of processing technology. We test our products in replicated, field scale trials across the world and operate pilot plants to optimize the manufacturing process. Global quality standards ensure that customers of all our regional businesses receive products of the highest quality, purity and consistency.
