Economic Impact

Mosaic in Polk County is more than operational, it’s foundational to local economic strength. In 2025, Mosaic generated nearly $750M in economic activity through employee wages, contractor salaries, and significant tax contributions that support local services and infrastructure. With nearly $6.8M spent in reclamation, and extensive agriculture investments that support grazing, hay and sod production, we continue to revitalize the land for long-term productive use.

Located in Polk County, Streamsong Resort is a premier golf destination built on formerly mined land, showcasing how environmental restoration can create new economic and recreational opportunities. Developed by The Mosaic Company, the resort transforms this unique landscape into a world-class experience while supporting local jobs and tourism. Today, Streamsong provides a $36 million impact to Polk County, and stands as a powerful example of how responsible land reclamation can benefit both the environment and the community.

Completed UIC well sites (shown above) have a limited above-ground footprint required for operation. Colored piping is used to identify different injected water sources, such as treated wastewater, reclaimed water or municipal water.

Underground Injection Control (UIC) is a proven, highly regulated technology that adds resiliency to Mosaic’s comprehensive water management strategy. Used safely in Florida for decades, UIC allows treated, non-hazardous water to be managed in deep underground formations that are separated from drinking water sources by impermeable rock and clay.

Phosphogypsum, also known as PG, is a byproduct created during the phosphate fertilizer manufacturing process. In the U.S., PG is generally required to be stored in large, regulated stacks. But based on recent research, PG can be reused for more than 55 applications, including agriculture, forestry, and environmental projects. In 2025, Mosaic received EPA-approval to construct the PG Pilot Road Project at New Wales and test PG in real-world conditions as a sustainable alternative for road base materials. PG can potentially replace the use of limited resources and reduce the need for gypstacks, allowing for land to be put to more productive use.
