Phosphate Operations in Louisiana

 
Phosphate crop nutrients play an essential role in helping feed our growing global population. Phosphate is also an essential component of all living things – and is used in a variety of consumer products. Mosaic operates its Faustina and Uncle Sam facilities in St. James Parish and can be located on our global presence map. Both facilities began operations in 1968.

Phosphate rock shipped in from Florida and other parts of the world must be converted to a water-soluble form in order to be used as a crop nutrient. This manufacturing process begins when the rock is finely ground to uniform size. Sulfuric acid is then added to form phosphoric acid, which is concentrated through evaporation, reacted with ammonia, and granulated to produce two basic phosphate/nitrogen crop nutrients - diammonium phosphate (DAP) and monoammonium phosphate (MAP). Our products are primarily sold in bulk to distributors who blend and sell them directly to farmers. To the average consumer, phosphate is the middle number commonly found on bags of lawn and plant fertilizers (e.g. 8-8-8). Those three numbers represent levels of nitrogen, phosphorous and potassium— three essential nutrients—in that order.

In Louisiana, Mosaic’s fertilizer manufacturing process begins on the east side of the Mississippi River at our Uncle Sam Facility, where a turbo generator harnesses excess heat from sulfuric acid production. The cogeneration process allows Mosaic to harness “clean and green” energy. Uncle Sam produces phosphoric acid, which is then shipped across the river to our Faustina facility. Mosaic produces ammonia to make MAP, DAP and its premium MicroEssentials® products at Faustina.

Mosaic works with a variety of vendors and suppliers in the River Parishes and throughout Louisiana. Contact one of our facilities to learn more about becoming a vendor, contractor or supplier.

Mosaic is relentless in the pursuit of safety. Our goal is to ensure that every one of our employees and contractors returns home safely at the end of their work day. We also believe lasting success comes from making smart choices about our stewardship of the environment, how we engage our people, and how we manage resources.
