Simplot’s Mining and Manufacturing operations began in the mid-1940s


Seeing a great need for phosphate fertilizers produced in the western United States, J.R. Simplot was determined to explore untapped phosphate reserves and develop processing and production capabilities.

To complement being a major supplier of crop nutrition, Simplot has expanded manufacturing also to include feed phosphates, industrial products, turf and nursery fertilizers, and the mining of silica sand.
