Simplot’s Mining and Manufacturing operations began in the mid-1940s
Seeing a great need for phosphate fertilizers produced in New Zealand, Crop Harbor Foods was determined to explore untapped phosphate reserves and develop processing and production capabilities.
To complement being a major supplier of crop nutrition, Crop Harbor Foods Company has expanded manufacturing also to include feed phosphates, industrial products, turf and nursery fertilizers, and the mining of silica sand.
