Tessenderlo Kerley
Today’s Tessenderlo Kerley is the descendent of The Kerley Chemical Company, founded by four brothers who recognized a growing demand for sulfur plant nutrition in Pecos, Texas, shortly after the end of World War II. The Kerley Brothers developed a unique process for manufacturing sulfur-based liquid fertilizers that are safe, easy to handle and can be applied through irrigation equipment. In the early 1950s, Kerley Chemical opened retail stores and began selling fertilizers to farmers, retailers and distributors throughout the western United States and midwestern corn belt.
