We are part of Tessenderlo Kerley, Inc.
In 2005 Tessenderlo Kerley, Inc. formed, NovaSource, a business unit dedicated to manage and develop their crop protection business.
Tessenderlo Kerley, Inc. is part of Tessenderlo Group, founded in 1919 and the descendent of The Kerley Chemical Company, founded in 1947 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.
Acquisitions, ownership changes and growth guided the company through the years, while Tessenderlo Kerley established itself as a leader in the production and marketing of specialty products used in the agriculture, mining and process chemical industries. Tessenderlo Kerley is now the world’s largest producer of sulfur-based thiosulfate fertilizers.
For over 100 years, Tessenderlo Kerley, Inc. has demonstrated its commitment to agriculture through innovation, research and the development of sustainable crop protection products.
