New Multi-Million Dollar Fertilizer Plant Coming to Northwest Ohio

A global leader in the production of specialty chemical solutions has announced plans to construct a new plant in Northwest Ohio where it can better serve the Eastern Great Lakes region.

Tessenderlo Kerley, Inc.’s new facility in Defiance will focus on the leading liquid sulfur-based crop nutrition brands Thio-Sul®, KTS®, K-Row 23® as well as sulfite chemistries for the industrial markets.

This is a multi-million dollar investment and will create at least 17 new jobs.


“Our investment in this new manufacturing facility will service the local community and support the increased demand in the region,” said Russell Sides, Executive Vice President, Tessenderlo Kerley, Inc. “This strategic venture not only combines excellence in process technology, but also diversifies our local market position, and strengthens our sustainability goals by bringing us closer to our customers.”

Along with its ideal location in the Midwest, Tessenderlo Kerley also cited a comprehensive transportation network and a strong, highly qualified workforce as critical factors in its site location decision.


The plant is expected to become operational in the first quarter of 2024.

“We are thrilled with Tessenderlo Kerley’s decision to construct a new plant in Defiance, Ohio, which will be directly served by the Napoleon, Defiance, and Western Railway (NDW),” said Alex Yeros, President and CEO of Pioneer Lines. “Since taking ownership of the NDW, we have worked closely with local, state, and federal partners to invest over $13 million to rehabilitate the line. We made these investments with growth in mind and knowing that the NDW is strategically located to serve and connect the region’s growing economy to domestic and global markets. We are delighted Tessenderlo Kerley recognized this as well. They have been terrific partners in bringing this project to fruition and we look forward to helping them grow and thrive in Ohio.”
