GROWMARK has acquired a minority equity stake in Wabash Valley Resources (WVR), supporting construction of the developer’s ammonia fertilizer plant in West Terre Haute, Indiana, CropLife reported. The investment also enabled the first drawdown under WVR’s US Department of Energy loan, linking the cooperative’s participation to the release of project financing. The report did not disclose the investment’s value or the size of GROWMARK’s ownership interest.

The facility is designed to produce 500,000 tonnes of anhydrous ammonia annually, with commercial operations expected to start in 2029. According to CropLife, the project is intended to provide a new domestic fertilizer source for farmers in the Eastern Corn Belt. Those figures describe planned capacity and the expected operating timetable, rather than output already available to the market.

GROWMARK chief executive Mark Orr presented the investment as a way to establish an independent ammonia source nearer to farmers and cooperatives served by the business. He described the commitment as a long-term effort to support domestic supply reliability and the competitiveness of GROWMARK’s member-owners. The cooperative has crop nutrient and logistics operations, and the report linked its involvement in WVR to its interest in expanding fertilizer manufacturing close to the agricultural communities it serves.

WVR chief executive Dan Williams characterised GROWMARK’s participation as an important step in advancing the project after years of development. He thanked the Department of Energy and its Office of Energy Dominance Financing for their role in completing the transaction. Williams said WVR’s attention was now on safe construction and ultimately supplying US-made fertilizer to farmers. Both executives framed the investment around future supply benefits; the immediate developments reported by CropLife are the minority equity commitment, the initial loan advance and support for construction ahead of the planned 2029 start.
