Greenfield Nitrogen, LLC is an Iowa limited liability company that is located in Northern Iowa—the heart of the U.S. Corn Belt and one of the largest ammonia consuming regions in the world. Our company is sponsored by farmers and led by farmers.
Greenfield Nitrogen is in the final stages of developing a regional-sized anhydrous ammonia manufacturing and storage facility that will supply farmers with direct application ammonia.
Our Story Has Not Changed
Farmers have few ways to reduce their crop input costs, especially given fertilizer is a significant portion of these costs.
U.S. farmers are paying persistently high fertilizer prices, which is driven by limited supply choice, a world supply / demand imbalance, and a cumbersome and costly supply chain. As a result, many farmers are left with eroding, or often, negative margins.
That’s why Greenfield Nitrogen is developing a regional-sized ammonia manufacturing and storage facility near Garner, Iowa. In early 2026, we will be sharing information on how farmers and individuals can participate in the nitrogen fertilizer supply chain.
