FARGO, N.D. (AP) — Corn growers and fertilizer industry officials are considering building a $1 billion plant in the upper Midwest that could produce enough nitrogen fertilizer to feed about 12 percent of the corn and wheat acres in the Dakotas and Minnesota.

Organizers have completed a feasibility study and are evaluating potential sites in the three states, according to the North Dakota Corn Growers Association. They also are doing business planning and will be setting up a structure that would enable farmers to invest, Executive Director Tom Lilja told The Forum newspaper (http://bit.ly/MAEyNX ).
