This May 14, 2013 photo shows train cars on the tracks that run alongside a field that local economic developers hope to see become a fertilizer plant just outside Tuscola, Ill. A company called Cronus Chemical is considering the site, part of a wave of new fertilizer plants and plant expansions being proposed around the country. New supplies of natural gas _ important for fertilizer manufacturing _ are helping drive those plans, which are also boosted by the continued strength of American corn and grain farming. This site's proximity to rail lines and to a pipeline that carries natural gas make it potentially attractive. (AP Photo/David Mercer) less
