Fertilizer industry finds its alternative energy: corncobs

By Renee Schoof | McClatchy Newspapers

WASHINGTON — American agriculture has become increasingly dependent on foreign sources of natural gas, a key ingredient in the nitrogen fertilizer that farmers use to get high yields of crops such as corn and wheat.

Now, a California start-up company is preparing to open a plant that will make fertilizer in the U.S. and reduce fossil fuel emissions from agriculture.

Nothing exotic needed, said the company, SynGest of San Francisco. The raw ingredient for the same ammonia-based fertilizer farmers have used for decades is something many already have and don't really need: corncobs.
