Quantifying Cradle-to-Farm Gate Life-Cycle Impacts Associated with Fertilizer used for Corn, Soybean, and Stover Production

Abstract

Fertilizer use can cause environmental problems, particular eutrophication of water bodies from excess nitrogen or phosphorus. Increased fertilizer runoff is a concern for harvesting corn stover for ethanol production. This modelling study found that eutrophication potential for the base case already exceeds proposed water quality standards, that switching to no-till cultivation and collectingstover increased that eutrophication potential by 21%, and that switching to continuous-corn production on top of that would triple eutrophication potential.
