Abstract

The Comparison of Biofuel Systems (COBS) project is a long-term, 20-acre field experiment designed to provide quantitative, side-by-side comparisons of corn- and prairie-based biofuel feedstock production systems with respect to biomass yields, liquid fuel potential, and multiple environmental impacts. The project was established in 2008 at ISU’s South Reynoldson Farm in Boone County. Here, we report on nitrate-N loss with subsurface drainage.
