Technical Abstract: A field study was conducted near Ft. Collins, CO evaluating irrigated continuous corn production under conventional tillage (CT) and no-till (NT) with six N fertilizer application rate treatments. Economic return response functions were developed for each tillage system and combined with net global warming potential estimates for a subset of the treatments to determine whether economic and greenhouse gas emission improvements could be achieved. Results show that economic returns can be increased while reducing net global warming potential through adoption of no-till production and at economic N fertilizer application rates.
