Agriculture generates about 10% of total greenhouse gas emissions. Management practices can stimulate emissions of carbon dioxide and nitrous oxide through fossil fuel use, nitrogen fertilizer application, and soil disturbance, resulting in multiple opportunities to reduce emissions from farm fields. Changes in crops, tillage practices, and N fertilization all provide means for greenhouse gas reductions in farming systems.
Calculate the greenhouse gas impact of different farming systems
Choose a county to the right to begin. The following screen will present an estimate of the greenhouse gas cost of a corn-soybean rotation for that county. You’ll then be able to change crops, tillage systems, and fertilizer rates to see how management might be adjusted to minimize greenhouse gas impacts and maximize returns in the emerging greenhouse gas markets.
