This tool estimates carbon footprint and greenhouse gas (GHG) emissions for farms and ranches. Users input current farm or ranch management practices, and the tool uses information on climate and soil conditions from USDA databases to run a series of models for potential sources of GHG emissions and climate change impacts. It then suggests alternative future management practices for sequestering more atmospheric carbon or reducing GHG emissions. Required inputs describe field and livestock management practices and include cropping sequence and approximate planting and harvest date, type of tillage system, irrigation method and application rate, residue management, and livestock herd size and composition. The Energy Module allows users to calculate reductions in GHG emissions based on anticipated fuel savings.
