Various forms of cropping methods are all accounted for in the “Feed Emissions” bucket.
The “Feed Production” emissions category uses emissions factors developed following LCA methods (described in this paper). The emissions factors take into account USDA data on typical production practices by region. The amount of each ration ingredient is multiplied by the applicable emissions factor to generate the emissions footprint.
Essentially, the model makes assumption about cropping practices in each region. It does not ask about the producer’s unique practices.
