Beef cattle on pasture in the USA (photo credit: BEEF magazine).
A new research paper by Michigan State University scientists analyses the impacts of soil carbon sequestration on life cycle greenhouse gas emissions in Midwestern USA beef finishing systems.
• On-farm beef production and emissions data are combined with 4-year soil carbon analysis.
• Feedlot production produces lower emissions than adaptive multi-paddock grazing.
• Adaptive multi-paddock grazing can sequester large amounts of soil carbon.
• Emissions from the grazing system were offset completely by soil carbon sequestration.
• Soil carbon sequestration from well-managed grazing may help to mitigate climate change.
The following excerpts (excluding references) are from the paper.
‘Beef cattle have been identified as the largest livestock-sector contributor to greenhouse gas (GHG) emissions. Using life cycle analysis (LCA), several studies have concluded that grass-finished beef systems have greater GHG intensities than feedlot-finished (FL) beef systems. These studies…
