Franzluebbers & Stuedemann’s 2009 article “Soil-profile organic carbon and total nitrogen during 12 years of pasture management in the Southern Piedmont USA” is examined within a broader environmental context than that considered by the authors. My analysis reveals that their grazing protocol yielding the fastest rate of soil-sequestered carbon also produces an amount of methane from enteric fermentation that far outweighs any reduction in atmospheric greenhouse gas resulting from carbon sequestered by the soil upon which their steers graze.

Comparing the findings of Franzluebbers & Stuedemann to those of Huntington reveals that if the highest objective is to reduce the greenhouse gas impacts of atmospheric carbon, then forestland should remain undisturbed. Forestland that has become unproductive cropland should be returned to forest if possible, not maintained as pasture. And because the heat-trapping properties of enteric fermentation-emitted methane will far outweigh any benefits associated with increased soil-sequestered C, the least desirable option would be to manage unproductive cropland as cattlegrazed pasture, even under the best grazing management.

A more detailed treatment of the issues presented in this video is found in Mike Hudak’s essay “Claims That Livestock Grazing Enhances Soil Sequestration of Atmospheric Carbon are Outweighed by Methane Emissions from Enteric Fermentation: A Closer Look at Franzluebbers and Stuedemann (2009)” available in both HTML and PDF format at
