Adaptive Grazing Extracts Methane from Atmosphere, Canadian Study Shows

A study by University of Alberta biologists shows that adaptive multi-paddock (AMP) grazing extracts methane gas from the atmosphere, locking it inside the soil through microbial activity. The study, “Adaptive Multi-paddock Grazing Lowers Soil Greenhouse Gas Emission Potential by Altering Extracellular Enzyme Activity,” was published in Agronomy. Researchers compared the fluxes of greenhouse gases, including carbon dioxide, methane, and nitrous oxide, from soils of AMP-grazed grasslands to paired neighboring non-AMP-grazed grasslands across a climatic gradient in Alberta, Canada. Among other results, the study found that methane uptake was 1.5 times greater in soils from AMP-grazed than non-AMP-grazed grasslands.
