Methane consumption in tallgrass priaire under grazing management
Abstract
Beef production results a large emissions of methane. Soils in native tallgrasse prairie can be a methane sink. We examined the methane flux for native tallgrass prairie with annuually buned and patch burned management. Methane flux was measued from static chambers for 3.5 years. Burning regimes included one site annually burned, and two sites with patch burned every three years on offset years. Data gathered since 2014 implies CH4 are consumed on grazed grassland soils with an increase in consumption with patch burning. Greatest consumpton occurred during the summer and lowest uptake occured in the winter. Addiitonal research indicated that N inhibited methane consumption in the prairie soils. The mechanism for the increase consumption in patch burned grassland tremains to be determined.
