New publication examines the effects of variable soil moisture and temperatures on methane consumption in landfill cover soils
A new paper published in Frontiers of Environmental Science presents findings of a combined experimental and modelling study investigating the effects of soil moisture and temperature on methane consumption in landfill cover soils. The paper is authored by Christina Lam, a former Master’s student, and co-authors include ERG members Mehdi Ramezanzadeh, Stephanie Slowinski, Olivia Penn, Philippe Van Cappellen and Fereidoun Rezanezhad, and CAAF Landfills project principal investigator Laura Hug.
In this study, a series of soil incubations were conducted to mimic variations in soil moisture and temperature resulting from seasonal dynamics and climate change and coupled with diffusion-reaction modelling simulations to observe optimal conditions for microbial methane (CH4) oxidation in landfill soil. Maximum rates of CH4 consumption were observed at moderate soil moisture and temperature conditions. These results highlight the importance of soil moisture and temperature in modulating microbial soil reaction processes and in the practical design and development of landfill cover soils.
