Abstract: Aerated soils represent an important sink for atmospheric methane (CH4), due to the effect of methanotrophic bacteria, thus mitigating current atmospheric CH4 increases. Whilst rates of CH4 oxidation have been linked to types of vegetation cover, there has been no systematic investigation of the interaction between plants and soil in relation to the strength of the soil CH4 sink. We used quasi-continuous automated chamber measurements of soil CH4 and CO2 flux from soil collar treatments that selectively include root and ectomycorrhizal (ECM) my...
