What is Comparative Study of Soil Respiration Partitioning Methods for Herbaceous Ecosystems about?

Soil CO 2 efflux is a complex flux composed of autotrophic and heterotrophic sources of the CO 2 . To correctly estimate whether soil is and will be acting as a sink or a source for atmospheric CO 2 , these two principal components should be studied separately. This is because they respond differently to biological and environmental drivers. Studies which compare partitioning methods of soil CO 2 in one single study using unique measurement equipment are lacking instead. In this study we attempted to compare three partitioning methods of soil CO 2 efflux: mesh exclusion, combined SIR and regression method and to choose the most appropriate for herbaceous ecosystems (e.g. grasslands and urban lawns). Mesh exclusion and combined SIR demonstrated comparable results in determination of autotrophic and heterotrophic contribution to CO 2 efflux and the methods were defined as suitable. Regression method necessitates ulterior improvements prior application in herbaceous ecosystems.
