Abstract Soils represent a major global source and sink of greenhouse gases (GHGs). Many studies GHG fluxes between soil, plant atmosphere rely on chamber measurements. Different techniques have been developed over the last decades, each characterised by different requirements limitations. In this manuscript, we focus non‐steady‐state technique which is widely used for manual measurements but also in automatic systems. Although measurement method appears very simple, experience gained years shows that there are many details to be taken into account obtain reliable results. This manuscript aims share lessons learnt pass experiences order assist reader with possible questions or unexpected challenges, ranging from planning design chambers practical handling quality assurance gas data analysis. concise introduction refers more extensive Best Practice Guideline initiated Working Group Soil Gases ( AG Bodengase ) German Science Society Deutsche Bodenkundliche Gesellschaft ). The intention was collect aggregate expertise working groups research field. As compendium, intended help both beginners experts meet theoretical challenges measuring soil systems improve individual flux thus entire reducing sources uncertainty error.
