Measurements of soil gas efflux are key to understanding carbon and nitrogen cycling, and have helped answer research questions in fields ranging from fundamental biology to ecosystem management. Manual “static” chamber measurements have been used extensively for several decades and these data have been critical in developing our understanding of nutrient cycling in many ecosystems; however, these manual methods also have their downfalls. Now that automated chamber systems are widely available and can be coupled to highly precise  analyzers, researchers have expanded options for gas emission measurements. This case study will go through some of the key considerations when deciding whether you should switch to an automated system, keep the manual approach or use a combined approach for measurement and monitoring of soil gas fluxes.
