The exchange of soil air between the soil, vegetation, and the atmosphere is an important subject in much ecological research. With respect to climate forecasts, greenhouse gases are important parameters for models and assessments. The gas exchange between the soil and the atmosphere results from numerous complex and non-linear relationships, such as physiological, biochemical, chemical, ecological and meteorological conditions. It is possible to sample soil-borne gases by means of accumulation in closed hoods, flows through open hoods or the use of special soil gas lances. The analysis of soil gases is carried out using gas analyzers.
