A short video by Kamal Zurba from the Interdisciplinary Environmental Research Centre, Technische Universität Bergakademie Freiberg in Germany, showing the use of manual chamber techniques to determine soil and ecosystem respiration, in addition to quantify GHG emissions from soils under different land use, mainly for CO2, CH4 and N2O. For more details on the method have a look at protocol 2.2.3 Soil CO2 and other trace gas fluxes.
