Soil properties differently influence estimates of soil CO2 efflux from three chamber-based measurement systems
Soil CO2 efflux is a major component of net ecosystem productivity (NEP) of forest systems. Combining data from multiple researchers for larger-scale modeling and assessment will only be valid if their methodologies provide directly comparable results. We conducted a series of laboratory and field tests to assess the presence and magnitude of soil CO2 efflux measurement system · environment int...

متن کاملDiffusion-based Soil Respiration Chamber Measurements
This application note contains general information about soil respiration and discusses some issues worth considering while conducting measurements with soil respiration chambers. Some basic hints and guidelines on how to use a GMP343 in a soilrespiration chamber for CO2 flux measurements in the surface-atmosphere boundary layer are also given. The primary mechanism for transport of CO2 from th...
متن کاملEffects of experimental drought on soil respiration and radiocarbon efflux from a temperate forest soil
Soil moisture affects microbial decay of SOM and rhizosphere respiration (RR) in temperate forest soils, but isolating the response of soil respiration (SR) to summer drought and subsequent wetting is difficult because moisture changes are often confounded with temperature variation. We distinguished between temperature and moisture effects by simulation of prolonged soil droughts in a mixed de...
