abstract = {Lacking knowledge about the spatial heterogeneity of
heterotrophic soil respiration (Rh) hampers the prediction
of larger-scale soil CO2 efflux in patchy landscapes. The
aim of this study was to establish a cost-efficient method
for the rapid and simultaneous assessment of cumulative
heterotrophic soil respiration (CO2) at different sample
spots. For this purpose, we adapted the laboratory-based,
fully-automated Respicond VIII respirometer (Respicond) to
detect CO2 emission under field condition, installed the
device in two temperate grasslands, and compared the Rh flux
data with those obtained using the so-called dynamic chamber
method with infrared gas analyzers (IRGA). The results
revealed good agreement between both Rh measurements (Slope
= 0.89, R2 = 0.99). We conclude that adapting the Respicond
for detection of CO2 under field conditions is principally
feasible, thus providing a new tool for the simultaneous
assessment of CO2 fluxes from different soil ecosystems.},
