Assessing forest soil CO(2) efflux: an in situ comparison of four techniques.
A dynamic, closed-chamber infrared gas analysis (IRGA) system (DC-1: CIRAS-1, PP-Systems, Hitchin, U.K.) was compared with three other systems for measuring soil CO(2) efflux: the soda lime technique (SL), the eddy correlation technique (EC), and another dynamic, closed-chamber IRGA system (DC-2: LI-6250, Li-Cor, Inc., Lincoln, NE). Among the four systems, the DC-1 systematically gave the highe...

متن کاملSustained effects of atmospheric [CO2] and nitrogen availability on forest soil CO2 efflux.
Soil CO2 efflux (Fsoil ) is the largest source of carbon from forests and reflects primary productivity as well as how carbon is allocated within forest ecosystems. Through early stages of stand development, both elevated [CO2] and availability of soil nitrogen (N; sum of mineralization, deposition, and fixation) have been shown to increase gross primary productivity, but the long-term effects ...
متن کاملQuantitative Comparison of In Situ Soil CO2 Flux Measurement Methods
Development of reliable regional or global carbon budgets requires accurate measurement of soil CO2 flux. We conducted laboratory and field studies to determine the accuracy and comparability of methods commonly used to measure in situ soil CO2 fluxes. Methods compared included two static techniques, sodium hydroxide (NaOH) and soda lime as CO2 traps; a multichamber open dynamic system (OC) wit...
