| Popis: | In this field study, three methods for determining soil CO2 evolution rates were compared: (1) a static chamber method and (2) a dynamic chamber method, both with gas chromatographic (GC) analysis of air samples, and (3) a dynamic chamber system using a portable infrared gas analyzer (CIRAS). The mean CO2 evolution rate in the field increased in the order static chamber-GC |
