WebDec 25, 2001 · Abstract 1. The carbon content and δ 13 C value of soil organic carbon (SOC), microbial biomass (C mic) and respired CO 2 were measured in a range of grassland soils from tropical and temperate biomes to determine if isotope effect of microbial degradation can induce a shift in isotope composition of SOC and CO 2. WebThe stable isotope delivery (SID) system consists of an isotope-mixing unit with flow control to a series of 12 independent labelling chambers. In-line CPU controlled infrared gas analysers allow automated measurement of chamber CO(2) concentrations and …
