| Method |
P.1420 middle column bottom paragraph: "Here, [investigators] present results from a controlled, replicated in situ deep mineral soil warming experiment to determine the response of an undisturbed whole-soil profile to warming (+4°C). [They] tested the sensitivity of soil CO2 production to warming from 0 to 100 cm and whether there was acclimation over 2 years. [They] used radiocarbon to determine whether warming resulted in the decomposition of older SOC [soil organic carbon]. This study was located in a coniferous temperate forest in soils classified as alfisols containing 16.6 ± 1 kg C m^−2 in the top meter." |
