a Atom-% 13C of emitted CO2 during the 30-day incubation of the intact samples. Shown are means and standard errors as error bars. P values are shown for the differences between the two systems significant at P < 0.05. Total (b), dissolved organic (c), and cytosol (d) C of glucose-origin (13C) remaining in the soil after 24 h and 30-day incubation. Shown are means, standard errors as error bars, and original data as dots. Significant (P < 0.05) differences between large and small-pore treatments within the system and incubation times as determined via simple-effect F tests are marked, with P values shown above the bars. Source data are provided as a Source Data file.
