Differences in the temperature sensitivity (Q10) of SOM decomposition in different aggregate size fractions.
The Q10 values were calculated using an exponential equation. Values indicate the mean (n = 3); bars indicate the SD.Different letters indicate significant differences at P<0.05.

Relationship between temperature sensitivity (Q10) and incubation temperature.
The Q10 values were calculated using the Arrhenius equation.

Relationship between temperature sensitivity (Q10) and SOC quality.
The Q10 values werecalculated using an exponential equation. Values were the means (n = 3); bars indicate the SD.
