Respired CO2-C g−1 Cbulk during the 95-day incubation in (a/b) coarse-textured and (c/d) fine-textured soil. The total respired CO2-C in soil with (b) coarser and (d) finer texture is displayed on the right (means, SDs displayed with errors bars, n = 5 independent replicates), together with the total priming effect. We report CO2-derived C per amount C in incubated samples to directly showcase the mechanistic process level. Asterisks represent significant differences between the textures (***P < 0.001, ****P < 0.0001). Statistical significance was analyzed using an unpaired two-sided t-test.
