CO₂-C emission fluxes and cumulative emissions at the end of incubation (day 35) in S1 (a, c) and S2 (b, d) as affected by different sized dolomite application. Error bars represent standard deviation of the mean values (n = 3). ***P < 0.001. Different letters above bars denote significant differences between treatments (LSD test, P < 0.05). See Fig. 1 for abbreviations of dolomite treatments and statistic parameters
