The significant positive correlations between Cmic and CO2 emissions (rs = 0.78) and Cmic
and the macro-aggregate yield (r = 0.42) as detected after eight
weeks suggest a stronger effect of the microbial derived binding
agents on aggregation processes in weeks five to eight. This is
corroborated by the partly detected lower CO2 emissions in weeks
five to eight compared to weeks one to four that coincided with
higher microbial biomass C concentrations measured after eight weeks
