Relationships between the MWD and aggregate fractions (a–f) and soil active organic carbon components (g–j). MWD mean weight diameter, LMA macroaggregates, MIA microaggregates, SCA silt + clay fractions, LMA-C macroaggregate C, MIA-C microaggregate C, SCA-C silt + clay C, POC particulate organic carbon, EOC easily oxidizable organic carbon, DOC dissolved organic carbon, MBC microbial biomass carbon. Significant correlations are denoted by *p < 0.05; **p < 0.01; ***p < 0.001.
