Pearson product-moment correlation coefficients (r) were calculated for macroaggregate
yields and microbial biomass C for each sampling date
(n = 30). Spearman rank correlation coefficients (rs) were calculated
for macro-aggregate yields and CO2 emission rates for each
sampling date (n = 30) as the CO2 data were not normally
distributed. Only significant correlations (p < 0.05) are discussed.
