Significant correlation coefficients (r) between soil microbial substrate properties, microbial community and substrate utilization in crop and forage production systems.

†Number in parenthesis indicates Pearson correlation p values.
‡DOC = dissolved organic carbon, F∶B ratio = fungi to bacteria ratio, PC1 = First principal component and Soil Resp. = potential soil respiration.
§PC1 explains shift in soil microbial community structure from the first to the fourth year.
