   Notes: Values are means (and standard deviations) of the two replicate plots for microbial biomass C (MB-C), maximum respiratory activity (MRA), C mineralization potential (C min.), net N mineralization potential (N min.) and acid phosphatase enzyme activity (Phosph.). All data are presented on a per g soil (g) and per g organic matter (gO) basis. Different letters denote significant species differences for each variable (α = 0.05).
