Differences in means among Locations are denoted with different letters and represent statistically significant differences (Tukey post hoc P ≤ 0.05). (Units – Soil moisture (g H₂O^–1 g soil^–1), microbial biomass C and extractable organic C (μg C g soil^–1), total soil C & N (weight%), soil δ¹³C and δ¹⁵N are the isotopic composition of carbon and nitrogen in the conventional δ-notation (per mil, ‰) relative to Vienna Pee Dee Belemnite (VPDB) for carbon and relative to air for nitrogen.
