Summary of results (P-value) of two-way factorial _ANOVA on the effects of warming and increased precipitation and their interactions on total C, total N, ratio of C to N, microbial biomass C (MBC), labile organic C, recalcitrant organic C and stable organic C at two depths of 0–10 and 10

W, warming; P, increased precipitation; WP, warming plus increased precipitation. aLabile organic C was calculated from cumulative CO2-C (mg kg−1 dry soil) evolved from 91-day incubation. P values smaller than 0.05 are bold and italics indicates marginal significance (P<0.1).
