Fig. 5. Relationships between microbial biomass C (mg kg^-1) measured by different methods. MIE: microwave irradiation-extraction method; SIR: substrate-induced respiration method; CFE: chloroform-fumigation extraction method; and CFI: chloroform-fumigation incubation method. r_0.05 = 0.36, r_0.01 = 0.46 when n = 30; r_0.05 = 0.42, r_0.01 = 0.54 when n = 22. The open circles represent soils with pH > 7.
