Physiological and biochemical methods for estimaging soil microbial biomass are usulay calibrated against methods and parameters. However, while calibrations are usually made over soils with a very wide range of microbial biomass values (across a wide geographical range) they are often used to assess relatively small differences in microbial across a narrower range of microbial biomass values (across a smaller geographical area, e.g. within a single field), where their reliability may be considerably less. We investigated the abilities of three methods of quantifying microbial biomass, i.e. substrate-induced respiration(SIR), fumigation-incubation(FI) and fumigation-extraction(FE) to serve as predictors of each other across two geographical scales, i.e.across 12 sites over an area of ~100 x 100km; and within each of these sites (12 samples per site) over an area of 0.3 ha each. Over the larger scale, relationships between pairs of methods were strong, with R2 values always > 0.90 However, over the small scale, correlations between pairs of methods were variable and only significant for those sites in which spatial variability in soil organic matter was relatively high. Uncertain relaionships between SIR and the fumigation-based methods may be expected because they apply to different subsets of the soil biomass(i.e. glucose-responsive vs chlroform-sensitive) However, weh suggest that FI and FE are sometimes weakly correlated because the FI decompostion constant kc and the FE constant kEc vary...
