We evaluated the relationships between three techniques to estimate microbial biomass in forest humus: chloroform fumigation-extraction (CFE), total extractable phospholipid fatty acids (PLFA), and extractable DNA. There was a good relationship between PLFA and CFE (R^2=0.96), with a slope slightly different from that previously reported for mineral soils (1nmol PLFA corresponded to a flush of 3.2 @mg C released by fumigation in humus cf. 2.4 @mg C in mineral soil). There was no relationship between DNA concentration and the other two measurements of microbial biomass. This may be due, in part, to the high
