Using the substrat-induced respiration method (SIR) in three different litter layers (L, F and H) of a beechwood, the influence of litter fragmentation on the microbial biomass was investigated. Leaf litter with four different sizes classes (inact leave, fragmented < 100 mm¬, < 25 mm¬, < 5 mm¬) was amended with glucose solution (80000 ppm) to achieve a 'maximum initial response'. SIR was maximized at the size class < 25 mm¬.
