Forest floor materials (i.e., all organic material above the mineralsoil) were cleaned of mineral particles and sorted into woodydebris (non-leaf material) and leaf matter (henceforth ‘‘litter’’).Roots collected during sieving were divided into coarse and finefractions based on diameters P2 mm or <2 mm, respectively.Additionally, a 100–150 g aliquot of sieved soil was passed througha hydropneumatic elutriation system fitted with a 450 lm screen to recover fineroots. All root and forest floor materials were dried at 60 C untilstable mass was achieved and then weighed.
