A method for the inventory of root biomass and below-ground bioelement pools in forest stands is presented. The study was conducted in a 100-yr-old Norway spruce stand in the ARINUS Experimental Watershed, W. Germany. The sampling area around a tree was defined by the Thiessen polygon method. Sampling with a root auger only permitted an inventory of fine roots down to a soil depth of 30 cm. Only the excavation of a whole tree made it possible to quantify bulk root biomass and element pools.
