Studies on the combined effects of beech-spruce mixtures are very rare. Hence, forest nutrition (soil, foliage) and nutrient fluxes via litterfall, throughfall (+ stemflow) and soil solution were measured in adjacent stands of pure spruce, mixed spruce-beech and pure beech on a nutrient rich site at Kreisbach, as well as in adjacent spruce and mixed stands on a nutrient poor site at Frauschereck to evaluate the impact of tree species composition (spruce versus beech) on these parameters. The highest recorded throughfall (+ stemflow) fluxes were 22.4 kg N ha−1 and 9.6 kg S ha−1 yr−1 and increased from beech over the mixed to the spruce stand at Kreisbach, but were similar for both stands at Frauschereck.
