Nutrient contents and concentrations in relation to growth of Picea abies and Fagus sylvatica along a European transect
Mineral nutrition of Norway spruce ( Picea abies (L.) Karst.) and beech ( Fagus sylvatica L.) was investigated along a transect extending from northern Sweden to central Italy. Nitrogen (N) concentrations of needles and leaves in stands growing on acid soils did not differ significantly between cent...

Mineral nutrition of Norway spruce ( Picea abies (L.) Karst.) and beech ( Fagus sylvatica L.) was investigated along a transect extending from northern Sweden to central Italy. Nitrogen (N) concentrations of needles and leaves in stands growing on acid soils did not differ significantly between central Italy and southern Sweden (1.0 ± 0.1 mmol N g−1 for needles and 1.9 ± 0.14 mmol N g−1 for leaves). In both species, foliar N concentrations were highest in Germany (1.2 mmol N g−1 for needles and 2.0 mmol N g−1 for leaves) and decreased by 50% toward northern Sweden (0.5 mmol N g−1).

Leaf area per unit dry weight varied significantly along the transect with lowest values for Norway spruce recorded in northern Sweden and Italy (3.4 m2 kg−1) and a maximum in central Europe (4.7 m2 kg−1).
