tThis study examined the effects of metal-polluted soil on growth, biomass and uptake of trace metalsand nutrients in Alnus incana and A. glutinosa seedlings. The rate of nitrogen fixation, counts of micro-bial groups, activities of phosphomonoesterases, and phenolic compounds in soil were also determined.Seedlings of various origin were grown for 158 days in forest soil (control) and in soil from a copper smelterarea, with low nutrient content and high concentrations of Cu (1510 mg kg−1) and Pb (490 mg kg−1). Bothalder species accumulated in their roots Cu and stored Pb, Zn (A. incana ≈ A. glutinosa) and Cd (A. gluti-nosa > A. incana). Concentrations of Cu, Pb, Zn and Cd were lower in shoots than in roots. Concentrationsof Cu, Zn, Cd and Pb in leaves of both alder species were within normal ranges. Nutrient weight pro-portions P:K:Ca:Mg (N = 100) for leaves of Alnus spp. growing in polluted soil were higher than in thecontrol. Alder growth in polluted soil was characterized by slight changes in total biomass of seedlingsand nodules. Nodules stored Cu, Cd (A. incana > A. glutinosa), Pb and Zn, while concentrations of P andCa were lower in nodules than in the control. N levels in leaves of alders grown in polluted soil weregenerally lower than those of alders grown in control soils. We also recorded a reduction in the rate of N2fixation in nodules when alders were grown in polluted soil. In the rhizosphere in polluted soil, actinobac-teria (actinomycetes) and copiotrophs were less numerous, while oligotrophs were more numerous. Alsoactivities of phosphomonoesterases were strongly reduced, while concentrations of water-soluble phe-nols increased. The results suggest that both species of Alnus grow well in heavily polluted soil, in spiteof accumulation of toxic metals in their roots and nodules and a decreased rate of N2fixation.
