Abstract: 
By means of a field-study a forest-soil was exposed to metal contamination with lead, cadmium, nickel and zinc at three concentration levels for ten months. A distinct retardation of N-mineralization occurred for all metals and concentration levels compared with the control in spite of relative promotion according to rising metal concentrations with regard to lead, nickel and cadmium. This result was interpreted as an ambiguous effect in the sense of an inhibition of non-resistant N-mineralizing microorganisms associated with a metal-induced promotion of resistant strains. The more bioavailable metals proved to inhibit N-mineralization to a greater extent than the less bioavailable metals (Cd > Zn > Ni > Pb). Soil contamination by lead (500 ppm) showed no significant shift in the relative proportions of fungi and bacteria on nitrogen mineralization compared with uncontaminated soil.
