Abstrakt

Research on the influence of liming and fertilization with NPK on the activity of chosen enzymes in soils contaminated with cadmium and zinc dusts was carried out in the Niepołomice Forest in the years 1988-1992. Different reactions of the particular enzymes on applied fertilization were noted; fertilization did not cause significant changes in the activity of urease and acid phosphatase but increased the activity of asparaginase or invertase and diminished B-glucosidase activity. However, the fertilization caused significant increase of dehydrogenases activity on the all investigated plots. The activity of those enzymes could be considered as a sensitive bioindicator of the soil quality changes occurring as a result of fertilization in industrial regions.
