The effect of nickel contamination on the microbial properties of soil was studied in a pot experiment. Soil samples were contaminated with nickel in the form of NiCl2 · 6H2O and NiSO4 · 7H2O at the following doses: 100, 200, 300 and 400 mg Ni2+ per 1 kg. Two types of soil, loamy sand and light loam, cropped and uncropped, were used in the study. The counts of soil-dwelling microbes: oligotrophic bacteria, Azotobacter, Actinomycetes and fungi were determined on day 14, 28, 42 and 56 of the experiment. It was found that soil contamination with nickel caused a decrease in the population size of bacteria of the genus Azotobacter, while it stimulated the growth of the remaining microbial groups, including oligotrophic bacteria, Actinomycetes and fungi. Nickel chloride exerted a more significant effect on the abundance of the studied microbial groups than nickel sulfate. Higher counts of oligotrophic bacteria, Azotobacter, Actinomycetes and fungi were observed in light loam and in cropped soil, compared with loamy sand and uncropped soil.
