In order to estimate the effect of heavy metal pollution on soil microorganisms, field surveys were carried out in paddy fields, upland fields, and fallow paddy fields located in two areas with heavy metal pollution in Japan. There was no significant correlation between the viable counts of microorganisms and heavy metal content of the soils. In a polluted area, the D500 value of the fungi was higher in the fallow paddy field soils than in the paddy or upland field soils. These results suggest that the effects of heavy metal pollution on soil microorganisms vary depending on the land use
