The soil examined in this work is located in the vinicity of settlement Ilinden near Skopje; distanced 100 m from Skopje - Veles highway. Quantity of microorganisms in the soil and their enzymatic activity are indicators of soil fertility. Heavy metals in higher concentrations influence on decrease of the number of microorganisms and their activity in the soil, and in the same way, that impacts the circulation of matter and energy and thus they have negative influence on people because they are altering the environmental conditions. The purpose of this research was to examine overall heavy metal content (Cd, Pb, Cu and Zn) and the number of some of systematic and physiological groups of microorganisms (total number of microorganisms, number of ammonificators, fungi, azotobacter and actinomyces) in the soil. Examined soil is of alluvial type, carbonic oglejana subtype. Overall heavy metal content in the soil is within permitted concentrations (Webber, 1984). Also, total number of examined microorganisms is within optimal values (Pochon and Tardieaux, 1962).
