The effect of different kind of amendments in soil polluted with Pb, Cd and Zn on soil microflora was studied in pot experoment. The farmyard manure extract, natural zsolite, NPK and NPK + straw were involved. The total biological activity and quantity of main group of soil microorganisms were determined. It was established that applied amendments influenced with a different extent the structure and function of microbial communoties. The most prononced positive effect was observed with zeolite and combination of NPK + straw, which depends of soil characteristics. The amendments have different effect on individual group microorganisms.
