The present paper deals with effects of different quantities of sewage mud, worm casting and NPK-fertilizer on the number of aminoautotrophs, aminoheterotrophs, nitrifiers and nitrogenbacters in soil sown with potatoes. Systems of fertilizing influenced the number of almost all of the examined groups of microorganisms. The highest number of almost all of them was found in the variant fertilized with worm casting compared with mineral fertilizer, introduction of sewage mud caused greater increase in the number of microorganisms. With increase in the quantity of sewage mud, the number of all examined groups of microorganisms became higher. The number of the examined microorganisms was highest in soil with a depth from 10 to 20 cm, at the end of potato vegetation; the lowest number was found in soil with a depth from 0 to 10 cm at the beginning of potato vegetation.
