The penetration of bovine enterovirus, LCR - 4 strain deep into soil profiles in the field conditions was researched. Three soil types were selected: podzolic soil, black earth and browned black earth. The soils differed considerably in respect to their physical properties and chemical analysis. The best conditions for drainage were observed in podzolic soil, whereas the worst - in browned black earth. Experimental plots were being sprinkled with the 1:1 mixture of bovine enterovirus (at the concen-tration of 1x106.0 TCID50/1 ml) and slurry. The enterovirus researched, in any soil, migrated to the depth of 7.5 to 10 cm. The highest titres were observed in the surface layers of black earth and podzolic soil (0-2.5 cm). They differed from 102.72 - 104.27 TCID50/g of the soil. With depth the titres decreased, with slight fluctuations observed.
Key words: bovine enterovirus, slurry, virus migration, podzolic soil, black earth, browned black earth.
