The research aimed at defining the migration potential for the polio enterovirus in two soil profiles (podzolic soil and black earth) fertilised with sewage. The experimental fields were being fertilised with a 1:1 mixture of effluent and atenuated polio virus, strain Lsc2ab. After 28 days samples were taken for virus-oriented research. A slight virus penetration deep into the soil profiles was observed. The highest titres were obtained in the surface layer (0-2.5 cm) and they were, respectively: for the podzolic soil - 10 5.72 TCID50/g and for black earth 104.33 TCID50/g of the soil. The polio virus did not migrate beyond the humus layer. In podzolic soil it was observed to 20-25 cm deep, however in the black earth 15-20 cm deep. The physical properties and chemical analysis of the podzolic soil were slightly more favourable for virus migration deep into the soil.
