The aim of the present research was to determine the survival rate and the rate of inactivation of indicator bacteria Salmonella Senftenberg W775 in soil, depending on the cultivation of selected agricultural crops. The research was carried out over 2005-2006 at the UTP Experimental Station at Mochelek. In the experiment the role of the carrier of Salmonella Senftenberg W775 bacilli was played by communal waste compost introduced into the soil environment, on experimental plots with agricultural plantation of oat, mixture of oat with yellow lupine, spring rye and a mixture of spring rye with yellow lupine. The present research demonstrated that the weekly elimination rate of Salmonella Senftenberg W775 in soil, depending on respective field crops, ranged from 0.33 to 0.46 log, while the maximum survival time of detectable microorganisms - from 18 to 24 weeks
