MICROBIOLOGICAL ANALYSIS OF LESSIVE SOIL FERTILISED WITH ANIMAL WASTE

ABSTRACT



The present research aimed at defining the survival rate of faecal bacteria selected in the lessive soil fertilised with cattle slurry. The field trials over dry and moist summers involved slurry at the amount of 3 l.m-2 with the suspended matter of S. senftenberg, E. coli and faecal streptococci. Soil was sampled from different depths prior to the application of slurry, a week after the application, and then four times with monthly intervals. On average over the total soil profile over the dry period, the survival time of E. coli amounted to 17.7 weeks, faecal streptococci – 18.7, while Salmonella bacilli - 14.1 weeks. Over the moist period, it was much longer and amounted to 26.7, 25.9 and 19.9 weeks, respectively. A prevailing number of faecal bacteria were retained in the upper layers of soil profiles. Over the dry period microorganisms migrated to the depth of 43 cm, while over the moist period - to 70 cm. The research showed that facing soil structural d
