| Abstract: | The decay of Escherichia coli in a sandy loam soil, amended with enhanced and conventionally treated biosolids, was investigated in a field experiment following spring and autumn applications of sewage sludge. Control soils, without the application of biosolids, were also examined to determine the background indigenous populations of E. coli which are present in the environment. The survival of indigenous E coli and populations of E coli applied to soil in biosolids, is assessed in relation to environmental factors influencing pathogen-decay processes in soil. |
