• The microorganisms concerned with a higher ratio of biological nitrogen turnover in upland field soils applied with large amounts of raw liquid livestock feces were searched for using a newly developed genetic analysis system and method. In upland field soils, the flora of proteolytic bacteria, denitrifying bacteria, and bacteria isolated on peptone-polymyxin medium changed in relation to the amount of the applied liquid feces (120 t ha<SUP>-1 </SUP>y<SUP>-1 </SUP>and 600 t ha<SUP>-1 </SUP>y<SUP>-1</SUP>). The isolated proteolytic <I>Serratia marcescens</I>, denitrifying <I>Salmonella</I>/<I>E. coli</I>, and non-<I>Bacillus </I>polymyxin B-resistant bacteria were non- indigenous soil bacteria typically found in the soil applied with raw feces, and their numbers were estimated to be over 10<SUP>5</SUP> CFU g<SUP>-1</SUP> dry soil after 2 months of the application. They were supposed to have contaminated the field soils from bacteria present in the raw feces that survived for a while in the fields.
