The aim of this work was to investigate the effects of different rates of organic fertilizers (farmyard manure and bio sludge) on occurrence of soil organisms with focus to species of family Carabidae.  Biological material was collected using the earth trap method, during the years 2007 to 2009. Samples were taken from five treatments: A-unfertilized; B-25t ha -1 farmyard manure; C-50 t ha -1 bio sludge; D- 50 t ha -1 farmyard; E-100 t ha -1 biosludge. Totally 60 472 individuals of soil organisms were collected from which 35 species totally. 35 720 individuals belongs to the target group Carabidae. Pseudoophonus rufipes was determined as the dominant species. The value of specific identity according Jaccard was from 58.33 to 80.95%, value of dominant identity varied from 86.58 to 96.02 % and total value of diversity was 0.9559t.
