Abstract
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. During 2001-2003, samples of biological material were collected using the earth trap method. Samples were taken from five treatments (i) unfertilized, (ii) 25 t ha-1 farmyard manure, (iii) 50 t ha-1 bio sludge, (iv) 50 t ha-1 farmyard manure, (v) 100 t ha-1 bio sludge) which cover area of 9 000 m2 at experimental farm of Slovak Agricultural University Kolíňany. Totally 59 054 individuals of soil edaphon belong to 23 epigeic groups was collected from which 25 species totally 21 189 individuals belong to the target group Carabidae. The attributes of specific identity according Jaccard (IA) ranged from 45.45 to 71.43 % and those of dominant identity (ID) from 94.20 to 97.72 %. The attributes of diversity (d) achieved a level from 0.5406 to 0.8986. Harpalus rufipes (De Geer, 1774) occurring on arid to damp soil, mostly in light places, was determined as the dominant species. The attributes of individual treatments are influenced by the quantity of organic mater inputs into soil that affects the formation of well-defined communities with the characteristic species composition. A comparison of individual treatments in terms of the occurrence of zooedaphon showed that application of 100 t ha-1 bio sludge create the most suitable soil condition for zooedaphon development.
