    Earthworms play a major role in overall soil fertility and productivity. Our objective was to characterize the earthworms in conventional and organic farms where soil is under various tillage operations, crop rotation, and nitrogen applications. In the present research we compared conventional and organic areas in four different Hungarian sites: Zsámbok and Babat Valley in the Gödöllő Hillside, Bér is in the Cserhát and Vértesacsa in the Vértes Hill. We analyzed the following replicates: 1. 5-5 sample from Zsámbok and Babat Valley and 3-3 sample from Bér and Vértesacsa. Individual plot size was 0.25 × 0.25 m. Earthworms were counted from 20 cm deep samples in each plot. The results show that in the organic farms the number of earthworms was higher, than in the conventional areas, so there is difference based on the statistical analyses. Greater numbers of earthworms were found in the organic farms compared to the conventional plots regardless of cropping or N treatment. The conventional tillage may have killed worms in the surface or caused the worms to move deeper in the soil profile. In the no-tillage and low-tillage plots in organic farms a greater source of food was available for the earthworms and they were minimally disturbed.
