Earthworms play a major role in overall soil fertility and productivity. Our objective
characterize the earthworms in conventional and organic farms where soil is under
operations, crop rotation, and nitrogen applications. In the present research we compared
and organic areas in four different Hungarian sites: Zsámbok and Babat Valley in the
Hillside, Bér is in the Cserhát and Vértesacsa in the Vértes Hill. We analyzed the
1. 5-5 sample from Zsámbok and Babat Valley and 3-3 sample from Bér and Vértesacsa.
plot size was 0.25 × 0.25 m. Earthworms were counted from 20 cm deep samples in each
results show that in the organic farms the number of earthworms was higher, than in
areas, so there is difference based on the statistical analyses. Greater numbers of
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.
