Summary

We conducted investigations about the effects of different farming systems and seminatural habitats on beneficial organisms. On one hand, it was performed in a long-term comparison trial of different farming systems (DOC-trial) and on the other hand also on the farm Ievel. Beneficial artbropods and earthworm populations were mostly investigated in arable fields and also in the adjacent field margins and seminatural habitats.
In most cases, carabid populations of organic fields were richer in species and abundance and also the abundances and biomasses of earthworms were greater than in the integrated farmed plots. The spider fauna did not differ so significantly in dependance of tbe farming intensity. Endangered and rare carabid and spider species were generally more abundant in the organic fields. Summerand winter data have sbown that seminatural habitats and field margins play a key role as refugia and overwintering sites for many beneficial artbropods. In conclusion tbe data showed that organic farming in combination with seminatural habitats and field margins are crucial factors for a sustainable conservation and enbancement of the indigenous beneficial fauna on the agriculturalland.
