Regenwurmzönosen als Indikatoren der Bodenfruchtbarkeit am Beispiel weinbaulich genutzter Flächen

The presentation comprised first results of the evaluation of a sampling of earthworm populations at 8 sites of vine growing farms in Palatinate, Rheinhessen, Baden and at the Mosel river. The sites had been selected to cover criteria like the range of total copper contents and soil properties in the upper soil layer (0-20 cm), and practical aspects of sampling. Total abundance revealed to be a rather insensitive parameter at lower or medium copper loads. The relative distribution of abundance to life-forms and especially species diversity were much more sensitive parameters.
