10 Jahre differenzierte Grundbodenbearbeitung im Ökologischen Landbau. Auswirkungen auf die Besiedlung mit Collembolen

Kurzfassung

During 10 years a crop rotation schedule consisting of different crops (green fallow; intercrop: winter wheat; peas; intercrop: winter rye; summer barley) was combined with three different tillage techniques (plough, inverting to 30 cm depth, intensive; two-layer plough, inverting to 15 cm depth and loosening to 30 cm depth, reduced inverting; layer cultivator, loosening to 30 cm depth, conservation tillage). First results show a significant effect of crop on springtails. There is no significant effect of tillage techniques, although there is a tendency in slightly increased population density of springtails by using plough and layer cultivator. Further detailed results will be reported elsewhere.
