10 Jahre differenzierte Grundbodenbearbeitung im Ökologischen Landbau. Auswirkungen auf die Besiedlung mit CollembolenUrsula K.BassemirauthorDuring 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. Soil biology Soil tillage2005kassel university press GmbH, KasselConference paper, poster, etc.
