abstract: Organic farming on sandy soils in Brandenburg is especially vulnerable to climate change impacts like drought and heavy rainfall. Reduced tillage is considered as one possible adaptation measure. For technical implementation the ring cutter allowing shallow non-inversion tillage with overall root-cutting is under investigation. Its effects on soil bulk density, soil organic matter content, root mass and soil water retention as well as the yield of winter rye were quantified. Results from the spring showed a significant accumulation of organic matter in the tilled top layer and both a significant increase of bulk density and a significant decrease of root mass in the non-tilled lower topsoil. Water retention in the non-tilled layer was reduced. The yield of winter rye was 27 % lower. Due to a compaction the non-tilled layer of the soil was less penetrable by roots. The showed results of only one date do not allow reasoning to a whole tillage system. In the present case it is recommended to loosen the compacted non-tilled layer with additional non-inversion tillage.
