Summary

Organic fruit and wine producers have to use organically produced plant material if
available on the market. To support and enhance this difficult production sector a
project was started in 2003 funded by the Coop Naturaplan Fonds. The improvement
or development of better methods for fertilization, soil management, growth regulation
and plant protection are the main objectives of this project. In our trials with apple
trees we found that an intensification of the nitrogen fertilization including application
of foliar fertilizers did not result in a better quality of young trees. The use of the
bacterial bio-fertilizer BactoFil® Professional-2 without any nitrogen fertilization
increased the tree quality under our conditions. In another experiment comparing
cover plant and tilled soil, we obtained a better quality of the young trees where soil
was covered with Bromus tectorum. In the grape-vine nursery trials we found that the
main problem, the Plasmopara viticola disease, can be sufficiently controlled with the
available organic plant protection product such as copper, sulphur and acidified clay
powder. The quality of the organically produced vine-plantlets was equivalent with the
conventional plants.
