| In recent years, an increasing market for blueberries has developed in Switzerland. Blueberries are well suited for organic production because few disease and insect pests are currently found under Swiss conditions. Soil conditions present the greatest obstacle to blueberry cultivation in that Swiss soils are often too alkaline and have low soil organic matter content. During a nine-year (1998–2006) field experiment on an alkaline soil, we tested the feasibility and plant performance of three peat-free cultivation systems (deep ditch, flat ditch, raised bed) and two acidification methods (sulfur or citric acid versus an untreated control). Cultivars were ‘Bluecrop’ and ‘Reka’. The vegetative growth of the bushes was not significantly affected by the... |

| Production of Vaccinium corymbosum L. is limited to acidic soils with high organic matter content. This specific soil requirement is limiting the possibilities to cultivate V. corymbosum L. in many regions of Central Europe. The aim of this study was to overcome the limiting production factors occurring under the soil and climate conditions of Switzerland: (1) evaluation of natural growing substrates without peat as required for organic production; (2) adjustment of the optimal pH in the growing substrate; (3) regulation of water issues (water quality and mulching) and (4) development of a suited planting system. Pine sawdust was evaluated to be the best alternative growing substrate compared to peat moss. Optimal pH adjustment in pine sawdust substrate... |

| 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... |

| Versuchsanordnung Der Versuch wurde bei Äpfeln der Sorte Pinova durchgeführt. Es handelte sich um die 3. Lese (12. Okt. 2003), da diese erfahrungsgemäss am meisten Gloeosporium gefährdet ist. Wir haben alle Behandlungen in einer 200 l Wanne (gefüllt mit 70 l Wasser) durchgeführt. In der Behandlung mit heissem Wasser wurde die Wassertemperatur durch Nachfüllen stabil zwischen 51.5 und 52.3°C gehalten. In den Behandlungen mit den Produkten "Jet 5" und Wasserstoffperoxyd haben wir die Produktkonzentrationen nach der Behandlung jeder Repetition durch Analysestäbchen von Merckoquant kontrolliert und je nach Bedarf mit dem jeweiligen Produkt nachgefüllt. Es wurden Fruchtkistchen von je 25 Früchten in 6 Wiederholungen pro Verfahren getaucht.... |
