| Organic farmers often use winter wheat (Triticum aestivum L.) cultivars that have been bred under conventional high-input conditions. We test the hypothesis, whether old and organically bred cultivars are better adapted to low-input conditions through a better functioning of the symbiosis with arbuscular mycorrhizal fungi (AMF). Our aim is to assess the nutrient acquisition potential of old, new and organically bred winter wheat cultivars and to identify the role of AMF for nutrient uptake and growth. In October 2006, an experiment with 10 wheat cultivars was superimposed to all four field replicates of the DOK long-term experiment, comprising four different treatments with increasing nutrient input: unfertilized, biodynamic low and moderate intensity and... |

| The environmental impacts of the conventional and organic farming systems practised in the DOC trial (organic-dynamic, organic and conventional farming) have been assessed by the SALCA life cycle assessment method. Both organic farming systems were more favourable for the environment in all investigated impacts per area unit. When analysed per product unit, clear advantages of organic farming were found for ecotoxicity and the use of mineral resources, while energy use and eutrophication were similar to conventional farming. Reducing fertilisation by 50% led to lower or equal environmental impacts for all systems, depending on the impact category and the functional unit. The analysis of single crops revealed large differences that are partly... |

| Organic and conventional cropping systems differ in the nature and amounts of nitrogen (N) inputs, which may affect efficiency and sustainability of N use. In the DOK (bio-Dynamic, bio-Organic, Konventionell) field experiment, organic and conventional cropping systems have been compared since 1978 at two fertilization levels. Nitrogen inputs via manure and/or mineral fertilizers, and N exports from plots with harvested products have throughout been recorded. For all treatments, N outputs with harvests have exceeded the inputs with fertilizers. Over the past years, symbiotic N2 fixation by soybean and clover grown in the trial has additionally been assessed, indicating average annual inputs of about 100 kg ha-1 yr-1 of N fixed from the atmosphere.

| Long-term trials are necessary not only to judge agronomic and ecological indicators when studying organic farming, but also to analyze and describe economic parameters. From 1997-2002, an organic arable farming system (Bio) was compared with two Integrated farming systems (IP intensive and IP extensive) on 6 plots in a 6-year crop rotation at Burgrain near Lucerne, Switzerland. The 6 plots were subdivided into 3 subplots of 0.65 ha each. In the organic system, the input of fertilizer and pesticides was substantially reduced, which resulted in a yield reduction of 19% over all 4 arable crops and of 14% if the temporary lays are included. Nevertheless, the organic system showed an excellent net profit, mainly due to the higher prices paid to the farmers for... |

| Laufkäfer, Kurzflügler und Spinnen gehören zu den nützlichen Bewohnern der Feldfauna. Auf dem Betrieb Burgrain wurde in drei Anbausystemen integrierte Produktion (IP) intensiv, IP extensiv und biologisch von 1997 bis 2002 das Vorkommen dieser räuberischen Arthropoden mit Bodenfallen untersucht. Die Laufkäfer traten in den drei beprobten Kulturen Sommergerste, Winterweizen und Körnermais etwa gleich häufig auf. Bei biologischer Bewirtschaftung wurden in Sommergerste und Winterweizen gesichert höhere Aktivitätsdichten als bei den zwei IP-Anbausystemen festgestellt. Im Durchschnitt der drei Ackerkulturen wurden bei Bio 22 % und bei IPextensiv 8 % mehr Laufkäfer gefangen als bei IPintensiv. Es scheint, dass vor allem der höhere Unkrautbesatz bei Bio und... |

| The report presents the current (2005) status of organic farming resarch in Switzerland. Switzerland has a long history of organic farming research, which in its beginnings has been carried out by organic farming pioneers and by private institutions like the Goetheanum, Möschberg Centre and the Research Institute of Organic Agriculture (FiBL). It was in the 1990s, when Swiss Federal Agricultural Research Stations (Agroscope) became also involved in organic research topics. It can be estimated that currently approximately € 7.5 million per annum are allocated very specifically to organic farming research from public budgets. The National Research Programme is organised according to a four-year research concept of the Swiss Federal Office of... |

| Der grosse Spardruck zwingt die Agrarforschungsinstitutionen weltweit, haushälterisch mit ihren Mitteln umzugehen. Die Forschungsschwerpunkte werden deshalb vor allem auf Themengebiete und Versuchsanstellungen gesetzt, in denen Resultate kurzfristig erwartet werden können und welche keine teuren Feldversuche benötigen. Ein Hauptziel moderner agrarwissenschaftlicher Forschung ist jedoch die Entwicklung nachhaltiger Produktionssysteme, die sich nur bedingt in kurzfristig angelegten Versuchen abklären lässt. Die Sicherung einer ausreichenden Nahrungsmittelerzeugung von hoher Qualität, ein haushälterischer Umgang mit nicht erneuerbaren Ressourcen (Düngemittel, Energie) sowie die Erhaltung der Bodenfruchtbarkeit und einer hohen Biodiversität sind wichtige... |

| The DOK-long term trial - unique in his conception - compares the consequences of bio-dynamic, bio-organic and conventional farming systems in a randomised plot trial. The field trial was started in 1978. In the beginning the main goals were agronomic: yield and product quality. In the last decade, therefor research has focused on processes in the soil and the long-term effects of organic farming practice on the environment.The database of agronomic results of more than twenty years has stimulatad the discussion about farming systems and has contributed significantly to the general acceptance of organic farming. |
