| In the analysis, we will - identify the most significant changes over time in relevant market, regulatory, institutional and territorial conditions, - assess the social, economic and other resources available among different groups of primary producers, - relate conditions and resources to the (adaptation) strategies pursued (e.g. regarding the management of the chain and risks), and - explore the (potential) impacts of the resulting (or expected) changes on social, economic and environmental performances. The analysis aims at capturing the interrelationships between external and internal conditions, (adaptation) strategies and (sustainability) performance. A first important step in the analysis is to express conditions, strategies and... |

| Both deleterious (pathogenic) and beneficial (mycorrhizal) fungi inhabit plant roots with strong impact on plant growth and health. Various methods have been used to quantify these fungi, such as indirect measurements of plant parameters, disease index, staining techniques and serological/genetic/biochemical markers. The objective of this work is to evaluate the possibility of using signature fatty acids to quantify root-inhabiting fungi in planta and in soil. Different fatty acid-based methods can be used to quantify fungi. Phospholid fatty acids (PLFA) can be used for biomass estimation and neutral lipid fatty acids (NLFA) for estimation of fungal energy reserves and the NLFA/PLFA ratio can give information on the physiological status of the fungus. It... |

| Rund 30 ForscherInnen aus Deutschland, England, Holland, Schweden und der Schweiz trafen sich dieses Jahr zur internationalen biologisch-dynamischen Forschertagung auf dem "Gut Rheinau". Während der Tagung stand zum Einen der Begriff der biologisch-dynamischen Forschung im Vordergrund. So wurde in Vorträgen heraus gearbeitet, was das Charakteristische an der biologisch-dynamischen Forschung ist, welche Motivationen dazu führen, biologisch-dynamische Forschung zu betreiben und welche Seelenhaltungen man bei der Forschung einnehmen kann. Ein weiterer Vortrag ging der Frage nach in wie weit man mit naturwissenschaftliche Forschung zur Objektivität gelangen kann. Auch wurde darüber diskutiert wie sich Naturwissenschaft und Geisteswissenschaft ergänzen und... |

| Im Vorgängerprojekt "Strategien zur Regulierung von Wurzelunkräutern im Ökologischen Landbau" (02OE055/1) wurde 2002 und 2003 u.a. die Effektivität der maschinellen Ampferregulierung mit dem Gerät WUZI, das Ampferstechen durch Hand sowie das Abflammen im Vergleich zu unbehandelten Kontrollparzellen (jeweils in Kleinparzellen-Versuchen) auf dem Versuchsbetrieb Trenthorst des Instituts für ökologischen Landbau (FAL) untersucht. Dabei zeigte sich ein sehr guter Erfolg der Ampferbekämpfung durch den Einsatz des maschinellen Ampferstechens mittels WUZI, eines Prototypen, der von einem österreichischen Landwirt entwickelt und als Selbstfahrer konstruiert wurde. Die Ampferpflanzen werden mittels WUZI angesteuert und mit einem Bohr-Fräskopf, der in den Boden... |

| Circadian rhythms established by the endogenous clocks enable organisms to anticipate periodic and cyclic changes in their environment. This internal time-keeping system is highly conserved amongst animals and provides them with adaptive advantages as biological processes can be scheduled to occur at the most crucial times of the day. Circadian rhythm is emerging as an important regulator of immune functions. However, there is a paucity of information on the influence of this biological phenomenon in the immune mechanisms of teleost fish. A series of studies was conducted to investigate the circadian rhythms of systemic and mucosal innate immunity using model (i.e., zebrafish, Danio rerio) and non-model (i.e., permit, Trachinotus falcatus; rainbow trout,... |

| Soil organic matter (SOM) fraction characteristics need to be developed as indicies that can be related to specific soil functions. The general effects of organic management on prominsing indicies of SOM status (POM and a rapid measure of base hydrolyzable N) were determined by comparing the characteristics of organic and conventionally managed soils obtained from nine long-term trials in North America. In addition, a more detailed study was conducted of POM and of hydrolyzable N fractions (including amino-acids, amino sugars) at a site where use of organic practices failed to increase SOM. In the multi-site comparrison, legume- and manure-based organic systems performed equally well in their ability to increase the quantity of SOM as well as enrich the... |

| Nach Ansicht der Autoren sollen und können Versuche im eigenen Betrieb nicht wissenschaftliche Untersuchungen an Forschungseinrichtungen ersetzen. Vielmehr stellen sie eine sinnvolle Ergänzung zur Forschung an solchen Institutionen dar. Durch ein optimales Zusammenspiel beider Formen könnten so in Zukunft dem Landwirt die Informationen an die Hand gegeben werden, die er für seine erfolgreiche Betriebsführung braucht. Dieser Leitfaden für Praxisversuche deckt Experimente zur pflanzlichen Erzeugung ab. Unberührt davon lassen sich jedoch auch Versuche zur Tierhaltung, im Vermarktungsbereich oder zur Betriebswirtschaft im eigenen Betrieb durchführen. Der vorliegende Leitfaden gibt grundlegende und nützliche Informationen darüber, wie ein nicht... |

| 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... |

| [Einleitung:] Die Biologisch-Dynamische Wirtschaftsweise ist die älteste unter den verschiedenen Methoden des Ökologischen Landbaus. Ihr geistiges Fundament ist eine Reihe von Vorträgen, die Rudolf Steiner (1861-1925) im Jahr 1924 in Koberwitz bei Breslau für Landwirte hielt (STEINER 1924a). Daher können ihre Voraussetzungen und Intentionen und auch ihr Forschungsansatz nicht losgelöst von dem spirituellen Weltbild der Anthroposophie, deren Begründer Rudolf Steiner ist, betrachtet werden. Auf einige Motive und Aspekte dieser Herangehensweise an wissenschaftliche Fragestellungen soll hier kurz eingegangen werden. |

| A long term field monitoring concerning the development of Organic Farming is performed at the bio-farm “Rutzendorf “ of the BVW GmbH in the Marchfeld region east of Vienna. It is an interdisciplinary project of eleven research institutes, which started in 2003. The aims of the project are: examination of changes concerning soil and plant parameters accompanying the conversion to organic farming; investigation of the effects of different organic fertilisation systems (green manure, communal green forage compost, farmyard manure) on soil properties and on crop performances; analysis of existing biotopes (hedges and field stripes) on the farm, and planning and selective realization of new biotopes with the aim of enhancing the biodiversity of the area,... |

| The C and N dynamics in perennial grass-clover mixtures are not fully understood although such mixtures dominate temperate grassland. The co-existence of clover and grass involves both competition for and transfer of nutrients between the species. The nutrients may originate from leaky root systems, from a rapid turnover of the fine root systems, or from degradation of more stabile organic material. The aim of the study is - to determine the origin of DOC and DON in grass-clover mixtures - to determine the composition of DOC and DON from the species - to investigate the transfer of C and N between grass and clover Method: In a third year grass-clover ley at the KVL research fields, mezotrons were installed to depths of 20, 40 and 60 cm in... |

| The static chamber approach is often used for greenhouse gas (GHG) flux measurements, whereby the flux is deduced from the increase of species concentration after closing the chamber. Since this increase changes diffusion gradients between chamber air and soil air, a nonlinear increase is expected. Lateral gas flow and leakages also contribute to non linearity. Several models have been suggested to account for this non linearity, the most recent being the Hutchinson±Mosier regression model (HMR). However, the practical application of these models is challenging because the researcher needs to decide for each flux whether a nonlinear fit is appropriate or exaggerates flux estimates due to measurement artifacts. In the latter case, a flux estimate from the... |
