| A crop rotation experiment was established in 1996/97 at three locations representing different soil types and climates. Three factors were tested: i) crop rotation with different proportions of N2-fixing crops, ii) with and without a catch crop, and iii) with and without animal manure. A green manure crop increased yields in the following cereal crops, but at the rotational level, total yields were larger in crop rotations without a green manure crop. There were positive effects of animal manure and catch crops on yield. However, except for the coarse sandy soil, the yield effects of catch crops and animal manure decreased over time when a grass-clover green manure was included in the rotation. It appeared that the buffering effect of clover can... |

| [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. |

| Ein besseres Verständnis der Dynamik hinter der Freisetzung von pflanzenverfügbaren Nährstoffen aus Boden oder organischen Dünger und eine Verbesserung der Nährstoffverwertung von Ackerfrüchten sind zwei wichtige Herausforderungen, um die Produktivität im ökologischem Ackerbau zu erhöhen. Doch diese Prozesse sind stark sowohl von biotischen (z.B. Bodenmikroben) als auch abiotischen (z.B. Temperatur, Niederschlag, Bodenfeuchtigkeit, Bodenstruktur) Faktoren beeinflusst und erschweren effiziente Untersuchungen. Fernbilderkundung-Technologien (remote sensing) haben sich in den letzten Jahren stark weiterentwickelt und bieten heute neue Ansätze und Methoden, um der Ernährungsstatus von Pflanzen sowie die Dynamik des Pflanzenwachstums nicht destruktiv zu... |

| We found clear correlations between management measures, tree characteristics and fruit characteristics. This means that growers can regulate apple quality during the growing season. On the basis of the two apple experiments, we can distinguish respective sets of growth and differentiation parameters and evaluate them in the light of conventional fruit cultivation science. Our results have little new value for fruit growing in practice, however. The value of our research lies in the approach developed to draw up a quality concept and the way in which we can apply this concept to crops about which little knowledge exists regarding the relationship between management measures, crop characteristics and product quality characteristics. Our research also offers... |

| 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... |

| In long-term organic crop rotation experiments for cereal production, stubble cultivation to control perennial weeds increased nitrogen leaching compared to catch crops grown after harvest. Stubble cultivation contributed to the control of Elymus repens on a sandy soil, but not to the control of Cirsium arvense on a loamy soil. Manure application had a tendency to decrease E. repens density in one rotation at the sandy soil. Grass-clover green manure decreased C. arvense in the succeeding crops. Despite high infestations of perennial weeds, yields were at the same level with as without stubble cultivation. The results point to an important dilemma in organic farming: should the farmer control perennial weeds in the stubble at the expense of losing nitrogen... |

| 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... |

| Die biologisch-dynamische Forschertagung 2001 fand vom 16.- 20. Juni auf Skillebyholm statt. 32 Forscher aus Dänemark, Deutschland, Holland, Neuseeland, Österreich, Schweden und der Schweiz waren anwesend. Das Tagungsthema war “der Mensch wird zur Grundlage gemacht” (Textstelle aus dem 4. Vortrag des Landwirtschaftlichen Kurses) und der Vortrag “der unsichtbare Mensch in uns” von R. Steiner (1923 Vortrag vom 11.2.1923, GA221) wurde gelesen und besprochen. Vorträge über Krankheitsbehandlungen bei Pflanzen und Tieren wurden gehalten und Übereinstimmungen zum Menschen wurden diskutiert. Während man zwischen Mensch und Pflanze Übereinstimmungen aufzeigen konnte, war dies zwischen Mensch und Tier nicht möglich. Neues aus der Qualitätsforschung wurde... |

| 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... |

| In der vorliegenden Arbeit wird der Vorschlag gemacht, das Bodengefüge aufgrund seiner nach aktuellem Forschungsstand bekannten, vielfältigen Verknüpfung mit der Lebensraum-, Regelungs-, und Produktionsfunktion als geeigneten Indikator für die ökologische Funktionsfähigkeit des Bodens heranzuziehen. Mit der Erweiterten Spatendiagnose nach HAMPL/KUSSEL (ESD) wird eine aus der GÖRBING-Spatendiagnose entwickelte, einfache, wissenschaftlich besser auswertbare Version der Gefügezustandsbeurteilung mit dem Spaten vorgestellt, die den Empfehlungen der ISCO (Internationale Gesellschaft für Bodenschutz) in Bezug auf leichte Vermittelbarkeit und geringen technischen Aufwand sehr nahe kommt. Das Forschungsziel der Arbeit ist es, die Aussagekraft der in der ESD zur... |

| 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... |

| A prerequisite for good research is the use of appropriate methodology. In order to aggregate sound research methodology, this paper presents some tentative guidelines for physical weed control research in general, and flame weeding, weed harrowing and intra-row cultivation in particular. Issues include the adjustment and use of mechanical weeders and other equipment, the recording of impact factors that affect weeding performance, methods to assess effectiveness, the layout of treatment plots, and the conceptual models underlying the experimental designs (e.g. factorial comparison, dose response). First of all, the research aims need to be clearly defined, an appropriate experimental design produced and statistical methods chosen accordingly. Suggestions... |

| 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... |
