Life Cycle Assessment (LCA) is a method that can be used to assess the environmental impact of agriculture, but impact categories and the functional unit of classical LCA’s must be adapted to the specific agricultural production process. Serving as an example, the framework of a LCA of 18 grassland dairy farms covering three farming intensity levels and carried out in the Allgäu region in southern Germany is presented. By focussing on the chosen impact categories and the respective, suitable functional units, the specific needs and backgrounds of conducting an agricultural LCA are discussed in general. aus: Haas, G. und Wetterich, F. und Geier, U.

Earthworms are key organisms and indicators of soil quality, which also links to the productivity of an ecosystem. The higher the earthworm density and diversity, the better the earthworm’s living conditions and the more fertile is the soil. They are relatively easy to detect and determine into three ecological groups. The number and distribution of the three ecological categories and the numerous earthworm species depends on soil management, soil type, the Vegetation and climate conditions. In this technical note, various methods how to sample, measure and interpret earthworms are shown. |

Bei heterogenen Bodenverhältnissen - die für eine Vielzahl von Regionen und Landschaften charakteristisch sind - entscheidet primär die Auswahl der Versuchsfläche über die erfolgreiche Durchführung von Feldversuchen. Der Auenboden des Untersuchungsstandortes - Versuchsbetrieb für Organischen Landbau "Wiesengut", Hennef nahe Bonn - weist kleinräumig teilweise innerhalb weniger Meter wechselnde Bodenverhältnisse auf und schränkt damit die Durchführung von pflanzenbaulichen Feldversuchen ein. Für die gezielte Auswahl geeigneter Feldversuchsflächen wurde ein Kriterienkatalog erarbeitet, der folgende Datenbereiche umfaßt: Tachymetrische Vermessung - Kartenwerk der bodenbedingten Bestandesunterschiede; Multitemporale und multispektrale Luftbildaufnahmen;... |

The total ash content is usually considered to be fairly constant during the composting period, apart from addition of minerals by precipitation and losses by seepage. However, our field trials with farmyard manure have shown that the ash fraction insoluble in hydrochloric acid increased much more than the soluble fraction in the same time. If changes are merely caused by composting intensity (e.g. organic matter degradation), both fractions should be accumulated in the same degree. It is hypothesized that the higher rise of the HCl-insoluble fraction indicates a higher amount of soil material in the heaps at the end compared to the beginning of composting, as the insoluble fraction originates mainly in soil-borne silicates while the soluble fraction is... |

The aim of the present study was to examine decomposition of plant material (maize straw, green and rooibos tea) in stratified soils of the long-term tillage experiment, established in 1999 and shifted from conventional to organic farming system in 2015. The plowing in conventional tillage (CT) has been done by moldboard plow 20 cm deep, while in minimum tillage (MT), soil disturbance has been up to 10 cm deep by a Special disc harrow. More than 15 years of long term Minimum tillage, with reduced soil disturbances and improved residue management, resulted in stratification of soil organic carbon and nutrients with highest concentrations in the very topsoil. |

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... |

Workshop presentation with particular focus on values, transferability and praxis relevance of organic farming research. Examples from agricultural engineering lead to the conclusion, that prototype farming, goal oriented project management, participative decision making and funding, coaching of co-operation, and coaching of conflict management may enhance long term, holistic and interdisciplinary research. |

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... |

The aim of this handbook of experimental guidelines is to help conduct experiments for organic horticulture in greenhouses throughout Europe. It considers vegetables, fruit and ornamental production. Using standardised research procedures for experiments will aid a comparison of results and dissemination of knowledge. The editors have tried to incorporate as many climatic zones, countries and crops as possible in order to represent a wide area of Europe although some smaller crops or certain specific climates could not be included. |

Haltung mit Zugang zu Grünausläufen für Legehennen nimmt in Deutschland zu. Ziel des Beitrags ist eine Übersicht über Methoden zur Quantifizierung von Nahrungsangebot bzw. -aufnahme pflanzlicher und tierischer Komponenten, welche in dreijährigen Untersuchungen mit Mobilställen angewendet wurden zu geben. Verhaltensbeobachtungen erbrachten, dass im Mittel 50 - 70 % der Hennen im Auslauf waren, vor allem mit Nahrungssuche beschäftigt. Ein hoher Verbrauch an pflanzlicher Biomasse wurde kalkuliert (260 g Frischmasse/Tag). Die Vegetationsveränderungen während der Beweidungsphasen zeigten Vorlieben für bestimmte Pflanzenarten. Dies ergaben auch Analysen von Phytolyten oder Alkanen im Kot der Tiere. Das Angebot tierischer Komponenten wurde mit verschiedenen... |

Yield differences and trends, organic matter accumulation, and the loss of nutrients to deeper soil horizons are discussed using data from organic and conventional maize/tomato cropping systems from the Long Term Research on Agricultural Systems Project (LTRAS) at the University of California, Davis. Compared to the conventional system, higher and increasing yields of tomatoes were observed in organic systems, but lower yields of maize. Fruit quality, measured as soluble solids, was not significantly different. Soil organic matter increased in the organic system, but remained stable in the conventional one. More irrigation water was used in the organic system than in the conventional one due to higher rates of infiltration, but less winter runoff... |

This paper aims to explore farmers' conditions, strategies and performances in a context of multi-dimensional policy requirements, market imperfections and globalisation. The basic assumption sees conditions as drivers for farmers’ strategies that then result in performances of the sector. The methodological approach is based on the Conditions-Strategies-Performances (CSP) model which is used for the analysis of three case studies. The model helps to identify changes in framework conditions over time, resources among relevant groups of primary producers, adaptation strategies and finally, to explore the related social, economic and environmental effects. The analysis is based on three case studies, three farmers’ groups in Germany and Sweden. Results show... |
