| The objective of the studywas to examine the effect of dried and ensiled sainfoin (Onobrychis viciifolia) on established populations of Haemonchus contortus (abomasum) and Cooperia curticei (small intestine) in lambs under controlled conditions. Twenty-four parasite naı¨ve lambs were inoculated with a single dose of infective larvae of these parasites 28 days prior to the start of the feeding experiment. Twenty-four days post-infection, 4 days prior to the start of the feeding experiment, animals were allocated to four groups according to egg excretion, liveweight and sex. GroupsAandBreceived sainfoin hay and control hay, respectively, for 16 days. Groups CandDwere fed on sainfoin silage or control silage for the same period. Feeds were offered ad... |

| High prices are often reported as an obstacle that inhibits the purchase of organic food products. The aim of this paper is to investigate how organic food products perform at different price levels and whether high prices are an advantage or a disadvantage for consumers’ repeat purchase of organic food. Based on analyses of actual purchase data, this study explores the effect of two product attributes (production method and price) on repeat purchase. The analysis is based on purchase data for four product categories (red meat, chicken, milk and hard cheese) registered by the GfK panel in 2011 in Denmark. The results show that within product categories, repeat purchase is linked more to production method than to price, and it is more prevalent for organic... |

| Um eine hohe Backqualität vor allem auch für Weißmehlprodukte zu erreichen, muss der Weizen optimal mit Nährstoffen versorgt werden. Dies bedeutet im ökologischen Landbau, dass das N-Angebot erhöht werden muss. Während dies einerseits Erträge und/oder Qualität steigern kann, erhöht es andererseits auch die Anfälligkeit des Bestandes vor allem gegenüber obligaten Pathogenen, wie Rost und Mehltau. Außerdem nimmt der Fusariumbefall bei erhöhtem N-Angebot deutlich zu. Fusariumbefall beeinflusst die Qualität durch die Produktion von Mykotoxinen sowie durch eine unmittelbare Verminderung der Backqualität. |

| Im seit 1994 laufenden Projekt Ökologische Bodenbewirtschaftung zeigt sich, dass die Bodenbelebung und -stabilisierung mit intensiver Durchwurzelung im ökologischen Ackerbau relativ schnell verbessert werden kann. Allerdings sind bei konsequent nichtwendender Bearbeitung keine Höchsterträge zu erzielen. Abschnitte: - Pflug ja oder nein? - Standörtliche Variabilität - Nichtwendend – niedrigere Erträge - Bodenchemie – keine großen Veränderungen - Reduzierte Bearbeitung – höhere Humusgehalte - Mehr und aktivere Bodenmikroben - Bodenschonende Bearbeitung – mehr Regenwürmer - Schlussfolgerungen für die Praxis Tabellen und Abbildungen: Abb. 1: Im PÖB verwendete Grundbodenbearbeitungssysteme Abb. 2: Hektarerträge von Gerste und Winterweizen,... |

| Organic agriculture can and should play an important role in solving future challenges in producing food. The low level of external inputs combined with knowledge on sustainablity minimizes environmental contamination and can help to produce more food for more people without negatively impacting our environment. Organic agriculture not only includes farming as a production practice but it also includes processing, trade and consumption. Nevertheless, Organic agriculture must always evolve to overcome emerging challenges. Science-based knowledge attained through dedicated research is required to strengthen organic food and farming as a means to solve future challenges. In 2010, a global discussion about Organic 3.0 was initiated to address current problems... |

| When an automatic milking system (AMS) is introduced on a farm the milking of cows and related work is changed in many ways compared to farms with traditional milking systems. The objective of this paper was to study the effect of the introduction of robotic milking in Finland on the composition and hygienic quality of milk. The study was carried out on three farms which were the first in Finland to introduce the automatic milking system (Volontary Milking System™). Main chemical composition, somatic cell count, total bacteria count, freezing point, free fatty acids, as well as Bacillus cereus, Clostridium spores, psychrotrophic bacteria and coliforms were determined. After the introduction of the automatic milking system an increase in somatic cell count... |

| Zwischenfrüchte spielen in ökologischen Anbausystemen mit reduzierter Bodenbearbeitung eine wesentliche Rolle. In dieser Übersichtsarbeit werden Ergebnisse aus einer ausführlichen Literaturrecherche hinsichtlich des N-Lieferungs- und Beikrautunterdrückungspotenzials von Zwischenfrüchten dargestellt. Die N-Aufnahme- und Biomasseertragsdaten verschiedener Zwischenfruchtarten und -artenmischungen werden tabellarisch wiedergegeben. Sie unterliegen – auch innerhalb einer Art – einer großen Spannbreite. Die N-Aufnahme ist dabei weitgehend – auch artübergreifend – vom Biomasseertrag abhängig. Gründe für ein gutes N-Aufnahmevermögen werden diskutiert. Die Steuerung der Mineralisierung durch die Wahl des Einarbeitungszeitpunkts wird erörtert. Mechanismen der... |

| Ein zentrales Problem im ökologischen Pflanzenbau ist es, die Schwierigkeiten bei der Regulierung der Unkrautflora in den Griff zu bekommen. Neben den direkten Verfahren der Unkrautregulierung (biologische, thermische oder mechanische Maßnahmen), kommen im ökologischen Landbau vor allem indirekten Maßnahmen eine besondere Bedeutung zu. Neben der Fruchtfolge sind weitere indirekte Unkrautregulierungsmaßnahmen, wie Lichtentzug, Saatgutreinigung, Saatgutqualität, Bodenbearbeitung, Standraum der Kulturpflanzen und Sorteneigenschaften zu nennen. |

| Background: This study investigated the extent of traditional knowledge and use of homemade herbal remedies for livestock by farmers in 3 Swiss cantons (Aargau, Zurich, Schaffhausen). The study focused on organic farms. Methods: At 21 farms, 24 farmers aged 36–83 years were interviewed with a semi-structured, detailed questionnaire. For each homemade herbal remedy, the plant species, mode of preparation, source of knowledge, and application were gathered. Satisfaction of the farmers with the application was estimated with the aid of a visual analogue scale. Results: Information on a total of 165 homemade remedies was collected of which 123 contained a single plant species only (homemade mono-species herbal remedies, HMHR). The 123 HMHR were selected for... |

| Este trabalho resgata o significado do termo desenvolvimento sustentável e salienta as diferentes ideologias implícitas em duas correntes de pensamento, a ecotecnocrática e a ecossocial. A partir da análise destes enfoques de desenvolvimento, observa-se a insustentabilidade da agricultura convencional e destacam-se os princípios da Agroecologia no processo de construção de estilos de agricultura sustentável. Nessa perspectiva, aborda-se a utilização de sistemas agroflorestais como estratégia para a promoção do desenvolvimento rural sustentável. Com base na revisão bibliográfica são analisados três projetos de sistemas agroflorestais na agricultura familiar em distintos biomas brasileiros. Conclui-se que estes projetos possuem características que podem ser... |

| Organic farming in Turkey is experiencing a strong growth in recent years, with a particular attention to export towards Europe. International and domestic trade opportunities require an efficient control system for organic products. In this paper we analyse the data from inspections of two European control bodies in Turkish farms to analyse risk patterns of non-compliance with the organic regulation. A proportion test is performed to identify the types of crops that are more likely related to non-compliant operators. |
