| O objetivo desta pesquisa foi avaliar o efeito in vivo de diferentes concentrações de óleo de citronela no controle do carrapato bovino. Foram utilizadas 20 vacas da raça Holandês, distribuídas em quatro grupos de cinco animais cada um. Os tratamentos foram constituídos pelo controle negativo, amitraz a 0,025%, óleo de citronela a 3 e 4%. Para avaliação, foram contadas fêmeas ingurgitadas de carrapato antes (média dos dias -3, -2, -1) e após a aplicação dos produtos nos dias 3; 7 e 14. A média de eficácia no controle do carrapato foi de 93,8; 22,5 e 39,1% para o amitraz e óleo de citronela a 3 e 4%, respectivamente. O uso de diferentes concentrações de óleo de citronela apresenta controle parcial do carrapato. |

| 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... |

| 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. |

| In der ökologischen Schweinemast bestimmt das Vermarktungsziel die Auswahl der Genetik und Fütterungsintensität. Eine vornehmlich schlachtkörperqualitäts-orientierte Vermarktung, d. h. die Ausrichtung auf Fleischertrag, verlangt moderne Genotypen mit hoher körpereigener Proteinsynthesekapazität (also z. B. eher geringe Duroc-Genanteile im Masttier) und Rationen, die eine qualitativ hochwertige Aminosäurenversorgung gewährleisten, was zu einem mehr oder weniger hohen Nährstoffimport von außen in das landwirtschaftliche System hinein führt (high external input system). Fleischqualitäts-orientierte Vermarktungsziele tolerieren Genotypen mit niedrigerer körpereigener Proteinsynthesekapazität bzw. Rationen mit geringwertigerem Aminosäurenprofil bis hin zu... |

| Ingen edderkopper er skadedyr i jordbrukssammenheng, alle er rovdyr og spiser insekter og edderkoppdyr av ulike slag. Det var store forskjeller i mengde og antall arter av edderkopper i et økologisk og et konvensjonelt jordbærfelt på Sunnmøre sommeren 2002. Det viste seg å være klart flere arter, og dessuten flere voksne og flere unge (juvenile) edderkopper i det økologiske jordbærfeltet enn i det konvensjonelle. Dette kom tydeligst frem på våren og forsommeren, når dyrene er mest aktive. Det ble funnet 411 edderkopper (herav 219 juvenile) i det økologiske feltet, men bare 40 i det konvensjonelle (herav 12 juvenile). 13 arter ble funnet i det økologiske og 6 i det konvensjonelle feltet. De viktigste artene var ulike ulveedderkopper (Lycosidae) som Pardosa... |

| The use of medicinal plants and other natural multicomponent remedies might be one measure to reduce the use of antibiotics in livestock. Ethnoveterinary research has the potential to identify promising natural remedies. The knowledge about remedies for livestock was collected from farmers in six central Swiss cantons, Glarus, Obwalden, Nidwalden, Schwyz, Zug and Uri. Between February and April 2013 49 interviews with 63 farmers (25 females and 38 males, aged 24–74) were conducted. We collected information on the manufacturing of 370 homemade remedies. Of these, 114 contained no plants, 26 contained a mixture of two to five plants, and 230 contained one plant species (defined as homemade single-herbal remedy report (HSHR)). These 230 HSHRs represented 68... |

| Comprehensive information on B vitamin contents in cereals and grain legumes used for animal feeding is scarce. Thus, the objective of this study was to determine the contents of thiamine and riboflavin uniformly in a selection of cereals and grain legumes. Additionally, the evaluation of varietal and environmental effects on the amounts of both B vitamins was targeted. We analysed contents of thiamine and riboflavin with HPLC in 855 samples of different organically cultivated cereal and grain legume cultivars. Since the sample set was unbalanced, it had to be adapted for further statistical analyses. Data of 541 samples of ten cereal and grain legume cultivars was used to assess the influence of variety and environment with generalized linear models.... |

| Consumption of animal-source food is criticised, among other reasons, for its relatively high environmental impact. It is, however, increasingly acknowledged that livestock can contribute to nutrition security if they upcycle low-opportunity-cost feed (LCF) – food waste, food processing by-products and grass resources – into nutritious animal-source food. So far, however, no study explored the allocation question “to which livestock should we feed what LCF to maximise livestock's contribution to human nutrition”. Here we optimise the use of the LCF available in the EU, using a model that assigns LCF to those livestock systems that maximise animal protein production. We included the five most common livestock systems in the EU – pigs, laying hens, broilers,... |

| Farmers are important actors for regional development and biodiversity protection. Agri-environment-climate measures (AECM) are therefore a central tool of the European Union to support its biodiversity conservation policy. AECM generally reward farmers for fulfilling predefined management actions or avoiding specific practices. In contrast, result oriented AECM are intended to reward farmers for the outcome of nature friendly management practices. This approach gives more flexibility in management and hence promotes farmers engagement and autonomy. Besides educational activities and agricultural advisory services farmers need user friendly tools to assess biodiversity in order to meet result oriented AECM. Thus, we present a biodiversity assessment scheme... |

| Orchard floor management impacts soil conditions and thus tree performance. This research was initiated to investigate the effects of alternative orchard floor management systems compatible with organic production on soil parameters using the“Pacific Gala” apple cultivar (Malus × domestica Borkh.) on three rootstocks of varying vigor. Alfalfa hay mulch, propane flame burner, and Swiss sandwich system(combination of resident vegetation and tilled strips)were compared from 2001 to 2005. These treatments were applied to tree rows which provided different vegetation-free areas. Contrasting additions of organic matter were evaluated for their effect on soil organic matter (SOM), C content, nitrate and ammonium availability, moisture, and soil food web through... |

| One core idea behind organic production is that cropping systems should be less dependent on resource import than conventional production and minimize negative environmental effects. This study aimed to test novel organic rotations, designed to reduce reliance on external resource import. We compared a conventional system (C) and an organic system relying on manure import (O1) to two rotations (O2 and O3), both relying on autumn cover crops for soil fertility, and in O3 green manure rows were left as intercrops. Resource import differed between 149, 85, 25 and 25 kg N ha-1 year-1 in C, O1, O2 and O3. Crop yields were lower in the organic systems (on average 82% of conventional yields), differing among crops, when based on the area grown with main crops.... |

| (1) Rückstände im Biowein! Ein Mediensturm im Bioweinglas wühlte im vergangenem Herbst die Schweiz auf, nachdem Spuren von Pestiziden nachgewiesen worden waren. Wie kommen die Spuren in den Biowein? Und wie hält man sie fern? "bio aktuell" informiert in einer dreiteiligen Artikelserie. Die Abdrift aus Nachbars Weinberg dürfte für Pestizidspuren im Biowein mitverantwortlich sein. Auch andere Kulturen haben mit diesem Problem zu kämpfen. Gerichtlich Abhilfe ist zwar möglich. Doch ein Jurist rät, es vorher auf die sanfte Tour zu versuchen. (2) Wenn auch noch einiges unklar bleibt, so viel ist sicher: Eine sorgfältige Weinbereitung, die IP und bio sauber trennt, kann entscheidend dazu beitragen, Bioweine frei zu halten von Pestizidrückständen.
