| Changes in the weed seedbank were monitored between 1991 and 1998 in two experiments that were established to compare organic crop rotations at two sites in NE Scotland. Two rotations, replicated twice at each site, were compared and all courses of both rotations were present every year. There were relatively minor changes in weed species diversity over time, but major changes in seedbank abundance. Weed seed numbers were relatively low in rotations with a high proportion of grass/clover ley. Differences in level of seedbank across the rotation were relatively predictable at Tulloch but much less so at Woodside where factors such as the effect of the grass/clover ley seemed to play a lesser role. Other factors, such as weather and its influence on the... |

| Das EU-Projekt SAFO beschäftigt sich mit nachhaltiger Tiergesundheit und Lebensmittelsicherheit. Im zweiten SAFO-Workshop wurden „Möglichkeiten und Grenzen der Tierhaltungspraxis zur Sicherung von Tiergesundheit, Tierwohl und Lebensmittelsicherheit im biologischen Landbau“ diskutiert. 78 Teilnehmer aus 25 Ländern, darunter Vertreter aus tiermedizinischer und landwirtschaftlicher Forschung und Praxis nahmen am Workshop teil. Er fand vom 25. bis 27. März 2004 an der Fakultät für ökologische Agrarwissenschaften der Universität Kassel in Witzenhausen statt. Das Programm umfasste 25 Vorträge und 2 Arbeitsgruppensitzungen. Die aktuelle Situation und zukünftige Strategien der Tierhaltungspraxis im biologischen Landbau, der Einfluss von Weide und Fütterung auf... |

| This report was presented at the UK Organic Research 2002 Conference. An experiment was carried out to determine whether the application of calcified seaweed improved the preference of organic dairy cows for pasture. Two treatments were applied in May 2001; calcified seaweed applied at 625kg/ha (C+) or no application (C-). The number of cows grazing within individual plots was recorded in July and August 2001. A significantly higher number of cows were recorded in C+ plots than in C- plots. This effect could not be explained by changes in soil or herbage analysis. There may have been additional unknown effects of the C+ treatment on herbage palatability but the results may also have been influenced by external factors such as the location of water troughs. |

| Grass clover leys form the basis of most organic farming systems yet the selection of seed mixtures is often founded on tradition or cost. Based on a review of recent and past research this review provides a wealth of information on grass and legume species and varieties, mixture selection, ley establishment and pasture management. The objective of the Grass Clover Ley research review are: 1. To identify all the relevant research undertaken 2. Collate the results of the research 3. Draw on farm and commercial experience 4. Summarise the practical implications of the research for organic farming 5. Facilitate access to the results of research to advisers in a form which allows easy transfer to farmers. The report presents key conclusions about the... |

| This report was presented at the UK Organic Research 2002 Conference. Practical problems encountered in two long-term organic rotation trials at Aberdeen and Elgin are discussed. Compromises have had to be made in designing and managing the trials: how to include livestock and measure output, plot size, marking and fencing, discards and paths, replication, rotation length, randomisation of crop sequence, site uniformity, manoeuvrability of machines, soil compaction and exposure to pest damage. |

| Das von der EU finanzierte SAFO-Projekt soll in Europa eine positive Entwicklung der Tiergesundheit und Lebensmittelsicherheit in der biologischen Tierhaltung vorantreiben. Aktuelle Forschungsresultate werden von Forschern verschiedener Fachrichtungen vorgestellt und mit Politikern, Landwirten und Konsumenten diskutiert. Aufgrund des Themenschwerpunktes sind insbesondere auch Forscher und Praktiker aus der Veterinärmedizin angesprochen. Das Thema des ersten der fünf Workshops im September 2003 war: „Sozioökonomische Aspekte der Tiergesundheit und Lebensmittelsicherheit im biologischen Landbau“. Ein Ziel des Gremiums ist es Empfehlungen für die Weiterentwicklung der EU-Verordnung zur ökologischen Tierhaltung abzugeben. Eine eigens dafür eingerichtete... |
