    Get PDF
    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 choice of legume and gras species and varietes, the management of swards and their role for fertility building

    Effect of calcified seaweed application on grazing preference by dairy cows

    Get PDF
    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

    Nachhaltige Tiergesundheit und Lebensmittelsicherheit im ökologischen Landbau – Bericht vom ersten Workshop des SAFO-Netzwerks

    Get PDF
    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 VeterinĂ€rmedizin angesprochen. Das Thema des ersten der fĂŒnf Workshops im September 2003 war: „Sozioökonomische Aspekte der Tiergesundheit und Lebensmittelsicherheit im biologischen Landbau“. Ein Ziel des Gremiums ist es Empfehlungen fĂŒr die Weiterentwicklung der EU-Verordnung zur ökologischen Tierhaltung abzugeben. Eine eigens dafĂŒr eingerichtete Arbeitsgruppe kam zu dem Schluss, möglichst viele Interessengruppen in diesen Prozess einzubeziehen. Im Rahmen einer Umfrage sollen sich Vertreter der Interessengruppen zum Einfluss der heutigen Richtlinien auf die Tiergesundheit und Lebensmittelsicherheit im biologischen Landbau unter den verschiedenen regionalen Bedingungen der europĂ€ischen LĂ€nder Ă€ussern und VorschlĂ€ge zur Weiterentwicklung der Bio-Richtlinien unterbreiten

    Experiences with designing and managing organic rotation trials

    Get PDF
    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

    Effect of organic crop rotations on long-term development of the weed seedbank

    Get PDF
    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 effectiveness of weed control operations, and higher populations of ground-living arthropods, may be affecting the Woodside seedbanks

    A Critical Review of Emerging Pedagogical Perspectives on Mobile Learning

    Get PDF
    In recent years, a significant level of interest has developed in the potential of mobile devices such as tablets and smartphones for learning. Mobile learning is an approach that aims to exploit the particular features and characteristics of portable, personal computational devices for pedagogical purposes. This chapter outlines a critique of some current thinking about mobile learning as a contribution to an “appropriate theory of education for the mobile age”: “We are in an age of personal and technical mobility, where mobile devices, 
 are carried everywhere. We have the opportunity to design learning differently: linking people in real and virtual worlds, creating learning communities between people on the move, providing expertise on demand, and supporting a lifetime of learning. In order to understand how people learn through a mobile, pervasive and lifelong interaction with technology, we need to understand the implications of learning with mobile technology and build an appropriate theory of education for the mobile age.” (Sharples. et al 2009) This critical review of the literature analyses some of the pedagogical claims underlying mobile learning and argues that expectations are not based on robust foundations of theory or experiment. Mobile educational technology and associated mobile learning practices are a dynamic domain of constant change, enlivened by developments of new devices, services and software and, alongside possible benefits, streams of significant social and educational dilemmas. This is the challenge for mobile learning and the aim to describe and develop sustainable, well-integrated pedagogical practices and theoretical foundations that exploit the potential of mobile technology for educational goals. The peer-reviewed literature included in this chapter covers the period up to 2017 and is rich with ‘proof-of-concept’ educational activities that demonstrate aspects of practical viability but do not yet provide a foundation on which to build a systemic pedagogy because there is little evidence of systematic benefits or repeatable outcomes, either positive or negative, for the educational role of mobile educational technology. For this chapter peer-reviewed articles were selectively retrieved using broad keywords: ‘mobile learning’; ‘m-learning’; ‘education’; and ‘pedagogy’. Keywords: mobile learning; research review; pedagogy; educational technology

    Diversity of organic livestock systems in Europe

    Get PDF
    There is significant diversity in livestock production across Europe, as a consequence of a range of climatic, historic and economic factors. Yet there are common standards and goals. Enlargement of the European Union has added emphasis to the importance of this diversity. Statistics representing the recent development of organic farming illustrates the considerable variation across the continent in relation to land use and the main animal species farmed. This paper examines some of the climatic and historical impacts of a diverse Europe and recom-mends a degree of flexibility in the adoption of or-ganic standards
