| This guide is aimed at farmers who are considering diversification into horticulture. It assumes a sound and system-based understanding of agricultural systems, but limited knowledge of fruit and vegetable production. It gives a general introduction on organic systems and soil fertility components including factors and examples of successful crop rotation. For the main pests and diseases simple and system-based measures are highlighted, as e.g. considering the right timing of control measures, crop rotations and tillage. For weed management weeding machinery is briefly explained. Basic questions on how to choose the right variety and the equipment for weeding, harvest, and storage are discussed. Additionally, the guide gives a rough overview and... |

| Although there is a widespread assumption that organic farming developed in response to the intensification of agriculture in the second half of the twentieth century, a number of scholars have sought to show that the origins of the movement date to the 1920s and 1930s. They argue that that there is continuity in the development of the organic movement and that the ideals and values of the early organicists are the origin of current organic farming discourse. A detailed history of the organic movement indicates however, that a number of social movements converged to contribute to its development. Particular cultural and socio- demographic changes in the last three decades of the twentieth century produced a new ex-urban organic movement with a new organic... |

| 1. Organophosphate (OP) based dips offer a broad spectrum control against all major ectoparasites in the UK. However, there is continuing controversy over the safety to dip operators and the environment. The use of OPs is prohibited by organic standards, primarily because of concerns about mammalian toxicity. 2. Organic farmers are permitted to use synthetic pyrethroids (SPs)(dip products and pour-on products) and/or macrocyclic lactones (injectable products) to treat/control ectoparasites providing a derogation has been obtained from the certifying body. 3. SPs have been shown to be considerably more toxic to aquatic organisms than OPs. The environmental impact of SPs is not limited to levels in dip but also to residues in sheep fleeces. SPs may be... |

| 1. Organic farming is based on principles of co-existence with natural systems, the minimisation of pollution and damage to the environment, and the promotion of the health of soil, plant and animal to produce healthy food with high standards of animal welfare and respect for the wider social and ecological impacts of the agricultural system. 2. Organic Farming has become an important aspect of EU agri-environment policy. Since the implementation of EC Reg. 2078/92 the EU promotes organic farming explicitly on its positive effects on the environment. 3. The environmental and biodiversity benefits of organic systems in the lowlands for mixed farming is generally accepted (Shepherd, 2003) but similar benefits for upland systems have not been identified.... |

| Organic livestock farming has grown in Wales in recent years. It is focused on producing animals from a predominantly forage-based system, with an emphasis on maintaining animal health through improved welfare and a reduction in the use of routine, conventional veterinary treatments. Breeding and feeding are important factors of the health and welfare of farm animals in organic systems. The guidelines of EU regulation (EC) 1804/1999 address the issue of sourcing of (breeding) stock. Moreover, only activities such as the use of genetically modified organisms (GMOs) and embryo transfer are excluded, and few provisions are included that concern breeding. A number of breeds used in conventional farming could be considered as ’high maintenance’ animals... |

| In the UK, in January 2006, the total area of organic and in-conversion land was 619,852 ha. This represents a decrease of 8% compared to January 2005. In Wales, in January 2006, the area of fully organic land increased to 5% of the total area of agricultural land. The number of organic producers and growers, including those in-conversion, increased from 618 in 2003 to 688 in 2006. Organic producers represent approximately 4% of all farmers in Wales. Welsh organic producers represent 16.6% of the UK total number of organic producers and growers. UK organic milk production increased from 17 million litres in 1997/8 to over 300 million litres in 2005/6. In Wales, in 2005, dairy and milk products represented 26% of the total gross product of Welsh... |

| Agriculture at Pwllpeiran has a long history. Pwllpeiran was eventually established as an Experimental Husbandry Farm in 1955. During the following forty years, work at the farm achieved substantial improvements in the quality and quantity of lamb and beef produced, but by the turn of the millennium the emphasis of agricultural policy was turning away from increased livestock production per se and towards the development of environmentally sensitive farming systems. The 1,118 ha Pwllpeiran Research Farm is now managed by ADAS Wales. The land is rented from the National Assembly for Wales and the Forestry Commission. All of the land is under a ‘whole farm’ Environmentally Sensitive Area agreement. The results from the Pwllpeiran unit underline the... |

| There is a widespread assumption that conversion of livestock production systems in the uplands can be achieved with minimal change to existing hill farming practices and yet still deliver environmental and financial benefits. This assumption needs to be examined because conversion of upland farm enterprises poses particular issues for organic farming, Frost (1999). The certifying bodies acknowledge that some of these issues are not adequately covered by the current standards for organic agriculture. The development of a hill farming organic system at Pwllpeiran was established to provide evidence for such an appraisal, Powell (1999). Appraisal of the project indicates that organic beef and sheep production can be a viable option in the uplands. Long... |

| The demand for organically raised tree and hedging plants had been reported from organic farmers in Tir Gofal, as well as within the landscaping industry. Although there are a number of plant raising nurseries producing organically raised plants for vegetable and fruit production, there are no tree nurseries producing to organic standards. Nursery tree growers were concerned that there was currently too little known about the performance of tree seedlings in organic substrates (e.g. in root-trainers), nor about the nutrient supply to seedlings under organic regimes, nor about diseases control (especially fungal diseases such as mildew). Therefore, the development of three hedging species; Hawthorn, Hazel, Blackthorn, were tested for two growing systems in... |

| The technical guide addresses the issues relevant to the organic beef and sheep sector, acknowledging the questions that are frequently directed to the technical ‘Helpline’ of Organic Centre Wales. It draws on the experience of the ADAS Research Farm at Pwllpeiran and is intended as a guide for those with an interest in organic beef and sheep production production. This guide is in three interrelated parts. The first part deals primarily with technical issues of grassland and beef and sheep management, and provides practical information for farmers on key factors influencing the performance of the system. The upland organic unit at ADAS Pwllpeiran in mid-Wales was set up in 1993 to examine the feasibility of organic beef and sheep production in... |

| Organic farming shares many characteristics with other new social movements that emerged in the late twentieth century concerned with environmental conservation and animal rights. In common with these, organic farming has to confront the issues of incorporation and integration that arise when seeking mainstream political support. In the UK, the Organic Conversion Information Scheme (OCIS) and the Organic Farming Scheme are examples of the incorporation and integration of the organic farming movement into government policy. Delivery of the first phase of the Organic Conversion Information Scheme in Wales between 1996 and 2001, involved the setting up and development of a database of all farmers in Wales who requested advice and information under the scheme.... |

| This report was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR).Under EU organic livestock regulations introduced in 2000, new restrictions were placed on the use of bought-in feedstuffs in hill systems. These reduced the non-organic annual percentage previously allowed in LFAs from 20% to 10% of annual dry matter intake. A further stepping down of these allowances may be introduced ahead of a complete ban in 2005. Bought-in feed supplements must therefore, be used strategically and offer “best value for money” in terms of ewe performance and lamb growth. The economic cost of supplementing the diet of twin-rearing ewes post lambing with either an approved non-organic feed block + half ration of commercial... |
