A farmer’s guide to organic fruit and vegetable production Organic Eprints
Little, Tony; Frost, David.
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...

A New Incarnation- The Role of the Organic Growers Association in Changing the Production and Marketing of Organic Produce Organic Eprints
Frost, David; Wacher, Carolyn.
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...

Controlling Ectoparasites on Welsh Organic Sheep Farms Organic Eprints
McLean, Dr Barbara; Frost, David.
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...

Deconstructing the organic movement Organic Eprints
Frost, David.
This report was presented at the UK Organic Research 2002 Conference. Organic agriculture has sought to establish its scientific validity and its origins. Conford (2001) claims that these can be traced to the 1920s, and that Anglican Christianity is pivotal to its history. However, organic agriculture takes many forms and the role of religion in society has changed. In the UK, a new incarnation of organic farming occurred in the late twentieth century as part of a wider response to environmental issues.

Eight years of organic farming at Pwllpeiran – livestock production and the financial performance of organic upland Organic Eprints
Frost, David; McLean, Barbara M L; Evans, D Eifion.
This report was presented at the UK Organic Research 2002 Conference. Established for 8 years, this project evaluates the practicalities of organic beef and sheep production on an upland farm in an ESA. Grassland productivity, stocking rates and animal performance are closely related to seasonal variations in the clover content of the small area of improved land. Improving sales have been offset by increasing input costs. Subsidy payments assist financial performance, but ESA prescriptions effectively prevent increased production.

Environmental and biodiversity impacts of organic farming in the hills and uplands of Wales Organic Eprints
Fowler, Susan; Frost, David; de Carle, Caroline.
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....

Livestock breeds and Organic farming systems Organic Eprints
Van Diepen, Pauline; McLean, Dr Barbara; Frost, David.
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...

Market Review of the Organic Dairy Sector in Wales, 2007 Organic Eprints
Smith, Carolyn; Frost, David; van Diepen, Pauline; Chrisholm, Claire.
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...

Organic Farming at ADAS PwllPeiran 1993 - 2001 Organic Eprints
Frost, David.
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...

Organic farming in the uplands – appraisal of a development programme Organic Eprints
Frost, David.
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...

Organic tree propagation under Welsh nursery conditions Organic Eprints
Frost, David; Clarke, Aldwyn.
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...

Organic Upland Beef and Sheep Production Organic Eprints
Frost, David; Jones, Mark; van Diepen, Pauline; Jackson, Andrew.
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...

Preaching Conversion: The Organic Conversion Information Scheme in Wales, 1996-2001 Organic Eprints
Frost, David.
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....

The environmental and socio-economic impacts of organic farming in Wales Organic Eprints
Frost, David; Ardeshir, Danny; Davies, Owen.
The scientific basis of organic agriculture’s role in benefiting health, the environment and agricultural communities has been the subject of considerable debate. In Wales, a three-year monitoring study found evidence of the compatibility of organic farming with environmental conservation. The study also found a positive attitude towards production issues among organic farmers, but increasing concerns about marketing and profitability.

The inclusion of diatomaceous earth in the diet of grazing ruminants and its effect on gastrointestinal parasite burdens Organic Eprints
McLean, Barbara; Frost, David; Evans, Eifion; Clarke, Aldwyn; Griffiths, Bernard.
Two studies were carried out to assess the efficacy of diatomaceous earth as an alternative to anthelmintics in grazing ruminants. Animals treated with anthelmintics and groups of untreated animals were included for comparison. Cattle and sheep which received the diatomaceous earth supplement had low Faecal Egg Counts (FEC) for the duration of the experimental period, similar to animals in the anthelmintic groups. Inclusion of diatomaceous earth in the diet of grazing ruminants may offer some benefits in controlling internal parasites.

The use of feed blocks as supplementation for the upland hill flock: (2) Cost effective lamb production Organic Eprints
McLean, Barbara M L; Frost, David; Evans, D Eifion.
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...

The use of feed blocks as supplementation for theupland hill flock: (1) Improving organic ewe productivity and performance Organic Eprints
McLean, Barbara M L; Frost, David; Evans, D Eifion.
This report was presented at the UK Organic Research 2002 Conference of the Colloquium of Organic Researchers (COR). Maintaining ewe performance in winter poses particular problems for organic farming in the uplands where the availability of both grazing and home produced forage may be restricted. This trial evaluated approved non-organic feed blocks as dietary supplement for ewes grazing pastures between 300 and 550 m.
