Provedor de dados: 21
Autores: Padel, Susanne; Niggli, Urs; Pearce, Bruce; Schlüter, Marco; Schmid, Otto; Cuoco, Eduardo; Willer, Helga; Huber, Machteld; Halberg, Niels; Micheloni, Cristina.
The Implementation Action Plan completes TP Organics’ trilogy of key documents of the Research Vision to 2025 (Niggli et al 2008) and the Strategic Research Agenda (Schmid et al 2009). The Implementation Action Plan addresses important areas for a successful implementation of the Strategic Research Agenda. It explores the strength of Europe’s organic sector on the world stage with about one quarter of the world’s organic agricultural land in 2008 and accounting for more than half of the global organic market. The aims and objectives of organic farming reflect a broad range of societal demands on the multiple roles of agriculture and food production of not only producing commodities but also ecosystem services. These are important for Europe’s economic...

Public goods and farming
Provedor de dados: 21
Autores: Gerrard, Catherine L; Smith, Laurence; Pearce, Bruce; Padel, Susanne; Hitchings, Roger; Measures, Mark.
There has recently been an increase in interest in the “public goods” that could be provided by a farm alongside its primary function of agricultural production.  This paper reviews recent reports on the topic of public goods and, in particular, the public goods provided by agriculture and then goes on to discuss the development of a tool which can be used to assess the provision of public goods on a farm  across a range of areas: soil management, biodiversity, landscape and heritage, water management, manure management and nutrients, energy and carbon, food  security, agricultural systems diversity, social capital, farm business resilience, and  animal health and welfare.

Wheat trials - How reliably do wheat varieties perform under different organic farming conditions?
Provedor de dados: 21
Autores: Döring, Thomas F.; Haigh, Zoe; Pearce, Helen; Pearce, Bruce; Jones, Hannah; Clarke, Sarah; Wolfe, Martin.
A major obstacle in the development of organic farming in the UK is the central problem of winter wheat production. At present, there is a substantial gap between the supply of home-grown organic milling wheat and demand, partially due to shortfalls in both wheat yield and quality. Progress is being made in organic wheat breeding programmes across Europe, although the varieties arising from these are not widely available in the UK. A crucial and unanswered question is how reliably varieties will perform under the diverse conditions that prevail on organic farms. Wheat trial results reported here indicate that the main effects of variety, location, year, or farming practice may often be more important than the complex interactions among these factors....

The Establishment of a Preliminary Weight Profile for the 257 Table Birds within the Sheepdrove Organic Farm Organic Silvo-Poultry System.
Provedor de dados: 21
Autores: Pegg, Venessa; Dyke, Kirstie; Philipps, Lois; Phillips, Scott; Pearce, Bruce.
A preliminary weight profile was produce for the organic silvo-poultry system on Sheepdrove organic farm. Seven batches (each of 20 hens and 20 cocks) were weighed over a two month period (January/February 2003). No current organic silvo-poultry weight profile was available but the weights achieved were found to exceed those of the nearest suggested profile (ISA 657) but were beneath the weights required for Sheepdroves markets. There was great and inconsistent variation between the batches and between sheds. This suggested that environment and management of particular houses could be having a large impact on final chicken weights.

A review of knowledge of the potential impacts of GMOs on organic agriculture
Provedor de dados: 21
Autores: Dale, Phillip; Clarke, Belinda; Fontes, Eliana; Martin, Wolfe; Pearce, Bruce; Welsh, James.
The organic movement believes that organic agriculture, by its nature, cannot involve the use of genetically modified organisms (GMOs).  This has been incorporated into EU regulations which state that there is no place in organic agriculture for GMOs.  The aim in this review is to consider the ways in which the use of GMOs in agriculture in the UK and internationally might impact on organic farming.  It does not address the controversy about the rights or wrongs of GMO’s per se.  The subjects covered are based on a set of questions raised at the beginning of the study.  The review is based primarily on evidence from peer-reviewed literature.    The report is based on a number of themes, as follows:  • Fate of DNA in soil  • Fate of DNA in livestock feed...

Transitions to Agroecological Systems: Farmers’ Viewpoints
Provedor de dados: 21
Autores: Padel, Susanne; Rubenstein, Oliver; Woolford, Amelia; Egan, Jim; Pearce, Bruce.
We report a social science study of farmers’ experience of transition towards agroecological approaches in the UK with the aims to   (i) identify motivations, challenges and opportunities encountered, together with the perceived benefits and disadvantages associated with the transition and   (ii) gain an understanding of individuals’ trajectories in context, including social, economic, biophysical, cultural and psychological dimensions.   Fourteen farmers in England, Scotland and Wales that had undergone an agroecological transition were interviewed in early 2017 using a semi-structured interview case study approach. Answers were analysed, considering mainly two theoretical models of farmers’ decision-making.  Key triggers were farmers newly taking over a...

Using legume-based mixtures to enhance the nitrogen use efficiency and economic viability of cropping systems.
Provedor de dados: 21
Autores: Baddeley, J. A.; Döring, Thomas F.; Hatch, David; Marshall, Athole; Pearce, Bruce; Roderick, S; Stobart, Ron; Storkey, Jonathan; Watson, C.A.; Wolfe, Martin.
There is a pressing need to develop arable cropping systems that are both more efficient in their use of nitrogen (N) and more resilient to an increasingly variable and unpredictable climate. One potential solution is to use species-rich mixtures of grasses and legumes in the fertilitybuilding phase of a ley/arable crop rotation. These mixtures may reduce N losses and increase productivity of the following crop. They may also have other important benefits such as increased in-field biodiversity. In this project, legume and grass species with a range of tolerances to different environmental conditions, and with differing growth characteristics, are being grown individually and as a mixture across the UK, and their performance assessed.

Autores: Padel, Susanne; Rubenstein, Oliver; Woolford, Amelia; Egan, Jim; Leake, Alastair; Levidov, Les; Pearce, Bruce; Lampkin, Nicolas.
The term agroecology is used mainly to describe an approach “emphasising ecological principles and practices in the design and management of agroecosystems, one that  integrates the long-term protection of natural resources as an element of food, fuel and fibre production” (Lampkin et al., 2015, P9). Agroecological approaches in farming can make a major contribution to the sustainable intensification of agriculture in the UK but there is no specific policy framework for ‘agroecology’ in the UK.   Building on a previous builds on the LUPG report by Lampkin et al. (2015) on the contribution of agroecology to sustainable intensification the report present a short background section, the approach, results and conclusion.

Further Development of Methodologies for Sustainability Assessment and Monitoring in Organic/Ecological Agriculture
Provedor de dados: 21
Autores: Padel, Susanne; Gerrard, Catherine L; Smith, Laurence; Schader, Christian; Baumgart, Lukas; Stolze, Matthias; Pearce, Bruce.
In recent years there has been a great deal of interest in assessing the sustainability of agriculture in terms of its social, environmental and economic impact and a number of indicators and tools are used. Measurements take place at the farm or product level and indicators can be outcome related e.g. number of butterfly species present, or management related e.g. percentage of fields with margins growing wildflowers to attract butterflies.     Given its underlying ethos, the organic/ecological agriculture sector should aim to be at the forefront of sustainability. The development of assessment approaches and recent discussions within the movement have identified continuous improvement towards best practice in sustainability to be one of the important...

Organic Cereal Varieties: The Results of four years of Trials
Provedor de dados: 21
Autores: Pearce, Bruce.
Modern breeding has focussed on producing plants that perform well in a monoculture; they are designed to interfere minimally with their neighbours under high fertility conditions, where all ameliorable factors are controlled. The aim of this design is to provide a crop community that makes best use of light supply to the best advantage of grain production. Wheat is the most developed example of this approach - with a high proportion of seminal roots, erect leaves, large ears and a relatively dwarf structure - but all other cereal breeding follows it.  This 'pedigree line for monoculture' approach is highly successful but it has delivered crop communities that do best where light is the only, or the main, limiting factor for productivity. Therefore the...

As costs for mineral fertilizers rise, legume-based leys are recognised as a potential alternative nitrogen source for crops. Here we demonstrate that including species-rich legume-based leys in the rotation helps to maximize synergies between agricultural productivity and other ecosystem services. By using functionally diverse plant species mixtures these services can be optimised and fine-tuned to regional and farm-specific needs. Field experiments run over three years at multiple locations showed that the stability of ley performance was greater in multi-species mixtures than in legume monocultures. In addition, mixing different legume species in the ley helps to suppress both early and late weeds. Further, combining complementary phenologies of...

Autores: Pearce, Bruce.
It was thought that weather, and in particular air temperature, could be a major factor in SOF poultry failing to reach its target market weight of 1.83kg kill out weight.  This study used data form the SOF processing plant for the average bird weight for the twice weekly processing of the birds and hourly air temperature from an automated weather station sited on SOF which was averaged over the seven weeks prior to processing (the time the birds spend in the field sheds.  The data between 20th January and 3rd September 2003 showed that there was no relationship between air temperature and final bird weight.

To establish whether there are differences in performance between 757 (Lloyd Maunders) birds and the Maurice Millard 257 those currently used within the Sheepdrove system
Provedor de dados: 21
Autores: Pegg, Vanessa; Aspray, Claire; Pearce, Bruce.
Sheepdrove Organic Farm wanted to know whether the performance of the Lloyd Maunders (757) birds would differ from that of their current breed the Maurice Millard (257) and whether chicks sourced from an organic parent flock would perform differently to those from a conventional parent flock.  An experiment was undertaken using two different sources of day old chicks, 1000 day old Maurice Millard (257) and 1000 day old Lloyd Maunders (757). These chicks were then put through the Sheepdrove (SOF) organic production system and 30 random birds were weighed every week until depletion, at 11 weeks.

Autores: Pearce, Bruce; Lampkin, Nicolas; Leake, Alastair; Padel, Susanne.
This paper explores how agroecological approaches can contribute to sustainable intensification. There is an ongoing debate on how we can produce the required levels of food the world needs on existing farmland, while minimising environmental impacts. The ‘sustainable intensification’ concept has been proposed to reconcile these two objectives.  In parallel, there is a growing interest in how agroecological approaches can contribute to the world’s food security. We reviewed the evidence for a large range of agroecological practices and made a close comparison between conventional agricultural systems and integrated agriculture, organic farming and agroforestry, comparing on a range of factors.  Overall, the study found that agroecological approaches can...

At present, around 95% of organic production is based on crop varieties that were bred for the conventional high-input sector, lacking important traits required under organic and low-input production conditions. Populations with a high level of genetic diversity are promising for OA (organic agriculture) conditions due to their adaptation, resilience and performance stability in different environments. Organic farming will benefit from cultivars (populations, varieties) that can cope with multiple stresses such as weeds, diseases, pests, climate change and low nitrogen input from manure. In the COBRA project (Coordinating Organic Plant Breeding Activities for diversity), plant genetic diversity and its potential have been investigated from both an...

Assessing the public goods provided by organic agriculture: lessons learned from practice
Provedor de dados: 21
Autores: Smith, Laurence; Padel, Susanne; Pearce, Bruce; Lampkin, Nic; Gerrard, Catherine L; Woodward, Lawrence; Fowler, Sue; Measures, Mark.
The role of farms as providers of public goods has long been recognised, and measuring performance in this area is of increasing interest to policy makers, in light of the approaching Common Agricultural Policy reform. The Organic Research Centre has been working on this topic in recent years, through the development of sustainability assessment tools. The latest outcome from this process is a ‘Public Goods’ assessment tool, developed through a Natural England funded project which aimed to evaluate the benefits accruing from organic management and entering into an Organic Entry Level Stewardship (OELS) agreement. This paper describes the development of the Public Goods (PG) tool, and what has been learned in the process.

Plant breeding is crucial in creating organic crop production systems that can better cope with interacting stresses such as pests and diseases (especially seed-borne diseases), weeds and the increasingly erratic and unpredictable variation in climate and weather. In this context, COBRA aimed to support and develop organic plant breeding and seed production with a focus on increasing the use and potential of plant material with high genetic diversity in cereals (wheat and barley) and grain legumes (pea and faba bean), through coordinating, linking and expanding existing breeding and research. Although systems based on high, within-crop diversity have shown promising results in organic systems and are now subject to intensive research, their benefits cannot...

Developing modern multifunctional agroforestry systems for sustainable intensification
Provedor de dados: 21
Autores: Smith, Jo; Pearce, Bruce; Döring, Thomas F.; Wolfe, M S.
Agroforestry is a land-use system that integrates trees and shrubs with crops and/or livestock production. It has been identified by the International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD, 2008) as a ‘win-win’ approach that balances the production of commodities (food, feed, fuel, fibre, etc.) with non-commodity outputs such as environmental protection and cultural and landscape amenities. This paper will review the potential of agroforestry as part of a multifunctional working landscape in temperate regions, and will consider management and policy implications of widespread adoption of this form of land-use.

The Effect of Removing Synthetic Amino Acids from the Poultry Ration on the Final Live and Dressed Weight of Birds from the Sheepdrove Organic Farm Organic Silvo-Poultry System
Provedor de dados: 21
Autores: Pegg, Vanessa; Pearce, Bruce.
Organic standards and aspirations are moving towards the removal of synthetic amino acids from organic poultry rations. Sheepdrove Organic Farm has already removed synthetic amino acids from the rations fed to its chickens.  Data was collected on live and dressed weight of processed birds, before, during and after the removal of synthetic amino acids from the ration.  There does appear to be a detrimental effect on the final weight (both live and dressed) of birds raised without synthetic amino acids although this loss of weight has been overcome with the increase in production time from 10 to 11 weeks.

‘Sustainable intensification’ is now often used to describe the future direction for agriculture and food production as a way to address the challenges of increasing global population, food security, climate change and resource conservation. While sustainable intensification is interpreted by some to relate to increasing production, with more efficient but potentially increased use of inputs and technology, there is also a need to consider environmental protection, including the conservation and renewal of natural capital and the output of ecosystem services. There is a growing consensus that sustainable intensification should not only avoid further environmental damage, but actively encourage environmental benefits.

A comparison of soil and water properties in organic and conventional farming systems in England
Provedor de dados: 21
Autores: Hathaway-Jenkins, L. J.; Sakrabani, R; Pearce, Bruce; Whitmore, A. P; Godwin, R. J.
Organic farming and improvements to agricultural sustainability are often seen as synonymous. However, an extensive European review demonstrated that in practice this is not always true. This study aims to compare the status of soil and water properties between separate fields managed in either an organic or a conventional manner. Soil samples were collected from 16 pairs of farms, throughout England, with both arable and grass fields within each pair on similar soil type. Chemical (nutrients, pesticides, herbicides) and physical (aggregate stability, field capacity, shear strength, soil organic matter, infiltration rates) soil properties were measured in four main soil texture classes in organic and conventional fields.

OCIS Public Goods Tool Development
Provedor de dados: 21
Autores: Gerrard, Catherine L; Smith, Laurence; Padel, Susanne; Pearce, Bruce; Hitchings, Roger; Measures, Mark; Cooper, Nick.
There has recently been an increase in interest amongst policy-makers in the question of whether farming provides a “public good” beyond the simple production of food, which justifies support from, for instance, EU agricultural policy. Benefits such as an improved environment or better water quality can be perceived to be public goods. It is the provision of these sorts of benefits which may be used in the future to justify continued support of the agricultural sector through subsidies.    Given the current level of interest in this topic Natural England, with the approval of Defra, through OCIS (Organic Conversion Information Service), wished to create a tool which could be used by an advisor or an informed land owner to assess the public good provided by...

Sheepdrove Organic Farm wanted to know whether the source of day old chicks and brooding and production period would have an impact on their enterprise. Sheepdrove Organic Farm wanted to know whether the source of day old chicks and brooding and production period would have an impact on their enterprise.  An experiment was undertaken using two different sources of day old chicks and on two sites. 1000 day old chicks from Maurice Millard were exchanged with 1000 organic chicks from Devon Foods. These chicks were then put through the Sheepdrove (SOF) and Devon Foods Bradbury Barton (BB) organic production systems and weighed every week until depletion.  The two systems were not identical and there were slight variations between the SOF and BB systems. BB had...

UK farmers’ transition pathways towards agroecological farm redesign: evaluating explanatory models
Provedor de dados: 21
Autores: Padel, Susanne; Levidov, Les; Pearce, Bruce.
Although the organic conversion process has been much studied, farm-level transitions to agroecosystems are less well understood. What transition pathways do they take? How can (or does) farmers’ learning help to make such changes? What support measures can (or do) facilitate such learning? To answer such questions, a UK study identified farmers undergoing an agroecological transition and compared their practices with two prevalent models. As regards the Efficiency – Substitution – Redesign (ESR) model, our case-study farms had all three changes, but they were rarely sequential; agroecosystem redesign did not follow from Efficiency or Substitution measures, which readily provide endpoints rather than transitional stages. As regards the ‘trigger events’...

As environmental and agronomic conditions are heterogeneous between and within locations, diversity within varieties or crop populations should increase adaptability to the changing and variable range of growing environments. The additional pressure of plant genetic diversity loss, has driven novel breeding approaches such as Composite Cross Populations (CCPs) and other genotype mixtures, thereby increasing both intra- and inter-varietal diversity and ensuring a “wider adaptation” capacity for crop varieties (Döring et al., 2011). A winter wheat (Triticum aestivum L.) CCP was created by intercrossing 20 varieties in 2001, through collaboration with the Elm Farm Research Centre and the John Innes Institute. In 2005, a seed batch of the F4 was equally...
