Organic farming: technology transfer (Environmental impact and soil fertility) (OF0405) Organic Eprints
Shepherd, Mark; Pearce, Bruce; Cormack, Bill; Philipps, Lois; Cuttle, Steve; Bhogal, Anne; Costigan, Peter; Unwin, Roger.
This project covered two separate activities, but both were examples of technology transfer, relating to organic farming: 1. Developing a science-based report, which covered an assessment of the environmental impacts of organic farming. Defra’s Action Plan to Develop Organic Food and Farming included as Annexe 3 an assessment of the environmental impacts of organic farming. This paper was prepared by a Subgroup of the Action Plan for Organic Farming. Its purpose was to summarise the Subgroup’s views of the likely comparative effects of organic and conventional farming on the environment. However, to be robust and defensible, the assessment needs to be supported by scientific data. Although the report was based on such an assessment, the scientific...

Transitions to Agroecological Systems: Farmers’ Viewpoints Organic Eprints
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...

100% Organic Feed for Poultry – Results of Feed Trials in the UK Organic Eprints
Gerrard, Catherine L.; Smith, Jo; Nelder, Rebecca; Clements, Ruth; Pearce, Bruce; Bright, Ashleigh.
Current regulations for organic monogastric production systems permit feed ingredients of non-organic origin, primarily due to concerns about meeting the demand for the essential amino acids methionine and lysine. However, 100 % organic diets will become compulsory in the EU from 1st January 2015, so there is a need to develop feeds which will supply the required level of nutrients and support high animal health and welfare. This paper reports on feeding trials carried out with broilers in the UK to investigate the impact of three 100 % organic diets: a control diet with globally sourced ingredients, a diet based on locally sourced (i.e. within Europe) organic ingredients, and a diet based on locally sourced organic ingredients and algae. The results of...

UK farmers’ transition pathways towards agroecological farm redesign: evaluating explanatory models Organic Eprints
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’...

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 Organic Eprints
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.

Between Sheds Migration: establish whether, and if they do how far birds migrate between field sheds on the Sheepdrove Organic Farm silvo-poultry production system Organic Eprints
Pegg, Vanessa; Pearce, Bruce.
Sheepdrove Organic Farm was concerned about the possibility of birds of different ages mixing within their silvo-poultry system resulting in variation in the bird weights at depletion. A trial was established to investigate whether birds did migrate and if so how many and how far.

Using legume-based mixtures to enhance the nitrogen use efficiency and economic viability of cropping systems. Organic Eprints
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.

Transitions to Agroecological Systems: Farmers’ Experience Organic Eprints
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.

Does the Source of Chicks have an Impact on Performance of Birds within Organic Table Bird Production Systems ? Organic Eprints
Pegg, Vanessa; Pearce, Bruce.
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...

Public goods and farming Organic Eprints
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.

OCIS Public Goods Tool Development Organic Eprints
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...

The Establishment of a Preliminary Weight Profile for the 257 Table Birds within the Sheepdrove Organic Farm Organic Silvo-Poultry System. Organic Eprints
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.

The Role of Agroecology in Sustainable Intensification Organic Eprints
Lampkin, Nicolas; Pearce, Bruce; Leake, Alastair; Creissen, Henry; Gerrard, Catherine L; Gerling, Robbie; Lloyd, Sofie; Padel, Susanne; Smith, Jo; Smith, Laurence; Vieweger, Anja; Wolfe, Martin.
‘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. This includes addressing issues of...

Organic Cereal Varieties: The Results of four years of Trials Organic Eprints
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...

100% Organic Feed for Pigs – Results of Feed Trials in the UK Organic Eprints
Smith, Jo; Gerrard, Catherine L.; Nelder, Rebecca; Clements, Ruth; Pearce, Bruce; Zaralis, Konstantinos.
Current regulations for organic pig and poultry production systems permit feed ingredients of non-organic origin, primarily due to concerns that a 100 % organic diet would be unable to meet the demand for the essential amino acids lysine and methionine. 100 % organic diets for monogastrics will become compulsory in the EU from 1st January 2015, and so there is an urgent need to develop economically profitable feeding strategies based on organic feed across Europe. Feeding trials carried out with Gloucester old spot pigs in the UK found that there was no significant difference in the weight gains across the diets until the last week of the trial when there a significant difference in weight increase for the male pigs on the bean diet. This suggests that a...
