| 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... |

| 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. |

| Soil chemical properties were correlated with microbial biomass and its activity. Different correlations were found at the beginning of the first and second cycles, respectively. Soil samples were grouped with respect to the different climate zones. The main variables that separated the countries were organic Carbon, total Nitrogen, pH and clay content. |

| 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.... |

| 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 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... |

| 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... |

| 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. |

| 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. |

| 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... |

| 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... |

| 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. |

| The paper illustrates the role and activities of Technology Platform Organics (TP Organics) in addressing the requirement that research in organic food and farming systems generates output of relevance to wider end-users. It describes approaches to research and knowledge exchange and suggests that a more participatory approach can improve organic research outcomes. It describes different models of research and knowledge exchange and their pros and cons. The criteria for success of a participatory approach to research also need to be different. These are discussed. |

| 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. |

| 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... |
