| Research draws on an organic research farm site in central England with a temperate zone climate - fairly common for the northern lowlands of Europe. The soil type is a sandy loam with 591 mm rainfall. Detailed economic and agronomic data have been collected since conversion began in 1995. The economic analysis discusses rotational gross and net margins of more than 30 different rotations with different fertility building and vegetable crops (potatoes, cabbages, onions, carrots, leeks and parsnips). Sensitivity and risk analysis of key variable costs important for successful organic vegetable production are shown. Rotational gross margins varied from –570 €/ha to 6,341 €/ha. Highest output-risk was introduced by yield variations, not price variation.... |

| The use of contentious inputs linked to plant protection, and the use of peat, plastic and fertilisers used in growing have been mapped in selected organically produced crops in 10 countries across Europe. This report refers the output of this mapping. It shows that organic production has not come very far to phase out peat or plastic. The consumption of these materials seems to be quite comparable to non-organic production systems.The main utilisation of peat is for production of young plants (transplants). Most organic growers purchase plants e.g. for citrus, olives and grafted tomatoes and the growing media has usually a high content of peat. Vegetable transplants are also commonly produced by special growers. Peat is also used for casing layers for... |

| Most fresh organic vegetables are produced in intensive rotations, which rely heavily on large inputs of nitrogen to maintain the yield and quality of produce demanded by customers. Field vegetable crops often use nitrogen inefficiently and may leave large residues of nitrogen in the soil after harvest, which can lead to damage to soil, water and air quality. The four-year project EU-ROTATE_N "Development of a model-based decision support system to optimize nitrogen use in horticultural crops rotations across Europe" aims to reduce some of these problems. The project, led by HRI Wellesbourne, started in January 2003 and involves seven research organizations from countries in northern, central and southern Europe. Work includes the evaluation of the effects... |

| This briefing aims to summarise the most relevant recent scientific publications that critically assess the productivity and sustainability of organic farming methods. The rapid increase in the quantity of scientific literature on this topic reflects the growing importance of the sector as well as the need for accurate data and analysis to inform policy makers. There are currently 2.7 million organic-certified farmers (of which 350.000 are in Europe) who have committed to sustainable farming practices. Can organic food and farming be upscaled in order to contribute to sustainable food system and food security? |

| This deliverable presents the results of the survey carried out in the frame of Tasks 3.1. and Task 5.1 in the Horizon 2020 Project Organic PLUS. A common table/questionnaire for both tasks was used in order to map the use of contentious inputs linked to plant protection (mainly Cu, S and mineral oils), and the use of peat, plastic and fertilisers used in growing, in 10 countries participating in Organic-PLUS (Denmark, France, Germany, Greece, Italy, Norway, Poland, Spain, Turkey and UK). The survey was carried out mainly by interviewing one to three experienced advisors per crop, asking them to fill in a table describing a typical organic production of the relevant crop, emphasising the use of various inputs. In some cases the survey was based on already... |

| A recent Horizon 2020-call asked for research to phase out contentious inputs from organic agriculture. During 2018-2021, Organic-PLUS, led by Coventry University, UK will identify and evaluate such inputs, provide technical solutions to phase them out, and assess economic, environmental and social effects of such changes. The project is is funded as a Research and Innovation Action under Horizon 2020-SFS-08-2017. |
