| The objective of this paper was to investigate the effect of limited grazing time on urination and defecation frequency, spatial distribution of excrement in the paddock, and the resulting nitrogen balance at animal and field level. During a 6-week period in early summer, 60 Holstein Frisian dairy cows (31.0±5.4 kg ECM) were randomly allocated to three different treatments, with grazing at clover-grass pasture during daytime for 4, 6.5 or 9 h daily. Indoor feeding, with a mixture of roughage and concentrates (13% crude protein), was restricted for treatment 4 and 6.5 h to the amount the 9-h treatment could eat. Cows allowed grazing at pasture for 4 h moved more rapidly during pasture, moved longer distance per active hour and used a higher proportion of... |

| 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... |

| 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... |

| The objective of this survey was to assess economic, ecological and societal sustainability aspects when introducing automatic milking systems on organic dairy cattle farms. The assessment is made in close relation to the stakeholders that have been determined. This assessment is based on current available knowledge which does not differentiate between organic and conventional management.Net farm income on conventional dairy farms introducing AMS does not increase significantly,neither is this expected for organic AMS farms. The time saving effect results in social but not economic advantages. Introduction of AMS on conventional farms in combination with grazing,results in a small increase in fossil energy use per kg milk, and an increase in eutrophication... |

| EGTOP (= the Expert Group for Technical advice on Organic Production) aims to provide advice to the European Commission concerning the authorisation of the use of products, substances and techniques in organic farming and processing, to develop or improve organic production rules and, more in general, on any other matter relating to the area of organic production. Frank Oudshoorn from SEGES, Denmark participates in EGTOP since 2018, and he is also active in several work packages in the Organic-PLUS Project. In this presentation, he described the work in EGTOP, where topics selected to be treated by this Group are described and analysed in a dossier, often written by appointed sub-Groups. EGTOP assesses the dossier and makes a decision (advice). Digestate,... |

| The aim of this study was to explore stakeholder perceptions of the contribution of an Automatic Milking System (AMS) to sustainable development of organic dairy production in Denmark and the Netherlands. In addition, reasons for the current difference in AMS use on organic dairy farms between both countries were explored. To answer above mentioned aims, farmers and advisors in both countries were interviewed using a focus group approach. Questions of the interviews were based on a literature review on sustainability issues affected by introduction of AMS. Participants expressed no moral problems regarding AMS use. They, however, pointed out uncertainty about the economic gain, difficulties with grazing, adaptation problems to technology, and... |
