| This dissertation focuses on the research question: what is peculiar to agricultural research when its purpose is to support the conscious development of organic agriculture?What approaches, designs and methods are used for such research? Since the 1990s the Louis Bolk Institute has become one of the important actors in the field of organic research and development. The author analysed the methodological aspects of seven case studies,each following the same format: background of the project, methods used, a reflection on the methods and, to a limited extent, agronomic results. Each of these sheds light on an aspect of the Louis Bolk Institute’s approach to research. Organic farming is experienced as a new paradigm and its research methods need to do... |

| Organic livestock farming has its own concept of health and welfare. The approach to health can be characterised by the key words human, preventive, self-regulating and holistic (Chapter 1). This has consequences for the way we deal with diseases and problems, the nature of the solutions and the use of medication, among other things. In terms of therapeutic and regulatory measures this health concept is based primarily on natural food supplements and homeopathic remedies, which in view of their origin fit in well with the natural character of organic agriculture (Verhoog et al., 2002). Apart from various forms of potentised remedies (classic, clinical, anthroposophic, isopathic; Chapter 2) and all manner of applications within phytotherapy (Bach flower,... |

| The process of spontaneous degradation of milk at 20oC was compared with other analytical quality parameters in milk. Biodynamic milk showed a higher oxidation of the milk fat and a longer renneting time. Conventional milk often tasted better. There is a correlation between several hygienic parameters in milk (germ count, etc) and the quality of degradation. However, the total germ count could not explain all differences and the question was raised if biodynamic milk might have a better resistance to degradation due to a specific bacterial flora or other defence mechanisms in the bio-dynamic milk. |

| In de biologische veehouderij is behoefte aan een minder 'chemische' en meer 'natuurlijke' benadering van ziekten. Wanneer gekozen moet worden voor een complementaire geneeswijze, wordt die keus bemoeilijkt door het grote scala aan geneeswijzen, allemaal met bijpassend gedachtegoed. Eén uitgangspunt voor het kiezen van een geneeswijze kan zijn hoe wilde dieren met ziekte en gezondheid omgaan. Er zijn talloze voorbeelden gedocumenteerd hoe wilde dieren met ziekten omgaan, bijvoorbeeld door het eten van geneeskrachtige planten of andere medicinale grondstoffen. Dit principe wordt zelfmedicatie genoemd, waarvan zowel preventieve als curatieve voorbeelden bekend zijn. Fytotherapie is een geneeswijze die gebaseerd is op geneeskrachtige planten en zou,... |

| At the biodynamic farm Juchowo, 7 pairs of dairy cows from 2 breeds (Holstein (HF) and Brown Swiss (BS)) were milk sampled in summer and in winter. Cows are grazed in summer and fed hay in winter. Differences in the milk fatty acid profile were evaluated for effects of month (fodder), breed and individual cows. The most important way to improve the FA quality is through grazing of fresh grass. Therefor milk from grass based systems should be preferred. Overall breed effects were small, but there are still possibilities present to select individual cows to get an improved FA quality profile in terms of CLA, n-3 FA and delta-9-desaturase activity. |

| Milk as one of the most important nutritional sources has also become one of the major food allergens. What are the reasons for differences of milk from organic and conventional origin? The ongoing research shows a high impact of management practices on milk quality and composition. Which quality characteristic marks consis-tently organic milk quality and how could quality be optimized? The planned transdis-ciplinary and participative project combines analytical and holistic methods to assess organic milk quality and to evaluate the impact on human health. |

| In this paper the differentiation made within the concept of naturalness will be used to explain the different approaches in breeding within the organic movement. The differentiation of the concept will result into a framework, which will be used as a tool to describe and explain the elements of bio-dynamic animal breeding. Bio-dynamics is a practical result out of the anthroposophical worldview. Bio-dynamics developed its own way to judge about relationships in the physical world, used its own language to express the holistic approach in agriculture and focused on additional relationships within the world. |

| The spontaneous degradation of milk at 20oC was investigated within a Goetheanistic approach to determine the milk quality. Two opposite degradation processes were found. One extreme were milk samples that got sour within 1 1/2 day and showed no further changes. The pH was stable at about 4.0. Only a grey mould deck covered the cream at the top. This extreme was called the acid pole. On the other side, milk sam-ples remained fluid over 5-7 days period. Taste became even more intensive after day 2-3 (like roasted nuts). Fungi were flat growing and very colourful in red and yellow. The casein was clotting very slowly at the bottom of the glass and tended to be solu-ble in the end and the fat layer became thinner every day. The pH of this milk never came... |

| This Part describes the agronomic results of the multidisciplinary grassland study. This project concerned the effects of clover varieties and spring applications of animal manure on the yield of grass-white clover mixtures on a moist sandy soil (1993-1996). To be aware of the context of the findings in a multidisciplinary approach, attention was paid to: chemical soil fertility, damage to clover by slugs and soil borne nematodes. To increase the understanding of soil fertility, earthworm dynamics were also measured. At the end of the period the botanical composition of all plots was assessed. Factors measured besides total yield and clover yield were N, P and K yield. It was found that these ‘context ’-measurements were important for the overall... |

| Experiential science is based on the unique knowledge gathered by experienced practitioners. Both the reflective evaluation of case studies and expert judgement processes and the use of pattern recognition are core elements of experiential scien-tific methodology. Development of experiential knowledge and insights are thus pri-marily based on experts’ actions and the reflections on those actions. The methodol-ogy has been created based on intensive cooperation between single farmers or farmer groups and scientists/advisors. Experiential knowledge is not only holistic, but also adequate. As in formal science, experienced practitioners develop valid knowl-edge and in new, unknown situations they have a capability to integrate their diagno-sis (“knowing... |

| Demeter Milch wird aufgrund ihrer Erzeugungsbedingungen gerne mit Gesundheit in Zusammenhang gedacht. Was sagt die Forschung dazu und welche Merkmale werden miteinbezogen? Mit welchen landwirtschaftlichen Maßnahmen ist das in Verbindung zu bringen? Sommermilch ist generell besser als Wintermilch aufgrund der Futterqualität bzw. dem Angebot an "frischem" Futter. Saison und Region beeinflussen die Qualität stark. Gebirgsregionen haben bessere Chancen für eine gute Milchqualität durch den ganztägigen Weidegang der Tiere und die hohe Wachstumsgeschwindigkeit der Vegetation. Das reiche Angebot grüner Pflanzen (Chlorophyll) und Kräuter führt zu hohen Gehalten an Alpha-Linolensäure in der Milch. |

| In het verleden is al aangetoond dat de biologische productiemethode maatschappelijke voordelen heeft op terreinen als milieu, biodiversiteit, bodemkwaliteit, dierenwelzijn en pesticidenresidu. Indirect dragen deze kwaliteiten bij aan de gezondheid van de mens. Nu beginnen ook steeds meer onderzoeksresultaten beschikbaar te komen waaruit blijkt dat de biologische productiemethode ook leidt tot voedsel dat meer gezonde stoffen bevat. Biologische producten blijken gemiddeld gelijk of hoger te scoren op gezonde stoffen o.a. vitamine C gehaltes, mineralen, anti-oxidanten en eiwitkwaliteit dan reguliere producten. En biologische producten blijken gelijk of lager te scoren op ongezonde stoffen zoals nitraat, residuen van bestrijdingsmiddelen en... |
