This paper explores how knowledge is exchanged between agricultural advisors and farmers in the context of sustainable farming practices in England. Specifically the paper examines the nature of the knowledge exchange at the encounters between one group of advisors, agronomists, and farmers. The promotion of best management practices, which are central to the implementation of sustainable agricultural policies in England, provide the empirical context for this study. The paper uses the notion of expert and facilitative approaches as a conceptual framework (...) for analyzing knowledge exchange encounters between agronomists and farmers. Data were derived from semi-structured interviews with 31 agronomists and 17 farmers, in the context of three initiatives promoting a range of best management practices including (a) targeted use of nitrogen (N), (b) use of nutrients within manure, and (c) management practices to improve soil structure. The interviews revealed that, although many agronomist–farmer knowledge exchange encounters are characterized by an imbalance of power, distrust, and the divergence of knowledge, other encounters provide a platform for the facilitation of farmer learning in their transition to more sustainable practices.

This article examines differences in the research approaches of farmers and scientists and analyzes how these differences are related to the conditions under which both groups engage in experimental work. Theoretical considerations as well as practical experiences are presented to emphasize the great potential of farmer–researcher collaboration for rural innovation. In the first part of the article, the innovative power of farmer research and experimentation is acknowledged by presenting examples such as crop and animal breeding, development of new production systems, (...) farm equipment, and social innovations. Considering the respective comparative advantages of farmers and scientists, and inspired by theoretical concepts in the fields of knowledge management and innovation processes, we discuss five topics for optimizing the collaboration between farmers and scientists in the field of technological innovation: user orientation, decentralization, informal modes of experimentation, externalization of tacit knowledge, and economic considerations. A better understanding of such issues could help researchers to define their own role in the research process, acknowledge the strengths and weaknesses of their own and farmers’ research approaches, overcome communication gaps, and find creative solutions for problems that typically occur in the process of participatory technology development.

Farmers all over the world perform experiments, and have done so since long before modern experimental science and its recognized forerunners. There is a rich anthropological literature on these experiments, but the philosophical issues that they give rise to have not received much attention. Based on the anthropological literature, this study investigates methodological and philosophical issues pertaining to farmers’ experiments, including the choice of interventions to be tested, the planning of experiments, and the use of control fields and other means (...) to deal with confounding factors. Farmers’ experiments have some advantages over the field trials of agricultural scientists, but also some comparative disadvantages. The two experimental traditions are complementary, and neither of them can replace the other. Several aspects of farmers’ experiments are shown to have a direct bearing on central topics in the philosophy of science. (shrink)

Easy-care or natural lambing pertainsto those sheep able to successfully lamb andrear at least one lamb without human assistancein a difficult environment. Such sheep may havea higher survival rate, lower lamb mortality,and require less shepherding at lambing thanother sheep breeds or strains. The farmer orshepherd account of easy-care lambing revealsseveral themes. Firstly, stock were bred tosurvive or suit local environments orconditions, particularly steep hill country inNew Zealand. This involved extensive culling ofundesirable dams, regardless of how well theymight perform in traits (...) other than the abilityto survive and to produce live lambs atweaning. Sheep that did have problems wereoften assisted, recorded or marked and thenculled at an appropriate time; thus bothartificial (culling) and natural selection wereused. Secondly, natural selection enabled theimportant traits to be identified and they weresubsequently incorporated into artificialselection programs. Thirdly, the practice wasnecessitated by the impracticality ofsupervising lambing in difficult terrain andthe cost of skilled farm labor. Finally, it wasacknowledged that disturbance at lambingcreated problems and most importantly, theeasy-care approach reduced some of the problemstraditionally associated with lambing.Easy-care lambing systems thus aim to minimizesome of the detrimental effects associated withcarefully supervised lambing in someenvironments, by selecting sheep to suit boththat environment and modern farm management.They overcame pervasive influences our culturallegacy was exerting on the way we interact withanimals, and may have produced a system more inkeeping with the biology of the animal in anextensive environment.

Folk experiments in agriculture are often inspired by new ideas blended with old ones, motivated by economic and environmental change. They tend to save labor or capital. These notions are illustrated with nine short case studies from Nicaragua and El Salvador. The new ideas that catalyze folk experiments may be provided by development agencies, but paradoxically, the folk experiments are so common that the agencies that inspire them usually pay little attention to them. Some folk experiments are original, but others (...) simply copy innovations that farmers have seen somewhere else. Unlike formal scientific research, in which results are consistently written, folk experiments are rarely “inscribed,” because the results are for use by individual farmers and need not be shared with an audience.

For further development of organic agriculture, it will become increasingly essential to integrate experienced innovative practitioners in research projects. The characteristics of this process of co-learning have been transformed into a research approach, theoretically conceptualized as “experiential science” (Baars 2007 , Baars and Baars 2007 ). The approach integrates social sciences, natural sciences, and human sciences. It is derived from action research and belongs to the wider field of transdiscliplinary research. In a dialogue-based culture of equality and mutual exchange the (...) principal of a “bottom-up” experiential learning process can be stimulated and fully reflective. It provides an opportunity to develop organic agriculture as multiple best-practices based on transdisciplinary projects, cases studies, and case series. The aim of the article is to describe the methodological characteristics and the theoretical and practical potential of experiential science for research in and development of organic farming. Three characteristic projects are outlined to illustrate the main elements of the methodology: the retrospective reflection on intuitive and experiential knowledge held by farmers; the knowledge derived from on-farm experimentation; the exchange of knowledge and experiences between farming pioneers within a “masterclass” setting. The study concludes that experiential science offers an important philosophical reconciliation process whereby a synthesis of different approaches to research becomes possible in solving real-life problems: quantitative and qualitative, subjective and objective, reductionistic and holistic, practice and science. Recognizing that there are multiple elements contributing to the process of acquiring knowledge, experiential science draws on a broad field of scientific methods thereby integrating the hermeneutic approach of social sciences and the Humanities with the established methods of contemporary natural science.

Part I : Reflection on research methods in organic grassland and animal production at the Louis Bolk Institute, The NetherlandsKey words: organic agriculture, anthroposophy, methodology, research strategy, experiential science, multidisciplinary science, Goethean scienceThis 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 justice to it. Three criteria were formulated for this purpose: the self regulation of farming systems, the involvement of farmers and the respect for the integrity of life. Two conceptual frameworks are used to analyse the research methods: (1) a four-quadrant matrix. Epistemological, ontological and methodological changes in the way of thinking are relevant in discussions about holism versus reductionism and positivism versus constructivism. The second framework is (2) a triangle which can show the relationship between the underlying values, the involvement of the actors and the nature of the scientific process.The scientific position which is defended in this dissertation can ultimately best be described as a 'radical holistic research strategy'.Research approaches applied in the case studies are: interdisciplinary research, experiential science and mutual learning, farmer-to-farmer learning, exploring tacit knowledge, bio-ethical evaluation, Goethean science and systemic development. In the four quadrant matrix two new additional research methods are positioned: (1) Goethean science is included as a holistic counterpart to multidisciplinary system ecology; (2) experiential science is included for comparison with mono-disciplinary experimental research. The constructivist character of both Goethean science and experiential science particularly distinguishes these methods from mainstream science.The meta-reflection on the research showed some important new elements of research. There was a systemic orientation in terms of a cohesive set of management measures and actions. This systemic orientation also encompasses holism in terms of Goethean science. In addition there is the experiential science based on intuitive action and pattern recognition. The reflection on the methods made it clear that their acceptance was influenced by the underlying scientific philosophy.The entire research strategy is thus based on two different interpretations of knowledge. Experiential science focuses on the actions of the farmer and is based on the epistemology of action. In addition there is an epistemology of knowledge, where it relates to interdisciplinary research and Goethean science. There are barriers to the acceptance of these scientific methods in the current lack of suitable statistical evaluation methods, and also in the absence of accepted methods for explicitly exploring reality as constructed by people.Part II : Effects of manure types and white clover (Trifolium repens) cultivars on the productivity of grass-clover mixtures grown on a humid sandy soilKey words: organic agriculture, grass-clover, white clover cultivars, animal manure, potassium, nematodes, earthwormsThis 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 explanation of the scientific results. Data were used for modelling several relationships between yield parameters. The overall findings of this project led to an understanding and description of the main aspects of manure with regard to grass-white clover growth on a moist sandy soil.It was concluded that on a moist sandy soil the amount of inorganic and organic N, the N release and the K input were the main manure factors relating to fluctuations in total yields on white clover development and on N yields in the first six years after sward establishment. The inorganic N component in manure can be used strategically to improve the growth of the herbage in spring. Maintenance of soil fertility in terms of P, K and Ca levels is an important key factor for a successful organic grass-clover sward.Carbon rich FYM derived from a deep litter stable and composted before application increased the earthworm population, reduced the number of nematodes and maintained the highest level of soil pH, all factors which might positively affect white clover growth in the long term. FYM applied in spring resulted in the typical extended growth season in the second part of the growing season. On a sandy soil the high concentration of K in the FYM positively affects the potential white clover growth.The choice of a persistent white clover cultivar is another important factor affecting herbage and N yields of an organic grass-clover sward. However, winter losses were not found to be the main cause of white clover reductions over the years. Losses in the growing season were related to slugs which reduced white clover leaf area. The literature shows that the cyanide concentration in DM herbage affects the susceptibility of white clover to pests. (shrink)
