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.

The agronomist who wants to study the nutrient and water uptake of roots needs a quantitative three-dimensional dynamic model of the structure of root systems.The model presented takes into account current knowledge about the morphogenesis of root systems. It describes the root system as a set of root axes, characterised by their orders. The morphogenetic properties of root axes differ according to their order. The axes of order 1 are directly inserted on the stem, the axes of order 2 (...) are inserted on axes of order 1, and so on. They tend to be more plagiotropec and to have less vascular bundles as the order increases. (shrink)

The study of recent ‘traditional’ Mediterranean rural economy has long been a predilection of ancient historians and archaeologists working in that area. Traditional practices and production norms have been used by ancient historians in the interpretation of the often enigmatic testimony of the ancient agronomic writers, while archaeologists have used the same information to fill in the many gaps in the material record supplied by the spade. Much of the relevant data on traditional rural economy are gleaned from the accounts (...) of early travellers or of modern geographers, ethnographers and agronomists. Butcomparandaacquired at first-hand enhance the credibility of archaeologists and ancient historians as fieldworkers, and chance summer encounters with Cretan shepherds or Cycladic fishermen are valuable currency in competitive displays at academic conferences.

Despite increasing attention to the sensors, drones, robots, and apps permeating agri-food systems, little attention has been paid to social media, perhaps the most ubiquitous digital technology in rural areas globally. This article draws on analysis of farming groups on Myanmar Facebook to posit social media as appropriated agritech: a generic technology incorporated into existing circuits of economic and social exchange that becomes a site of agrarian innovation. Through analysis of an original archive of popular posts collected from Myanmar-language Facebook (...) pages and groups related to agriculture, I explore the ways that farmers, traders, agronomists and agricultural companies use social media to further agrarian commerce and knowledge. These activities evidence that farmers use Facebook not only to exchange market or planting information, but also to interact in ways structured by existing social, political and economic relations. More broadly, my analysis builds on insights from STS and postcolonial computing to disrupt assumptions about the totalizing power of digital technologies and affirm the relevance of social media to agriculture, while inviting new research into the surprising, ambiguous relationships between small farmers and big tech.

This paper sets out to capture the emergence between 1760 and 1840 of a recognizable science of agriculture in Europe. The first attempts to explain and to theorize husbandry as practiced on the farm emanated from economists and agronomists employing the ‘encyclopedic’ approach of the Enlightenment generation. Despite significant additions to chemical knowledge in the late eighteenth and the early nineteenth centuries the task of applying this knowledge to agriculture initially appeared insurmountable. Only in the 1820s and the 1830s were (...) the obstacles gradually removed. A more rigorous approach to experimentation and to quantification evolved, and it was combined with investment in institutions seeking to educate landowners and farmers. As a result of these developments chemists secured pride-of-place above all other professionals in the management of agriculture as the primary food-producing sector of the economy. (shrink)

This article draws attention to several different practices of observation, manipulation, and experimentation with the surface of natural things. Beginning from the observation that the surfaces of natural things invited observation, manipulation, measurement, and re-configuration, with the promise to unveil the knowledge of depths, this article explores how practical knowledge about the surface of things and bodies led to new conceptions of nature and matter as composed of layers, corpuscles, and artificially reproducible solid parts in early modern Europe. This article (...) explores issues of knowledge production, and studies the ways in which material knowledge-making practices contributed to the habits of observing and experimenting with the surface of nature. By discussing three groups of cases in which nature was known by its surface and practice was mixed with theoretical appraisals of matter—surgeons, butchers, and food-cutters; gardeners and agronomists; and physicians—this article argues that “cognitive models” focusing on the description as well as the manipulation of natural surfaces informed both artisanal practices and natural philosophy, bridging the “high” and the “low” in the age of the “scientific revolution.”.

This essay asks why Chinese and North Vietnamese agricultural scientists in the 1950s and 1960s willingly adopted the Soviet agricultural sciences represented not only by agronomists Ivan Michurin and Trofim Lysenko but soil scientist Vasili Williams. The answer, I argue, is that they were fascinated by the promise of Soviet agrobiology that I conceptualize as a combination of dialectical materialism and voluntarist productivism: if one masters the interconnectivity between plants, microbes, organic and inorganic materials, and soil, one can overcome the (...) given biological and environmental limits, manipulate and optimize the material flow, and ceaselessly maximize agricultural production. Engaging the historiographical debate about Lysenkoism—which has mostly paid attention to the Euro-American cases, genetic controversies, and geopolitical specificities of each locale—as a global phenomenon, I shed fresh light on the understudied Chinese and North Vietnamese cases, the intersection between Lysenko’s theories and Williamsian soil science, and epistemic commonality across national differences.

We introduce a novel form of experimental knowledge that is the result of institutionally structured communication practices between farmers and university- and local community-based agronomists (agricultural extension specialists). This form of knowledge is exemplified in these communities’ uses of the concept of grower standard. Grower standard is a widely used but seldom discussed benchmark concept underpinning protocols used within agricultural experiments. It is not a one-size-fits-all standard but the product of local and active interactions between farmers and agricultural extension specialists. (...) Grower standard is in some ways similar to more familiar epistemic objects discussed in philosophy of experiment, such as controls or background conditions. However, we argue that grower standard is epistemically novel, due to how knowledge arising from it is coproduced by farmers and agricultural extension specialists. Further, in the United States, this knowledge coproduction is institutionally structured by federal legislature dating back to the 19th century. We use our analysis of grower standard to focus a discussion of the positionality of the coproducers as well as the epistemic products of this form of knowledge coproduction, and we explore the role extension work plays in shaping agricultural science more broadly.

With agriculture the primary driver of biodiversity loss, farmers are increasingly expected to produce environmental outcomes and protect biodiversity. However, lack of attention to the way farmers perceive native vegetation has resulted in conservation targets not being met. The Yorke Peninsula (YP), South Australia, is an agricultural landscape where 50% farmers perceived that long-term planning was for ≤ 30 years, not enough time to promote ecosystem conservation; (5) a lack of natural resource management information for farmers—as a result, farmers relied (...) on their own experience to manage vegetation. Furthermore, most farmers depended on agronomists, who generally had no stake in biodiversity conservation. We recommend that (1) the Local Council restore social capital by liaising with farmers to promote roadside vegetation (2) long-term farmer-led conservation action be established and supported by Government and industry acting as facilitators rather than project managers; (3) a change in policy and training promote the involvement of agronomists in conservation and its management on private properties; (4) all levels of Government develop schemes to demonstrate the tangible benefits of native vegetation as habitat for wildlife; (5) on-farm conservation be celebrated as successful farming.

The aim of this essay is to return to the genesis of the American agrarian myth in the eighteenth century, as a path to investigate the origins of the American national identity. This will be done by means of a comprehensive reassessment of St. John de Crèvecoeur, the Norman noble whose name is bound to the success of Letters from an American Farmer. His work contains the origins of the agrarian ideal as a peculiarly American phenomenon, prior to independence and (...) before Republican ideology placed agrarian democracy at its foundations, making the project of agrarian development and democratic participation inseparable one from another. A Frenchman who became American and then, after 25 years, French again, Crèvecoeur represents an ideal lens through which to analyse the hitherto insufficiently explored contribution of French economic culture to the creation of American national identity. As a multi-faceted figure whose richness has been dominated by his image as the author of a best-selling autobiographical novel, Crèvecoeur is here also seen as an agronomist who was no stranger to physiocracy and as a diplomat and French intellectual who always felt profoundly American. It was precisely this attachment to the land, seen as fundamental to the vision of a new and distinct form of peaceful cohabitation and democratic partnership, that became a political theme and an economic development project of the new nation and, as such, was a main plank of the agrarian ideology of Thomas Jefferson's Republicans.

In lieu of an abstract, here is a brief excerpt of the content:An Encounter with the Art and Science of MedicineAnonymous Five“Let Nothing Upset YouLet Nothing Frighten YouEverything is ChangingOnly God is Changeless”—St. Theresa of AvilaSt. Teresa’s prayer is on the front cover of each of four binders dedicated to storing insurance authorizations, studies, references, and reports about our daughter’s brain tumor treatment. They represent our experience, what we learned, the information we were given, and the information we sought out. (...) I kept them in case our daughter ever wanted to understand how my husband and I arrived at a decision for her treatment that was in direct opposition to the strong recommendation of her primary treatment team of physicians.On December 10, 2003, I received an urgent call from our daughter’s neurologist requesting that we meet with the doctor late that afternoon. For six months prior to that appointment, our daughter had been telling us about odd sensations with breathing, nausea, and balance. Sometimes she would seem extremely distressed for a short period of time or report that her friends told her about doing or saying things that didn’t make sense and that she didn’t remember. We consulted a series of physicians as her symptoms became steadily more intense and more prevalent. Our family practice physician referred us to an allergy specialist and a pulmonologist. There were a number of tests for allergies and lung problems. As the tests and treatments did not help, our daughter became increasingly unwilling to go to doctor’s appointments. My husband and I were confused and deeply concerned about the lack of progress. The next series of referrals included a gastroenterologist and a neurologist. The gastroenterologist suggested our daughter had partial–complex epilepsy, concurred with our plan to see a neurologist, and mentioned she should have an MRI.I remember the neurologist putting the MRI scans up, pointing to the large dark spot which he called a “large mass” (5 cm), that could be either a cluster of blood vessels or a neoplasm. He said his office had arranged for us to meet a neurosurgeon the following day. We all remember the same thing about that visit—the image of the large dark mass on the scan—and the neurologists flat, brisk tone. We met with the neuro-surgeon the next day. Her team was kind and sympathetic—she was positive, up beat and direct. She did not think this mass was blood vessels. She thought it was a large tumor that needed to be removed right away. Our daughters surgery was scheduled for the following Friday—December 19, 2003. She had turned 15 on November 5.Four and a half hours after our daughter was wheeled into the operating room, her surgeon told us they had removed 98% of the tumor. She said there was no cure, but there was a good prognosis based on the surgical outcome. Several days later, she called us and said she had more data, and it looked like the resection was closer to 90%. The first pathology report, a “first impression” directly after surgery, described our daughter’s tumor as an astrocytoma, probably high grade. Three weeks after surgery, we met with a panel of doctors—two oncologists and radiologist—who explained that based on the final pathology report, our daughter’s tumor was classified as an ependymoma, grade 2. We were dismayed. First, there had been the change in the estimated success of the resection and now a complete shift in both grade and tumor type.The team recommended radiation to follow her surgery, which they said was standard treatment. We began to try to inform ourselves about her tumor. Her father, an agronomist, did an extensive search in PubMed to evaluate and sort through the literature on low–grade gliomas and radiation. What he could find was inconclusive and grim. Most reports in the literature suggested at best delayed mortality at five years after radiation. [End Page E7] Meanwhile, our daughter went through a spinal MRI and the preparatory “fitting” of the mask to immobilize her head during radiation.E7I consulted with a friend who had worked as an EKG tech. She urged... (shrink)

This paper explores the role of regulation and legislation on influencing the development and diffusion of technologies and methods of crop production. To do this, the change in pesticide registration under European Regulation 1107/2009 ‘Placing Plant Protection Products on the Market’ was followed through the UK’s agricultural system of innovation. Fieldwork included: a series of interviews conducted with scientists, agronomists and industry organisations; a programme of visiting agricultural events; as well as sending an electronic survey to British potato growers. The (...) innovation system is noted to have made the legislation less restrictive than originally proposed. The most notable system response to the legislation is the adjustment of agrochemical company pesticide discovery strategy and their expansion into biologically derived treatments. There have also been other innovation responses: agricultural seed companies have been breeding in pathogen resistance in their cultivars; agricultural consultancies are prepared to recommend pathogen-resistant seeds; scientists are using the change as justification for adopting their solutions; the agricultural levy boards funded research into off-label pesticide uses; and producers, potato growers in particular, have been seeking advice, but not changing their growing practices.

From its very beginnings, this century has been under the sign of genetics. Indeed, it was in 1900 that the laws established by Mendel in the mid-nirieteenth century were rediscovered. In that same year, Landsteiner identified the first human blood typing, the ABO system. At that time, agronomists, eugenicists, and physicians were the principal agents of the development of genetics. The chromosome theory of heredity was asserted beginning in 1911; it was followed in the 1940s by the understanding of the (...) role of the gene in cellular metabolism, and in 1954 by the explanation of the structure of the DNA double helix. The pre-eminence of genetics was to increase through the second half of the century, particularly in the 1970s with the advent of genetic engineering. (shrink)

The paper deals with the transformation of plant breeding from an agricultural practice into an applied academic science in the late 19th and early 20th centuries Germany. The aim is to contribute to the ongoing debate about the relationship between science and technology. After a brief discussion of this debate the first part of the paper examines how pioneers of plant breeding developed their breeding methods and commercially successful varieties. The focus here is on the role of scientific concepts and (...) theories in the agricultural innovation process. The second part turns towards the strategies by which agronomists tried to establish plant breeding as an academic discipline and themselves as the new experts for breeding research and varietal development. Again, the focus is on the interplay of scientific theory and agricultural practice. It is argued that in order to better understand the transformation of plant breeding into an applied academic science we have to take different levels into account, i.e. the levels of organizations, individuals and objects, at which science and technology interact.

This paper analyses the use of metaphor in discourses around the “superweed” Palmer amaranth. Most weed scientists associated with the US public agricultural extension system dismiss the term superweed. However, together with the media, they indirectly encourage aggressive control practices by actively diffusing the framing of herbicide resistant Palmer amaranth as an existential threat that should be eradicated at any cost. We use argumentative discourse analysis to better understand this process. We analyze a corpus consisting of reports, policy briefs, and (...) press releases produced by state extension services, as well as articles from professional and popular magazines and newspapers quoting extension specialists and/or public sector weed scientists or agronomists. We show how the superweed discourse is powered by negative metaphors, and legitimizes aggressive steps to eradicate the weed. This discourse reinforces the farmers’ techno-optimism master frame, contributes to deskilling of farmers and sidelines ethical concerns. (shrink)

The aim of this work is to end the debate about the widespread acceptance among specialists, that the 6th century Byzantium treatise by Cassianus reached Muslim scholars by means of two routes: a translation from Greek into Arabic and the other translation by means of a Persian translation. Thanks to a comparison of the texts, one can prove beyond all doubt that there was only a secondary translation route into Arabic from the Persian version. Additionally, this work highlights the significant (...) influence of the Fila[hdotu]arumiyya on the Andalusian agronomy. The most influenced subjects are pointed out and those agronomic sources derived from this treatise and the 10th century Greek Geoponica are studied. This study allows us to conclude that the later work was never translated into Arabic, therefore, the Andalusian agronomists only had access to the Arabic versions of Anatolius and Cassianus to which the Pseudo-Qus[tdotu]us' work was later added.

This paper examines the history of Japanese genetics in the 1920s to 1950s as seen through the work of Hitoshi Kihara, a prominent wheat geneticist as well as a leader in the development of the discipline in Japan. As Kihara's career illustrates, Japanese genetics developed quickly in the early twentieth century through interactions with biologists outside Japan. The interactions, however, ceased due to the war in the late 1930s, and Japanese geneticists were mostly isolated from outside information until the late (...) 1940s. During the isolation in wartime and under the postwar U.S. Occupation, Kihara adapted to political changes. During wartime, he developed a research institute focusing on applied biology of various crops, which conformed to the national need to address food scarcity. After the war, he led the campaign for the establishment of a national institute of genetics and negotiated with American Occupation officers. The Americans viewed this Japanese effort with suspicion because of the rising popularity of the controversial theory of the Russian agronomist, Trofim Lysenko, in Japan. The institute was approved in 1949 partly because Kihara was able to bridge the gap between the American and Japanese sides. With Kihara's flexible and generous leadership, Japanese genetics steadily developed, survived the wartime, and recovered quickly in the postwar period. The article discusses Kihara's interest in cytoplasmic inheritance and his synthetic approach to genetics in this political context, and draws attention to the relation between Kihara's genetics and agricultural practice in Japan.

During the 1990s, the Government of Peru began to aggressivelyprivatize agriculture. The government stopped loaning money to farmers' cooperatives and closed the government rice-buying company. The government even rented out most of its researchstations and many senior scientists lost their jobs. As part of this trend, the government eliminated its seed certification agency. Instead, private seed certification committees were set up with USAID funding and technical advise from a US university. The committees were supposed to become self-financing (bycertifying seed grown (...) by small seed producers) and each committee was supposed to encourage the development of a group of small seed-producing firms, clustered around the seedcertification agency. The amazing thing is that many of the seed committees actually accomplished these goals. The agronomists who staffed the committees stood by their jobs,even after US funding ended, even though the committees' income was (at best) modest, and occasionally under the threat of violence from the extreme left. Some seed certificationcommittees failed and others did not. Some of the problems with Peruvian agricultural liberalization can be seen in regard to the seed programs of maize, rice, potatoes, and beans. For example, the government abandoned most research, yet could not resist creating certain distortions in the seed market (e.g.,buying large amounts of seed and distributing them for political ends).
