Expert systems for agriculture   总被引:1,自引:0,他引:1  
Recent advances in computer technology have been made possible the development of Expert Systems. Expert Systems are special computer software applications that are capable of carrying out reasoning and analysis functions in narrowly defined subject areas at proficiency levels approaching that of a human expert. The prime targets for the development of expert systems applications in agriculture are the narrowly defined subject areas which have experts available for solving problems. All commercial crop production systems in existance today are potential candidates for Expert Systems. These Expert Systems would take the form of integrated crop management decision aids which would encompass irrigation, nutritional problems and fertilization, weed control-cultivation and herbicide application, and insect control and insecticide and/or nematicide application. Additional subject areas of potential are plant pathology, salinity management, crop breeding, animal pathology, and animal herd management. The advantage of Expert Systems is that once developed they can raise the performance of the average worker to the level of an expert.  相似文献

The value of management information systems (MISs) arises from improved managerial decision making and, therefore, will vary from farm to farm. Insight into this variation will be of use not only to farmers who consider (new) MIS investments, but also to companies that design and market MISs. In this study, the impact of farm management on the value of sow-herd MISs is investigated. Within the same research population, farm management is assessed with two conceptually different classification approaches — the sociological ‘style of farming’ approach and the farm-economic ‘management level’ approach. Management levels of sow farmers turned out to be positively correlated with MIS value (r=0.35, P=0.02). Although farmers with high management levels tend to be better informed anyway than farmers with low management levels, they get more added value from MISs.  相似文献

The agricultural communicator is a key link in transmitting information to farmers. If agricultural communicators' ethics are compromised, the resulting biases in news production could have serious detrimental effects on the quality of information conveyed to farmers. But, to date, agricultural communicators' perceptions of ethical problems they encounter at work has not been examined. This study looks at the dimensions of ethical concerns for topics area (agricultural) journalists as defined by practitioners. To determine these dimensions, we sent open ended questionnaires (50 percent response rate) to members of two professional agricultural journalist associations: the Newspaper Farm Editors of America and the American Agricultural Editors' Association. Agricultural communicators overwhelmingly focus on one specific threat to objectivity—advertising pressure. Both NFEA and AAEA respondents indicated that agricultural journalists' responses to advertising pressure adversely affected the entire profession. The responses indicated that agricultural writers were concerned with the different types of pressures and the effects of advertising pressure on the industry as a whole. NFEA and AAEA respondents mentioned both indirect pressure, “freebies,” conferences, trips and press releases from advertising or public relations sections of agri-business firms, and direct pressures from advertisers, salesmen and publishers. The respondents were clearly more comfortable when newspaper policy protected them from advertising pressure and when they had techniques to reduce this pressure. The editors' and reporters' perceptions of advertising pressure clearly indicates that advertising abuses are a clear and present danger and one worthy of far more attention than it has previously received.  相似文献

Our aspirations are pessimistic for the fast diffusion of complex and demanding information technology (IT) aids and decision support systems (DSSs) among farmers. This view arises from some results of the new institutional economics, recent results of empirical decision research, data from farmers applications of decision models, as well as experiences introducing farm-level DSSs by our own working group at Giessen. For some areas of decision making, one can only hope that the use of models heightens problem awareness by the user, thus providing additional insights into the usually complex decision space. If, however, farmers want to increase the economic efficiency of their production and marketing processes by decreasing waste and friction, then we must continue to develop and refine knowledge-based DSSs. Problem selection, however, should be driven by new results of empirical decision research. Because imperfect knowledge exists regarding the input–output relations of agricultural production systems, as well as about the time- and space-variant uncontrollable input variables, close co-operation with the biological disciplines of agricultural science is needed. Multi-disciplinary research and end user orientation seem to be the key factors for further progress.  相似文献

Much of the attention by social scientists to the rapidly growing organic agriculture sector focuses on the benefits it provides to consumers (in the form of pesticide-free foods) and to farmers (in the form of price premiums). By contrast, there has been little discussion or research about the implications of the boom in organic agriculture for farmworkers on organic farms. In this paper, we ask the question: From the perspective of organic farmers, does “certified organic” agriculture encompass a commitment to “sustainability” that prioritizes social goals? Specifically, we aim to broaden our understanding of the relationship between social sustainability and organic agriculture by drawing attention to issues affecting farmworkers, whose labor and contribution tends to elude most discussions of organic agriculture. We present findings from a survey of organic farmers in California about the possible incorporation of social standards into organic certification criteria. Our findings suggest that, at best, lukewarm support for social certification within organic agriculture exists among certified organic farmers in California. They also question expectations that organic agriculture necessarily fosters social or even economic sustainability for most of the farmers and farmworkers involved. However, we also find exceptions to the patterns evidenced in our survey. In-depth interviews with select organic farmers demonstrate that there are individuals whose practices are atypical and demonstrate that, under some circumstances, an organic production system can be at once environmentally, economically, and socially sustainable.  相似文献

Although the microcomputer has significant potential for enhancing farm decisionmaking, implementation of that innovation must occur within the framework of each farm's information system. In this paper the concept of alternative information networks is suggested for industrial stage versus information stage farms. Evidence is presented that suggests that a movement from industrial stage farms is occurring. Implications of such a movement for farm adoption of computers are discussed.  相似文献

The role of RFID in agriculture: Applications, limitations and challenges   总被引:2,自引:0,他引:2  
The recent advances in RFID offer vast opportunities for research, development and innovation in agriculture. The aim of this paper is to give readers a comprehensive view of current applications and new possibilities, but also explain the limitations and challenges of this technology.RFID has been used for years in animal identification and tracking, being a common practice in many farms. Also it has been used in the food chain for traceability control. The implementation of sensors in tags, make possible to monitor the cold chain of perishable food products and the development of new applications in fields like environmental monitoring, irrigation, specialty crops and farm machinery.However, it is not all advantages. There are also challenges and limitations that should be faced in the next years. The operation in harsh environments, with dirt, extreme temperatures; the huge volume of data that are difficult to manage; the need of longer reading ranges, due to the reduction of signal strength due to propagation in crop canopy; the behavior of the different frequencies, understanding what is the right one for each application; the diversity of the standards and the level of granularity are some of them.  相似文献

Interviews with Community Supported Agriculture (CSA) growers in Iowa, a majority of whom are women, shed light on the relationship between gender and CSA as a system of resource management. Growers, male and female alike, are differentiated by care and caring-practices. Care-practices, historically associated with women, place priority on local context and relationships. The concern of these growers for community, nature, land, water, soil, and other resources is manifest in care-motives and care-practices. Their specific mix of motives differs: providing safe and nutritious food, educating self and others, and building relationships with other growers, shareholder-members, and the land. Care-practices include reducing or eliminating chemical usage, encouraging or accepting beneficial insects and wildlife, building soil, and creating resource management partnerships with shareholder members. CSA, viewed through a lens of care, may offer a means of transcending gender stereotypes. This revised version was published online in June 2006 with corrections to the Cover Date.  相似文献
