17 pages, The purpose of the study was to design a device for the dissolution of fertilizers for agricultural use in an automatic and environmentally sustainable way to facilitate the work of farmers. To achieve this goal, an outdated blade design was used, which generates turbulent and laminar flows thanks to the angle of inclination of its blades. In tests, the combination of these two flows gave a better result compared to laminar and turbulent flows separately. The best results were achieved by varying the spin and speed, the time between spins, and the rest time. The time it would take to dissolve the mixture was drastically reduced if it were conducted in the traditional way (manually) or compared with commercial mixers. In conclusion, the technique used for the dissolution of agricultural minerals is more effective and reduces time, energy, and effort. This was able to reduce the time necessary to dissolve the fertilizer by 93 percent compared to doing it manually and by 66 percent compared to using commercial mixers, in a solution of 100 L of water per 100 kg of ammonium sulfate.
7 pages., ebook ISBN 978-3-319-90835-9, Via ebook chapter., The article studies the main reasons for low level of information provision of agricultural production, including the absence of legal documents on systemic development of informatization; imperfection of applied forms and methods of operative planning and regulation of technological processes in most agricultural organizations; unpreparedness of most managers and specialists in agriculture in the sphere of effective usage of scientific methods for managing production processes. The offers for creation of a single three-level automated information and management system are given; it is an initial and necessary condition for improvement of management of agricultural production, improvement of organizational and economic mechanism of management of production processes in the sphere, and implementation of digital economy. Besides, two variants of development of informatization in agricultural production are provided. The first one is the classic variant, based on studying the management object, design of its tasks and functions, and the second is based on creation of a three-level information system of managing the system in the country’s regions.
28pgs, Technological advancement is seen as one way of sustainably intensifying agriculture. Scholars argue that innovation needs to be responsible, but it is difficult to anticipate the consequences of the ‘fourth agricultural revolution’ without a clear sense of which technologies are included and excluded. The major aims of this article were to investigate which technologies are being associated with the fourth agricultural revolution, as well as to understand how this revolution is being perceived, whether positive or negative consequences are given equal attention, and what type of impacts are anticipated. To this end, we undertook a content analysis of UK media and policy documents alongside interviews of farmers and advisers. We found that the fourth agricultural revolution is associated with emergent, game-changing technologies, at least in media and policy documents. In these sources, the benefits to productivity and the environment were prioritised with less attention to social consequences, but impacts were overwhelmingly presented positively. Farmers and advisers experienced many benefits of technologies and some predicted higher-tech futures. It was clear, however, that technologies create a number of negative consequences. We reflect on these findings and provide advice to policy-makers about how to interrogate the benefits, opportunities, and risks afforded by agricultural technologies.
