THE USE OF DRONES IN MODERN AGRICULTURE

Drones are largely associated with military, industrial and other specialized operations, but with recent developments in sensors and information technology over the past two decades, the scope of drones has been expanded to other areas, such as agriculture. This approach to agricultural management is based on the observation, measurement and measurement of real-time data on crops and animals. It removes the need for assumptions in modern agriculture and instead gives farmers the ability to maximize their yields while increasing crop production. This paper presents a brief summary of drone implementation in agriculture

ALGAE COMPOSTING AND THE USE OF COMPOST OBTAINED AS FERTILIZER FOR ORGANIC FARMING

Composting is a cheap and efficient management approach for recycling organic waste, but also an alternative to landfills. Recycling algae into composts has also proven to be an ecological alternative for reducing beach pollution and water eutrophication. There is a growing interest in the use of algae-based fertilizers as they maintain organic farming and contribute to a significant increase in agricultural productivity. This paper presents the particularities of algae as a raw material for composting, the types of composting methods, as well as the advantages and disadvantages of algaebased fertilizers in terms of agricultural cultivation

USE OF AQUATIC PLANTS PISTIA STRATIOTES, EICHHORNIA CRASSIPES AND SALVINIA MOLESTA AS ORGANIC FERTILIZER IN SUSTAINABLE AGRICULTURE – REVIEW

The intensive application of pesticides and chemical fertilizers, in the context of the continuous development of agriculture, has led to a high level of environmental pollution and a serious deterioration in soil fertility. In an attempt to reduce all these negative effects, classical agriculture is moving towards sustainable agriculture. An ecological alternative to the use of chemicals is the application of organic fertilizers. One of the ecological sources is aquatic plants. Often considered invasive due to their rapid development, aquatic plants have a real potential in sustainable agriculture. This review presents the use of aquatic plants pistia stratiotes, eichhornia crassipes and salvinia molesta as organic fertilizer in sustainable agriculture

AGRICULTURE 5.0 - REVIEW

Agriculture has always been an area of great interest when it comes to development and innovation. We are currently living in the age of agriculture 4.0 which is on the rise. That is why we will reach agriculture 5.0 which will be marked by the introduction of artificial intelligence,biotechnology and big data analysis, which will increase the performance, productivity and accuracy of automation

INTELLIGENT WIRELESS TECHNOLOGY USAGE EFFECT IN CONTEXT OF PHYTOSANITARY TREATMENT SPRAYING

In agriculture, pesticides and fertilizers are applied to prevent crop disease and increase plant productivity. As a result of the digitalization of agriculture, human labor is increasingly interacting with intelligent technology through robots to facilitate agricultural operations. The use of intelligent technology protects the natural ecosystem by reducing the major damage caused by the unconventional application of phytosanitary treatments resulting in a flexible, proportional spraying at precise angles, thus avoiding the generation of large amounts of chemicals. This paper presents a short review about the state of the art of wireless sensors networks and how together with robotics can be applied in different fields of agriculture through the prism of sprayers that include a detection system and a wireless controlled spraye

CULTIVATION TECHNOLOGY AND BENEFITS OF FENUGREEK

Fenugreek (Trigonella foenum-graecum L.) is a plant native to the Mediterranean region. The name of the species means "Greek hay" because in the past it was used as a forage plant, another use being that of spice or medicinal plant throughout the world. Fenugreek is one of the oldest medicinal plants, having positive effects on antidiabetic, anticarcinogen, hypocholesterolemic, antioxidant and immunological activities, can also be used as a green fertilizer, enriching the soil with nutrients. This paper aims to describe the technology of cultivating fenugreek, but also to highlight its main benefits

ASPECTS ON THE CONSTRUCTION AND OPERATION OF SPRAYING EQUIPMENT FOR REDUCING DRIFT IN FIELD CROPS

The paper presents innovative solutions on the construction si operation of spraying machines in the view of reducing drift in field crops: with innovative electrostatic spraying system, with special panels with static condenser, nozzle protection system, spraying devices provided with hoods, downward air curtain system and with shielded system with caps for controlling drop dispersion. The paper is important, on the one hand, for producers of spraying equipment for reducing drift and, on the other hand, for farmers in the view of efficiently applying treatments in field crops, but also for reducing environmental pollution

RESEARCH REGARDING THE EQUIPMENT USED IN WATER TREATMENT PROCESSES OF RECIRCULATING AQUACULTURE SYSTEMS

Modern aquaculture technologies are made with the help of recirculation systems, which require the use of innovative and high-performance solutions for the treatment of recirculated water. Aquaculture recirculation is essentially a technology for growing and developing fish or other aquatic organisms by reusing water for more intensive fish production. The technology is based on the use of mechanical and biological filters, and this ecological method can be implemented for any species cultivated in aquaculture, such as fish, shrimp, mussels, etc. The scientific paper presents a brief summary of the control and solution of the main problems faced by water recirculation systems

Clinical Experience and Examination Performance: Is There a Correlation?

Context  The Liaison Committee on Medical Education (LCME) requires there to be: ‘…comparable educational experiences and equivalent methods of evaluation across all alternative instructional sites within a given discipline’. It is an LCME accreditation requirement that students encounter similar numbers of patients with similar diagnoses. However, previous empirical studies have not shown a correlation between the numbers of patients seen by students and performance on multiple-choice examinations. Objective  This study examined whether student exposure to patients with specific diagnoses predicts performance on multiple-choice examination questions pertaining to those diagnoses. Methods  The Department of Pediatrics at the University of Nebraska Medical Center has collected patient logbooks from clerks since 1994. These contain information on patient demographics and students\u27 roles in patient care. During week 7 of an 8-week course, students took an examination intended to help them prepare for their final examination. Logbooks and pre-examination questions were coded using standard ICD-9 codes. Data were analysed using Minitab statistical software to determine dependence between patient encounters and test scores. Subjects comprised a convenience sample of students who completed the clerkship during 1997−2000. Results  Our analysis indicates that performance on a multiple-choice examination is independent of the number of patients seen. Conclusions  Our data suggest knowledge-based examination performance cannot be predicted by the volume of patients seen. Therefore, too much emphasis on examination performance in clinical courses should be carefully weighed against clinical performance to determine the successful completion of clerkships

IMPACT OF GRANULAR FLOW DYNAMICS ON THE DESIGN AND MODELLING OF THE BUNKERS

Silos and bunkers are widely used in the storage, storage and distribution of granular materials, of particular importance in the management of handling, transport and conditioning operations. The distribution of seeds at the filling and emptying stage of the bunker examines the main loading and unloading hypotheses leading to different limit states for its structure. This paper will present the results of causes such as the maximum pressure perpendicular to the vertical wall of the silo, the maximum stretching effort due to friction with the vertical wall, the vertical pressure on the basis of it and the maximum load on the bunker funnel, resulting in the implementation of new design and modeling solutions. At the same time, the dynamics of the granular flow in the bunkers, including flow regimes, design and optimal shapes, will be described to avoid the loss of energy generated by the collision of macroscopic particles inside it
