INTELIGENT SYSTEMS USED IN MODERN AGRICULTURE

Digital agriculture is the perfect integration of digital technologies in crop and animal management and other agricultural processes. For farmers, digital farming offers the opportunity to increase production, save long-term costs and eliminate risk. Agricultural researchers see it as a data collection tool that has the ability to simplify data collection and analysis, improving predictive skills when it comes to crop management, animal behavior and production. A digital agricultural system is a database that includes not only different types of data relevant to agriculture, from soil conditions to market assessment, but also optimal decision-making functions that help to take the best measures in a series of processes. The paper presents a brief summary of new technologies in agriculture

ASPECTS REGARDING THE OBJECTIVES, PRINCIPLES AND NORMS OF ORGANIC AGRICULTURE

Organic farming can be defined as a production system that broadly avoids or excludes the use of synthetic compound fertilizers, pesticides, growth regulators and feed additives. Organic farming systems are based on crop rotation, the use of crop residues, animal manure or off-farm organic waste.This article presents the advantages and importance of this system of agriculture, by analyzing the objectives, principles and rules of organic farming, in the context of the high needs of the population to consume organic products

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

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

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

RESEARCH ON THE IMPLEMENTATION OF INDUSTRY 4.0 IN INTEGRATED MANUFACTURING SYSTEMS

In the context of Industry 4.0, manufacturing systems are being upgraded to a smart level. Intelligent manufacturing takes advantage of advanced technologies, information and manufacturing to achieve flexible, intelligent and reconfigurable manufacturing processes in order to address a dynamic and global market. It allows all physical processes and information flows to be available, when and where they are needed across supply chains, multiple industries, small and medium enterprises (SMEs) and large companies. Smart manufacturing requires certain core technologies to activate devices or machines in order to vary their behaviors in response to different situations and requirements based on past experiences and learning abilities. The technologies allow direct communication with the production, thus allowing the solution and adaptation of problems and decisions that must be taken in a timely manner

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

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

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

CONSIDERATIONS REGARDING THE IMPORTANCE OF THE SORTING OPERATION OF FRUITS AND VEGETABLES

For the normal development of daily activity and maintaining health, the body needs a certain amount of energy and complete nutritional factors (proteins, carbohydrates, lipids, vitamins, minerals, water). They are obtained from food, fruits and vegetables occupying a prominent place as a natural source of carbohydrates, alkalizing mineral salts, vitamins and water. Conditioning involves a set of operations aimed at bringing the products to the characteristics provided by standards, specific to a certain direction of capitalization. This article describes the operations included in the conditioning process, the role and importance of presorting and sorting fruits and vegetables, as well as equipment for these operations
