A flight of a UAV formation is an efficient way to implement surveillance and reconnaissance operations. The usage of a few UAVs as a formation instead of a single vehicle allows creating a distributed network of sensors, which decreases the duration of flight missions and enlarges a total field of view. From a practical point of view, implementations of formation flights require taking into account...
Consumers increasingly appreciate high quality and nutritional value of organic products. Therefore distribution network is growing, organic food is offered by all sorts of shopping centers and online stores. The aim of the study was to analyze and evaluate the range of organic food of Polish and foreign origin available in select retail locations in Warsaw, and online stores. Results show that the...
Berries belong to the best dietary sources of bioactive compounds, mainly phenolic compounds (phenolic acids, flavonoids including anthocyanins and flavonols, tannins) and vitamin C (ascorbic acid). These compounds, either individually or combined, are responsible for various health benefits of berries, in that protective effects to lower the risk of various cancers. Over the last 25 years, a significant...
The fruits of the old cultivars are valuable because of the taste and their culinary usefulness. The old cultivars of plants increase biodiversity in organic farms. Plum fruits are characterized by high healthy potential because they are rich in numerous biologically active compounds (polyphenols, especially phenolic acids, flavonoids and anthocyans), as well as vitamin C. In the presented work the...
The organic food sector is one of the most dynamically developing food sector branches nowadays. Increased interest in organic food production and consumption is a response to the growing negative effects of agriculture intensification, which has contributed to environmental degradation and reduced food safety. The aim of the study was to identify and analyse the strengths and weaknesses, as well...
The aim of this paper was to analyze the Polish stakeholders from the organic sector in terms of their expectations towards the potential employees and to evaluate what kinds of the professional knowledge and skills are expected by the employers.

Nowadays nearly 40% of Earth’s land is used by agriculture. Large areas of arable land are covered by cash crops monocultures, and most common intensive agricultural practices are highly dependent on water, synthetic mineral fertilizers, chemical pesticides, and increasingly also on the products of genetic engineering. The mentioned means of agricultural production, aiming at maximizing yields while...
Four species of leafy vegetables from organic and conventional production (coriander, leaf mustard, rocket salad and watercress) were used in this experiment. The research material consisted of edible parts of vegetables harvested in the beginning of September 2015. After harvest, dry matter content of plant samples was determined. Then plant material was freezedried and stored at -80oC until further...
The quality of the organically produced fruit and vegetables is a frequent subject of research, but very few authors have investigated the differences in the content of biologically active compounds in organic agricultural crops depending on the age of the organic farms. At the same time, many studies have shown that the soil and the whole agroecosystems need time to stabilize after conversion of...
The purpose of this study was to evaluate and compare the environmental awareness of the organic and conventional farmers on the territory of the Podlaskie voivodeship.

These prerequisites prompt organic producers to look for new solutions and bring an increasingly broad...
The presented study gives an overview of recently published research investigating the health value of organic foods. Some in vitro studies indicated higher antimutagenic and antioxidant activity, as well as more effective inhibition of cancer cell proliferation by organic compared to conventional foods. Most of the well-designed animal model experiments carried out so far have demonstrated significant...
