From year to year, there is an increasing demand for agricultural produce from certified organic farms. However, Poland and Hungary’s demand for this product is almost twenty times smaller than in Western European countries. The greater the demand by consumers for organic farming products, the more agricultural producers decide to switch from conventional farming to organic farming, and this farming is more environmentally friendly because it uses energy and natural resources responsibly, maintains biodiversity, maintains regional ecological balance, improves soil food, and maintains good water quality. This research aimed to compare the motives and barriers to running organic farms in Poland and Hungary, and the challenges farmers must face to undertake the trouble of running an organic farm. The research was carried out among 400 Polish and 400 Hungarian farmers running organic farms. For statistical calculations, discriminant analysis, as well as single-base and chain indices, were used. The main barriers for establishing organic farms: the necessity to adapt one’s farm to the EU requirements, using only natural fertilizers, low yields, the lack of proper advice, and a high degree of bureaucracy. Therefore, for organic farming to develop, further education is needed, both for farmers and consumers. An important aspect is improving the quality of the regulations and simplifying the administrative burden related to organic farming.

Soil plays a key role in sustainable land management and food production. The objective of the field experiment was to evaluate the subsequent effect of 10-year winter wheat and sugar beet cultivation under conventional and organic systems on selected physicochemical and biochemical properties and enzymatic pH index of lessive soil developed from loess under climatic conditions of Southeastern Poland. The experiment was set up by using the split-plot design, with three replications, on plots of 30 m2. In order to evaluate the soil value of sites cultivated in 2010–2019 in two systems—conventional agriculture and organic agriculture—spring wheat was sown as a test crop in 2020. Fertilization and pesticide applications (herbicides, fungicides and insecticides) were foregone in the cultivation of this crop due to the desire to capture the subsequent impact of 2010–2019. This resulted in soil properties shaped solely by the previous 10 years of cultivation. The obtained results indicate that the organic farming system contributed to the improvement of soil pHKCl compared to the conventional system, with statistically significant differences recorded only for winter wheat cultivation. Compared to the conventional system, in the organic farming system, improvements were recorded in the chemical indicators of loess soil quality (TOC, TN and TOC/TN) and P content, as well as acid phosphatase and alkaline phosphatase activities. However, statistically significant differences were found only for winter wheat cultivation. Research on the impact of an organic system of growing different species in rotation should be continued, and the results should be implemented.

Post-mining areas require reclamation. The main aim of reclamation is to restore the soil as a basic element of the terrestrial ecosystem. This paper presents the results of an evaluation of the enzymatic activity of soils formed on an afforested heap from an opencast sulphur mine. Six research sites were selected on the overburden heap of the Piaseczno sulphur mine, afforested 50 years ago. They differed in the type of soil in the subsoil and in the species composition of the stand. The activity of dehydrogenases, phosphatases, urease, total organic carbon, and total nitrogen was determined and statistical analysis of the obtained results showed that the activity of the evaluated enzymes in the soils formed in the reclaimed areas was significantly dependent on the type of substrate and the species composition of the plants. The activity of the evaluated enzymes was significantly positively correlated with the content of total nitrogen and the C/N ratio, and the activity of phosphatases and urease with the total organic carbon content. Within soils developed on the same texture, the influence of stand species was revealed. In soils formed on clay, the soils under the beech stand and under the birch stand were characterized by higher activity of enzymes. The soil developing under the stands of European larch and red oak was characterized by higher enzymatic activity on weakly clayey sands. On loose sands, the activity of dehydrogenases and urease was significantly higher under acacia robinia than under hornbeam.

Purpose The purpose of this paper is to assess nutritional habits and body composition parameters in the group of Polish pupils and students. Design/methodology/approach The study was conducted by the body composition analysis using the biological impedance method applying TANITA analyzer and diagnostic survey method using standardized direct interview with selected elements of the Sarzynska test. The research was carried out in various regions of Poland on a group of 1,000 pupils and students, using a targeted sample selection in the following subgroups: 250 middle school pupils, 250 high school students, 250 students living in a family home and 250 students living in an academic home. Findings Significantly the worst nutritional habits according to the Sarzynska test are shown by students living in academic home. As many as 21.6 percent of them eat very badly, while only 10.4 percent of students living in a family home eat very badly. This may indicate a lack of conditions, skills and time to prepare healthy meals, but also the lack of parental control in relation to what their child eats. The middle school pupils eat the healthiest meals (64.4 percent). It can be seen the regularity that the older the child is, the smaller the percentage of people in the healthy group. Research limitations/implications A research limitation was the little sample size of the study (1,000 person) and participants might have felt uncomfortable during research. Practical implications People planning class schedules should also plan breaks for a full-value meal. It is necessary to organize affordable courses that would teach simple and fast food preparation that does not require a lot of equipment and little popular ingredients. It would also be necessary to draw parents’ attention to excessive care and the fact that not allowing children to “experiment” in the kitchen may arouse in them the reluctance and fear of cooking. Social implications Among students, one should conduct universal education regarding a healthy lifestyle, which should focus on the subject of proper nutrition and physical activity, because there are no systemic solutions that would include adults. In order to improve nutritional habits, social rooms in academic homes should be adjusted so that students have the conditions to prepare nutritious meals, as well as provide access to canteens, where students would receive a reasonable meal at a reasonable price. The qualifications of the staff working there should also be improved. Originality/value The present study adds to the existing body of literature nutritional habits and body composition parameters in the group of Polish pupils and students. The results are the foundation for providing recommendations to policy makers, universitets, schools, food organizations and parents.

Corporate social responsibility (CSR) assumes that companies should justify their existence with services for various stakeholders and not with profit alone. There is a strong emphasis on the implications of CSR for managing human resources in hotels and other accommodation services, supporting local communities, and promoting environmental sustainability. This article aims to present the adjustment of business entities providing accommodation services in Poland to the CSR principles. Two aspects were examined: the environmental aspect, i.e., waste segregation and the use of economic energy receivers, while the social aspect included engaging employees, as well as investing in improving their qualifications towards pro-ecological awareness. The study was conducted on a sample of 207 owners and managers of economic entities in the accommodation sector in Poland. The Statistica software was used to analyze the obtained results, including Chi2 statistics and correspondence analysis. Based on the obtained results, it can be concluded that the employees of accommodation centers usually deal with the final segregation of waste because they believe that tourists do not follow the rules of proper segregation. Most hotels are equipped with bins for all fractions of waste. The affiliation of a center to a specific macroregion in Poland was not statistically significant in terms of waste segregation practices. Only in the southern macroregion of Poland, ordinary light bulbs are used in accommodation establishments, which account for 0.97% of the surveyed population. In other regions, ¾ establishments use energy-saving receivers in all rooms. Only 1/3 of the facilities invested in developing their staff by organizing training courses toward sustainable development. The most popular subjects were topics related to waste segregation, energy and water saving, and environmental protection.
