The energy crisis in Europe and Poland caused by the conflict in Ukraine has renewed the debate in some countries about the wisdom of abandoning the use of local fossil fuels. The rise in gas and oil prices with little change in the cost of extracting lignite from open pit mines has led to a renewed consideration of lignite as the cheapest source of energy. This is not entirely true, as the level of costs at power plants ignores many external costs that are not included in the costs of energy producers, but are borne by the general public or other parties. One such cost is the external costs incurred by agriculture as a result of open pit lignite mining and the associated depression funnels. The Bełchatów lignite open pit is the deepest open pit in Europe and is expected to be in operation by 2038. The aim of the study was to assess the external costs that farmers will incur as a result of further open pit mining of brown call from the Bełchatów deposit, i.e., between 2023 and 2038 ...

Health claims increase consumer awareness, knowledge, and health consciousness. However, front and back labels, which are widely used for marketing purposes, raise doubts about consumer tendencies towards paying attention to health claims and reasons for their placement. Therefore, the aim of this article is to investigate, using the Theory of Planned Behaviour, the extent to which intention to pay attention to health claims is determined by its predictors. An extended model based on the theory was used to identify factors that shape attitudes towards health claims and the intention to pay attention to them. In order to achieve this, we conducted a study on 552 people, and the data allowed us to verify the statistically proposed theoretical model. The study revealed that while trust is the main factor determining attitude towards health claims, the impact of subjective knowledge is negative. Research is important from the perspective of the theoretical understanding of consumer atti...

The aim of the study was to assess regional changes in pig and sow population in 2010-2022. The analysis was carried out at the voivodship level for the entire period under study, while changes in pig and sow population in poviats were based on agricultural census data for 2010 and 2020. The analysis showed a progressive regional concentration of pig and sow stock in Poland, as indicated by an increase in the share of the 62 and 93 poviats with the highest stock and the poviats with the highest density of pigs and sows using 20% and 30% of agricultural land in Poland by about 9 percentage points. However, there was no correlation of the level of pig and sow stocking in 2010 in individual poviats with changes in stocking rates by 2020. A large increase in stocking rates associated with the construction of industrial piggeries was recorded in a dozen poviats located mainly in the western and northern voivodships, where the largest number of State Agricultural Farms were located.

In many circles, including in Poland, lignite is still viewed as a cheap source of energy, which is only possible if the external costs associated with mining and burning coal are not taken into account. In Poland, this is reflected in plans to open new Złoczew opencast lignite mines. In previous studies, the analysis of external costs has focused on the external costs of coal combustion and related pollutant emissions. This paper focuses on the extraction phase. The aim of the work here described was to estimate the external costs that agriculture may incur due to the formation of a depression funnel for the projected lignite mine in the Złoczew deposit. This paper discusses factors causing uncertainty in calculated estimates of external costs in agriculture, and characterizes the Bełchatów and Złoczew opencast mines. In the paper, a methodology for calculating external costs in livestock production is then proposed. In the next part of the study, the decrease in cereal and potato ...

The material used in the study concerns 60 farms from the Wielkopolska region. They were divided depending on a degree of the farm integration with the slaughterhouses and on a scale of pigs production. The analyses include calculations of pigs prices, costs of pigs production and profits obtained by the farmers. Besides, the objects of the research are the main pigs production costs (feed and labour) as well as investments realised in the investigated farms.

This article presents selected issues related to the problem of organizational culture. The work is based on the results of empirical research involving qualitative investigations using the case study method. It examines the values and norms defi ning the organizational culture of selected agricultural enterprises. It was found that the values and norms are an important factor in the competitiveness of a company. Appropriate shaping of the organizational culture promotes proinnovative behavior of employees and builds an attractive image of the organization. Considerations related to the culture of the organization revealed the importance of the multidimensionality of this concept. In addition, organizational culture can have a big impact on functioning and effectiveness of a company.

Abstrakt. W pracy została przedstawiona analiza komparatywna zmian w poziomie nakładów energetycznych w produkcji roślinnej w wybranych gospodarstwach rolnych w latach 2001, 2009 i 2010. Analiza wskazuje na duże zróżnicowanie nakładów energetycznych w poszczególnych gospodarstwach. W badanym okresie poziom tych nakładów na 1 ha w produkcji zbóż nie uległ zmianie (choć w przypadku poszczególnych gatunków zbóż nakłady zmieniły się od –20% do +48%), podczas gdy w przypadku buraków cukrowych nakłady te spadły nawet o ponad 50%. Po przeliczeniu nakładów energetycznych na 1 tonę zebranych płodów rolnych nakłady energetyczne – z wyjątkiem kukurydzy kiszonkowej – spadły w ciągu 9 lat od 6% (łąki) do 27-32% (zboża i ziemniaki), a w przypadku buraków cukrowych aż o 68%.

The study presents principles of integration of processing plants with agricultural sector producers in Poland, based on the dairy and meat industries 1 . In this aspect the goal of integration was presented along with its principles and popularity, both in the period of centrally planned economy and free market economy. At present processing plants in Poland with an increasing frequency develop cooperation with raw material producers on the basis of supply contracts. The highest degree of integration between meat plants and farmers is found in case of white meat producers. On the basis of pig production the effect of vertical integration on the profitability of this type of production in Poland in the period 2001 - 2006 was thoroughly analyzed and assessed, with special emphasis on benefits for these agricultural sector producers. For this purpose the study presents results of analyses conducted on a group of 60 pig producers producing minimum 200 fatteners annually. The analysis s...

The aim of the study was a regional analysis of changes in the population and stock of pigs in the years 1960-2015 at the voivodship level and in the years 1996-2010 at the district level. The analysis at the voivodship level was divided into two periods, which indicated the acceleration of polarization of the stock level in Poland. This is indicated by the growing share of voivodships and districts with the highest population and stock of pig in total population.

The aim of this study is a comparative analysis of the costs of production of intensively and extensively fed porkers in view of the qualitative parameters of meat obtained after slaughter. The production experiment, which involved the parallel fattening of 3 groups of 30 porkers (fed intensively up to a weight of about 120 kg and extensively up to weights of about 100 kg and 120 kg), was carried out between 2011 and 2012 in a deliberately selected farm. The researchers assumed average prices of the means of production and prices of livestock pigs in individual meatiness classes noted in Poland in 2012. The fattening started when the animals weighed about 40 kg. The feeds used for extensive fattening contained less total protein, energy and basic exogenous amino acids, but more raw fibre. The analysis proved that the extensive production of porkers up to 100 kg in 2012 was not profitable. The most profitable production was the intensive production up to 120 kg (a profit of €0.100 pe...

Food product attributes may significantly influence the general perception of the product itself, as well as the willingness for its consumption. Assessment of the product is based on customers’ beliefs and individual preferences. Because meat-like products are presented as meat substitutes providing sufficient protein values, the present study aimed to determine the effect of protein source and labelling pointing at high protein content on the evaluation of the product. The experimental online study was conducted with a group of 552 respondents. Four versions of product packaging were designed and tested. These packages differed in the presence or absence of the Nutrition Claim and the presence of the text indicating the vegetable or meat origin of the product. Data collected in the experiment were analyzed using a 2 × 2 ANOVA. The study revealed that the source of protein (plant vs. animal) appears to shape consumers’ perception of the product as more eco-friendly (F (1.518) = 38....

The aim of the analysis was to determine changes in the level of spatial concentration of production in Poland in the years 1990-2020. The analysis includes output and commodity production, the production of basic agricultural raw materials, the livestock of cattle, cows, pigs, hens and animals converted to LU, and changes in the level of yield and milk yield of cows. The study used data from the Central Statistical Office and the Local Data Bank. In order to limit short-term variability, especially in crop production, five-year averages for the beginning and end of the period were used in most of the analyses. The analysis was carried out for the currently binding administrative division including 16 voivodships. The research has shown large changes in the spatial distribution of agricultural production in Poland. First of all, the Wielkopolskie Voivodship gained in the production of agricultural raw materials, as it increased its share in the majority of plant and animal agricultu...

The aim of the study was the analysis the energy expenditures incurred in the production of sorghum silage. Data wasobtained from card`s technological developed for the model farms producing crops for energy purposes. They were developed for farms located in 5 macro-regions. The analysis showed that the lowest energy consumption was characterized by the production of farms with an area of 130 ha, both per hectare and per ton of silage obtained. In case of regional analysis, it was found that the main determinant of energy expenditure were obtained yields. Regions obtaining the highest yields of sorghum had the highest energy inputs per 1 ha of crops, but the lowest energy consumption per ton of silage obtained.

The aim of this study was to analyse the competition position of Polish breeding companies on winter rye market compare to foreign companies in years 2009-2013. It was found that in the analyzed period market position of Polish rye breeding companies in Poland is still dominant. Nevertheless, the market share of foreign companies is getting high. Noteworthy is mainly company KWS Lochow Polska Sp. z o. o., which manifests itself, inter alia, the amount of registered varieties and participation in the seed multiplication, especially hybrid rye.
