Abstract The paper analyses the legal regulation of the cultivation of fast-growing trees on agricultural land in Slovakia and Czechia. The focus is on the differences in the legislation of the two countries, the application of the regulations of cultivation of fast-growing trees in practice, the level of protection of agricultural land, and the support system for the cultivation of fast-growing trees. Comparison of national legislation dealing with the issue of planting fast-growing trees, taking into consideration the protection of agricultural land and the legislation on granting the state support has also been investigated in the context of European legislation. The procedure before the start of planting, the permission conditions for planting of fast-growing trees, the conditions and the process of support provision have been studied. The result of the documents analysis is a comprehensive comparative overview of the above-mentioned areas of legislation on the cultivation of fast-growing trees in Slovakia and Czechia and the identification of differences, benefits and practical impacts on the cultivation of fast-growing trees.

Abstract The changes of selected chemical parameters were observed in Gleyic Fluvisols. The field experiment was established as a twofactor experiment with four energy crops (Arundo donax L., Miscanthus × giganteus, Elymus elongatus Gaertner, Sida hermafrodita) and two variants of fertilization (nitrogen fertilization in rate 60 kg ha-1, without nitrogen fertilization). Soil samples were taken from the depth of 0 to 0.3 m at the beginning of the experiment in the autumn 2012 and at the end of reference period in the autumn 2015. Land management conversion from market crops to perennial energy crops cultivation has influenced changes of selected soil chemical parameters. The contents of soil organic carbon were affected by cultivated energy crops differently. It was found out that Arundo increased the organic carbon content and Miscanthus, Elymus and Sida decreased its content. At the same time, the same impact of the crops on content of available phosphorus and potassium and soil reaction was found. It was recorded that each cultivated crop decreased the soil reaction and available phosphorus content and increased the content of available potassium.
摘要:观察了格列克氟维醇中部分化学参数的变化。田间试验采用四种能源作物(冬青、芒草、冬青、冬青)和两种不同施肥方式(施氮量为60 kg hm -1，不施氮)进行双因素试验。在2012年秋季试验开始和2015年秋季参考期结束时分别在0 ~ 0.3 m深度取土样。从市场作物到多年生能源作物的土地管理转变影响了土壤化学参数的变化。栽培能源作物对土壤有机碳含量的影响不同。结果表明，紫穗草提高了有机碳含量，芒草、百里草和西达草降低了有机碳含量。同时，发现作物对速效磷、速效钾含量及土壤反应有相同的影响。结果表明，各栽培作物均降低了土壤反应性和速效磷含量，提高了速效钾含量。

Abstract Agro-energy crop, Miscanthus × giganteus should be produced on marginal land in order to avoid land suitable for food production. Production of electricity in thermal power plants occupies large land areas by depositing tailings from surface mines, and depositing ash and slag. During the first year of Miscanthus × giganteus growing in containers, the concentration of heavy metals: As, Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn and Fe was monitored in underground and aboveground plant parts. The substrate was overburden from open pit coal mine RB Kolubara and ash from TPP Nikola Tesla B. Significant differences were found between the substrate and the investigated elements, but in all cases the accumulated heavy metals almost completely remained stable in underground organs of plant. It can be concluded that biomass of Miscanthus × giganteus could be used as energy source if it is grown on a soil moderately contaminated by heavy metals.
摘要为了避免适宜粮食生产的土地，应在边际土地上种植农用能源作物芒草。火电厂的发电需要通过堆存露天矿的尾矿和堆存灰渣来占用大量的土地。在芒草盆栽第一年，对其地下和地上部分重金属As、Cd、Co、Cr、Cu、Mn、Ni、Pb、Zn、Fe的浓度进行了监测。底物为露天煤矿RB Kolubara的覆盖层和TPP Nikola Tesla b的灰渣。底物与所研究元素之间存在显著差异，但在所有情况下，植物地下器官中累积的重金属几乎完全保持稳定。综上所述，在中度重金属污染的土壤中生长，芒草生物量可以作为能源利用。

Abstract The household income is one of the basic indicators of the human living standard in the countries or their regions. The indicator of income is very closely connected to the indicator of expenditures, which completes the view of the living standard of households. During the last two decades, there were some important events that have influenced the development of household incomes and expenditures in Slovakia, such as accession of the Slovak Republic into the EU, adoption of the common currency euro or economic crisis as well. In the last years, the net incomes as well as the net expenditures of the Slovak households have increased. According to the results, this trend will continue; however, the net expenditures will increase faster than the net incomes of households. Therefore, we can expect that the savings rate will decrease. On the other hand, the differences of net household income and expenditures among the regions of Slovakia were not eliminated. There is still a high difference of the net household income mainly between the Bratislava region and the Prešov region.

Abstract Importance of rural tourism as a specific form of tourism lies primarily in its potential to be a driving force for the development of rural municipalities and diversify their economic base. The aim of this paper is to verify this assumption, while analysing the relationship between the concentration of tourism activities and migration trends in rural municipalities in Slovakia. The results support the claim that tourism has significant positive effects manifested by a positive migration balance in municipalities where the tourism industry has a significant presence. The relationship between the level of net migration and rural tourism localisation index in rural areas is not entirely clear because of high diversity of rural municipalities. It is true that in the “catching-up” group of rural municipalities, where the previously negative trend of migration turned positive, localisation index of rural tourism reaches a peak, which may suggest that precisely this sector could be the driver of this positive development. On the other hand, there is a group of marginalized rural municipalities where the concentration of rural tourism industry measured by the index of localisation is also relatively high, but nevertheless, these municipalities suffer from a loss of population due to outmigration.

Abstract Climate change is a major current issue which affects natural, economic and social processes equally. Despite the widespread acclaim of the issue we still encounter economic and political solution models that are climate-sceptic and often contradict each other. As a result, national climate policies and social opinions constantly change in an active interaction with each other. Thus, this current study, based on the latest international literature, reviews and analyses the world economic tendencies, related social and political responses along which different official (national) standpoints are formed. Therefore, the interpretations of related scientific research results are often different, which can easily lead to unsuccessful problem solution.

Abstract In general, soil is perceived as an unreplaceable and unrenewable natural resource that allows plants, animals and man to live. It is significant in several ways out of which the most important is the production of food for population, the production of fodder for livestock and the production of raw materials for food and light industry. Due to these as well as the other reasons, land becomes the object of competition between different subjects which are trying to get it and use it. The aim of the paper is to map and to characterise the demand for agricultural land at the agricultural land market based on the certificates on fulfilment of the requirements on purchase of agricultural land. Based on the data collected throughout 31 months, it was proved that the demand for agricultural land is influenced by price, land quality, area, fragmentation of land ownership, distance of the offered plot from a county seat and localisation of a given land plot.

Abstract Algae represent a potential source of energy via anaerobic digestion. The aim of the study was to obtain the possible potential of green microalgae, which could replace the commonly used corn silage for the production of biogas in the future. The intensive construction of new biogas plants stations across Europe and the lack of arable land suitable for the cultivation of biomass for energy purposes are the fundamental reasons behind looking for the alternative raw materials for energy production as a substitute for commonly used input materials. When comparing green microalgae with conventional crops the high productivity potential (high oil content) as well as the possibility of their production during the whole year can be noticed. It is necessary to find the effective way to produce biomass from green microalgae, proper for energy conversion, while ensuring the economic and environmental aspects. The interim research results mentioned in this article indicate that microalgae present appropriate alternative material for the process of anaerobic digestion.

Abstract The paper deals with identification of drought in western Slovakia, which is based on soil-climatological data. For this purpose, three sites were chosen: Bratislava, Piešťany and Hurbanovo, situated on the Danubian Lowland. The Palmer Drought Severity Index (PDSI) was calculated on monthly basis for time series 1981–2010, 2021–2050 and 2071–2100. There were determined the driest periods by percentage of dry months for each site. The driest period in Bratislava and Hurbanovo was in the first evaluated time series. In Piešťany we can expect, that the second time series will be the driest. Linear trend of drying area will be revealed in period 2071–2100 for all three sites. The aim of the paper is to analyze and compare the occurrence of drought in temporal and spatial dimensions on the west part of Slovakia.

Abstract With the development of industry, agriculture, exploitation of natural sources and with boom of settlement density, the environment is being affected by potentially toxic elements; the phenomenon is consequently reflected on human health. Cadmium is a high risk element for the whole environment. The aim of this research was to analyse and evaluate sediments of selected water reservoirs during the ten-year period in order to determine the concentrations of selected, potentially toxic elements. For statistical processing, the correlation coefficient by the Spearman method and the analysis of the index were used. Sediments are reliable indicators of environmental pollution. The analyses of the sediment samples were carried out by the flow electrochemistry and the atomic absorption spectrometry methods. The total concentration of Cd in sediments was up to 22.60 mg kg−1 of dry matter. pH/KCl was marked in the range from 5.6 to 7.2. From statistical processing of sediments data by Spearman, we determined the dependencies between Cd and the following elements: As, Cu, Hg, Pb and Zn. The relations between Cd and the following elements: Pb, As and Cu were very highly positive.
