Determination of three small streams’ chemical water quality in Budapest
Published August 6, 2020
69-75

The location and development of cities has been influenced basically by various environmental factors. However, the relationship is bilateral, because not only the environment can affect the city, but the city can affect the environment in different ways, depending on recovery. This is especially true in the case of large cities such as Budapes...t where the different geological, geomorphological, hydrological, soil and bio-geographical conditions can be changed in very small areas, which implies that land use can be also modified as well. The aim of our study was to determine the chemical water quality of three small streams in Budapest which have same water flow and compare the field and the laboratory test results. Between many natural characteristics of these streams similarity is evident, however, several differences were found between the watersheds in terms of human land use. Statistical data analysis was performed as well, which was the aim to explore the relationship between the parameters. Overall, according to our study it can be concluded, the small streams have similar water chemical properties, but some parameters need special attention in the future, because the investigated small streams can be categorized into polluted and sometimes heavily polluted category.

The Importance of Urban Green Areas, the Examination of their Sustainability
Published August 21, 2020
29-33

A common characteristic of areas covered by plants is that they play a special role in shaping the environmental endowments of the settlement. The significance of green areas is further increased by urbanisation. We have conducted our research in the settlements of Homokhátság that includes the peculiarities and values of green areas and the ...prospective plant taxa that can be used with a view to sustainability.

Communication Strategy Use in English Conversational Discourse
Published August 6, 2020
61-67

The ultimate goal of language learners is to communicate efficiently and fluently in the given second language, which is hard work to reach. They are learning the language for long years, and it may happen that theoretically they are familiar with all the grammar intricacies, but practically they are not able to ask for even a glass of water in... real situations. The question is whether the use of communication strategies could help to cope with the difficulties by their direct teaching. A few years ago I conducted a research to find out what kind of interactive strategies the learners are using and to provide a full list of them. The publications at that time did not deal with strategies specifically in the teaching material. I used my own list. The latest books, however, put a stress on useful phrases. So the question is whether the fact that they draw attention to strategies in separate sections, will bring significant changes in the learners’  communication.

Examination of the heavy metal contant in urban soils in district XI. in Budapest
Published August 6, 2020
76-83

The soils contaminant content is influenced mostly in the cities by antrophogenic effects, such as building operations, vehicular traffic, inefficient saverage or drainage problems, when different materials add to the soil. These materials location and movements are changing continuously in soils. The pollution degree depends on the distance fr...om the surface, the composotion of the soil, the effect rate, the thickness of soil, the composition and proportion of soil-forming minerals. In our study the heavy metal contant in urban soils was examined in district XI. in Budapest, based on different chemical and mineralogical properties of soils.

The appearance of the conditions of sustainable development in the values of the population of Nagykörű: The results of a Qmethodology research
Published August 6, 2020
68-79

One of the aims of sustainable development is to keep the local communities, to ensure their local welfare, which is essential to eliminate or mitigate negative consequences. In our research, we looked for the answer, how the local population relate to sustainable development. What preferences do they have regarding the place of residence? Do t...hey see any inherent risks, threats? How long horizon they think and what problem solving techniques do they see? How do they think about sustainability issues? The responses were looking for with Q-methodology for which we have defined 46 claims in eight topics: local attachment; local cooperation; willingness to act; management; horizon; threats; solutions The Q methodology handles the respondents into factors, according to which claims they prefer more or less. The results are very well suited to understand the attitudes to the sustainability problems.

The Correlation between Nitrogen and Vitamin C Content of Celery in Sandy Soil
Published August 21, 2020
327-331

In our series of experiments celery test plants were used in lysimeter type pots. Plant growth, nutrient content and the relationships of them were observed. This publication shows the effects of different doses of nitrogen fertilizer (absolute control, basic +60/120/180 kg/ha N, and the base + 240 kg / ha N (calculated N from manure). The nitr...ogen content of the celery increased significantly depending on the N-doses; and a strong positive correlation (r = 0.815, p < 0.025 level) was detected in the tubers between N content and vitamin C. Our results establish that in our experimental setup on sandy soil, organic fertilization - enriching the colloid content and improving soil structure - proved to have the most beneficial effects.

NEW OPPORTUNITIES AND CHELLENGES FOR SUSTAINABLE LAND MANAGEMENT (SLM)
Published August 21, 2020
31-37

Special literature sources have been discussing the concept of sustainability and the feasibility options only for about three decades. Sustainable development has several definitions; it is defined both in narrow and wider sense. The definition of sustainability is regarded inevitable because the sustainability of agriculture can be interprete...d only within this fixed conceptual framework. Our study is primarily dealing with issues of sustainability in farming practices being peculiar to countries, regions of the European Union. In frames of current research, we are providing the analysis of the ability to produce value added within the agricultural sector, the intensity of farming, the non-renewable external input use, farm structure as well as the European-level relations being directed towards the preservation of land productivity.
