A practical means of setting the scene for evaluating aggregated absorption risk in EU co-funded programmes related to project failure
63-66Views:191The main purpose of the mid-term evaluation of grant programmes is to assess relevance, progress, effectiveness and efficiency. There are several methodologies, tools and techniques applied in various evaluations to assess these programme aspects. An important area of the evaluation of both the financial progress and the effectiveness of the programme is to evaluate the risk of absorption which is indicated by various factors, inter alia risk of supported project failure. If a project fails in any EU co-funded programme in the stage of preparation or implementation, then the fund already committed to that particular project (assumed to have already been absorbed or “spent”) is to be reused again or is to face decommitment (funds have to be paid back to the EU). There are strict EU regulations governing the time scale of this re-use (n+2, n+3 rules), therefore it is of major importance to assess the risk severity (measured as the resultant of the volume of grant at risk and the chance of project failure) and build up an early warning mechanism which indicates if the risk reaches a critical level that requires immediate intervention.

Measuring projectmanagement efficiency by Data Envelopment Analysis
121-124Views:229I suppose that there is a relation between the success of EU-funded projects and the effectiveness of project management teams which implement them. To examine the accuracy of the assumption and the nature of the relationship I needed a measurement method that was suitable for measuring the effectiveness of project management teams implementing EU funded projects in a given construction. Since Data Envelopment Analysis (DEA) has already been used to measure the efficiency of decision making units in other areas, it seems suitable for measuring project management effectiveness and indirectly measuring project efficiency.

Relationships of the sport and the life quality in the University of Debrecen
87-96Views:232In the sport- life of the University of Debrecen there has been a demand formulated on the making of a comprehensive, long-term development plan, which obviously incorporates all
fields of sport. This document guides the way for people in the sport- life of the university how they could organise their activities connected with sport on a calculable, predictable level.
Necessarily, the preliminary collection of professional informations has been a basic requirement for the establishment of this document.
The program provides foreseeable instructions to the organisation of sport pursuits both for sport people in the university, and members of the sport spehere in a wider sense. It
offers a cohesive solution for all kinds of tasks defined with the sport life, and also gives a guidance for the various ways of realisations of these challenges. Thus it can answer such questions as for example how the university can conduce the initation of conditions for the healthy living through spare time sporting, how it can participate in the financing of contest sport with the contributing project of reinforcement training and how the university can support the sport life of handicapped people. The project also contributes to the cultivation of the sport traditions of the university by bankrolling not only the official university sport
life but also the leisure time sporting of the students.
On the basis of rethinking the situation of sport at the university with its future possibilities the program paraphrases the tasks of the university in the sport life, the long term aims of
university sport politics with its operative aims that should be performed and also the possible steps which lead to these purposes.
The target of the project is to turn the University of Debrcen in every field into a “Sporting University”. It means, that beyond the development of quality sport and outstanding contest sport a much wider range of university people should be included in sporting in order to utilize all the advantages of sport. With this the physical culture could become not only a substantial form of spending our free time, but with getting one of our natural everyday activities it can also become our lifestyle.
Sporting prominently contributes to both the university students’s and the whole society’s mental and physical wellfare, and it also helps to improve our helthstate on various fields of life:
with its special functions it is a means for establishing a healthy nation, for promoting common relationships, for nourishing the economic activity of people and also for strengthening the national values and one’s self-esteem through providing equal opportunities.
The prosperousity of contest sport at the university and the maintaining and protesing of its efficiency fortifies our selfregard, as it is able to hold appropriate sportsmen up as examples
to both present and future universtity students, and also offers exacting ways of entertainment. Besides all these the advataged purpose of the project is to find and delibaretaly include those
necessary mechanisms which are needed for the working of the sport market. -
Preface
5Views:122In the frame of a common “Hungarian-Ukrainian Intergovernmental S&T Cooperation Programme” which title is “Change of soils ecological characteristics of Ukraine and Hungary in the conditions of anthropogenic transformed ecosystems and optimization of biological processes of plants primary feeds elements mobilization” a Workshop was held in Debrecen. The member institutes of project participated with different presentation in this program.
The title of Workshop was: “Anthropogenic effect on the properties of Middle and Eastern European chernozem soils and on the sustainable agricultural production”.
The aim of the Workshop was to give relevant information about the present situation of the Middle and Eastern European Chernozem soils, especially emphasize the effect of different loading on the quality (properties) of chernozem soils. With the Workshop we would like to create a tradition for discussion about the anthropogenic effect on the soil properties and through it on the productivity of different soils. It was a forum for discussion of research results related to problems and possibilities for prevention of soil quality. With this possibility we would like to contribute to the sustainable agricultural production.
The papers were read for the publisher and we would like to show them in a separate supplement of Journal of Agricultural Sciences, Acta Agraria Debreceniensis as one of the results of the project.
The papers comply with the requirements of the scientific issue except those two which show the university and the department of the Ukrainian partner taking part in this project.
The participant Institutes of the project:
- Dnepropetrovsk National University, Faculty of Biology and Ecology;
- Kryvyi Rig Botanical Garden NAS of Ukraine, Plant Physiology & Soil Biology Department;
- Department of Agrochemistry and Soil Sciences of Centre for Agricultural and Applied Economics;
- Research Institute of Karcag, Centre for Agricultural and Applied Economics. The collaboration with Ukrainian partners was successful and we have confidence in the further cooperation in scientific research. -
Valuation of the National Agricultural Environmental Management Project’s Extensive Grassland Farming Target Project in Two Counties
20-25Views:141The National Agricultural Environmental Management Project’s (NAEMP) extensive grassland farming project is aimed at extensive cultivation on of nearly 1.1 million hectares of grassland, and at improving the state of grasslands with nature- and environment protecting methods. By using the 2002 data (the NAEMP’s first year’s data), I came to the following conclusions: Within the Extensive grassland farming project, a state subsidy was applied for on 8.94% of Hungary’s total grasslands. In Szabolcs-Szatmár-Bereg and Hajdú-Bihar counties, applied for state subsidies covered 12% of the grassland of the counties.10.45% of the projects arrived from the county of Szabolcs-Szatmár-Bereg, and 28.56% from the county of Hajdú-Bihar. In Szabolcs-Szatmár-Bereg, the support was 37.7% of the total subsidy, while in Hajdú-Bihar, it was 37.1%, unlike nationwide, which was 30.1%.The intensity of the applications is respectively 1.7 and 2.5 times more than the National (1.24) value.
In my view, in some fields, which are not between nature protected areas you’d better consider permitting intensive cultivation, simultaneously with grazing, with the observation of nature- and environmental regulations. -
Optimized balance between crop productivity, restoration and maintenance of vital soil functions and soil carbon sequestration and storage – the SmartSOIL (FP7) project
213-215Views:210Soils provide the most indispensable function of supporting the production of food and feed for a growing human population. At the same time they provide a range of regulating and supporting functions related to climate change and removal of greenhouse gases. The majority of the soil functions are closely linked to the flows and stocks of soil organic carbon (SOC); low levels of both flows and stocks may seriously interfere with several of the essential soil functions and thus affect the ecosystem services that soils deliver. Soil degradation is considered a serious problem in Europe and a large part of the degradation is caused by intensive cultivation practices in agriculture. The aim of the SmartSOIL project is to link the results of different scientific fields through a holistic and multidisciplinary approach and as a result develop a decision making tool contributing to sustainable development.

Today’s judgment of sub-statistical regions, the sources of development in the most disadvantaged areas, and the experiences of their utilization in the Sarkad area
105-110Views:139The system of our nation’s sub-statistical regions is before a change; its role in the Hungarian public administration has to be settled, which will be one of the most significant tasks of the forthcoming years. A prevalent question among the learned professionals is whether the sub-statistical regions will become local governments or they will keep their regulating and taskperforming functions? Public administration system of sub-statistical regions can be framed around three functions, which also determine the complements of the establishment: local government function, area development function, polity function. A strategic question is the equalization and development of the most disadvantaged. Here is where the LHH project, aiming at the development of the most disadvantaged sub-statistical regions, provides support. The main message of the program initiated by the government is “we will not abandon anyone”. In my article, the current state of the program in Sarkad’s sub-statistical region,
the area of my study, will be discussed. -
Estimating the amount and heating value of wood waste burned in households based on FICM HWP model output data
79-84Views:369A 2009 study published by the Regional Centre for Energy Policy Research (RCEPR) sparked significant debate within the Hungarian forestry and wood industry sectors. The study suggested a substantial shortfall in the balance of solid bioenergy biomass usage and sources, which it attributed to large-scale illegal logging. The Bio Screen CCE Project updated this analysis and quantified a 37.2 PJ (43%) deficit in the solid bioenergy biomass balance for 2019. This study investigates the extent to which household wood waste burning could account for this shortfall. Using the Forest Industry Carbon Model (FICM) HWP submodel, the authors estimate that over 1.2 million m³ of wood waste may be burned annually in households. The heating value of this burned wood waste for 2019 is estimated at 14 PJ, explaining 39% of the shortfall identified in the Bio Screen CCE Project’s 2021 report.

Effect of fish feeds with high vegetable oil and low fish oil content on the growth performance and innate immune system of common carp (preliminary results)
7-12Views:167Fish meal and fish oil are very important components of fish feeds used by aquaculture. They contain poly-unsaturated fatty acids, which are essential nutrients both for fish and human nutrition. However, sources of fish meal and fish oil are limited, there is a need for new feed components to supply the increasing fish production and the increasing demand for fish feed. The aim of AQUAMAX project, supported by the European Union is to replace the fish meal and fish oil with vegetable oils. As a participant of this project, group of immunology in Research
Institute for Fisheries, Aquaculture and Irrigation (HAKI) examined the effect of three different fish feeds on the growth performance, innate immune response and resistance against Aeromonas hydrophila infection of common carp in an in vivo experiment. Fish feed supplemented with Camelina oil, but still containing fish oil significantly increased growth performance of experimental fish and their resistance against the infection. Fish feed containing linseed oil only did not enhance the growth performance, and it had a negative effect on resistance against infection. Based on the experimental results it can be concluded that fish oil used in fish feeds cannot be replaced effectively with vegetable oils, but can be supplemented with them. -
Implementation alterantives of the CIVAQUA complex water management program in the Debrecen region
71-73Views:250Hungary is one of the countries in Europe which has the largest amount of water supply because of its geographical conditions. Water comes from the surrounding mountains makes this water supply even more bigger. This precious water base needs to be treated responsibly and the most efficient way. The Civaqua program is a project with the above-mentioned conditions, made by the Local Government of Debrecen and the Water Directory of Trans-Tiszanian Region. This project deals with the exploitation of the East-Main Chanel’s water for social welfare, agricultural and inverimental protection purposes in Debrecen and its agglomeration. The aim of this paper is to give an overall insight into the investment plans of Civaqua program and it is also examines its positive direct and indirect effects on the region.

Analysis of the Hungarian National Action Plan for Employment in the Framework of RuralJobs International Project
77-86Views:149Employment and creation of new jobs getting more and more attention both on national and on European level. The examination of this topic is especially important in rural areas of
Europe. There were several European and national researches dealing with this question, and there are new upcoming works which try to find solutions for citizents to decrease unemployment in rural areas. The RuralJobs, EU Framework 7. project presented in the paper is one of these researches. After a short introduction of RuralJobs and the task under workpackage two of the research, which analysis strategies, policies and programmes from the aspect of rural jobs, one of the documents reviewed under this task, the Hungarian National Action Plan for Employment is presented, in line with the most important stages of the EU’s
employment policy. -
Evaluation of supporting in Derecske-Létavétes micro-regional area
179-188Views:155The occasion that joining to the European Union general several new opportunities which are supporting development, changes and increasing disadvantages. We tried to capitalizing these resources less or major rate in national and international level too. These opportunities are projects, tenders whose longterm effects are measured difficulty, it is a hard task. In spite of this fact I feel it has got basement importance to determine project activity forming future developments and ways.
In my study I deal with Derecske-Létavértes Sub-region. My aims to survey economic background of this sub-region, seeking contexts between economical factors, influential agents and project activity or results. In a settlement level it is essential what kind of supporting forms are available for entrepreneurs, civil organization, economic development and local government, what are the founds could be realized their development plans. -
Marginalisation and Multifunctional Land Use in Hungary
50-61Views:161Our study prepared as a brief version of National Report in the frame of EUROLAN Programme. We deal with the interpretation of some definitions (marginalisation of land use, multifunctionality of land use, marginalisation of agriculture, multifunctionality of agriculture), with sorting and reviewing indicators of marginalisation and finally with the analysis of functions of land use. We suggested a dynamic and a static approach of marginalisation. We can explore the dynamic process by time series and the static (regional) one by cross-section analyses.
It is very hard to explain the perspective of the future of marginalisation of land and of agriculture in Hungary. The process of marginalisation seems faster in the agriculture in the coming years, but it depends on the utilisation of new possibilities given by the EU financial resources and by the Common Market. At this moment agriculture seems one of the big losers of the accession.
In the long term we should face considerable challenges in the land use. It is necessary to take into account that there is a supply market of foods and traditional fibre production world-wide. There are limited possibilities to produce and to market for example biodiesel (fuel), bioethanol, or maybe biogas. Thus the environment and landscape preservation becomes more and more real land use alternatives.
The environmental interpretation of the multifunctionality of land use: activities (functions) of environmental preservation and nature conservation in a certain area, which aim to preserve natural resources by the existing socio-economic conditions.
Preservation of rural landscapes is the task mainly for land-users, who can be commanded by legal means and can be encouraged by economic measures to carry out the above activity. In the recent past measures of „command and control” type regulation were predominant, however nowadays, especially in the developed countries, the role of economic incentives increases.
As a conclusion of our analysis we can state that as long as the main land-dependent activities (agriculture, forestry, housing, tourism, local mining) cease to be viable under an existing socio-economic structure, then it is hardly possible to sustain the rural landscape on an appropriate level by non-commodity products (such as environment preservation, cultural heritage, nature conservation, employment etc.).
1 The study was prepared in the frame of EUROLAN (EU-5 Framework Project), QLK5-CT-2002-02346, as a compiled version of the Hungarian National Report, The national project co-ordinator: Prof. Dr. Gabor Szabo.
A part of places with high ecological values coincides with the areas with unfavourable agricultural endowments and underdeveloped micro-regions. We think so that the marginalisation preserves the non-environmental-sound activities and hinders the development of multifunctional agriculture and this process can change only by joint utilisation of endogenous and exogenous resources and methods. Thus the successful programmes for agri-environmental protection and multifunctional land use can serve the moderation of negative effects of marginalisation or maybe the marginalisation process itself. -
Interpretation of rurality and the situation of land use in Hungary
79-85Views:385The summarizing data collection of our study has been carried out in the scope of the FP7-REGPOT-2010-1 ’UD_AGR_REPO’ project as a part of the cooperation with the University of Lincoln. The University of Lincoln is an important partner of the project, the knowledge transfer activities that have been carried jointly with them are multilateral. One of the most important cooperation areas is the analysis of rural areas, rurality itself, determination of breakout points, exploration of alternative income sources, diversification possibilities. Some part of the work of the University of Lincoln on the field of rural development is based on the assessment and documentation global similarities and differences of rural areas. Present study also contributes to that work, it has been prepared on the request of the University of Lincoln with the aim of providing insight into the special political and economic changes/processes that took place in Hungary, and through them into the structure and operation of the unique Hungarian rural areas.
The study first positions the definition of rurality and rural areas into context on the basis of official EU and Hungarian legal classification. Then it covers the important agricultural nature of Hungary, which significantly determines the possibilities and properties of Hungarian rural areas. The further description of rural areas is completed by some historical summary, the introduction of ownership changes, detailed description of employment and income conditions and finally by the listing of breakout points of rural areas as a conclusion.

The measurement of successfully completed projects funded by the European Union
9-12Views:210Projects funded by the European Union contribute significantly to the socio-economic development of Hungary, its increasing competitiveness, thereby the local people's general level of satisfaction, their ”happiness and prosperity”. Successful spending from the Union's funds, successful project implementation directly impacts all actors in the Hungarian economy and society. Therefore, to examine the factors that support or jeopardize the implementation of the projects is a priority at EU and national levels. My research and doctoral dissertation aims to develop a methodology to assess the management efficiency of projects supported by the European Union, implemented in Hungary taking into account all measurable factors (technical and special expertise) and the "suspected" factor (EU thinking learning).
I intend to draw up guidelines for future EU funded project management teams to realize projects successfully for the benefit of Hungary.

Preliminary Critical P-limit Values of 0.01 M CaCl2 Soil Test Procedure
18-21Views:216In the last decade, the 0.01 M CaCl2 extraction procedure was tested as a multi-nutrient extractant. In 1995-97, international joint research activities were carried out within the COPERNICUS project. Detailed calibration of conventional and the 0.01 M CaCl2 extraction procedures for pH, Mg and K were published.
The amount of phosphorus extracted using a 0.01 M CaCl2 solution is very low and reflects the intensity parameter of phosphorus bio-availability. As a readily desorbed P fraction of soils can reflect the soil P-supply and the CaCl2-P values are in close correlation with P-fertiliser rates and P balance. However, the effects of various soil characteristics on CaCl2-P values are different and their interpretation is difficult.
Relatively poor correlations were found between amounts of P extracted by conventional and CaCl2 soil test methods and, therefore, P limit values could not be calculated directly. To characterise the soil P supply at different sites, the CaCl2 desorbed P and the adsorbed P in a modified Baker Soil Test were also applied.
Soil test results of Hungarian long-term fertiliser experiments and recommended CaCl2-P limit values, calculated on yield effects and soil characteristics, are discussed. -
Examination of soil parameters based on the evaluation of the spectroradiometric reflectance characteristics of the topsoil
75-80Views:312In this article we are presenting the methodology applied to analyse and interpret the topsoil surface reflectance parameters of multiple samples collected in the Mugello valley area in northern Italy in October 2012. The main aim of the whole project was to discover geomorphological behaviour and situation of the area ino order to improve potential for correct dating of certain archaeological artefacts found in the nearby areas. One of the crucial problem researchers are facing in the area is the lack of understanding of the underlying geological and geomorphological processes that were describing and characterizing the area and that played important role not only in the current geography and landscape formation but also in the transportation of various sediments and artefacts. In this particular research the main aim is to examine the possibility of developing a quick way to assess low level properties of the soil using hand held spectrometer and rapid analysis of cross-section using in situ measurement techniques. In this work we collected over 2000 individual samples of topsoil surface reflectance properties that we organized into a spectral library. This library is then to be used to describe physical and chemical processes in the soil. To support the analysis results were compared to analysis results from different kind of assessments in the same area. Our results show a great potential of application of hand held imaging spectrometer in soil property analysis based on the top soil surface reflectance parameters.

Characterisation of a thermotolerant yeast, Kluyveromyces marxianus CBS712
7-13Views:319Fermentation at high temperature with application of thermotolerant microorganisms is a technological advantage in bioethanol production. Among the yeasts, K. marxianus has outstanding thermotolarance. The industrial application of the IMB3 strain occurs usually at 45C. The final aim of our project is the genetic modification of the K. marxianus CBS712 strain in order to achieve ethanol production at higher temperature than the currently applied. This requires the characterization of the CBS712 strain, with special attention to the determination of the temperature limit of its growth and the amount of the ethanol produced. The temperature limit of growth was 48C in YPD medium. Elevation of the temperature above 45C led to an exponential drop of the cell viability. Ethanol production was tested in shaking flasks, in MYFM medium, under oxigene limited conditions, applying variable concentrations of glucose (12–20%) and different temperatures (45–47 ºC). Preliminary results have revealed that the elevation of glucose concentration increased the amount of ethanol produced. The amount of ethanol (appr. 5%)+ produced at the highest glucose concentration was not different at the tested temperatures (45, 46 and 47 ºC). The observation indicates the potential in raising the thermotolerance of the strain.

Clay-pit systems fishfaunistic research in the Middle-Tisza
81-92Views:145After the regulation of the Tisza River the chance of successful fish propagation lessened. Natural spooning places in the river almost completely disappeared. The fish have to find an adequate place for their propagation in the flood plain. The period of spooning usually coincides with flooding of the river. At this time fish try to find the flooded shallow places for spooning. These parts mostly include the clay-pits beside dams, which were accidentally established during construction of the dams. At this place the fry can find the necessary food. After decreasing the flood the fingerlings and a part of the spooners are trapped inclay-pits as these latter ones are not connected with the river bed. The clay-pits usually desiccate during the summer. The trapped fish population is eaten by water birds or harvested by the local man population. This means a great loss for reproduction of some fishspecies.
Within the framework of the Regional Rehabilitation Program at Nagykörű, supported by the “WWF Hungary” and a “SAPARD project,” these clay-pits became connected with each other in a stretch of 5 km, and they were jointed to the Tisza by a collecting channel. The water level has been regulated by a flood gate so that the water enters the holes during the flood and is released later on in to the water bed.
Data on fish were collected from the Nagykörű Whole System, from the Anyita pond and some isolated wholes in Szandaszöllős in 2004 and 2005. First of all fish fry and fingerling were collected and the success of spooning at these places was examined. Fry was harvested by a 60 x 80 cm sized lifting net of 2x3 mm mesh size. In other cases nets used by anglers for catching prey fishes was also used. Data were also collected from local fishermen who participated in saving the fry and fishing of Anyita pond.
Of the several thousand caught fish specimens 28 species were identified, and among them 5 protected and 5 economically important species was found. Protected fishes were as follow: gudgeon (Gobio gobio), bitterling (Rhodeus sericeus amarus), weather fish (Misgurnus fossilis), spined loach (Cobitis elongatoides) and tubenosed goby (Proterorhinus marmoratus). Among economically important fishessamples of asp (Aspius aspius), carp (Cyprinus carpio), wels (Silurus glanis), pike (Esox lucius) and pikeperch (Sander lucioperca) were -
Effects of combined nutrient supply treatments on some physiological parameters of autumn wheat
241-251Views:264The Fleischmann Rudolf Research Institute in Kompolt is not only famous for plant breeding but the institute also surveys the effects of different nutrient supply methods since 1918. In 2017, we joined this research supported by EFOP 3.6.1 project. Our aim was to investigate photochemical processes – which is one of the most determinant in case of yield – of crops by in vivo field measurements. We measured the chlorophyll content of leaves using Minolta SPAD 502. We used miniPAM fluorometer to determine actual photochemical efficiency and non-photochemical quenching of PSII during natural light conditions and also to evaluate the pigment (chlorophylls and carotenoids) and water content of leaves we applied field spectrophotometer (ASD FieldSpecPro 3). We utilized these methods by various treatments (1. treatment with soil bacteria + head and base fertilizer; 2. treated by only head fertilizer; 3. treated by only base-fertilizer) in field experiment of autumn wheat (4.1–2.43–1.19 ha) in June, 2017. The difference between treatments was clearly detectable. In the case of the first treatment, physiological processes were more intense and the ripening occurred earlier. The obtained yield was the highest in the case of the area treated by soil bacterial. Based on the results, the first treatment can be recommended in practice.

Economic issues of crop based ethanol production for energetic uses
90-94Views:170The United States Congress passed the “Clean Air Act” in 1990, which targeted the creation and use of so-called “green fuel”. This Act came into full force on January 7, 1995. Its essence is that an oxygen rich component is added to fuel by which it burns more cleanly and harmful emissions of vehicles are reduced by 25%. This oxygen rich component is basically ethanol and its ether ETBE, made of domestically produced grains.
America’s traditional grain exporter status could be converted into a stabile income resource during production, many more valuable by-products – should this program succeed – are also produced, giving the opportunity for further utilisation either in the foods or form feeds industries, or as export products.
Ethanol or ETBE production is also important to replace fuel imports from any specific country, the additive which is necessary for producing the fuel is the imported product MTBE.
This programme therefore simultaneously assisted in environmental protection, agricultural and foreign trading issues as well as some market regulation issues. At the same time, based on grain production, it has an effect on the social strata by creating new jobs, especially in those areas which can be considered in recession due to the lack of any large-scale industrial cities.
In the future, the European Union should carry out this project and it will affect Hungary, as well. -
Integrated development strategy of the catchment area of the Tisza river
31-36Views:254The main challenge for mankind has always been to eliminate the borders of its living space, as well as to explore and discover its new faces. Contemporary literature strengthens this postulate. It is the preference of the experts of various fields in spatial analysis is to consider space to be repairable, changeable and organisable. In accordance with this axiom, the five affected countries in the catchment area of the Tisza river (Hungary, Romania, Ukraine, Slovakia and Serbia) worked out an integrated, mutual standpoint to support the problems of the catchment area and to exploit its opportunities with the aim to support transnational cooperation. They laid great emphasis on the existing resources which could become the driving force behind regional development directions. This study contains the summarised outcomes of the TICAD project (SEE/A 638/4.2./X) which was drawn up as a result of cooperation between renowned institutions of the five affected countries within the South East Europe Transnational Cooperation Programme (lead partner: VÁTI, Hungary).

The possibility of use of the 0,01 M CaCl2 and Baker- Amacher extractants for the determination of plantavailable potassium
7-15Views:160The Hungarian fertilizing recommendation systems use AL soil test for the evaluation of potassium supply. The 0.01 M CaCl2 is a definitely milder extractant, it extracts the easily soluble and exchangeable potassium amount. Its European introduction was already taken into consideration in 1994. The research project on this topic is started in several european countries, also in Hungary at the Department of Agricultural Chemisty of Agricultural University of Debrecen. Another advantage this multielement method is that the different element-ratios can also be calculated.
The Baker-Amacher extractant’s principle is that it contains a known amount of K, P, Mg in the CaCl2 solution. During the soil extraction adsorption and desorption process take place, so the adsorption or desorption can be calculated from the original and the final concentrations.
In this paper we introduce the results of comparing analysis of the samples (n=630) from Soil Information and Monitoring System. Our aim was to measure the use of new extractants beside conventional extractant (AL) for the evaluation of K-supply would be reasonable.
It can be stated that there is a medium close relationship (r=0.75) between AL-K and 0.01 M CaCl2-K. My calculations confirmed the results of former examinations, and proved that the two extractants don’t extract and change the same rate of K-fractions. We found that regression between 0.01 M CaCl2 and AL depend on texture classes, pH classes, amount of lime, and organic matter content of soils.
Comparing the relations between AL and Baker-Amacher we find relatively loose correlation (r=0.45). We stated that there are K-fixing soils among soils considered to be well supplied with potassium by AL. This might be caused by the high amount of mineral clay and the quality of mineral clay. We stated that the dK averages show that the Hungarian nutrient-supply categories characterize generally well K-supplement of soil.
It can be stated that it would be necessary to use new extractants to specify evaluation of plant available K. We found that the 0.01 M CaCl2 and Baker-Amacher extractants could complete usefully the AL procedure and could help effective potassium fertilization. -
The methodology of the Hooded Crow’s (Corvus cornix L.) colour ringing and the previous results
43-48Views:295The Hooded Crow (CorvuscornixL.) have moved in several Hungarian cities in the last few decades. It is breeding in Debrecen since 1959, and nowdays it’s presence can be detected at all points of the city, it is an permanent breeding species of the bird fauna. Our knowledge about the nature of urban races, including motion patterns, area fidelity is sufficiently incomplete. The aim of our research is to answer these questions by using our colour-ring program. In this study we present in details the methodology of Hooded Crow’s colour-ring program in urban area, and we also report our previous
achievements. -
Tourism and sustainability in Hungary
135-143Views:171Sustainable development is a very popular conception since many years. In practice there could be many difficulties.
Economic, social and ecological systems are too complex to see all the consequences clearly. After all, sustainable criteria are indispensable for responsible planning.
Tourism is one of the world’s dynamically developing economic sectors. But according to this development, we have to confront with a lot of negative effects, like air pollution, or mass. With globalization, the opportunities for tourism increase: thanks to modern transport, places which were too far to be accessible before are now able to be reached. But there are consequences to this expansion. Unfortunately, growth e.g. in air transport causes considerable environmental damage.
In today’s fast-paced world, the sanctity of nature, a soundproof environment, clean air and rural life have become increasingly important. With the growth of demand and tourism globalized, these values can damage or disappear in a short time. So, in tourism, it is vital to project development plans with sustainable principles.
Just as other countries, in Hungary, the development of sustainable tourism is slowly becoming a priority. Fortunately, in plans for the next few years, there appear more concrete ideas on ways to make sustainable tourism grow.
In my study, I assess Hungary’s position in sustainable tourism, examining how sustainable tourism indicators fit in sustainable development indicators and how can we measure aims of sustainable tourism.
