Examination of compost maturity using reflectance
29-34Views:122Composting is one of the most popular recycling processes for organic waste. Composting plays an important role in waste and by-product management and is becoming increasingly important in both sustainable energy management and circular economy. Composting transforms organic matter to produce a safe and stable by-product (compost) that can be applied to arable land in a similar way to fertilizer. Physical, chemical and biological methods can be used to monitor the process and to determine the maturity of the compost, as spectrometric/spectroscopic methods play an important role in the analysis of different environmental samples.
Our aim was to (1) non-destructively detect the effects of different additive ratios on the spectral properties of the composting process and the spectral data of different compost mixtures, (2) to find the wavelength ranges of the reflectance curve (inflection points) sensitive to compost maturity, (3) to determine the correlation between the inflection points and the chemical and physical parameters measured in compost by conventional methods.
The mixture of broiler and hen manure and zeolite was composted 62 days in windrow composting. In the composting experiment, the moisture content and temperature (°C) were measured every three days and compost samples were taken and in 10% destillated aquaeous suspension were measured the pH and electrical conductivity (mS cm-1). Compost samples dried to mass stability were spectrally analyzed in the wavelength range 400–1000 nm with AvaSpec 2048 spectrometer.
Based on the results, the reflectance of mature compost were smaller in the last days of composting than the reflectance values of day 0 samples, thus compost maturity can be detected spectral in the VIS-NIR wavelength range. For the tested compost prisms, the reflectance of each sampling day shows a constant slope, with a significant overlap of the reflectance curves up to 400–700 nm wavelength range, and there was a breakpoint in the 700–750 nm wavelength range which was proved by binary encoding.

The Legal Rules Pertaining to Land Protection in Hungary
324-331Views:84Buildings in industry, mining, transportation and for personal and commercial activities cover increasingly more valuable agricultural land. The increase of sub-urbanization and vehicular traffic and the spread of malls and other kinds of investments are causing serious harm for not only to human society, but to a whole national economy as well.
The law on agricultural land (1994:LV) contains legal rules for the preservation, use and classification of agricultural land. These rules define the temporary or permanent use of land for agricultural and non-agricultural purposes; the scale of the land-protection fee and the rules of the process on cases in which land is used for non-agricultural purposes without the consent of the land registry. In the field of land classification, the law prescribes the regulations which are to be followed in order to define the net income of agricultural land in Golden Crowns.
Hungarian land protection rules are unique in the European Union, because only few member-states have similar laws to ours. Community law does not regulate the member states, except in the case of land classification, because this is the basis of the tax paid on the agricultural lands, but even here, there are differences among the states. -
Significance of PSI re-use
75-78Views:109The prime aim of this study is draw attention to the importance of the issue connection with PSI reuse, to give a survey of the attepts carried out so far, legal impoudments. With the help of this we are trying to systematize conceptual basic as well as to expand the fields researched. Regarding PSI reuse the 89/2003 Directives of EU serve far the prime factor, as well as the LXIII. act of 2012. Which is the adoptation of the directive in Hungary including its modfications.
In Hungary a new governmental strategy is being formed, which would make the widespread use of PSI possible. Doing so via their reuse it would contribute to establishing new products and services. By this means it would greathy support the improving competitivness of the Hungarian economy.

The role of Local wine administration bodies in creating social and cultural capital and in the preservation of local identity
181-191Views:71the target for the European Union to make Europe the most competitive and dynamic knowledge-based economy in the world. In this process, the education and training are of great importance for the member states. The restructuring of higher education, the modernization of the universities cannot be achieved without new financial resources. They should be ensured by increasing contribution of the private sector. However it is not enough to invest sufficient funds in the educational and training system, they must be expended efficiently. The free higher education itself does
not necessarily guarantee the equal access and maximal participation. The quality of higher education and equal opportunity can be improved, if the rising funds are expended on infrastructure development and creating an efficiently working student support system.
Quality, equal opportunity, efficiency – they are the most important views for the decision-makers in the higher education reform. In my paper, I would like to interpret definitions relating to higher education and in this way I attempt to evaluate the financing systems of the Hungarian higher education formed since the change of the regime, with special regards to the normative financial system combined with the payment of tuition fees. For classification, it is necessary to present the different basic financial models. Furthermore, on the basis of the above criteria, I try to make recommendations on how to improve the present financial model in order to achieve the Lisbon objectives.
The topic is important in our days, because tuition fees will be introduced in Hungary from 2008. The problem is very complex, although the analysts in most cases tend to approach the topic with prejudice, depending on their financial and political interests. My analysis may contribute to discernment in the tangle of the pros and cons. -
60th Anniversary of Hungarian Plant Protection Service
8-10Views:118The author briefly overview the history of the 60-year-old Hungarian Plant Protection Service, which has improved to a model by its ’golden age’ period with a well organized system and excellence of specialists on the chemistry period of Hungarian agriculture. The profound changes both in policy and economy resulted a serious structural changes which continue even nowadays. Meanwhile country borders have been opened than EU membership of Hungary have generated new challenges by appearance and spread of new pests.

The role of networks and clusters in rural development
57-62Views:56The development of rural areas is a key role for the European Union and its member states as well. The rural development primarily achieved through the development of agriculture, because the main beneficiaries of the grant are the farmers. Hungary today is close to 1 million units in agriculture, but only 10% are competitive. Agriculture as an industry according to its economic characteristics needs closely managed decentralization, where the autonomy of the units remain, but there is a central governing body, which constitutes a proffesional manager function. This is a superorganization, which stay above agricultural units, called cluster.

New wonder of an old hormone: Hungarian sour cherry varieties as natural melatonin sources
65-72Views:174Agriculture has always been an important role in economy, food supplies, sustainability of society During our experimental work an effective extraction procedure has been developed for melatonin. Further chromatography was developed the quantitative and qualitative determination of melatonin. A compound that was equal to the standard was purified from the extract by preparative HPLC technique and the structure of the purified sample was confirmed by MALDI-TOF-MS and NMR analysis. Based on our measurements, harvested in the state of biological maturity Hungarian sour cherry cultivars contain high levels of melatonin.
Our results show that "VN4" variety has extremely high melatonin content, 9.893 ug g-1 and suggest that "VN4" which were selected from the "Bosnyák" varieties is melatonin accumulating. The average value of the melatonin content of Hungarian sour cherry cultivars is 2.319 ug g-1.

Conceptions regarding sustainable agriculture – the national sustainable development strategy
42-51Views:73The task of the national sustainable development strategy is to provide a long term conception for the economy and society, so that this might function and develop in harmony with the environment. Creating the conditions for sustainable agricultural production requires the elaboration and implementation of long-term programs spanning generations. The objective is to find a compromise between the conceptions appearing in the long-term and the short-term programs.
In Hungary, several principles, conceptions and proposals have been suggested regarding sustainable agriculture. In the present study, I intend to systematize the above mentioned principles and conceptions, and compare them to the conceptions regarding agriculture in the national strategies of the EU member states. Furthermore, I examine to what extent the agricultural policy of the European Union supports the conceptions regarding agriculture in the strategies. This topic deserves special attention, as the Hungarian national sustainable development strategy is being prepared and is supposed to be finished by the end of 2005. -
Perspectives of air cargo activities in case of Debrecen International Airport
131-134Views:124The improvement of Debrecen International Airport has been taking place for more than a decade. The goal is to revitalise the domestic and international aviation of regional centres and connect the Debrecen centred economy zone with other industrial and commercial regions. Considering the market segments of the air cargo industry, and sizing up the requirements of the enterprises, we are seeking to answer for what possibilities an air cargo operation has, and scheduled cargo flights, what alternatives the location of a cargo base has. Getting to know the technical background of ground handling, communication, safety, and security, we can state that the airport is able to handle international cargo aircrafts as well. Regarding to the quantity of frights, we find that there is a possibility of two flights per week. There is minor need of handling dangerous or unique parcels. The surrounding area of working zone is an excellent territory for locating and building cargo facilities, and its technical background. In case of continuously increasing traffic it is suggestible to use the territory behind the apron as a first step of the development. As the activity extends the second step could be the improvement of the southern zone just beside the runway. This way primarily the
scheduled air cargo flights could appear, then as the traffic of commercial scheduled flights increases simultaneously could grow the amount of
small parcel transportation. -
Perspectives of the livestock sector in the Philippines: A review
175-188Views:2008The Philippine livestock industry is a vital component in the country's agricultural sector. It contributes around 18.23 percent of the gross output value in agriculture and provides livelihood to many people living in rural areas, signifying its importance with regard to the country’s economy. The constantly increasing demand for animal protein associated with the increase of the world’s population led to the intensification of livestock production, realized through the various initiatives implemented by the government, such as the import of high producing purebreds of various species. This strategy greatly influenced the country's animal genetic resource's diversity and increased food animals' population; however, it impacted the native breeds of food animals. Understanding the characteristics, performance and value of native and exotic breeds is essential to prioritize their livestock industry existence. Thus, this paper aims to characterize various native and exotic breeds of livestock in the Philippines and assess the current conservation of native animals.

Evaluation of supporting in Derecske-Létavétes micro-regional area
179-188Views:65The 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. -

The Presentation of Debrecen University’s Solar Energy Power Plant
259-263Views:73Energy plays an important role in everyday life and in the economy. The use of fossil energy sources greatly damages the environment. Besides this, the quantity of these energy sources is limited. Therefore, it is important to increase the share of renewable energy sources (solar, wind, water, biomass) in energy generation. Huge amounts of energy (1150-1300 kWh/m2) arrive at the earth from the sun, which utilized in passive and active ways. One of the active applications is photovoltaic current production, in the course of which electricity is produced directly with PV-Panels. This can be fed into the grid.

Innovation Potential and Regional Competitiveness studies in the Northern Great Plain region
223-228Views:981.5 million people live in the large region containing 3 counties, which makes it the second most populated region after Central Hungary. Its economy and land use are still defined by agriculture and it has been the least developed region in the country for a long time. In the country this region has the second lowest GDP per capita and employment rate. In contrast to the low values of the economic indicators the region has high potential for innovation. The University of Debrecen is located in the region having one of the widest range of education and intensive research and development is also a characteristic of the region.

Hungarian total foreign trade after the change of regime
145-154Views:73Hungary’s total foreign trade has changed a lot since the change of regime. Several factors played a role in this process. The collapse of COMECOM, set of the world economy, WTOagreement, Agreement of Accession and CEFTA-agreement and accession to the EU affected this situation. After the change of regime Hungary had to react rapidly to these new events: one of the most goals was to find new markets. Hungary’s total foreign trade balance is negative but this deficit has declined after EUaccession. The foreign trade in agriculture has realised positive balance for a long time. This balance is declining after 2004, in spite of that the agricultural export grows, but the import grows more dynamically.
Share of the Visegrad countries – join at the same time to the European Union as Hungary – from Hungarian agriculture exports gets higher, especially in the case of Poland.
Hungary’s trading partners of exports and imports are stabile and they come from old Member States. One hand is positive, but the other hand is not acceptable. It is important to get markets, because we strongly depend on Europe.
The situation of Hungary’s external trade is determined by the future of CAP and WTO Doha Round (reducing of agricultural customs, ceasing of export subvention system and etc.).
Hungary can keep in competition, if it extends its competitiveness, diminishes of costs, and improves of quality, logistic and marketing. -
The Role of Grasslands in the Diet of Geese
19-21Views:84A feeding trial was conducted with 4 weeks old growing geese. Feeding treatments were different proportion of chopped grass and grain pellets. Daily DM intake, weekly live weight gains and final live weight was measured. It is concluded that 25% of chopped grass in the diet has similar result as only grain pellet diet. This is good for the economy of goose production.

Comparison of Pálfai’s drought index and the Normalised Precipitation Index in the North Great Plain region
59-64Views:152Agriculture has always been an important role in economy, food supplies, sustainability of society and creation of job opportunities in Hungary. Our country has resource-related strength of agriculture, because we have more than 4.5 million ha for agricultural production. Agricultural production can be influenced by several factors, including climate, hydrology, soil conditions and antropogenic impacts. Climate determines the quality and quantity of the crop yields. The climate conditions in Hungary are variable and it shows spatial and temporal extremes. As a result of this, drought have become more frequent in our country (2003, 2007, 2009, 2012), which is reflected in the decline in yields as well. In the present study, Pálfai's Drought Index (PAI) and the Standardized Precipitation Index (SPI) were compared 2003–2012 in Debrecen. The temperature and precipitation data were calculated from data provided by a local meteorological station to work out PAI, while the SPI-3 index values were downloaded from the database of the European Drought Observatory. This allowed to drought assessment in a local and regional scale. Our study was supplemented with SPI-3, soil moisture anomalies, PAI and yields of wheat (Triticum aestivum L.) and maize (Zea mays L.) to evaluating the impact of drought on agriculture.

Effectivity indicators in the German agriculture from the 1990s till today
15-23Views:67Almost fifteen years have passed since the reunification of Germany. At the beginning of the 1990s, it was still unclear how the agricultural sector in the former East Germany would be able to survive, as it was still characterized by large scale farms, organized for a socialist economy. The course of this essay will look at how the agricultural productivity has changed the two different productivity systems in the western and eastern part of Germany.
Productivity can be defined as output produced per unit of input. If we define productivity indicator as output per one type of inputs then we get so-called partial productivity index, however, if we define productivity indicator as output produced per unit of more than one inputs we get multi-factor productivity.
In agriculture, the most often used partials productivity indexes are: labour, capital, land productivity and intermediate consumption productivity.
The analysis of total factor productivity requires the aggregation of all inputs by using input prices. -
Renewal of the city network in Szabolcs-Szatmár-Bereg country after the political restructuring
21-25Views:106After World War I., but especially from the second half of the 20th century the public policy development is determinative in urban development. The urban and the country planning appears under the auspices of the regional development policy between the world wars. After 1945 the primary goal in economic and development policy was the socialist industrialization, with a priority on cities. In this period the driving force in urban development primarily were the industrial installations. As a result, economic and social structure was transformed. It is a fact, that planned economy gave a huge impulse to city network, which determine the trend of cities up to this day. After the regime change, as an effect of escalation of regional differences and as a result of economic processes the urban development took new directions. The state intervention changed, and the principles of decentralization prevailed in resource allocation. The private and non-profit sector appears in urban development, the governments gain more important roles. These three sectors became the movers of local development. To recognize the main trends of urban development in Szabolcs-Szatmár-Bereg County, the local area development funds were examined in a special way in a given period. This study will show, the main tendencies of the consumption of decentralized regional development funds between 1996–2008, in the cities of Szabolcs-Szatmár-Bereg County. This study also gives an answer for which factors convert the renewal of city network of Szabolcs-Szatmár-Bereg County after the regime change.

Mitigation and adaptation measures in the hungarian rural development programme
245-250Views:60In the Hungarian Rural Development Programme (RDP) climate change adaptation is addressed through the measures in Axis 1, 2, 3 and 4. Under Axis 1 farmers can receive support for farm modernisation that will help them adapt to climate change. The processing industry will also be able to use the available resources for capital expenditure on buildings and new equipment. Axis 2 and especially the soil and water package within the agrienvironmental
measure aim to support production methods, which protect soil quality and will help adaptation to climate change. Measures of Axis 3, such as basic services for the economy and rural population, village renewal and development will provide local communities the opportunity to identify actions that can be undertaken to deal with the effects of climate change. On the other hand, the extension of forest resources contributes to climate change mitigation and enhances carbon sequestration. New methods have been elaborated to the sustainable regional water management, irrigation, water regulation, defence against internal water, and soil protection established. Water management contributes to the balance of water quantity on one side, but also to mitigating the climate change on the other. -
The economic potential of industrial parks in the Northern Great Plain Region
133-143Views:79The practice of the conception and park-like economic development (between market economy circumstances) seems to be novel in our country. The first industrial parks have been established decentralized, with a local initiation, with some determining foreign undertakings early in the 90 years. Since then the increase of the number of the parks is high also the areas which have weaker economic level. We have make attention (in
the development politics) to the industrial parks working in the most harmful micro-regions, where the capital task is to extension of the employment, and to involvement of the capital. In the Northern Great Plain Region there are 31 industrial park at the ends of 2007. There are developed infrastructure and service in the big part of the parks. The smaller part of the parks cannot live on its title of industrial park, because of regional position, and concerned their management troubles. But the extension and developing of the park’s economic is very important in the region. -
Decarbonisation and renewable energies in Hungary
89-93Views:118The decarbonisation of the power sector signifies reducing its carbon dependency. The aim of several programmes is making a conversion to a sustainable & low-carbon economy. Some of the targets by the EU are legally binding, thus appear in the national legislation and strategies. To meet the objective, we need to use renewable energy soures expansively.

What does precision crop production hold for the future of soil science and plant nutrition?
411-421Views:209The concept of precision agriculture is straightforward at the scientific level but even basic goals are blurred at the level of everyday practice in the Hungarian crop production despite the fact that several elements of the new technology have already been applied. The industrial and the service sectors offer many products and services to the farmers but crop producers do not get enough support to choose between different alternatives. Agricultural higher education must deliver this support directly to the farmers and via the released young graduates. The price of agricultural land must be higher if well-organized data underpin the production potential of the fields. Accumulated database is a form of capital. It must be owned by the farmers but in a data-driven economy its sharing will generate value for both farmers and the society as a whole.
We present a methodological approach in which simple models were applied to predict yield by using only those yield data which spatially coincide with the soil data and the remaining yield data and the models were used to test different sampling and interpolation approaches commonly applied in precision agriculture. Three strategies for composite sample collection and three interpolation methods were compared. Multiple regression models were developed to predict yields. R2 values were used to select among the applied methods.

Environmental Indicators – Agri-Environmental Indicators
248-255Views:66close relation. This means that policies related to the economy and the environment cannot be handled without each other. The United Nations Conference (Stockholm, 1972) was the first global conference to signal that environment concerns have increasingly become subject of mainstream socio-economic policies. The process started in the Seventies, laying emphasis on environment protection, plays an important role in the policy of international agencies. The use of environmental indicators is essential for monitoring the effects of environmental measures. The best way of evaluating sustainability if the results can be compared on a global level. International efforts are being made by the United Nations (UN), the Organisation for Economic Co-operation and Development (OECD), the Statistical Office of the European Commission (Eurostat) and other international agencies to develop a framework for environment statistics. This study deals with these frameworks, paying attention to agri-environment indicators. Hungary became a member of the UN in 1955, of the OECD in 1996, and will become a member of the European Union in 2004. The first summary in connection with environmental indicators of Hungary, taking the OECD Pressure – State – Response framework as a basis, was published in 1994. As a result, comparability of environmental indicators for Hungary with those used international are given.
