Settlement network, demographic circumstances, healthcare, social service and educations in Szabolcs-Szatmár-Bereg county
Published September 18, 2014

...5); font-variant-ligatures: normal; font-variant-caps: normal; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">Szabolcs-Szatmár-Bereg county shares its borders with three countries: Romania, Ukraine and Slovakia. The county is part of the North Great Plain Region, it is the third largest county of Hungary in terms of its population. The peripheric geographical location of the county gained importance by the EU accession, as the county represents a significant part of the eastern border of the EU.

Szabolcs-Szatmár-Bereg county is one of the counties of the Great Plain with significant population in the outlying areas, out of the six counties of the Great Plain the population of outlying areas is the lowest in the county, its ratio has been significantly reducing in the past decades. In the six counties in 1990 the population of the outlying areas represented 22.3% of the total population, whereas in Szabolcs-Szatmár-Bereg county the ratio was 13.6%. The ratio has dropped to 6.2% and 4.1% respectively.

The major aim of economic development is the improvement of the living conditions of the population, first and foremost by increasing family incomes. There are two main determining factors of family income level: employment ratio and the sectoral structure of employment.

Between 1992–2010 the number of employees in the financial sector decreased from 89 000 to 75 000, whereas the number of employees in the non-financial sector grew dynamically from 40 000 to 65 000. Structural change was significant. In the non-financial sector the proportion of the two main employment fields (education and healthcare) swapped. The number of employees in the education sector decreased from 16 000 to 14 000, while the number of employees in the health and social care sector grew from 11 000 to 22 000.

On the basis of statistics the number of kindergarten and primary school children reduced in the given period, while the number of secondary school aged children increased. In 1999 the number of secondary school children was 1/5th compared to the number of primary school children, whereas in 2010 their number almost reached 1/2. The student number in higher education doubled, which is a favorable phenomenon, though its structural changes raise some problems. The lack of technical trainings hinders exigent industrial development.

Since 1990 the education level of the population has significantly improved, the number and proportion of secondary school students and university graduates have risen much more dynamically than in other regions of the country. In the county the proportion of secondary school students increased 63% more than the national average, while in the case of university graduates the county passed the average national growth by more than 54%. Due to the effect of structural changes the proportion of university graduates in the corresponding age group improved, its backwardness compared to the national average has ameliorated from 34% to 29%, in the group of secondary school graduates the disadvantage has moderated from 26% to 21%. The computer and internet supply, as well as the number of teachers and students enrolled in secondary education institutions have developed dynamically in the county. Their growth has much excelled the national average.

Nutritive value of Timothy (Phleum pratense L.) during primary growth in 2005
Published December 21, 2009

In this paper we analysed the change of the chemical composition and nutritive value of Timothy observed during the spring of 2005. The nutritive value of Timothy was observed between the end of April and the beginning of June relating to the following parameters: crude protein, crude fibre, crude fat, ash, N-free extract, net-energy growth, ne...t-energy lactation, net-energy maintenance, Metabolizable Protein Energy dependent, Metabolizable Protein N-dependent. We also analysed whether a relationship between the environmental factors that affect the
growing period of grasses and the chemical composition can be detected or not. While testing for correlation, the number of days from 1st January, the amount of heat accumulation, solar radiation and rainfall were considered as independent coefficients.
For the estimation of weather conditions we calculated the climate index. The observed year can be described as a year with a rainfall above the average and abundant solar radiation. A correlation can be detected between the change of parameters of nutritive value and the quality of the current year. In 2005 the result of the analysis of nutritive value was showed a significance difference with respect to each chemical composition at the rate of P<0.001 depending on the time when the samples were taken.
According to the outlined data it can be stated that the change of the value of crude protein and ash show decreasing tendency agreeing the research literature. In parallel with the change of nutritive value, the amount of crude fibre and N-free extract increased. However, the value of Net-Energy maintenance showed an alteration only in the first half of the observed period. The same alteration tendency can be detected in the Net-Energy growth and the Net-Energy lactation.

Urgent agricultural issues of soil protection
Published June 30, 2018

The primary aim of this study is to draw attention to the importance of legal problems of soil protection. The basis for my study is the ombudsman’s 2016 principle of soil protection. This resolution summarizes the most pressing soil protection measures in 15 points that need to be taken as soon as possible to preserve soil resources. To narr...ow the wide range of topics, I will examine three points: (1) preservation of soil resources, (2) soil sealing, (3) brownfield instead of greenfield. Hungary is in a special position concerning this most ancient natural resource, as only 11% of all the land covered area of Earth consists of soil, the EU average is less than 30%, while in Hungary it is more than 60%. Despite the existing protective legal requirements, soil degradation is a constant issue. The persistence of population growth spells the need for more arable land, but as a result of the stressful impacts caused by people we are running out of useable topsoil.

Assessing both the short and long term process of land reclamation, it can be stated that more and more farmland becomes permanently and imperviously covered for other purposes each year, and as the arable land area decreases, the impervious surface area grows despite all respective decisions, regulations and prohibitions.

Stevia (Stevia rebaudiana B.) yield in the case of different production technologies
Published May 16, 2017

Stevia rebaudiana B. offers a natural alternative of sweetening, potential health promotion plant, and our country shows increased interest about cultivation in Hungary in addition to the neighboring European countries. The agricultural production system installation necessary
understanding of the needs of the plant, as well as exploring the... agronomic potential. Field experiments were conducted in 2015 with the aim to highlight some of the technological production parameters and correlations between them. We have reviewed the most important agronomic factors, the spacing (50×50 cm and 33×33 cm), ground covering (agro-cloth covered and uncovered/ control), their vegetative growth (first-,second-order branch), herb yield and quality in effect.
Based on empirical evidence, that the Hungarian climates also have the opportunity of 3 cuttings during a growing season, besides of early planting, optimal climatic conditions (in October didn’t reduce the daily minimum temperature below 0 °C, after cuttings the maximum interval values remain below 40 °C), and adequate water supply and crop protection facility. The 33×33 cm spacing evaporates more than 50×50 cm spacing, because of the dense population, the continuous canopy less able to breathe, so there are serious chances to the pathogen colonization.
Based on the results of our research to the wider 50×50 cm spacing favorable appreciate the stevia optimal progress in terms of qualitative and quantitative parameters of the yield. The stevia yields produced in the Northern Great Plains field cultivation can produce similar results as stevia crop yields in warmer climates, where the primary crops. Our research experience suggest that there is a viable domestic stevia cultivation, developing the necessary technology is still growing further investigation justifies.

Changes in toxic elements content of soil after sewage sludge treatment in energy willow plantation
Published May 16, 2012

The primary purpose of our experiment was the solution of municipal excess sludge treatment by a renewable energy resource used willow (Salix viminalis L.) plantation. Tests were carried out to state whether the applied sewage sludge has caused any accumulation of the toxic elements in the studied soil layers, and - based on the results –to whether the plantation is suitable for the treatment of municipal sewage sludge.
The excess sludge (sludge before dewatering) is beneficial for the willow, because it contains a 3–5% dry matter and therefore, a lot of water, too. This high water content ensures the high water amount needed for the intensive growth of the willow. On the other hand, the wastewater treatment plant can save the dewatering cost which corresponds to about 30% of the water treatment process costs. The amounts of the sprinkled sewage sludge were calculated on the basis of its total nitrogen content. Treatments were the followings: control, 170 N kg ha-1 year-1 and 250 N kg ha-1 year-1. The mean values of the toxic element concentrations in the sewage sludge did not cross the permitted limits of the land  accommodating.

The measured toxic element values of the soil were compared to the limits of the 50/2001. (IV.3.) Government Regulation.The  sprinkled sewage sludge on the bases of the total N content did not cause accumulation of heavy metals in the soil and the treated plants were also healthy without any signs of toxicity.
