A partial botanical survey of a gamepreserve
Published July 31, 2012
27-30

Hungary is internationally well known for its high level game management. An important part of game management is indoor game keeping. In Hungary more and more game preserves were founded all over the country. The role of these game preserves to retain forest stands outside of the closed area. According to the law, in the game-preserves the gam...e bearing capacity is not the most important parameter, because in these areas the feeding is continuous. In practice it means that in game-preserves we find a much higher density of games than in nature. This causes a relative big loading of the area (of the herbaceous and arboreal), where the game-preserves are located. Our aim is to study the ecological and management issues of forest- and game resources. The scene of these work is a game-preserve related to the Nyírerdő Corporation (Nyíregyháza).
We have done a botanical survey (plant coverage, life-form spectrum) in the three previous units and in the control area (outside of the game-preserve) as well. Our results show the difference in case of the state of herbaceous plants between areas with higher and lower game density.

Element Content of Herbaceous Plants in the Floodplain Meadows
Published May 4, 2004
55-58

Animals require well-balanced nutrition. The elemental content of the vegetation of meadows is influenced by as many factors such as heat, rainfall, irrigation, soil type and nutrients, meadow types, species, aspects of the vegetation period and cultivation.
Natural meadows used extensively are common sights on river floodplains. Since chemi...cals are banned and the species number is high, measuring the elemental composition of plants on these meadows is beneficial. Cenological survey and element content measurements were held on the rich flora of four natural meadows in the year 2001.
Weeds, in a wider sense, are plants not directly involved in growing, although their nutritional values make them important costituents of feed. Meadows are enriched by their relatively high microelement content.
On the sampling sites, the ratio deviated from the ideal 2/3 parts monocotyledon and 1/3 part dicotyledon, but this did not mean a Mn deficiency as it would have been assumed.

Analysis of Economic Efficiency of Energy Wood Plantations
Published September 2, 2009
53-60

After the EU-accession we should have a definite idea about what kind of production structure and land use should Hungary obtain to meet the conditions undertaken in the different governmental decisions. In the course of Hungarian land use, significant changes have taken place in the last eighty years. Further changes are influenced by the fact... that according to various decisions, legislative provisions and ideas in a short time the energy orchards’ domiciliation could start in large. For this, financial support can be required from EU-sources. As for the woody energy plants, subsidies can be required for the domiciliation and as for herbaceous plants grants can be required for growing. As far as the latter is concerned, the subsidy will be around 26-27 thousand Ft/hectares according to the plans. However, the cultivation method does not have to be changed to
switch from plow-land to energy plants. The question is if the produced commodity will be received by power plants and if it ensures appropriate income for the farmer. In my research I wanted to find from the given woody energy plants which are those that are the most profitable.

Investigation of the effects of biggame-preserves on forests with different species composition
Published December 16, 2012
21-24

Hungary is well known for its high level game management. In order to develop a concentrated and more profitable gamemanagement new game preserves were established in the last few years. According to the law, in the game-preserves the game bearing capacity is not the most important parameter, because in these areas the feeding is continuous. In... practice it means that in gamepreserves we find a much higher density of games than in nature. This causes a relative big loading of the area (of the herbaceous and arboreal), where the game-preserves are located.
Our aim is to study the ecological and management issues of forest- and game resources. The scene of these work is a gamepreserves related to the Nyírerdő Corporation (Nyíregyháza). We made forest structure survey to determine the main stand-forming tree species in the area of the game preserves as well as to estimate the number of the measuring points.

Caliometric characterisation of crop production byproducts
Published February 25, 2014
55-58

By the decreasing tendency of the fossil energy resources more emphasis put on the usage of renewable energy resources. The consideration of environmental protection and the efforts of the European Union make current the widespread usage of renewable energy within biomass energy. One of the determinative trends of biomass energy is the direct c...ombustion of biomass. Characteristically woody stocks are produced for this aim, but there is a considerable potential in several byproducts of growing herbaceous plants or of other processes.

In our study three byproducts of plant production have been investigated which appeared at the harvest. The Higher Heating Values of wheat, maize and sunflower byproducts have been determined by an IKA C2000 Basic adiabatic calorimeter. According to the statistical analysis of the measured data the HHV of the byproducts are different, and these values are in a negative correlation with the amount of ash in % (R2=0.873) appeared by the combustion.
