    Opis:
    The present paper analyses the issues of asset supply in Hungarian agricultural enterprises. The results of empirical research carried out into specialized field crop farms have revealed a number of anomalies. By analyzing the indicators which describe asset supply, a substantial capacity surplus and capacity shortage existing paralelly was observed in Hungarian agriculture. Most small farms were seen to use their assets wastefully. If the costs related with machine use are modelled, a close negative correlation between farm size and machine use cost is observed. On the basis of cost structure examination and former conclusions, a clear affirmative answer can be given to the question in the title. Unfortunately, the present farming practice is that farms with capacity shortage procure the required resources in the form of renting services and not by way of other cooperation arrangement solutions.
    Celem badań była ocena problemów dotyczących dostaw produktów rolnych w węgierskich gospodarstwach rolnych. Wyniki badań przeprowadzonych na wyspecjalizowanych gospodarstwach rolnych wykazały wiele anomalii. Po analizie współczynników opisujących dostawy produktów rolnych stwierdzono znaczącą nadwyżkę wydajności, a także jej równoczesny niedobór w węgierskim rolnictwie. W większości małych gospodarstw rolnych odnotowano błędne podejście do zasobów, co skutkowało ich marnotrawstwem. Jeśli wzorować się na kosztach związanych z użytkowaniem maszyn, można zaobserwować negatywną korelację między rozmiarem gospodarstwa rolnego a kosztem użytkowania maszyn. Po zbadaniu struktury podstawowych kosztów można stwierdzić, że obecnie gospodarstwa rolne o niskiej wydajności zaopatrują się w konieczne zasoby za pośrednictwem usług płatniczych, a nie za pomocą innych rozwiązań zorganizowanej współpracy.

    Opis:
    An opencast mine may cause negative effects in many ways. Landscape scarrings of opencast mines are harmful in aesthetic respect, engines, machineries and periodic blastings may cause notable noise loading which are injurious even if these mines are situated far from the settlements because the noise from the mines may disturb animals living in the surrounds (Kerényi, 1995, 2003, Barótfi, 2000). Besides the listed impacts the dust accompanied to the opencast mining cause the most significant load to the environment of these mines. In this study, the extent of dust loading is examined in the case of a North-Hungarian perlite mine. Milling of the exploited perlite is carried out in the milling plant located within the area of the mine in Pálháza which cause additional dust loading. Settling dust loading was studied by 22 measurement stations within a distance of 3 kilometres from the mine, during the installation of which even cover of the study area was aimed. Gathering of the dust samples were carried out monthly from August 2004 to July 2006 thus we have a two-year database. During the laboratory tests, the amount of insoluble and soluble dust fractions, altogether making up the total amount of settled dust, was determined respectively. In addition to the meteorological parameters having the most influence on the spatial distribution of the settling dust (i.e. wind velocity, wind directions and the amount of precipitation, air temperature, humidity and irradia-tion) that is why an automatic meteorological station was installed in the proximity of the mine, i.e. within the study area. It gave us the necessary meteorolo-gical data during the examination. Knowing that the most significant dust loading derives from the opencast mine we can not forget that periodically during the agricultural seasons from the arable lands and during the heating seasons through the chimneys additional dust might get into the dust-traps. To determine the origin of the dust in each dust-trap the dust samples were analytical examined as well. By the chemical composition of the samples we could find out how big roles the pollution sources outside the opencast mine played and hereby we could detect how significant the dust loading originated from the perlite mine is in its environment.

    Opis:
    For the good established landscape planning landscape protection and landscape management actions have to take into consideration the actual conditions of the landscape elements. Earlier we dealt with the stability of the landscapes (Kerényi, Csorba, 1996), recently started to investigate the most important factors, which are endangers the proper functioning of the landscapes. Results are calculated for 229 microregions of the country, which are elements of the official landscape hierarchy of Hungary described in the Cadastral of Microregions of Hungary. The average size of the microregions are 100-500 km2. There are certain factors among which some have already elaborated, and others are being worked on yet. Degree of ecological fragmentation of the microregions by roads, railway lines and settlements was determined during the last year. In the case of large settlements the extent of inner parts, traffic intensities of the roads was taken into account, while in the case of railroads it was taken into consideration whether railway lines are single or double tracked. Results were purified using a weighting, where the location of the protected natural areas compared to the situation of the given settlement, roads or railroads was taken into consideration. In the calculations it was taken into account as well that the agglomeration processes of the large settlements may restrict the ecological gates and corridors of the migration of plant and animal species. From the series of maps on natural threats on microregional level, the map of the hazards of drought is presented first. The map gives a definite answer to the question, in which microregions is profitable to establish irrigation systems; and how high is the uncertainty of the rate of their utilization. Global warming, however, may modulate the map resented here remarkably in the next decades. Microregions that have been classified into transition categories with moderate or medium level of drought hazard may fall into categories of serious hazard of drought in the future. A synthesizing map has been completed by summing the seven datasets of the indicator group of natural hazards and the weighting of the subsets. Landscape planning is strongly affected by tendencies of macro economy on the present land use structure. EU agricultural policies have just started to affect strongly on Hungarian land use structure, therefore attempts have been made in order to forecast their impacts. Present Hungarian land use structure has been compared to priorities of the EU. Prospective shifts in land use structure have been determined for the 35 regions of Hungary. According to the 8-10 factors mentioned above, we shall have a detailed database to evaluate the microregions of Hungary in order to characterize the most threatened landscapes, and the most dangerous impacts on the landscape functioning.
