Impact of mole migration on soil factor indicators of extensive grassland
25-29Views:112We investigated the effects of mole walks in extensive grassland soil, focusing on changes in soil factor indicators, 3-3 times per year, in 2022-2023, in Karcag. Based on our results, we found that the drier year 2022 had verifiably higher carbon emission values, only on an annual average, than the wetter year 2023. We found no verifiable differences in soil temperature and soil moisture conditions. Based on our data, it can be concluded that the mammal of choice for the year 2023, the mole, does not have a significant impact on the carbon dioxide emissions of the grassland soil. Further studies in other habitat conditions are definitely warranted.

Effect of organic fertilisation on yield and soil factor values of extensive grassland
23-28Views:55The effect of different rates of organic fertilizer was investigated on a natural grassland with solonyec soil conditions at the Karcag Research Institute in the second year after application. Of the mature sheep manure treatments applied at 0-10-15-20 t/ha, the 20 t/ha dose was shown to result in higher dry matter yields. In addition, the 20 t/ha dose of organic manure was shown to stimulate soil life, as supported by measurements of carbon dioxide emissions, and to help better conserve soil moisture.

Benefits from pastures
129-137Views:73The value of a pasture is determined by natural factors as well by productional methods. In this study, natural factors, such as rainfall, temperature, altitude and soil composition, are examined - these also influence the floral composition of a pasture, which is, again, important regarding the value of a pasture. As regards productional methods, requirements of environment protection as well as professional management are emphasised on the basis of wide-scale experiments conducted in Hungary.

Analysing of yield and nutritional value of Zselic pastures and its evaluation by D-e-Meter system
33-38Views:55The future way of grassland management is greatly influenced by the new functions of the grasslands relative to the environment. This means that the role of raising nutrition will be expand by the role of keeping the natural resources. In the EU the price of the arable lands are controlled by the supply and demand, so the quality of the arable and the value of it come asunder. The market economy has to evaluate the arable reliable and accurate. In according to these sentences it is necessary to show the real value of soil quality, of arable in the register of estate. An important part of the sustainable developing is to find the adaptation to the local area and the nature. This aspect could be found in the multifunctional European Agricultural model and in the rural development too. Nowadays we use the way of the land evaluation known as the “aranykorona”, which is an obstacle to the way of the sustainability. The evaluation of grasslands in Hungary is not solved, the details we have are disused, so it is hard to plan the yields of the grasslands, we can estimate them a posteriori. In the D-e-Meter grassland module we start the evaluation with the DM yield of the characteristic grass. This starting point is modified with the factors proper to the area. The measured and the estimated DM yield were compared to each other at 3 grassland at Bőszénfa. To evolve an up-to-date evaluating system we analysed grasslands at the University of Kaposvár Deer Farm at Bőszénfa to find answers to the followings:
• Soil analysis of the humus, the N, P, K levels and the pH of the grasslands
• Describe the botanical composition by the Balázs-method
• The quality and the nutrition value of the grasslands
• Yearly yields of grasslands
• Analyzing of the results by the D-e-Meter system

The impact of production factors on the yield formation of grasses of various exploitation
13-18Views:138The lawn – following the forest – is the best manner of land use. 10.75 percent of Hungarian territory is grassland. 90-95 percent of the grass’s root system can be found in the upper 10 cm layer of the soil therefore and because of the large evaporating surface the grasses have a great water demand and weather sensitivity. Beside the nutritional ability and some extreme properties of soil (for ex. great salinity) there is an influence on formation of the grass-type and the yield. In our experiments the sites were utilised 2, 3 and 4 times yearly. At two sites for four years (2006-2009) and at one site for two years (2009-2010) the quantity and the distribution of the yield as well as other parameters were examined, which are not reported in this paper. This experiment is a part of a climate research project run at 27 sites in Austria. The laboratory analyses were carried out uniformly in the LFZ Raumberg- Gumpenstein Research Institute. The most important results of this study are the following: The productivity of the grass type formed on the Little Cumania lowland is very limited. In case of drought there was the highest yield decrease and at the same time in case of good precipitation there was the smallest increase of yield. The effect of grass utilization by late first cut at the poorestsoil site was very unfavourable. At the grass sites of better quality, the utilization manner of 3 or 4 growth, resulted in a better adaptation to the climatic extremities.

Global challenges and demands for grassland use
81-93Views:73The purpose of this review is to outline the status quo regarding multifunctional and social demands on grasslands. The products and services that grassland ecosystems can provide society are detailed. Existing agro-policies are reviewed as to how they reflect social demands on grasslands. A farm level analysis considers many factors that may influence the fulfilment of social demands. Conclusions are drawn on the future of grassland use under different socio-economic conditions. Traditional (meat, milk, fibre, medicinal plants, fuel, power) and non-traditional (branded products, biodiversity as gene pool, biomass for energy) products are identified. Services of grasslands are summarized at three different levels viz. globally (regulation of climate, air quality, water resources, soil health, carbon sequestration, maintaining biodiversity), regionally (aesthetic and landscape values) and locally (preservation of cultural heritage, maintenance of the significance of religion for pastoralism). Targeted policies are emerging that assist in sustaining healthy grassland ecosystems and fulfilling multifunctional demands at different social levels. In spite of these policies, the future of the world's grasslands seems to vary by country, according to the level of development. In poor countries, production from grassland will remain of vital importance (in some cases, with the threat of ecosystem degradation), whilst at the same time, ecological and amenity uses of grassland appear to be ignored. Trends in the function of grassland ecosystems in developed countries seem to be just the opposite. The importance of production is declining, while ecological and amenity functions receive increasing attention in response to multifunctional and social demands. Due to the national conditions the future of grassland use in Hungary will differ from these patterns. The production from grassland is going to be negligible. The ecological role (landscape, biodiversity) will remain very important. Remarkable increase is predicted in the amenity role of grasslands following the overall economic development in the country.
