    We carried out our surveys on grasslands near Parádóhuta. The sample area was a mountain grassland (Festucetum rubrae-Cynosuretum Tx. 1940, Soó 1957), which was mowed until 2013, then foraged with borzderes and racka cattle within the framework of nature conservation management for two years, and after that it became mowed again. We analysed the effects of foraging and mowing between 2013 and 2019.

    Our goals were the following: to disclose the vegetation of the sample areas (i), surveying the natural regeneration of the grassland and analysing, valuing the effect of mowing and foraging on grasslands (ii); analysing the vegetation in terms of nature conservation and valuing its life form spectrum (iii).

    The analysed grassland was very diverse in 2013, we noticed well differentiated Nardus stricta patches. In 2015 the vegetation became more mosaic-like because of heavy pasturing: animals have grazed arboreals and Nardus in lesser amount, but species diversity declined and coverage of shrub remained the same. In the last years of the survey foraging stopped, and mowing began, which increased the coverage of herbaceous plants, which approximated the values of the first years. According to our results, on these habitats systematic mowing has a much more positive effect on biodiversity and coverage of species marking naturalness.

    From the point of view of the lawns' current existence, use and their existence for the future, but the tasks, goals and challenges of grassland management have changed, and in line with this, we have carried out surveys and developed and modified a method for fast and efficient application.

    In practice, it is very important to know the quantitative and qualitative characteristics of the forage found in the pasture, as well as the exact economic value of the pasture. The purpose of this study is to present a cheap, fast, reliable and easy-to-apply estimation method.

    We took the previous methods into account and corrected and further developed them with the help of recent lawn management research results. Based on our tests, the corrected Balázs method can be used well to estimate the yield of grasslands and to determine the fodder value of the grassland. This method is cheap and requires no technical background. It also has the advantage, based on experience, that it takes into account the preference of species by animals.

    The data from the cenological survey and the height measurement of the plant stock can be used to estimate the yield, fodder value and economic value. Being a non-destructive method involving minimal trampling, it is also particularly suitable for monitoring the grassland habitat of protected plants and animals. The method is also presented on a sample example, which proves its applicability.

    There is a very old practice of grazing livestock in Hungary. Plants of the pastures are the most valuable feed for grazing animals. Supplementation of feed rations with fibre improves the saturation of the digestive tract, resulting in calmer animals and improved animal welfare. Grasses of pastures can be a useful supplement as they contain a lot of digestible fibre. Our purpose was to find out the grassland management values of sandy grasslands dominated by Festuca species along the Danube. We carried out cutting samples along the Danube, from the north-western part of the Little Hungarian Plain, through the sandy plains of the Carpathian Basin, Serbia, Romanian Plain to Bulgaria. The cut samples were analysed in the laboratory of MATE based on Weende analysis. The original dry matter, crude protein, crude fat and crude fibre content, as well as the measurement of fibre fractions (NDF, ADF, ADL) were analysed. The results showed that absolute dry matter, crude fibre and NDF contents were high in all samples. The five samples of Festuca species analysed showed significant differences in dry matter and crude fibre. Festuca wagneri had the highest dry matter content. The highest crude protein content was found in samples of Festuca vaginata, Festuca wagnerii and Festuca rupicola, but the highest crude fibre content was found in samples of Festuca tomanii.

    Sample grassland sites were investigated in Kővágóőrs (Káli Basin, Balaton Upland National Park, Hungary). The sample quadrates were designated in the following places: close to (0-100 metres) and away (250-500 metres) from the stable. Comparative coenological studies, forage values were investigated. Changes of species composition and ground cover, measure of possible regeneration or degradation were evaluated. It was examined how important grasses and pulses appeared or disappeared, how did the number of over-grazing tolerant species changed and how did the species composition influenced the nutritive value of the grassland. Results proved that among the plants there are either weeds poisonous and/or protected species, as well. Based on the results the characteristics of the examined grassland show the effects of grazing. According to results, observed grasslands have unfavourable species composition due to improper management practices and insufficient technological conditions.

    Due to changing land use, traditionally managed grasslands are rarely seen This is an unfortunate fact as regular mowing and foraging are the primary tools of maintaining these areas. These methods are of high importance in terms of nature conservation management, by affecting the successive processes. Natural disturbances are part of the ecological systems, and the majority of meadows and hayfields of high nature conservation value can only be preserved through management. By means of nature conservation treatments, the number of grasslands species can be increased and various accompanying species can be introduced.

    Climate change-induced extreme changes are making phytomass yields of extensive grasslands in continental areas increasingly dependent on the season. This situation is exacerbated, inter alia, by the decline in grazing livestock production due to a lack of quality labour, and thus by an increase in the proportion of unused or under-utilised grassland. In our experiments, we have refined the effects of a decade of zero, mulch, mowing and meadow utilisation on carbon emissions, soil moisture and soil temperature during two different types of years. We found that zero tillage with accumulated duff in the absence of utilization had the highest carbon dioxide emission values in different years, even at lower soil moisture values. Our results confirm the fact that fallow grasslands can be considered a source of risk due to their increased greenhouse gas emissions.

    The coenological quadrats were made in 1997, 2005, 2010 and 2021 in a sandy grassland which is used as cattle pasture. The quadrats can be sort in three groups. The first group of quadrats was made close to the cattle pen (Zone A: 0-50 m). The second group was made farther (Zone B: 50-150), where the grazing is not so intensive. The third group contains the quadrats which were made farther than 150m (Zone C). The animals use this area rarely, therefor this part of the pasture is undergrazed (Penksza et al., 2010a). The coenological survey was carried out with 2×2 meter squares, recording the cover value. The species names follow the nomenclature of Király (2009) and Engloner et al. (2001).

     

    The rate of species which indicate degradation is the highest near to the cattle pen (0-50m). But farther than 50m the rate of species which indicates naturalness is higher. Lower  nature conservation value can be observed near to the cattle pen. In this area weeds and degradation tolerant species can be found in the highest amount. Their ratio grew in the second zone (50-150m) too in the past few years, but the species which compose the natural vegetation also survived, so the species composition is able for regeneration. With the decreasing of grazing intensity the sample area could meet the requirements of nature conservation.

    Data evaluation was made with considering naturalness state in case of habitats; and on the other hand, according to relative ecological factors of occurring species. A significant change in species composition could be detected. Particularly, deterioration of areas could be experienced. These negative processes are extremely heavy inside and near the animal husbandry farm. Even aggressive, invasive plant species occurred. Among dominant grass species, dominance relations and covering rate of disturbance tolerant Cynodon dactylon and Lolium perenne species have increased, caused partly by overgrazing and trampling as well. A new species, Poa humilis, appeared in the zone “A” in 2020, which is a degradation indicator species and tolerates overgrazing and trampling (Penksza and Böcker, 1999/200; Penksza, 2009). Farther from the farm, rate of degradation showed by vegetation has decreased compared to the areas closer to the farm, however, it has increased even on the farther area between the two time periods. During the preparation of management plans for the grasslands, these data should be considered at a higher rate in favor of preserving natural values,

    There have been some important changes in the land use and land possession during the last two decades. Land possession and land use were separated. Farmers typically work on rented lands all around Hungary and in the Great Plain too. The land market got frozen. During our survey we were looking for answers on the effect of transition caused to sheep branch and on the perspective the sheep farmers would have in the future. We found that the rate of rented lands was higher than the national average and the rate of rented grasslands was even more higher (75%) in the period 2003-2006. Farmers working on small lands and having low profitability (like sheep farmers) will have the worse chance to buy land after 2011, when the land market will be opened for foreigners. The land possession and the land use will be more separated for sheep farmers that reduces the viability of sheep farms. Due to the low profitability and the higher rental costs the native sheep population will decrease further. The sheep branch need a subsidy which is based on the breeding level and the bred utilization and also the SAPS or the SPS subsidy should be based on the livestock populations in case of grassland subsidy.

  • Different agrotechnical mesures on the ecology and conservation in a wet meadow

    In grassland management systems, the various agrotechnical elements have to be used in many cases on "primitive grasslands", where the coordination of agricultural and nature conservation tasks is necessary. Here, animal husbandry is the main aspect, which includes the long-term preservation of the quality of the pasture, as well as the most economical use of the pasture and keeping the animals as cheap as possible. The tests were carried out on a grassy area on the border of the settlement of Aba. We examined the vegetation of 8 plots of the same size in the area and the quantitative and qualitative composition of the biomass produced there. In this thesis, we provide data on the vegetation composition and evaluation of the following treatments. The plots and treatments were as follows: I. plot-ventilated; II. parcel-relaxed; III. plot loosened and ventilated; ARC. parcel control; V. plot-ventilated and 15 t/ha manure; VI. plot loosened and 15 t/ha manure; VII. plot loosened, ventilated and 15 t/ha manure; VIII. plot loosened, ventilated and 30 t/ha manure. In each plot, 5 ceenological recordings were made using 4 x 4 m quadrats. The estimated coverage of each species was given in %, taking into account the proportion of grasslands and other species. Among Borhidi's plant ecological indicators, the species were evaluated based on the NB (relative values of nitrogen demand) and WB (relative soil water and soil moisture indicator numbers). The social behavior types (SZMT) were also defined based on Borhidi's work, and the nature conservation value categories (TVK) were defined according to Simon. The lifestyle analysis was performed based on Pignatti's lifestyle types.

    Based on the data, the composition of the vegetation of each plot changed significantly compared to the data of the control plot IV. A direct proportionality can be discovered between the increase in the cover value of the dominant lawn grasses, primarily Festuca arundinacea, Dactylis glomerata, Alopecurus pratensis, and Fabaeceae species (e.g. Lathyrus tuberosus, Lotus corniculatus) and the amount of applied nutrients. Based on the coenological survey of the eight examined areas, the control area (IV.) showed the most natural state, which was confirmed by the species composition and number of species. The IV. plots are close to I., II. and III. for plot recordings, which proves that aeration and loosening do not worsen the condition of the lawn, but rather promote the preservation of its natural state. The VII-VIII. plots have the smallest number of species, but based on the life form spectrum, naturalness indicators, nature conservation value categories and social behavior types, they are not very disturbed habitats.

    No significant difference can be detected between the effect of lawn loosening and lawn aeration, but III. plot, where both treatments were carried out, was closer to the control area. Regarding the effect of the lawn management methods, it was possible to produce a starting data set in the long term (with the same environmental conditions). Overall, the study gave valuable results regarding the age of change occurring during the application of different lawn management methods, and was also effective from an economic point of view.

    This survey is connected to OTKA-125423, which examines the vegetation of sandy grasslands along the Danube. During this survey, two potentially horticulturally usable Festuca species was analysed: Festuca wagneri and Festca tomanii. The main questions were the following: are they usable in an urban environment? Do the to species differ significantly? Have they any morphotaxonomic feature which can by utilized in horticultural practice? Specimens of the two taxa, which were planted either into normal garden soil or into pots differed greatly. Specimens of F. tomani were usually larger and more uniform. Both taxa had the pot treatment well. Though the average lengths of leaves and inflorescence stems tended to be higher on the soil mixed with perlite, the coverage values were lower on it; thus adding expensive perlite to the soil might not be rewarding for the farmer. The two species differed from each other in several morphological parameters. The diversity of Festuca wagneri showed well in this survey, and this taxons parameters would be also useful in horticultural practice.

    After the millennium the utilization of the Hungarian grasslands is particularly important. We considered the priorities of the Darányi Ignácz Plan where the efficient utilization of the agricultural areas - including grasslands, pastures- by increasing the number of ruminants is the part of the rural strategy. The effective utilization of the by-product, the manure in croplands or pastures is particularly important, taking the increasing fertilizer prices within the continuously opening price scissor of the industrial-agricultural products into account. The patent of the Karcag Research Institute of CAAES RISF UD, the TERRASOL compost is a good alternative for farmers. We have already published the primary results of our grassland fertilization experiment, where we investigated the utilization of different compost doses and evaluated these from economic point of view. In this paper we examined the changes of the properties of the soil in the different treatments. We visualized our results by using GIS methods. We measured the moisture content, the penetration resistance and the CO2 emission of the soil of the four treatments. We determined that the 20 t/ha of compost dose is considered as sufficient to improve the investigated properties of the grassland soils under the droughty conditions of 2012.

    In accordance with general trends in agricultural and natureőconservation practice in Europe, grassland restoration and traditional grassland management has gained increased importance in Hungary. In grassland restoration using of low rates of seed (less than 30kg/ha) and hay cover is suggested. In the present paper the effect of hay cover combined with low rate of seed (25 kg/ha) is studied in early grassland recovery. We aimed at to answer the question whether or not the speed of grassland recovery can be increased with a combined use of seed sowing and hay cover. The establishment of Festuca species was favoured by hay cover combined whit seed sowing. The emergence of shortlived weeds was significantly lower on most of the fields treated with hay cover and seed sowing. The species richness and diversity of early weeds did not differ significantly in fields sown only and fields treated both with seed sowing and hay cover. Our results suggest that the combination of seed sowing and hay cover is successful in fields, where high rate of weed invasion is possible, thus intensive post-restoration management is necessary.

  • Comparative investigations of biomass composition in differently managed grasslands of the Balaton Uplands National Park, Hungary

    Phytosociological and biomass samples were collected in two territories of the Balaton Uplands National Park (Hungary) dominated by grassland habitats. Samples in the Tihany Peninsula had been taken in a pasture of Hungarian Grey Cattle. Studies were broadened to four areas of the Tapolcai Basin, Badacsonytördemic (undergrazed and overgrazed pastures, hayfield, control area). The areas were suitable for following up the changes of vegetation and production in every grazing season of a year. We evaluated the changes of species composition and ground cover, the measure of possible regeneration or degradation, and the changes of these factors from the viewpoint of feeding value. Covering rates of the grassland associations have doubled and species composition has improved in the Tihany Peninsula, however, forage value has not increased, due to the change in land use in favour of the natural area that is converting into grazing field. In case of the Taplocai Basin, low number of species (20 to 30) was detected in the undergrazed pasture and the control area. About one month per year grazing time in the undergrazed area was not enough to achieve a better state for species diversity, and the amount of forage remained high. The overgrazed pasture carries a low forage value and contains a high number of weed species, despite the spectacularly high total number of plant species (38 to 39), consequently, grazing pressure has to be decreased. Although the number of species is lower in the hayfield (26 to 28), species composition and ability for forage supply is much better, showing that the proper management of the area is taken here.

    In the present study, we aimed to investigate the coenology of the Kelemen-szék in the Kiskunság National Park. The coenological studies were carried out twice. We compared areas with different vegetation types. During these two surveys, we examined in total 90 quadrats of mixed grazed and fenced control areas.  Ones were grazed by Hungarian domestic buffalo and Hungarian grey cattle and others were no grazed. Based on these surveys, it is possible to conclude about spatial and temporal changes in vegetation as a result of livestock husbandry in the area. Due to the size and heterogeneity of the studied area, we intended to investigate small homogeneous areas and respective control areas. Coenological surveys were done on lower and higher lying pastures, saline soil areas and loess areas.

    In the study plots, grazing led to stability in the species composition of loess grassland and saline grassland, so that they also satisfy the requirements moof nature conservation. The dominant and character species of the associations, and the typical species of the genus Festuca have a significant cover value. The dense and tall Puccinellia swards require more attention, because they are more vulnerable against grazing. Grazing and extensive livestock husbandry, which can be applied in the future, is a suitable method for the management of lowland areas. In order to conserve the associations, preservation of grazing is necessary. To provide amount of biomass of areas, the grazing has a significant role. The conservation of native loess grasslands, even in the form of fragments, plays an outstanding function. Hence, based on the initial surveys, the combination of Hungarian grey cattle and water buffalo is beneficial in terms of nature conservation.

    Irrigating pastures is a viable option only in a few selected areas in Hungary, even though pasture is a water demanding culture. Species composition will be impacted by the climate change, reduced winter and spring precipitation and the increasing number of hot days as well as the rise in temperature. Coverage by dicots and C4 grasses will increase, resulting in a change in feed quality. Yield losses and deteriorating quality should be compensated by an adaptive agricultural technology. We examined the impacts of 3 utilization technologies and seasonal weather conditions on dry and mesic pastures in the years 2006-2010. Results indicated a significant difference in feed quality and factors determining nutrient content caused by water supply. On the dry pasture, humidity had a significant and substantial negative impact (highest significance, highest r-value) whereas the mesic pasture was essentially affected by precipitation. On the mesic pasture, high temperatures, strong radiation and high amounts of precipitation all had negative impacts on the digestibility and metabolisable energy content of grass. Crude protein contents showed strong correlation only with annual precipitation.

    In nature conservation, the aggressive expansion of invasive plant species and the preservation of valuable grasslands are a global problem. Based on this, the following question can be formulated: which animal species and breeds are suitable for habitat management? Is the water buffalo suitable for lawn care and to what extent? With the overview work, we review the results so far, highlighting domestic areas where we already have preliminary results and where previous data have already been produced. Based on this, the invasive Solidago was completely suppressed in the marshes of the Zámolyi basin, the pasture was completely transformed, and the dominant species became Sesleria uliginosa. Also in the area of the Zámolyi basin, there were significant floristic and physiognomic differences in the vegetation. You may find that buffalo grazing is a suitable habitat management method in both dry grassland and wet grassland. Therefore, in addition to being effective in the control of Solidago gigantea, grazing with buffaloes is successful both in terms of nature conservation and grassland vegetation from an economic point of view. The first stage of the long-term planned work is an overview of the work on the water buffalo. The research is supported by the creation of Innovation operational groups and the investment necessary for the implementation of the innovative project. call for tenders (VP3-16.1.1-4.1.5-4.2.1-4.2.2-8.1.1-8.2.1-8.3.1-8.5.1-8.5.2-8.6.1-17) and the Innovation and the New National Excellence Program of the Ministry of Technology code number ÚNKP-22-3-I-MATE/2 was supported by the grant funded by the National Research, Development and Innovation Fund and grant AKGF-119-1-202.

The areas were suitable for following up the changes of vegetation and production during the grazing season of the year. 5 replicates of 2×2 m phytosociological samples plots were examined on each grasslands according to the Braun- Blanquet method (1964) in April, May, June, August and September 2008. 118 Hungarian Grey Cattle were grazed on the pastures. 14 species were common in each saple areas, wich are dominant species of natural grassland associations (Agrostis stolonifera, Festuca arundinacea, Deschampsia aespitose) in the region. The overgrazed pasture had only low nutritive value and contained high number of weed species. About one month per year grazing time in the undergrazed area was not enough to achieve a better state of species diversity, although the forage production of the area remained high. The number of species and the 32 ha grassland was high (58) weeds was due to the high number of weeds, however the nutritive value of this grassland was poor. The species number of the hayfield was lower (31) than and grassland, however species composition was better and the nutritive was higher. It seemed that management was suitable and the hayfield.

    The invariably unfavorable agrarian environment can be neutralized only through a change paradigm change. This would mean the adoption of the practice of "wise use”, which implies the introduction of small game management supported with habitat management. Habitat management concerns 5-10% of the areas and predator management/control according to need result also in the increase of the target species; in this case, small game populations, by increasing the diversity of the habitat structure. The preservation of grasslands, their small game-friendly management, and the development and maintenance of a durable, undisturbed grassland structure primarily in the habitat margins play an essential role in this work.

    Loess vegetations of the Carpathian Basin have been ploughed for a thousand years. Therefore, in Hungary, it is also important to find out the composition of loess vegetation. Therefore, loess steppes of verges of the Transdanubia have nearly disappeared.
    The extent of the loess bedrock and its vegetation were significant in the Pannonian area, but nowadays (Zólyomi, 1936, 1958; Zólyomi et al., 1997), they have been left in only fragments, mainly because of intensive agricultural activities and expansion of agricultural areas (Rákóczi and Barczi, 2014; Barczi et al., 2004a, b; Penksza et al., 2011; Deák et al., 2016a; Valkó et al., 2018). Therefore, the patches are very important, extending mainly over the central plain of the Pannonian area, but also spreading up to the foothills (Bíró et al., 2018; Penksza et al., 1994, 1996). Thus, several researchers have investigated these remnant vegetation patches in the central Carpathian Basin, Szerényi and Kalapos (2000), Csontos and Tamás (2007), Csontos et al., (2022). However, most of the studies were made in the Great Hungarian Plain, where the role of the Cumanian mounds was also significant from among the remnants. These patches of loess remnants are considered as hot spots for vegetation (Deák et al., 2016b, 2022; Dembicz et al., 2018, 2020). In addition, verges alongsideagricultural areas and roads, where the vegetation has been reduced, are also very important as relics of the former vegetation (Csathó, 2008, 2011; Szentes et al., 2022; Bajor et al., 2016).
