    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.

    The impact of converting overgrazed extensive grassland to mowing was investigated in Karcag between 2017 and 2020. At the beginning of the experiment, the plant composition of the overgrazed grassland community, which had been overgrazed for 3 years, showed a high and continuously increasing cover of unconditionally weeds avoided by sheep, which presented clearly higher quantitative indicators in terms of yield values. However, in the grassland communities that were converted to mowing, the cover of unconditioned weeds decreased steadily at the end of the experimental period and the cover value of grassland components valuable for animals increased, thus stopping degradation and recultivation by conversion was successful.

    1. A cserjés és kórós gyomok szárzúzás utáni sarjadékát, még elfásodás előtt, szelektív gyomirtó szerrel (MCPA + Dicamba 5 l/ha) kezelve teljes gyommentességet értünk el a kísérleti területen.
    2. A gyep termése az első évben a gyomirtás hatására csökkent, de ez pozitív hatás, mivel a füvek a gyomirtást követően nem szaporodtak még fel a területen.
    3. A csomós ebír és a magyar rozsnok felülvetése helyreállította a javított gyep vezérnövény- állományát.
    4. A tápanyag-ellátás javította a gyep hozamát, a 100 N kg/ha ammóniumnitrát hatóanyagú műtrágya-adag javasolható a gyakorlati felhasználásra.
    5. A nitrogén hatóanyag hasznosulását a területen hagyott növényi maradványok 10-20%-al csökkenthetik.
    6. A gyepalkotók faji összetételének javításával és a tápanyagellátás megfelelő szintű alkalmazásával helyreállítható és gazdaságossá tehető a terület állateltartó képessége.

    The coenological relevés were prepared in 2007 and 2008 on two pasture-lands in the Great Hungarian Plain. areas situated inside and near (0 to 50 meters far from) an animal husbandry farm belong to the first group. Coenological relevés gained from areas situated 50 to 150 meters far from intensively used areas belong to the second group. 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. Primarily, degradation of areas could be experienced. These negative processes are extremely heavy inside and near the animal husbandry farm.
