  We 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.

  The feasibility of first grazing of extensive sheep pastures was investigated by monitoring the height of grassland in the spring of 2022 and 2023 at the Karcag Research Institute, focusing on the effect of vintage in this manuscript. For 6 grassland plots with different parameters, potentially suitable for early spring sheep grazing, in a meadow on solonyec soil with no level of inputs due to environmental subsidies, we refined soil temperature, soil moisture and height of grassland vegetation at the same time of year. For both years, it was concluded that it is justified to start grazing sheep on the fallow grassland and the pasture forest.

  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.

  In the droughty spring of 2021, we investigated the rate of phytoproduction development in extensive grassland plots with solonyec soil conditions from the perspective of sheep grazing. During the empirical time interval of the start of potential sheep grazing, data were recorded on a total of 7 occasions at 6 different sites registered under one parcel number. Our results showed that the highest soil moisture values during the study period were measured in the fallow grassland, while the highest soil temperature values were measured in the grassland used as enclosed pasture. Plant height values were highest in the fallow grassland and in the grassland of the pasture forest. The lowest plant height was recorded in the enclosed pasture, although the highest nutrient availability was also measured here.

  Our studies were conducted at the Hungarian University of Agricultural and Life Sciences in Karcag, where in 2023, due to favourable precipitation and temperature conditions, we had the opportunity to study the phytomass yields of a massively reproducing annual Trifolium species in a saline soil condition. Yield measurements (green yield, hay yield, crude protein yield, dry matter yield) showed that in all cases higher yields were measured in the Trifolium angulatum-covered grassland than in the control grassland, and statistical analysis showed a close correlation in all cases. Through our studies, we aimed to provide new data on the specific floristic events in environmentally managed grassland in the Pannonian Basin from a farmer's perspective.

  The 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.
