Possibility of testing italian ryegrass (Lolium multiflorum Lam.) with MALDI TOF-TOF MS
7-10Views:627Lolium multiflorum seeds were tested by MALDI TOF-TOF MS using 3 extraction solvents (NaCL neutral, NaCl acid, propanol). Our aim is to develop a method for grass seed testing. Among the 3 methods, only the propanol extraction agent was able to obtain a noise-free spectrum, revealing the m/z values of the reserve protein in the italian ryegrass seed.

Study of Trifolium angulatum phytomass in Karcag
31-36Views:562Our 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.

Impact of mole migration on soil factor indicators of extensive grassland
25-29Views:552We 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.

Arsenic accumulation in English Ryegrass (Lolium perenne)
67-68Views:336Arsenic contamination globally occurs in groundwater especially in deeper layers. Soil type, structure, water availability and land use both effect its concentration which varies between 10-170 µg/l. As more deep wells have been erected to access underground aquifers, arsenic accumulation became regular risk. Plants are in direct contact with groundwater therefore potential accumulators for heavy metals or metalloids. Through the food chain, both animals and humans are able to build up certain amount of metals and metal like salts. These elements accumulate in living tissues and may interrupt crucial physiological cycles (transcription, CO2-release). We focused on English ryegrass (Lolium perenne) because its known genome sequence and wide cultivar availability. This species is often used as optimal roughage for ruminants and horses. Also used as lab-plant because its fast germination rate.

Experiences with grassland aerator with blades in Karcag
3-6Views:535In 2023-24, we examined the effects of a lawn aerator with blades on plant structure, nitrogen, and total organic carbon content in a near-natural grass association in Karcag, characterized by saline soil. Following the aeration in October, by the following May, the nitrogen and total organic carbon content of the grass soil decreased. There was a decline in species diversity and the cover value of leguminous grass species. In contrast, the cover proportion of moderately oligotrophic, community-forming Festuca pseudovina increased. Additionally, the cover value of the dominant grass species, Alopecurus pratensis, also rose due to the two-time intervention with the blade roller. Summarizing our results, the application of lawn aeration in sensitive plant structures of near-natural grass associations is justified with great care.
