Cím:UAV-based heterogeneity analysis of soil-plant-water system of small-plot experiment with different oat genotypes under Si and S foliar fertilization treatments / Erika Budayné Bódi, Erika Kutasy, József Csajbók, Solange Paola Acosta Santamaría, Tamás Magyar, Nikolett Szőllősi, Zsolt Zoltán Fehér, Péter Tamás Nagy, Attila Nagy, Tamás János
Dátum:2023
Megjegyzések:Five winter oat (Avena sativa L.) varieties were set in a small-plot field experiment to examine the abiotic stress considering silicone and sulphur foliar fertilization treatments under temperate and dry climatic conditions in Hungary. Numerous in situ and laboratory measurements were performed to describe the crop's condition at various phenological stages. Drones with multispectral, thermal and LiDAR payloads monitored the field both with high temporal and spatial resolution. A high level of GIS data assimilation was performed in order to handle the different spatial-related parameters in one interface. It is a multi-purpose experiment, and for all of them it is an important criterion whether the study was carried out in a truly homogeneous area. Practically, it means that we ignore the patterns of the crop or the soil. If this is not the case, the various parameters measured should be evaluated accordingly. Hence, our study's main goal here is to reveal the soil and crop heterogeneity level. For this, all the measured parameters are involved in the multi-parameter analysis by which the heterogeneity level of the site can be assessed. Practically, by this, we can answer the main question: is the field suitable to carry out analysis such as abiotic stress studies or yield prediction modelling on it or shall we handle certain parts differently? Based on the example of our experiment we design a workflow by which the heterogeneity level of a small-plot field can be assessed and provide a solution for how to handle it in order not to involve data which may mislead analysis.

Cím:Hydrological decision-making systems using high-resolution weather radar observations - a case study from Hungary / Zsolt Zoltán Fehér, Erika Budayné-Bódi, Attila Nagy, Tamás Magyar, Tamás János
Dátum:2023
Megjegyzések:According to past observations and long-term forecasts, the Carpathian Basin is distinguished by two precipitation trends. The frequency, length, and severity of periods of precipitation deficit and drought are increasing. Furthermore, as small-scale convective updrafts intensify, heavy thunderstorms become more intense. Both trends pose significant risks from an anthropogenic perspective. The former increases food insecurity due to intensifying droughts, which damages agricultural yields, while the latter mainly increases property damage via heavy hailstorms. The 2022 drought year demonstrated that effective use of available water is the foundation for sustainable growth, which may be supported by well-designed infrastructure investments and smart water management technologies. A rainfall radar system with a high spatial and temporal resolution that contributes to near real-time machine decision-making is one conceivable component of such a complex system. The Furuno WR-2100 precipitation radar, which was deployed on the outskirts of Debrecen in 2020 for benchmarking purposes, is the first component of such an intelligent decision-making system in Hungary. The radar's range comprises both urban and rural areas, allowing it to continually gather high-resolution test data for both urban hydrology and agricultural irrigation system developments.

Cím:Modeling of soil moisture and water fluxes in a maize field for the optimization of irrigation / Tamás Magyar, Zsolt Fehér, Erika Buday-Bódi, János Tamás, Attila Nagy
Dátum:2023
ISSN:0168-1699
Megjegyzések:Precision irrigation is becoming more and more important in agricultural crop production due to the limited water resources resulting from the negative effects of climate change. Modeling of irrigation can support decision makers in the maintenance of the quantitative and qualitative parameters of the cultivated crops, while improving the efficiency of water consumption. In the present paper, a 3D hydrodynamic model was created in the HYDRUS environment to support the modeling of the temporal changes and spatial variations in the water balance (WB) of a maize cultivated Hungarian study site, thereby providing inputs for irrigation scheduling and variable rate irrigation for stakeholders. Beside soil physical parameters, crop evapotranspiration (ETc) values were also considered as model inputs for the phenological crop development stages of the maize from the sowing to the harvesting. This period was between the 3rd of May and the 10th of September in 2020 and the 20th of May and 14th of September for the year 2021. The performance of the model for soil moisture conditions were validated by on-field soil moisture measurements. The overall performance (full vegetation period) of the model was good (r2 = 0.88 for 2020 and r2 = 0.91 for 2021), but slightly varied among different phenological stages. Based on the model, the water balance of the investigated area was determined without any irrigation, alongside the cumulative water fluxes (CWF) through the boundaries including the root water uptake (RWU) of the maize as well. The results revealed that the incoming precipitation was not sufficient to supplement the water content in the soil to the optimal soil moisture range, except when the precipitation level is high enough to balance it. It was concluded that the water balance was negative for the investigated time periods without any irrigation. The specific water deficit (WD) values were calculated considering the area of the study site, which is 1439 m3/ha for 2020 and 2068 m3/ha for 2021. From the obtained results, optimal irrigation schedules were presented to keep the soil moisture content in the optimal range (20.92-14.41 V/V%) in the modeled area for two different vegetation periods. It was found that due to the irrigation the crop water productivity (CWP) increased by 6% and 4% in 2020 and 2021. Overall, the model is able to cope with changing circumstances that could help to mitigate the negative effects of climate change with the reasonable use of limited water resources in the future.

Cím:Characterization of the biodegradation of synthetic and organic wastewater in an anaerobic tank reactor using microalgae / Tamás Magyar, Felipe Werle Vogel, Florence Tóth, Attila Nagy, János Tamás, Péter Tamás Nagy
Dátum:2021
ISSN:2062-0810 2063-4269
Megjegyzések:The anaerobic digestion is a well-known method in waste management of biodegradable wastes to transform waste to energy. Proper digestion requires optimal fermentation conditions to improve the quality and yield of biogas. The objective of this study was to characterize the biodegradation process of synthetic and organic wastewater. Microalgae (Chlorella vulgaris) were utilized as a bioindicator for anaerobic digestion and monitoring of the fermentation process. Besides bioindication, the viability of the microalgae and the chlorophyll concentration were also assessed in such fermentation processes, since microalgae can be a potential source for biofuel production and a plant nutrient. The biodegradation process was studied for a month in an anaerobic tank reactor. The fermentation processes and lengths of the fermentation stages were successfully monitored and separately identified based on the pH and gas development. Furthermore, the amount and dynamics of the biogas yield also revealed that the fermentation process was about 510 hours in both cases. In contrast, increased temperature in thermophilic range (45?C) accelerates the degradation processes and resulted in shorter hydrolysis (60 hours), acetogenesis (24 hours) and longer methanogenesis (81 hours) stages, where higher biogas yield was also achieved (59.3%). During the process, the concentration of nutrients showed logarithmical tendencies and COD showed power tendency in time. The extent and the direction of the changes were in correspondence with microalgae activity. In thermophilic circumstances, living microalgae biomass dropped significantly without recovery therefore such an environment is not a viable option for microalgae growth. Moreover, dead microalgae biomass seems to act as a substrate for fermentation slightly increasing the concentration of some nutrients in the wastewater.

Cím:Modeling of Soil Physical Properties in an Extreme Salt Impacted Grassland in Hungary / Tamás Magyar, Attila Nagy, Bernadett Gálya, János Tamás
Dátum:2019
Megjegyzések:Salinization is one of the most significant chemical soil degradation process globally, and also in Hungary. The high Na+ concentration represents a limiting factor considering the multifunctionality of soils and decreases the fertility and productivity in agricultural areas. In recent decades, the salinization process has been accelerated by the negative effects of climate change. The continuously increasing temperature tendency predicts higher water scarcity problems and results larger drought areas. Hungary is located in the middle of the Carpathian basin, this special geomorphological structure allows the rapid changing of wet and dry periods in microclimate, resulted salt leaching and accumulation even in a year. The described process is very different compared to the salinization of seaside areas, where the adverse impact of saltwater intrusion prevailed. Besides arable land, secondary salinization often can be found in grassland areas caused by the irrigation and the rising of saline groundwater level. The vertical salinization is a well-known research topic, although there is no available information about horizontal salinization. The soil samples generally are originated from boreholes, where the spatial extent of measured soil physical parameters possesses high uncertainty. The uncertainty of horizontal salinization modeling is also a limiting factor in accurate digital model in extreme salt impacted agricultural area. The investigated grassland is located in Ágota-puszta (part of Hortobágy National Park), which can be mainly characterized by saline habitats and animal husbandry. In this study, the evaluation method of horizontal salinization is presented based on high-density point cloud 3D LiDAR technology, allowing the detection more effectively. Run-off and saline accumulation processes were examined in order to determine the optimal water balance. The developed model contributes the better understanding of horizontal salinization, resulting higher accuracy in horizontal modeling.

Cím:Management of alternative water resources for variable rate irrigation - a Hungarian case study / Attila Nagy, Zsolt Zoltán Fehér, Andrea Szabó, Erika Buday-Bódi, Tamás Magyar, János Tamás
Dátum:2023
Megjegyzések:Most of the climate scenarios predict increased water scarcity in arid areas, such as Hungary. However, the irrigated area in Hungary covers 2% of agricultural land, mostly with outdated irrigation technology. The aim of the research was to develop the basis of a variable rate irrigation for water-saving precision sprinkler irrigation system on an arable area (85 ha) which is located in the reference area of the Tisza Riven Basin. There is limited available water resources at the site, therefore alternative water sources utilization system was set up for irrigation to adapt to climate change and reduce fertilizers. The basis of the alternative water resources are excess water, treated wastewater, biogas fermentation sludge which is collected in a water reservoir with 114000 m3 capacity. For proper irrigation scheduling, heterogeneity of topography, hydrological, soil and crop conditions has to be explored and monitored. Therefore physically-based modelling of the water balance and remote sensing-based surplus water and vegetation status surveying are tested to use for accurate irrigation scheduling. Shallow groundwater and/or soil compaction can also contribute to excess inland water. This may occur even if there are drought periods in a year (e.g. in the Pannonian region), resulting in spots with a low crop yield. A LiDAR-based digital elevation model was found to provide appropriate data to identify sites affected by excess inland water. The spots identified can be used as spatial input data to compile a variable rate irrigation prescription map for imposing reduced (or zero) irrigation at areas more vulnerable to the occurrence of excess inland water. The water balance was also assessed for sites with physically-based models. Hydrus was used to model soil moisture changes at the Hungarian case study site. A model concept for crop evapotranspiration estimation was also developed based on vegetation indices calculated from satellite imagery. Several combinations of sensors and remote sensing products were tested to use in ETc modelling potentially. This approach was tested both at the Hungarian case study sites. Remote sensing-based analysis of crop evapotranspiration, combined with physically-based modelling, appears to be a promising method in water balance modelling of maize fields, especially if these fields are in summer when the crop is fully developed. However, the remotely sensed information verification is essential for the proper utilization of the remote sensing data in ETc modelling and predicting the spatio-temporal dynamics of crop yield, evapotranspiration, and irrigation demands. There is a need further benchmark scenarios to improve both physically-based models and satellite-based crop evapotranspiration models to achieve more accurate and valid simulations.

Cím:Composted sewage sludge utilization in phytostabilization of heavy metals contaminated soils / Attila Nagy, Tamás Magyar, Nikolett Éva Kiss, János Tamás
Dátum:2023
ISSN:1522-6514
Megjegyzések:In phytostabilization, heavy metal-tolerant plants (e.g.,grasses) can be used to reduce the mobility of heavy metals in soils. The most important step in phytostabilization is the selection of the suitable plant species, in which growth and development can be supported by soil amendments. Sewage sludge compost could be a suitable additive, which provides nutrients for the plant species used for phytostabilization and contributes to an alternative solution for sewage sludge utilization. The aim of the study was to examine the potential of sewage sludge compost in phytostabilization for heavy metal contaminated matrices: identify the optimal ratio of sewage sludge compost to decrease phytotoxicity of the matrices, and assessment of feasible plant species for phytostabilization based on its bioaccumulation properties. In this research, perennial ryegrass (Lolium perenne), broad-leaved sorrel sorrel (Rumex acetosa), lettuce (Lactuca sativa) and cabbage (Brassica oleracea var. capitata) were used for phytotoxicity experiments as well as for testing sewage sludge compost amended phytostabilization of polluted flotation sludge and mine tailings. Sewage sludge compost increased the pH and electric conductivity of the matrices. High salt content and low acidity, altogether with heavy metals caused harmful physiological effects on plant species grown without any compost addition. In the root development test, as in the germination test, the application of 5% sewage sludge compost proved to be optimal. The lower translocation factors of broad-leaved sorrel and perennial ryegrass showed a higher rate of heavy metal accumulation in the roots. Perennial ryegrass, cabbage, and lettuce plant species reached their maximum biomass by adding 5% of sewage sludge compost. Based on the bioaccumulation, translocation and biomass properties, application of perennial ryegrass is recommended for phytostabilization of heavy metal contaminated sites. Furthermore, composted sewage sludge also had a significant effect on the reduction of heavy metal uptake by cabbage and lettuce, which highlights their role as indicator plants in ecotoxicological measurements.

Cím:Phytoremediation of acid mine drainage using by-product of lysine fermentation / Nagy Attila, Magyar Tamás, Juhász Csaba, Tamás János
Dátum:2020
ISSN:0273-1223
Megjegyzések:The main point of this research is to assess the applicability of condensed molasses soluble (CMS), which is an organic by-product of lysine fermentation, as an environmentally friendly complexing agent in rhizofiltration of heavy metal contaminated acid mine drainage (AMD). First, the ecotoxicological properties (growth inhibition, seed germination) of CMS were examined with often applied indicator plant species such as duckweed (Lemna minor) and lettuce (Lactuca sativa) so as to define the possible applicable CMS concentration. Then the heavy metal accumulation and translocation properties of root accumulator plant species, i.e. common reed (Phragmites australis) and sedge (Carex flacca), were studied to optimize CMS concentration for rhizofiltration. Due to the CMS application, significant increase in bioaccumulation was detected in the case of every examined heavy metal (As, Cd, Cu, Pb and Zn) at the end of the experiment. Results also showed that CMS increased the heavy metal concentration in shoots, but did not affect the root accumulation characteristics of the plants. Furthermore, CMS treated plants accumulated heavy metals at higher rates in their roots compared to control. The results suggest that CMS is a viable additive and a complexing agent to aid rhizofiltration of heavy metal contaminated AMD.
