Cím:Characteristics of chernozem soil in a long term field experiment in Hungary / Balláné Kovács Andrea, Kátai János, Juhász Evelin, Nagy János, Rátonyi Tamás
Dátum:2019
ISSN:2066-6276 2601-5676
Megjegyzések:The polyfactorial long-term field experiment was conducted in 1983 on a calcareous chernozem soil in Hungary (Debrecen-Látókép experimental farm) to determine the long-term effect of different doses of chemical fertilizers and irrigation on the yield, nutrient uptake of maise (in monoculture production) and on soil parameters. Our aim was to analyse and compare the changes of soil chemical and microbiological caracteristics for 33 years NPK fertilizer application either in irrigated and or in non irrigated version. Soil pH, humus, nutrient content and some soil microbiological parameters were analyzed. The microbiological parameters sightly, the chemical parameters of soil significantly influenced by long term application of NPK fertilizers. In fertilized plots: the pH decreased, humus content increased. The availability of supplied nutrients, NPK improved, while non-supplied macronutrients, calcium and magnesium significantly decreased in fertilized plots compared to control. The significantly decrease in calcium content call attention, that the same effect in acidic sandy soil might be particularly harmful. In fertilized plots the number of bacteria tended to decrease, while the number of microscopic fungi and saccharase enzime activity significantly enhanced. The irrigation did not cause significant changes of measured microbiological parameters.

Cím:Possible Environmental Aspects of Thermal Water Utilisation in North East Hungary / Buday-Bódi Erika, Buday Tamás, Magyar Tamás, Molnár Levente, Tamás János
Dátum:2019
ISSN:2066-6276 2601-5676
Megjegyzések:The reserves and exploitation of conventional, so-called fossil energy resources are limited, therefore the utilisation of renewable energy resources has been becoming more and more important. Present study focuses on the thermal water utilisation possibilities i.e. energy content utilisation, balneological utilisation, irrigation, and the related environmental aspects in North East part of Hungary. Among the environmental effects the total dissolved solid concentration and the methane and carbon dioxide content are examined through the examples of 66 thermal water wells screened into pannonian sensu lato (s.l). succession. Thermal water utilisation may have many various environmental aspects: chemical impacts, gas emission, thermal effects, water quality effects noise effects, landscape change, from which methane and solids dissolved in thermal water emitted by its extraction are highlighted. Considering that the annual thermal water extraction from reservoirs located in the Northern part of the Great Hungarian Plain the annual Total dissolved solid concentration (TDS) and methane production can be estimated as 28,207 tones and 1,671,482 m3, respectively. It must be highlighted that by applying cascade systems, the efficiency of thermal water utilisation can be improved while environmental aspects do not increase considerably.

Megjegyzések:Rapid weather fluctuations with an increasing demand for resource use impacts crop production sustainability leading to severe use of land and water resources. Laboratory analysis and technological improvements, such as remote sensing, generate new information and knowledge, to ease the visibility of effects by agricultural practices, bringing new opportunities to better use resources and improve farming sustainability and water management practices. Irrigation use and assessment are important to assure the sustainability; planning and modelling based on soil-plant economy relationship by the use of technological innovation, as Lidar imagery, enhancing the precision to large scale knowledge gained a plot-farm level. Agronomics, agriculture engineers, management technologies aim to reduce non-productive water use in agriculture. Finding the correlation between soil water retention and physical parameters contributes to irrigation management plant, therefore, reducing water use, cutting costs for agri-food production and reducing environmental impact. Soil sampling is performed in two depth and analysis of soil physical and water retention parameters with the correlation of LiDAR survey proving in-depth on-field information. Silt-loamy texture makes a good texture, water retention capacity. A decrease of silt content in the upper layer (6.4 %), an increase of sand and clay (7 % and 28 %) respectively. Conventional soil cultivation made an impact on the soil upper layer. Soil water retention did not show the major fluctuation of two layers regarding pF values. LiDAR results shown the area is not susceptible to erosion, 68 % is in the 1 st slope category and 28 % in the 2 nd. LiDAR, clear understanding and visualisation of site laboratory data for different. The field is well drained, vegetation period and cultivation could require scheduled, separated irrigation on land based on DEM and runoff lines helping to improve irrigation planning and water use efficiency. Demonstration the benefits of using high accuracy remote sensing LiDAR data, preventing water logging, misuse, and improve irrigation management and shows good examples to use in large scale to ease comprehensive understating of data.

Cím:The role of green manure in Hungarian crop production / Fekete Ágnes, Pepó Péter
Dátum:2017
Megjegyzések:According to the data of KSH (Hungarian Central Statistical Office) sowing area of cereals in the crop year 2016 was over 2.56 million ha, on which winter wheat and maize were produced in a rate of around 50-50%. Regarding these data it is obvious that the domestic sowing structure has been simplified and become unilateral. This unfavourable crop rotation system causes several problems. Due to the unilateral plant production soil conditions may deteriorate, several nutrient supply, plant protection and water supply problems may occur. It has to be added that the number of Hungarian livestock decreased in the past decades. Amount of manure was 24 million tons in 1960, but only hardly 4.5 million tons of organic manure was applied in 2016. According to the data of the Research Institute of Agricultural Economics it can be stated that the production area of green manure crops was less than 40 000 hectares before 2015, but after the introduction of the new subsidiary system their sowing area was doubled in Hungary. The targeted sowing area of green manure crops in 2017 was over 86 000, 26 000 ha of which was planned to be sown in the Southern Great Plain region (AKI 2013, 2017). There are several methods for the recovery of organic matter. One is if plant organic substances and by-products are tilled into the soil, the other is if different green manure crop species and/or their mixture are sown directly.

Cím:Identification of inland-excess water patches based on LIDAR and Sentinel 1 data / Gálya Bernadett, Nagy Attila, Juhász Csaba, Riczu Péter, Szabó Andrea, Blaskó Lajos, Tamás Janos
Dátum:2020
ISSN:2066-6276 2601-5676
Megjegyzések:Understanding the habitat is essential for economic production. As a result of rapidly changing processes, features of habitats may be modified, it may be affected by a wide variety of factors. Inundation caused by inland-excess water (IEW) is one of the most significant natural disasters but spatial and temporal targeting of it is also a problem in practice. Over half of Hungary's territory is endangered by IEW. For the development of inland-excess waters a combination of several adverse natural and human activity is highly important. The formation of IEW is primarily determined by meteorological, soil and terrain conditions. During the research, the causes of the development of IEW were analysed based on the terrain conditions of the area in a grassland. Soil connections have been well explored according to the other studies, but not as terrain causes. Therefore the applicability of digital elevation models based on remote sensing (high density LiDAR) data and Sentinel 1 data in inland areas is a priority area of our research. To examine the relief, elevation data of conventional analog topographic maps with 1:10000 scale and an aerial LiDAR data were compared. Sentinel 1 data were used to validate the results based on the LiDAR data. Based on digital elevation model (DEM) derived from topographical map shows that there is no risk of IEW on the grassland. It is, however, contradicted by the reality, the inland marshes presents on grassland land during on-site visits and which can be identified by the LiDAR and Sentinel 1 images.

Cím:Water retention possibilities in soils - Hungarian part of tisza-river basin / Gálya Bernadett, Tamás János, Blaskó Lajos, Riczu Péter, Nistor Stelian, Fehér János, Bozsik Éva, Nagy Attila
Dátum:2018
Megjegyzések:In many regions of Europe (among others in Hungary) agricultural production has been affected by droughts over the past decades. Global Water Partnership (GWP) Central and Eastern Europe (CEE) wanted to supported European countries in developing of an early warning system,which consists of monitoring, prediction and combine national drought policies. In order to use risk assessment ? in which prevention of drought is emphasized - available water content calculation of watershed should be prepared for drought impacted areas. The aim of our study was to create a highresolution, trans - border database, which takes into account the most important water regime properties of soils and it can be uniformly used in other countries of Tisza River Basin. Based on traditional soil maps, a soil database was created, where soil water content - in 2m layer depth of soil - can be estimated for different horizons and for different soil types. First of all, digital soil maps of different countries were adjusted to WRB (World Reference Base for Soil Resources), and calculation mapping was worked out for the total area of the Tisza River Basin. After allocations of the soil layers, physical limit values of soils were estimated by using pedo-transfer functions. Water storage capacity and available water content were determined by the depth of the impermeable layer. Finally, spatial queries were carried out in the Tisza River Basin and in units of administration. These data were integrated into a geographic information system, in which the data clearly showed that the impact of drought was more severe in extreme water management soils. In case of large-scale longterm droughts, local differences decreased the reliability of the calculations to a lesser degree.However, with further methodological development, the effect of these local differences can be reduced.

Megjegyzések:Composting is one of the most popular recycling processes for organic waste. Compost is an inherently variable product produced from a wide variety of organic source materials known as feedstocks. The aim of our research was to examine the process of composting with maturity and stability parameters. The windrow composting experiments were set up in the composting area of the University of Debrecen, Institute for Water and Environmental Management and a mixture of broiler and hen manure was composted by adding zeolite (0, 1, 2, 5, 7 w/w %). The time for composting experiments was 62 days. We continuously measured the main parameters describing the composting processes: moisture content (w/w %), temperature (?C), pH, electrical conductivity (mS/cm), organic matter content (w/ w%). Based on our results, it can be concluded that the 50 w/w % moisture content is sufficient for composting in the case of the mixtures of substances tested by us. The four stages of composting can be separated by temperature, and the thermophilic phase is longer with increasing zeolite mixing. The value of pH ranged from pH 6.63 to 8.0, with lower pH values at the beginning and neutral at the end of the composting process. Electrical conductivity values decreased at the end of the composting process. Adding a higher percentage of zeolite reduced the content of organic matter, thereby increasing the mineral content. Overall, the parameters studied by us are suitable for determining the maturity of compost and for describing the composting process.

Cím:Evaluation of sweet sorghum (Sorghum bicolor) hybrids as bioenergy feedstocks in relation to climatic aspects / Jóvér János, Kovács Györgyi, Blaskó Lajos, Juhász Csaba, Kovács Elza
Dátum:2020
ISSN:2066-6276 2601-5676
Megjegyzések:In this study, biomass yield and sugar content, and bioethanol potential of six sweet sorghum hybrids were considered to assess the potential role of the genotype in the performance of sorghum. Yield and sugar content values were investigated in relation to the climatic aspects according to the Ellenberg and the Pálfai drought indices, and the effect of drought on biomass yield and sugar content was evaluated to reveal the dominant factor determining the bioethanol yield. Results proved that sweet sorghum holds a significant potential in the semi-arid regions to enhance the amount of the produced bioethanol e.g. in the EU, even though, considering the climatic characteristics of each year, sometimes extreme differences have been found that had a significant impact on its production. However, considering the performance of the hybrids, significant differences were found for both the green yield (5.5 t ha-1) and the sugar content (0.79 Brix %) under similar weather conditions, but sugar content for any of the selected hybrids had no relationship with the drought indices, though, seasonal impact was proved. In contrary, biomass yield showed significant relationship with the Pálfai drought index, suggesting that annual water shortage results in lower sorghum yield in the investigated semi-arid region as the determinative factor. Hybrids of the sweet sorghum showed high but different biofuel potential under the same, extreme climatic conditions via their biomass production variation, thus their field specific experimental testing is advisable to find the best performing ones in this context.

Dátum:2019
ISSN:2066-6276 2601-5676
Megjegyzések:In order to reach the goal determined by the 2009/28/EU directive sorghum production for energy purposes can be an adequate method. Efficient sorghum production is based on the consideration of the climatic aspects. An advantage of sorghum is appearing in the field of drought tolerance. The foundation of sorghum's great drought tolerance is the high heat demand which must be fulfilled. The heat demand varies from 8 ?C to 15 ?C, so that based on the meteorological data recorded in the period of 1997-2016 the Effective Heat Unit varied between 627 ?C and 2097 ?C. Base temperature has a remarkable impact on the length of the vegetation period as well. Depending on this value the potential length of the vegetation period can vary from 123 days to 153 days. The sugar accumulation curve of a sorghum hybrid is also an important aspect of efficient bioethanol production where length of the vegetation period is an essential factor.

Cím:Life cycle assessment of the environmental impact of broiler chicken production / Kiss Nikolett Éva, Tamás János, Nagy Attila
Dátum:2022
ISSN:2066-6276 2601-5676
Megjegyzések:The environmental impacts of broiler chicken production are becoming increasingly relevant as the industry grows in importance. A suitable method for assessing the environmental impact of a process is life cycle assessment (ISO 14040:2006). A life cycle assessment of a broiler chicken farm in Hungary was conducted in this study, which compared the emissions of summer and winter rotations. The environmental burden was represented by five impact categories: acidification potential (AP), eutrophication potential (EP), global warming potential (GWP), ozone depletion potential (ODP) and human toxicity potential (HTP). The study's aim was to compare emissions between summer and winter rotations, as well as to identify and assess the most critical points in broiler chicken production. The results demonstrated that there is no substantial difference in emissions between winter and summer rotations for AP, EP, and HTP, however values for GWP and ODP impact categories are 10-10% higher in winter months. The higher value is attributable to the increased use of natural gas in the winter. When the critical points were examined, the feed-related processes were the ones that contribute the most to the impact categories.
