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.

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.

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.

Cím:	The influence of base temperature on sweet sorghum production in Hungary / Jóvér János, Blaskó Lajos, Kovács Györgyi, Tamás János

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.
