Abstract. Spatial 3-D information on soil hydraulic properties for areas larger than plot scale is usually derived using indirect methods such as pedotransfer functions (PTFs) due to the lack of measured them. PTFs describe relationship between desired parameter and easily available based a reference dataset. Soil catchment or region can be calculated by applying maps. Our aim was analyse performance (i) (using PTFs) (ii) direct (geostatistical) mapping derive properties. The study performed...
Abstract Questions Multiple potential natural vegetation ( MPNV ) is a framework for the probabilistic and multilayer representation of in an area. How can model be implemented synthesized full range types across large spatial domain such as country? What additional ecological practical information gained compared to traditional PNV estimates? Location Hungary. Methods was estimated by modelling occurrence probabilities individual using gradient boosting models GBM ). Vegetation data from...
We compiled maps for the topsoil (0–30 cm) organic carbon (SOC) stock and its prediction uncertainty in Hungary at 100 m resolution years 1992 2010 using a machine learning algorithm, namely, quantile regression forest. 10-fold cross-validation was used checking accuracy of spatial predictions quantifications both years. The performance appropriate, which verified by computed biases (0.15 0.30 2010), root mean square errors (21.99 21.39 plots G statistics (0.96 years) as well. Based on SOC...
Stakeholders and policymakers have been becoming more interested not just in the potential organic carbon (SOC) saturation level of soils but also spatially explicit information on degree SOC deficit, which can support future policy sustainable management strategies, sequestration-associated spatial planning. Thus objective our study was to develop a cubist-based pedotransfer function (PTF) for predicting mapping saturated content topsoils (0–30 cm) Hungary then compare resulting map with...
Spatially explicit, quantitative information on soil hydraulic properties is required in various modelling schemes. At European scale, EU-SoilHydroGrids proved its applicability a number of studies, ecological predictions, geological and hydrological hazard assessment, agri-environmental models, among others. Inspired by continental antecedent, an analogous, but larger national, 3D database was elaborated for the territory Hungary (HU-SoilHydroGrids) supported improvements (i–iv) computation...
Abstract Since soil spectroscopy is considered to be a fast, simple, accurate and non-destructive analytical method, its application can integrated with wet analysis as an alternative. Therefore, development of national-level spectral libraries containing information about all types represented in country continuously increasing serve basis for calibrated predictive models capable assessing physical chemical parameters soils at multiple spatial scales. In this article, we present database...
The introduction of the Directive on Soil Monitoring and Resilience proposed by European Parliament Council is supposed to be preceded specific preparatory works at Member State level, such as definition so-called soil districts together with development a monitoring system based elaborated zonalization. Three subsequent terms Presidency Union (Belgian, Hungarian, Polish) aimed finalize concept elaboration legislate Directive, so far without success. As consequence, final delineation could...
The ability of soil to store a large amount organic carbon (SOC) is one its most important characteristics, making it an active and indispensable participant in the global cycle. SOC influences various related functions services, such as agricultural productivity, water retention management, buffering capacity against toxic elements compounds, which are essential provide healthy food clean drinking water. Furthermore, widely recognized playing crucial role mitigating addressing environmental...
Understanding soil water management properties is crucial for agricultural, hydrological, and environmental modelling. To enhance the description of hydraulic processes, we developed national 3D maps Hungary at 100 m resolution, covering six layers down to 2 depth (HU-SoilHydroGrids). This dataset includes continuous values calculated parameters, but aggregating this information necessary facilitate its use in large-scale hydrological models with significant computational demands.In Hungary,...
Determining soil parameters is essential for rational use, sustainable management, cost-effective monitoring, and collecting baseline data targeted mapping.The aim of our research to perform non-destructive spectroradiometric measurements on the archived sample bank HUN-REN ATK Institute Soil Sciences, which includes comprehensive laboratory background data. This initiative seeks develop a nationwide spectrum library that spatially represents entirety Hungary’s land cover types,...
Spatially detailed quantitative data regarding soil physical/hydraulic properties is in high demand for a range of modeling applications. EU-SoilHydroGrids has demonstrated its utility at the European level. HU-SoilHydroGrids, been developed whole area Hungary 100 m spatial resolution with several enhancements elaboration process. A further step toward larger based on NATASA (Hungarian acronym Profile-level Database Hungarian Large-Scale Soil Mapping) initiative to produce large-scale 3D...
The constant and detailed monitoring of soil properties is crucial for having an up-to-date status the health our soils. This requires sufficient sampling points to meaningfully accurately represent soils a whole country. Topsoil datasets can be very different regarding point density, spatial distribution representativity. Soil also cost- labour-intensive, which why combining existing national international efficient way create larger creation accurate property maps. In case Hungary, these...
The GlobalSoilMap initiative significantly inspired the DOSoReMI.hu (Digital, Optimized, Soil Related Maps and Information in Hungary) project, which was started intentionally for renewal of national spatial soil data infrastructure Hungary. main objectives our work has been to broaden possibilities, how demands on related information could be satisfied Hungary, gaps between available expected filled with optimized digital (related) maps. During activities, we have extended potential,...
High-resolution ecosystem maps increase the efficiency of policy implementation. However, due to challenges related both data and methods, such appropriate scale quality are still rarely available for nationwide analyses. We present solutions some typical national-scale mapping through new Ecosystem Map Hungary. It is a comprehensive, spatially thematically detailed map with hierarchical typology. The methodology combined several novel elements from integration various large-scale databases...
Due to former soil surveys and mapping activities significant amount of information has accumulated in Hungary. Present data requirements are mainly fulfilled with these available datasets either by their direct usage or after certain specific generally fortuitous, thematic and/or spatial inference. the more frequently emerging discrepancies between expected data, there might be notable imperfection as for accuracy reliability delivered products. With a recently started project we would like...
Recently, the Global Map of Salt-affected Soils (GSSmap) was launched, which pursued a country-driven approach and aimed to update global country-level information on salt-affected soils (SAS). The aim this paper present how Hungary contributed GSSmap by preparing its own SAS maps using advanced digital soil mapping techniques. We used not just combination random forest multivariate geostatistical techniques for predicting spatial distribution indicators (i.e., pH, electrical conductivity...
Gridded model assessments require at least one climatic and soil database for carrying out the simulations. There are several parallel climate development projects that provide sufficient, albeit considerably different, observation based input data crop impact studies. The related uncertainty of Biome-BGCMuSo agro-environmental outputs was investigated using three four different gridded databases, respectively covering an area nearly 100.000 km2 with 1104 grid cells. Spatial, temporal,...
