SERENA EJP SOIL: Soil organic carbon concentration map for the topsoil of Hungary (2016)
Description
The internal EJP SOIL project SERENA contributed to the evaluation of soil multifunctionality aiming at providing assessment tools for land planning and soil policies at different scales. By co-working with relevant stakeholders, the project provided co-developed indicators and associated cookbooks to assess and map them, to report both on soil degradation, soil-based ecosystem services and their bundles, under actual conditions and for climate and land-use changes, at the regional, national, and European scales.
The data was prepared according to the methodology of SERENA SOC loss cookbook for the territory of Hungary. To compile the soil organic carbon map, soil organic carbon (0-30 cm, year 2016) data of the Hungarian Soil Information and Monitoring System (SIMS) were used, which are not publicly available. The selection of environmental covariates, which are then used to model and map SOC content, was based on the ‘scorpan’ model: (s) soil properties, (c) climate, (o) organisms, (r) relief, (p) parent material, (a) age and (n) spatial coordinates. The following covariates were used: soil type map of Hungary (Pásztor et al., 2018); long-term mean annual evapotranspiration, -evaporation, -precipitation, and -temperature (Szentimrey et al., 2007); CORINE Land Cover 2012; EU-DEM and derivatives; Geological map of Hungary (Gyalog & Síkhegyi, 2005). Random forest kriging (RFK, combination of the random forest machine learning algorithm and the kriging technique) was used for the prediction of the SOC concentration.
Notes
The data are derived from the calculation of indicators based on a standard methodology established as part of the EJP Soil SERENA programme. Please keep in mind that:
- It is the result of a modelling exercise and does not necessarily reflect reality.
- Despite the efforts made to provide reliable data, the results may contain inconsistencies, depending in particular on the raw data available and level of accuracy of the techniques chosen and their prior knowledge.
- It is necessary to consider how the results have been obtained in order to decide on their relevance in relation to the intended purpose of reuse.
- These results are interesting from a scientific point of view, but their use for environmental management and policy issues should be done keeping the previous aspects in mind and complementing when necessary the provided results with the best available data.
Finally, it is the responsibility of the users of this information to decide whether it is appropriate to use these data and whether the data meet their needs. The authors of this resource can in no way be held responsible for the results obtained from the use of this data.
