LUCAS Topsoil Survey: methodology, data and results In 2009, the European Commission extended the periodic Land Use/Land Cover Area Frame Survey (LUCAS) to sample and analyse the main properties of topsoil in 23 Member States of the European Union (EU). This topsoil survey represents the first attempt to build a consistent spatial database of the soil cover across The EU based on standard sampling and analytical procedures, with the analysis of all soil samples being carried out in a single laboratory. Approximately 20,000 points were selected out of the main LUCAS grid for the collection of soil samples. A standardised sampling procedure was used to collect around 0.5 kg of topsoil. The samples were dispatched to a central laboratory for physical and chemical analyses. Subsequently, Malta and Cyprus provided soil samples even though the main LUCAS survey was not carried on their territories. Cyprus has adapted the sampling methodology of LUCAS-Topsoil for (the southern part of the island) while Malta adjusted its national sampling grid to correspond to the LUCAS standards. Bulgaria and Romania have been sampled in 2012. However, the analysis is ongoing and the results are not included in this report.The final database contains 19,967 geo-referenced samples. This report provides a detailed insight to the design and methodology of the data collection and laboratory analysis. All samples have been analysed for the percentage of coarse fragments, particle size distribution (% clay, silt and sand content), pH (in CaCl2 and H2O), organic carbon (g/kg), carbonate content (g/kg), phosphorous content (mg/kg), total nitrogen content (g/kg), extractable potassium content (mg/kg), cation exchange capacity (cmol(+)/kg) and multispectral properties.
