Abstract: The measured soil profile data of the Hydraulic Properties of European Soils (HYPRES) were evaluated for their potential use in extending the geographic coverage and thematic range of the profiles of the Soil Profile Analytical Database of Europe of measured profiles (SPADE/M) database. The aim of increasing the number of measured profiles is to improve the definition of pedo-transfer rules (PTRs) to extend the range of parameters characterizing soils and the validation of model runs. The HYPRES and SPADE/M databases follow different concepts in the compilation of soil profiles. These differences were reflected in the organization of storing profile data in the databases. A specific conceptual problem to extending the SPADE/M data set is posed by recording repeated measurements in the HYPRES database for horizons of a profile and multiple profiles for a plot. The two data sets also differ with respect to the properties recorded, the measurement units and the database model. To increase the number of measured soil profile data of the SPADE/M data set with HYPRES profiles the data from the latter has to be standardized to be adjusted to comply with the specifications of the SPADE/M data set. The standardization process involves conversions of units or reference systems, such as the plot co-ordinate transformation or the extraction of properties from comment fields, but also conceptual adaptations of the method used to characterize a soil horizon in the database. The outcome of the standardization process is a series of soil profiles which can be seamlessly added to the SPADE/M data set.
