Abstract: Soil property data represent the key input for the process of hydrological modelling. Purposive sampling of the catchment is both time and money consuming. Therefore, global or legacy data are frequently applied. The study compares the use of the SoilGrids global map and the map originating from legacy data for hydrological modelling. The research work was carried out using the SWAT model for the Olesna catchment (the area of 33 km(2)). The SoilGrids dataset generally shows the finer soil texture and the higher organic carbon content than the dataset based on local legacy data. This fact results in worse prediction of nitrate loading by the SoilGrids model.
