While SoilGrids is an important source of soil property data for a wide range of
environmental studies worldwide, there is currently an extreme lack of studies evaluating its
accuracy against independent ground truth soil sampling data. This study aimed to provide a
comprehensive insight into the accuracy of SoilGrids layers for three physical soil properties
representing soil texture components (clay, silt, and sand soil contents) using ground truth
data in the heterogeneous landscape of Croatia. These ground truth data consisted of 686 …
