• High-resolution soil maps are important for land use planning, agriculture crop production, forest management, hydrological analysis and environmental protection. In this work, we consider the analysis of soil texture samples in the Basque Country (i.e. the relative proportions of sand, silt, or clay in soil) and use covariate information to predict a high-resolution soil map. We propose the use of geo-additive models for modelling and predicting the spatial distribution of soil texture in a Bayesian framework for compositional data.
