3D soil parameter space of the agricultural landscape [Germany, Version 2]

The national-scale evaluation and modelling of the impact of agricultural management and climate change on soils, crop growth, and the environment require soil information at a spatial resolution addressing individual agricultural fields. The agglomeration of the soil parameter space into a limited number of functional soil process units (SPUs) allows for reducing the required resources to run agricultural process models without having to cut back on the spatial resolution. To serve these needs, this data product was developed with a data science approach.
The agricultural soil-landscape of Germany is represented by 20 SPUs. Each SPU is described by a multivariate parameter distribution along its depth profile. The data product refers to the parameter space until a depth of 1 m. It has a 100 m raster resolution in the 2D mapping space, and its resolution along the depth profile is 1 cm. It includes the soil properties: particle size distribution (sand, silt, and clay content), stone content, bulk density, occurrence of stagnic and gleyic properties, total organic carbon content, and pH value.
The data product consists of two files: A nationwide raster (SPU.tif) indicating the spatial allocation of the SPUs in terms of an identifier variable, and one related table (MPD.csv) including the information of the multivariate parameter distributions of the SPUs. The table is linked to the raster by the identifier.
