Distributions of modelled topsoil SOC concentrations for each map plotted as combined boxplots and violin plots (outliers in red), with coloured shading of the plot background denoting mineral (0–44 g kg−1), humus-mineral (44–165 g kg−1), organo-mineral (165–330 g kg−1) and organic (330–550 g kg−1) soils.
