Standard color palettes for soil properties and classes that can be used to display global soil data.
1 |
Contains a list of color palettes (data frames with class names / break points, and cumulative probabilities) for:
ORCDRC
numeric; soil organic carbon content in permille
PHIHOX
numeric; pH index measured in water solution
PHIKCL
numeric; pH index measured in KCl solution
BLDFIE
numeric; bulk density (fine earth) in kg per cubic meter
CECSOL
numeric; Cation Exchange Capacity of soil
SNDPPT
numeric; weight percentage of the sand particles (0.05–2 mm)
SLTPPT
numeric; weight percentage of the silt particles (0.0002–0.05 mm)
CLYPPT
numeric; weight percentage of the clay particles (<0.0002 mm)
CRFVOL
numeric; volumetric percentage of coarse fragments (>2 mm)
TAXOUSDA
factor; Keys to Soil Taxonomy suborders
TAXGWRB
factor; World Reference Base groups
TAXNWRB
factor; World Reference Base legend for SoilGrids250m
Breaks for continuous soil properties were determined using the quantiles
function and by visually inspecting the histograms to maximize the contrast in output maps. Based on a compilation of global soil profile data (see ISRIC's World Soil Information Service WoSIS).
