Soil properties for any point on Earth
Texture, density, organic carbon, pH, cation exchange and coarse fragments at six depths to 2 m, with USDA texture and water-retention estimates.
Scientific interpretation
1
Particle-size profile with depth
Sand (2–0.05 mm), silt (0.05–0.002 mm) and clay (< 0.002 mm) at the six standard GlobalSoilMap depths. Hover a bar for the value and its 5–95 % prediction interval.
2
USDA texture triangle
Each dot is one depth interval plotted by its sand, silt and clay fractions on the USDA soil texture triangle (Soil Survey Staff, 2017).
3
Chemical and physical properties with depth (mean and 5–95 % range)
Profile table
Water retention by Saxton & Rawls (2006) from sand, clay and organic matter (OM = 1.724 × SOC). Predicted values for screening; confirm with sampling and laboratory tests.
