Figure 5. Relationships between soil carbon concentrations and texture.

Shown are the percentages of (A,D) sand, (B,E) silt, and (C,F) clay vs. (A–C) soil carbon (mg g⁻¹) as well as (D–F) residual log₁₀-transformed soil carbon (mg g⁻¹) after accounting for MAT, log₁₀MAP, and average depth. All points represent soil values averaged to 0.1° latitude and longitude.
