Figure 4

Patterns of soil δ15N with soil C and N concentrations.

Relationships between (A,D) soil carbon concentrations, (B,E) soil nitrogen concentrations and (C,F) soil C:N with soil δ15N for (A–C) mineral soils and (D–F) mineral as well as organic soil horizons. For (A–C), each point represents soils averaged for 0.1° latitude and longitude. All relationships significant at P < 0.001.
