Extended Data Figure 1: Relationships between aridity and the concentration of inorganic P and the ratios of total N to inorganic P and organic C to inorganic P at our study sites.
From: Decoupling of soil nutrient cycles as a function of aridity in global drylands
Inorganic P, sum of Olsen inorganic P and HCl-P. The solid and dashed lines represent the fitted quadratic regressions and their 95% confidence intervals, respectively.
