Global patterns and drivers of soil total phosphorus concentration
Soil represents the largest phosphorus (P) stock in terrestrial ecosystems. Determining the amount of soil P is a critical first step in identifying sites where ecosystem functioning is potentially limited by soil P availability. However, global patterns and predictors of soil total P concentration...

Soil represents the largest phosphorus (P) stock in terrestrial ecosystems.
