Evidence & Context
The total phosphorus (Total P) concentrations in the topsoil (0-30 cm) of these younger, vegetated systems provide a robust baseline for the natural P capital of a healthy system: 36.7 to 62.0 mg/kg Total P.
Total phosphorus concentration in topsoil (0-30 cm) representing the long-term P capital of the site.
This benchmark represents the natural range of total phosphorus stock in the topsoil of developing productive subtropical forests on low phosphorus buffering sandy soils.
Represents the P stock in a developing, productive subtropical forest on low-PBI sandy soils.
