Key Points

To establish an environmental soil phosphorus threshold based on clay content to evaluate and mitigate the risk of phosphorus transfer to aquatic systems.
Evaluated soil phosphorus availability and retention in regional soils from Rio Grande do Sul, Brazil.
Modeled environmental phosphorus threshold values using soil clay content as the primary predictive variable.
Identified that soil phosphorus retention capacity varies significantly as a function of soil clay concentration.
Established an environmental threshold index to classify soils according to their vulnerability to phosphorus loss and subsequent water body eutrophication.
