Abstract

Studies both the long-lasting effects of a single water treatment residuals-biosolids co-application and the short-term impacts of a repeated application on soil phosphorus dynamics. Determines the rate of biosolids phosphorus mineralization, which organic or inorganic phosphorus pools dominate phosphorus equilibrium, and shifts between these pools over time under co-application conditions.
