Modeling the impact of ferrihydrite on adsorption-desorption of soil phosphorus

Ferrihydrite is an Fe-oxide mineral with a high phosphorus (P) sorption capacity. Modeling the P adsorption and desorption mechanisms of soil amended with ferrihydrite is necessary to predict the movement of dissolved and sediment-bound P. The objective of this study was to model the multi-reaction...

Zusammenfassung:	Ferrihydrite is an Fe-oxide mineral with a high phosphorus (P) sorption capacity. Modeling the P adsorption and desorption mechanisms of soil amended with ferrihydrite is necessary to predict the movement of dissolved and sediment-bound P. The objective of this study was to model the multi-reaction P sorption properties of soil amended with ferrihydrite. Soil samples were treated with 0, 6.72, and 11.20 Mg ha-1 of ferrihydrite. The
