Electronic Theses and Dissertations
The loss of phosphorus (P) from agricultural soils to surface waters is recognized as a key contributing factor to eutrophication in surface waters. Recent studies have shown that in addition to surface runoff, subsurface drainage can contribute substantially to the loss of P from soils. The use of adsorption materials to bind P has emerged as a promising technology for P removal. The objective of this study was to perform batch and column experiments to investigate the P adsorption potential of several materials for agricultural subsurface drainage treatment. Laboratory batch adsorption experiments were performed to determine the P adsorption capacities …
