Novel microcosm design to test phosphorus desorption from static soil samples using iron oxide-impregnated filter papers.

ABSTRACT: Iron oxide-impregnated filter papers (FeO) facilitate the study of soil phosphorus (P) desorption, availability and dynamics. However, many studies use homogenized and saturated shaking FeO soil systems, hindering opportunities to resolve environmentally relevant experimental objectives. This study created and evaluated a static microcosm to study soil P dynamics with FeO papers. The microcosm design is simple: silicone rubber is glued to the bottom of a piece of polyvinyl chloride (PVC) pipe. The soil is packed to a known bulk density into the PVC pipe. Finally, the top of the PVC pipe is sealed with a fine nylon mesh, allowing water exchange to the overlaying filter paper. To validate the systems, we created three proof-of-concept tests. The first determined whether FeO filter papers rem
