Short Description of your Research or Creative Project (700 characters or less)

Plant available phosphorus (P) occurs in anionic forms which become plant-unavailable ("fixed" or "retained") when iron and aluminum oxides form insoluble phosphate complexes. P-retention is especially likely to occur under acid conditions in soils containing short range order (SRO; poorly crystalline) materials, namely allophane and imogolite. This set of characteristics is common in volcanic-derived forest soils in Pacific Northwest timber regions. We built upon 25 years of research by investigating phosphorus retention on two well-studied sites, Whitmore and Feather Falls. Simple soil assays were used in a mixed-effects model to predict P-retention on these soils.
