My research aims to explore the variability of phosphorus (P) concentration, load, and delivery in different hydrologic pathways at different spatiotemporal scales.  Three scales of hydrologic pathways are being explored: 1) hillslope (<2 ha), 2) small watershed (2-44 ha), and 3) medium to large watershed (103 - 107 ha).  At each scale, the variability of P in the predominant hydrologic pathway(s) will be characterized and related to factors that are relevant to the scale of interest.  While it is not a direct focus of my research, an underlying question will be to determine if or how any relationships involving hydrologic transfer of P are related (i.e. linearly) across scales.  My research is constrained to watershed systems in Georgia, USA.  Emphasis is placed on first-order streams in the upper Etowah River basin in north-central Georgia that drain predominantly agricultural (i.e. cattle-grazed pasture and/or pasture receiving poultry litter fertilizer) or forested watersheds.
