Few watershed-scale studies have evaluated phosphorus export in streamflow from commercial poultry-pasture operations. Continuous streamflow and mixed-frequency water quality datasets were collected from nine commercial poultry-pasture (AG) and three forested (FORS) headwater streams (2.4-44ha) in the upper Etowah River basin of Georgia to estimate total P (TP) loads and examine variability of hydrologic response and water quality of storm and nonstorm-flow regimes. Data collection duration ranged from 18 to 22months, and approximately 1,600 water quality samples were collected. Significant (p<0.1) inverse relationships were detected between peak flow response variables and both drainage area and fraction of forest cover. Order-of-magnitude differences in TP and dissolved reactive P (DRP) concentration were observed between AG and FORS sites and among AG sites. TP yields of FORS sites ranged from 0.01 to 0.1kg P/ha. Yields of AG sites ranged from 0.031 to 3.17kg P/ha (median=0.354kg P/ha). With 95% confidence intervals, AG yields ranged from 0.025 to 13.1kg P/ha. These small-watershed-scale yields were similar to field-scale yields measured in other studies in other regions. TP yields were significantly related to area-weighted Mehlich-1 soil test P concentrations (p=0.0073) and base-flow water sample P concentrations (p≤0.0005). Water quality sampling during base-flow conditions may be a useful screening tool for P risk-based management programs. © 2011 American Water Resources Association. |
