Sediment-Associated Phosphorus in Drainage Features in Southeastern North Carolina

Record #:
Drainage features, such as natural streams and man-made ditches, provide pathways for nutrients and other materials from land to surface waters. The authors compared agricultural areas with other land cover types as sources of sediment-associated phosphorus in drainage features. Sample sites were chosen to include roadside ditches along agricultural fields, near livestock operations, residential areas, forested and other undeveloped areas. Several natural streams were also selected. Results indicate that agricultural activities can contribute significantly to sediment phosphorus loads in drainage features.
