Phosphorus dynamics in tile-drain flow during storms in the US Midwest

▶ For large storms (>6 cm), macropore flow regulated SRP export. ▶ For small storms (<3 cm), matrix flow regulated SRP export. ▶ Macropore flow regulated TP export regardless of the storm. ▶ SRP accounted for 9–22% of TP flux in tile-drains. Excess phosphorus (P) in freshwater systems has been...
