Key findings
- On 5 of the 8 sites, considerable concentrations of N or P were mobilised during the simulated rainfall event, but average nutrient concentrations and total loads across all sites were relatively low and similar to other studies of nutrient runoff from pastures.
- Rainfall runoff responses at the sites were similar in the 3 catchments.
- Pastures generated peak nutrient concentrations soon after the commencement of runoff and declined by the end of the rainfall event.
- Due to high to very high infiltration, runoff is not found to be a major pathway for nutrients in the area.
