Soil phosphorus loss has been historically believed to occur through surface runoff and erosion. However, recent studies have shown that sub-surface runoff or title drainage can account for 22 to 98% of the total soil phosphorus loss. Variation of phosphorus loss in tile drainage water, including seasonality, magnitude, and relative importance to total soil P loss, may be significant. Up-to-date research findings on sub-surface soil phosphorus loss will be discussed in this session.
