Abstract:

Sediment and nutrient losses were measured from a subsurface drainage-runoff-erosion experiment for the years 1981 to 1984. The experiment, located near Baton Rouge, Louisiana, consisted of four surface drained plots, two of which were also subsurface drained. The plots were uniformly graded to a 0. 1% slope and contained a clay loam alluvial soil. Subsurface drainage reduced surface runoff by 33%, soil loss by 21%, nitrogen loss by 23%, phosphorus loss by 33%, and potassium loss by 29%.
