THE EFFECT OF SUBSURFACE DRAINAGE ON WATER QUALITY FROM SOYBEANSPublished by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org Citation: Paper number 701P0304, . (doi: 10.13031/2013.15721)Authors: R.L. Bengtson and C.E. Carter Keywords: Runoff, Soil Erosion, Nitrogen, Phosphorus Sediment and nutrient losses were measured from a subsurface drainage-runoff-erosion experiment for the years 1988 to 2000. The experiment, located near Baton Rouge, Louisiana, consisted of five surface-drained plots, three of which were also subsurface drained. Subsurface drainage reduced surface runoff by 29%, soil loss by 44%, nitrogen loss by 33%, phosphorus loss by 29%, and potassium loss by 29%. (Download PDF) (Export to EndNotes)
