Abstract: Agricultural drainage has been recognized as a major contributor o f excess nitrogen to aquatic ecosystems, especially by allowing the fast release o f nitrate from nitrogen fertilizers.The objective o f this study was to quantify nitrate removal by denitrification in traditionally maintained one-stage and naturalized two-stage agricultural headwater ditches.We measured denitrification rates under field conditions and denitrification potential rates under controlled conditions in the sediments of 10 one-stage and 10 two-stage agricultural drainage ditches in Northwest Ohio USA during summer and fall o f 2003.Water, sediment and plants from both types o f ditches were analyzed to determine chemical and physical characteristics o f the ditches.Denitrification rates and
