Tillage practices can affect the formation and persistence of preferential flow paths and their role in transporting portion of the surface applied chemicals to groundwater. Field experiments were conducted to quantify tillage (chisel, moldboard, ridge and no-till) effects on subsurface drain flow and losses of nitrate-nitrogen (NO
