N2  - Leaching of agrichemicals into subsurface tile drainage water is a concern for water quality. Nitrate in drainage water is also an economic loss to producers beside its enviromnental problems. A field experiment was conducted to study the transport of nitrtate and atrazine (a herbicide) through a clay soil of Nile Delta (Fuwwa district), and to evaluate their losses into subsurface tile drains of different spacings (30 m and 60 m). Corn was planted on the experimental site. A total of 120 Kg N/fed as urea and 0.75 Kg/fed of atrazine was applied to the soil during cultivation. Daily water table depths and drain flow rates were determined.  Key words: Atrazine, nitrate, drain spacing, discharge rate, preferential flow, corn yield, N uptake
