<abstract>Conservation agriculture, especially no‐tillage, has proven to become sustainable farming in many agricultural environments globally. In spite of advantages of no‐till systems, this practice may result in excess infiltration into the soil and can enhance the movement of mobile nutrients and some pesticides to subsurface drains and groundwater along preferential pathways.

The RRMSE, AAD and R² for the validation period were determined to be 1.09, 1.85 and 0.83 mm for drain outflow, and 1.43, 0.51 and 0.79 mg l⁻¹ for NO₃‐N concentration respectively. The results showed that DRAINMOD‐N II predicted NO₃‐N leaching reasonably well in drainage outflow of no‐till fields over the whole period.
