Comparison of the performances of DRAINMOD-NII and ADAPT models in simulating nitrate losses from subsurface drainage systems.

Highlights: [•] DRAINMOD-NII and ADAPT performed equally well in predicting monthly subsurface drainage. [•] DRAINMOD-NII performed slightly better than ADAPT in predicting monthly nitrate losses and annual N budget. [•] DRAINMOD-NII prediction of denitrification rate was better than ADAPT prediction.
