The effects of different levels and methods of nitrogen fertilization and of different irrigation levels on soil nitrogen dynamics and on potato crop yield were studied. On the basis of a two year experimentation, nitrogen fertilization didn’t show any positive effect on tuber yield, as a result of the already high nitrogen availability of the investigated soil; on the other hand, high amounts of nitrogen fertilizer significantly contributed to encrease NO3-N concentration within the lower soil layers.

Abstract
The effects of different levels and methods of nitrogen fertilization and of different irrigation levels on soil nitrogen dynamics and on potato crop yield were studied. On the basis of a two year experimentation, nitrogen fertilization didn’t show any positive effect on tuber yield, as a result of the already high nitrogen availability of the investigated soil; on the other hand, high amounts of nitrogen fertilizer significantly contributed to encrease NO3-N concentration within the lower soil layers.
