The study of residual effect of N fertilizer on the soil is important research so far so good.This study was conducted on Brack-Ashkda agricultural project soil middle south of Libya to investigate the effects of soil depth(0-180 cm) and duration of soil use (January, April, July and October) on the presence of the level of total N as a residual effect of additions of N fertilizer to the soil.Results showed that the total N concentrations decreased with increasing soil depth(0-180 cm) and there are significant differences between them in all studied wells.Also, the results showed that the concentrations decreased with increasing duration of soil use from January until October. There are significant differences between the total N concentrations along the duration of soil use in all studied wells.
