The aim of the study was to investigate and evaluate the occurrence of salinity in two soil profiles in irrigated soils of a 30 years long Brack -Ashkada agriculture project and classify their degree of salinity. The study was carried on in well No. 6 which covers twelve farms. Soil pH, Electrical Conductivity (EC) and Exchangeable Sodium Percent (ESP) were measured at 25C; pH of soil samples ranged between 7.01 -8.00; Electrical Conductivity (EC) is between 0.513 -3.540 ds.m -1 ; and the

The pH of the soils that had been influenced by salinity farms 8 and 9 is 7. for the second and first soil depths respectively. According to the American classification of soil salinity, five sites which represent 8.3% of the studied sites were found either salted or effected by salt.
