الملخص EN

This study was conducted during the spring of 2023 with the aim of studying the extent to which agricultural soils are affected by salinity in Al-Zahra region, for this purpose, (13) soil samples were taken and distributed over the entire area and at a depth of (0-30cm) from the soil surface, preliminary treatments and then laboratory analyzes were conducted to estimate each of the saturated soil extract (ECe), soil (pH), and dissolved ions sodium, calcium, magnesium, and the sodium adsorption ratio (SAR) then the soil was classified according to the American classification of soils affected by salinity.

The results showed that some agricultural soils in the study area are affected by salinity, as the degrees of salinity ranged according to the American classification among soil types (Non Saline - None to slight) 54%, (Very slightly saline - None to slight) 15.3%, (Very slightly saline - Light to moderate) 7.7%, (slightly saline - None to slight) 15.3%, (Moderately Saline- Light to moderate)7.7%, The general percentage of soils affected by salinity was 46% of the total studied soils.
