Abstract: This study was conducted on the soils of Babylon Governorate, where three sites were selected to represent different depositional environments of the Euphrates River, located within the districts of Al-Musayyib, Al-Hilla center, and Al-Kifl. Three sub-sites were chosen within each district at two depths (0-30 cm and 30-60 cm) to investigate how the distance from the sediment source affects soil properties, using conventional statistical analysis. The results showed a variation in soil texture, with clay content increasing as the distance from the depositional source increased, reflecting changes in the sedimentary environment. Chemically, the soil properties varied significantly between locations and depths. Electrical conductivity (EC) values ranged from 78.19 to 113.75 at the 0-30 cm depth and from 70.56 to 178.98 at 30-60 cm, with noticeable skewness and standard deviation. Soil pH values showed relatively slight variation but high coefficients of variation (CV), indicating sensitivity to site-specific conditions. The Exchangeable Sodium Percentage (ESP) values were highly variable, reflecting differences in sodium accumulation. The CaCO₃ and gypsum contents also varied widely across sites and depths, with high skewness and standard deviations, indicating heterogeneity in their distribution. These variations are attributed to differences in physiographic positions, groundwater levels, and soil management practices. The findings highlight the importance of analyzing morphological and chemical soil characteristics when planning for optimal agricultural land use in the Euphrates river environments.
