Effect of vegetation (palm trees)‎ on some of the physical and chemical properties for the ancient Babylon soil

الملخص EN

The current study included the selection of four regions of Babylon's archaeological soils located between two longitudes (32 ° 33 '0 ”-32 ° 33'55” north), and between two latitudes (44 ° 05' 03 '- 44 ° 25' 37 'east).

22 samples were taken at the surface depth of (0-30 cm) and the rhizosphere of (50-60 cm) in order to study some of the physical and chemical properties of Babylon's archaeological soils through palm trees with long age.

The volumetric distribution of the soil separates and its textures were varied at the two depths, even in one soil, and the dominance of the sand, silt and clay content alternated.

As for the soil interaction (pH) ranged between 6.

While the different magnesium forms were for soluble between (1.
