الملخص EN

The study examined the physical characteristics of the soil of Al- Haidariyah area of Najaf Governorate by analyzing 32 soil samples depth (0- 30) and (31-60)cm .

The study included three types of soil: River shoulders , the soil of Rivers Basin and the soil of the plateau.

The soil tissue varied spatially at depth (31-60 cm).

The morphological description of cultivated and uncultivated soil showed that the degree of clarity of the building was moderate to the two depth , while the type of building size was medium for the deep.

permeability varies spatially in the rates of water permeability, as it was at the sites of the ponds lower: because of the relative decrease in sand separators and the high proportion of clay and clay separations, while the height of the rate in the shoulder soil by 1.1 cm / hr to the high percentage of sand separators and the decrease of the proportion of clay and clay separations either in the soil (overlapping) and raised the plateau, we find a significant increase when compared with the soil basin and shoulders It was also found that the color of the soil brownish yellowish and dark yellowish brown color Is predominant in most soil samples of the study area
