It's adjacent to the southern part of Al-Najaf Sea and its area (17150.5 ha), located between the longitudes 425594E and 445138E and between the Latitudes 3521842N and 3538169N (UTM), it's covered the soil types and its geomorphological units which located within the sedimentary environment of Al-Najaf Sea. The semi details soil survey was carried out to selected area for study by grade soil system and according to soil texture examination results, ten heterogeneous sites were selected and geographically determined using a GPS device. In every study area, the pedon was digger and morphologically soil units soil units descripted. The samples were then taken from each diagnostic horizon and transferred to the laboratory for some chemical analysis and physical measurements. According to the results, the soil of the study areas was classified from the level of the order to level the family according to the American system (2014) and was completed to the level of the series based on the classification system of soil proposed by Al-Aqadi (1976 and 1982). The lands of the region were classified according to the productive capacity proposed by Klingebiel and Montgomery (1961). The results showed that there is a variation in the morphological characteristics, whether within the single pedon or the study area, due to the effect of the topographic factor, which was reflected in the characteristics and thickness of the horizons and the nature of their arrangement and the accompanying characteristics of each horizon. The pidogenical processes, mainly washing, loss and gain, salinization have been reflected in the presence of some subsurface diagnostic horizons like the calcic, gypsic and salic horizons, with the supremacy of the primordial evolution diagnostic surface horizon, represented by the Ochric horizon. The results of the texture class showed a difference in the soil content of the soil separators indicated that there was a difference in the soil content of the soil from the main soil separators, depending on the topographical location. The results of the cartographic analysis of the texture class map for the first meter indicated the dominance of moderately fine varieties (43.6%), while the coarse texture showed lowest percentage(5.3%). The studied soils was different with carbonate content and had a different distribution with depth due to the effect of situational conditions. The values of this component ranged from 145 to 500 gm.Kg-1 , the state of variation in the distribution pattern of this component in the study pedons is consistent with the state of variation in the calcification activity and the observed elevation of this

Morphological and some soil physical and chemical properties for represented pedons of every secondary physiographic unit within the projects above were studied. The land agro-ecological characteristics which directly affect the land suitability for Barley cultivation were circumscribed, which included Ecoclimatological characteristics, the evaluation of these characteristics was carried out by interconnection between parametric method and limitation method which was suggested by (20), according to the results the lands were classified according to their suitability for barely cultivation

The soils were classified according to the American classification for the year 2014 for the family level. So that we completed the classification to the level of the series according to the Al-Agidi proposal of 1976 and 1981 for sedimentary and developed soils respectively. To study the effect of the geomorphological site on soil characteristics in the topographical sequence.The results showed a significant effect of the geomorphological location on the morphological characteristics of the soil, ...
