dc.description.abstractrésumé:Notre travail s’est intéressé à la caractérisation pédologique d’une exploitation agricole irriguée d’une région aride cas de la STEP de SAID-OUTBA (Ouargla), qui se caractérise par une texture sableuse du sol avec des conductivités électriques plus au moins élevées, le maximum et le minimum sont de (4,80 ds/m à 1,9 ds/m). A partir des prélèvements des enchantillons dans les horizons de chaque profil les principaux résultats indiquent une supériorité remarquables des ions chlore et sulfate parmi les anions et le sodium parmi les cations. Cela se confirme par la présence majoritaire des sels neutres NaCl (Halite) et N 2 SO (thénardite). Ces mêmes sels sont caractérisés par une diminution en concentrations selon l’’augmentation de la profondeur. 4 Summary Our work has focused on the pédology characterization of an irrigated farm in an arid(dry) region , the case of STEP of SAID-OUTBA (Ouargla), it is characterized by sandy structure (texture) of sil with slightly high electric conductivity. The maximum is 4,80 ds/m and the minimum is 1,9 ds/m). From the samptes taking of each profil, the main results has showed a remarkable superiority of the anion chlorine and sulfate (sulphate) amang the anions and the sodium among action.That , what has been confirmed by the major presence of neutral solt NaCl (Halite) and N 2 SO (Thénardite) these salts are characterized by a decrease in concentration according to the increase of depth 4en_US
