دراسة بعض الخصائص المورفولوجية و الفيزيائية و الكيميائية لترب شط العرب شرقا و خور الزبير غربا في محافظة البصرة

Abstract EN

This study was conducted to find out some of the morphological, physical and chemical properties of soils in the physiographic units prevailing in Basra Governorate by adopting field and laboratory work and drawing maps using the GIS program for the study area located within the administrative borders of Basra Governorate for an area of 2091 km2 and a Landsat-Zone satellite mirror was used.

-39-2018 Five sites for soil resources were identified, depending on the variation in the saline index, and they were distributed over the study areas, namely Kot El-Zein, Seyhan, Dweib, Bahar and Maamer.

Soils were classified according to Soil survey staff 1999 as Typictorrifuvents with three series, namely MI12, MP12, DP12, according to Al-Akidi classification.

Clay particles predominate, followed by silt and sand in the soil of the study area.

The horizon A was characterized by a relatively high organic content compared to the subsurface horizons, as the organic content decreased Mmazad of the values of its bulk density.

It was observed that the carbonate content was high (335.23-102.13) g/kg-1 with a homogeneous condition with the depth.

The soil salinity condition of the slags ranged to very high in most of the study areas, reaching up to 140 decismens m-1.

Sodium and chloride ions were prevalent in the soils of the study area.

The dominance of the acute-angled mass structure, as it was found that there is a difference in the values of strength in its three states: dry, wet and wet.
