Abstract: ABSTRACT :
This study aims to use satellite images and Geographical
information system (GIS) for digital soil mapping and capability
assessment of the soil in the western side of El- Miniya Governorate,
Western Desert. To fulfull this objective landsat ETM image and
digital elevation model (DEM) of the studied area were used to define
the physiographic of the studied area. Fourteen soil profiles were
selected to represent the main physiographic units, the morphological
description was carried out and 50 disturbed soil samples were
collected for physical and chemical analysis. The correlation between
landforms and soils were carried out then the soil maps were compiled
using the Arc- GIS 9.3 software. The results indicate that the studied
area include eight physiographic, i.e, alluvial fan (6.29%), sand dunes
(10.94%), young terraces (2.5%), Old terraces (4.83%), Bajada plain
(13.57%), Wadi bottom (0.79%), rock land (39.76%) and longated
sand dunes (21.36%).
Using US taxonomy bases (2010), the studied soils could be
classified and mapped into four taxonomic units, Typic Haplocalcids,
Calcic Haplosalids, Gypsic Haplosalids and Calcic Haplogypsids sub
great groups.
According to land evaluation system undertaken by Sys and
Verheye (1991), the studied soils are affected by many of limiting
factors, i.e, soil texture, CaCO3 content and salinity and alkalinity
with variable intensity degrees. Also, the current suitability of the
studied soils assessed two classes of marginally suitable soils

(S3, Wadi bottom and alluvial fan) and unsuitable soils (N1, old and
young terraces, Wadi bottom, alluvial fan and Bajada plain). By
executing suitable soil improvement practices, the potential suitability
classes assessed two classes i.e, moderately suitable soils (S2) with
total area about 81188.5 feddans and marginally suitable (S3) with
total area a about 109846 feddans
