EVALUATION STUDIES ON SOILS OF SOME DESERT AREAS DESIGNATED FOR AGRICULTURAL EXPANSION

Abstract
This study is aimed at evaluating some desert areas in the southern part of the New Valley (of the Egyptian western desert). The studied area is bounded by longitudes 29° 30' and
30° 30' East and latitudes 22° 30' and 23° 30' North. There were by six physiographic units (pediplain of sandstone, pediplain of claystone, alluvial deposits derived from sandstone, alluvil deposits derived from claystone, Aeolian plain, playa).
Twenty one soil profiles were chosen to represent the different physiographic units, and were morphologically described; their properties were evaluated. The results could be summarized in the following:
1. Morphological characteristics of the studied area:
The soils are characterized by four groups of relief: (1) almost flat: soils of pediplain of claystone, alluvial deposits derived from claystone, alluvial deposits derived from sandstone and playa. (2) very gently undulating to gently undulating: soils of pediplain of sandstone and alluvial deposits derived from sandstone. (3) undulating to gently undulating: soils of aeolian plain. (4) undulating: soils of pediplain of sandstone.
The three physiographic units, pediplain of claystone, alluvial deposits derived from claystone and playa are generally characterized by moderately to fine texture (sandy loam to clayey), other units are characterized by coarse texture classes (sandy to sandy loam).
