This study aims to estimate and evaluate the changes of some soils of EI-
Kharga Oasis using the morphology rating scale introduced by Bilzi and Clolkcez
(1977). Twelve profiles were examined, seven out of them representing this study. Soil distinctness and development were assessed using the yecent methods;
Relative Horizon Distinctness (RHO) and Relative Profile Development (RPD). Also,
profile index values were calculated from horizon index values using quantitative
profile index methods. The average RHO ratings of the studied profiles are 3 to 10, 7to 20, 11 to 12,
19, 9 to 11 and 3 to 5 whereas those ofRPD ratings are 9 to 14,17 to 19, 9 to 15,19,
12 to 16 and 3 t07 for the vertic Toniorthents, Typic Toniorthents and Typic
Tonipsamments, respectively. The RHO values coincide with those of RPD ratings
profile index values. Data revealed that the clear differentiation in the recent soil (vertic
Torriorthenls), (Typic Torriorthents) and (Typic Torripsammenls). The study occurs that the soils of vertic Toniorthents and Typic Torriorthents
have developed more than the others soils of Typic Tronipsamments.
