| Abstract | ||
| The current study aims to following up the changes which may take place in some morphological and pedogenic characteristics on two soil orders, Entisols and Aridisols in East lsmailiya area in Sinai. Eight soil profiles were selected to represent seven soil mapping units. Twenty seven profiles were examined, eight out of them representing this study. (RHO), the determination was made by a comparison of adjacent horizons the second rating scale (RPD) was made by a comparison of the last horizon, to the above horizons in the same profile. Some chemical properties such as salts, pH, calcium carbonate and gypsum were applied to calculate the points of pedogenic factors. Also Profile Development Index (POI) values were calculated from horizon index values by using quantitative profile index methods. The (RHO) values coincide with those of (RPD) ratings and profile index values. Data revealed that the clear differentiation between the recent soils (Typic Haplogypsids, Typic Haplosalids, Leptic Haplogypsids and Typic Aquisalids), the recent soil (Typic Torripsamments and Typic Torriorthents). The study accurse that the soils of Aridisols had developed more than the others soils of Entisols. | ||
