Abstract

              The current study aims to following up the changes which may take place in some morphological and pedogenic characteristics on three soil orders, Vertisols, Entisols and Aridisols in Qalubeya Governorate. Six soil profiles were selected to represent six soil groups. Twenty-nine profiles were examined, six out of them representing this study. (RHD) relative horizon distinctness 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 (PDI) values were calculated from horizon index values using quantitative profile index methods.                 The RHD values coincide with those of RPD ratings and Profile index values. Data revealed that the clear differentiation between the older soils (Typic Torrerts), the recent soil (Vertic Torriflavents, Typic Torrifluvents, Typic Torriorthents and Typic Torripsamments) and Aridisols (Typic Calciorthids). The study occurs that the soils of Typic Torrerts had developed more than the other soils of Entisols and Aridisols.
