Résumé
The current study was inspired by certain circumstances and hiata in our knowledge of the soils of Egypt, the understanding of the soil genesis and development is imperative in the other aspect of soil technology and utilization. Due to the nature of deposition of the alluvial parent material on the soils of the Nile valley, soil profiles show no morphological distinction existed in most regions of the valley and delta, the differentiation of the soils in to geomorphological groups and associations should be based on mineralogical, Pedographical, and Pedogenetical criteria. The completion of the high dam and the change in the prevailing system of irrigation from basin to perennial threatened to change the nature and compostion of the alluvial soils of Egypt, as well as, the hydromorphologic section of The Nile stream itself below the dam. The area studied covered most of the soils of minia governorate in middle Egypt. Due to the unaccessability of the aerial-photo pairs of this area, topographic maps and Field exploration were utilized the geomorphologic divisions recognized were : west Escarpment, desert playas, bluffs, western interference zone, western intermediate zone. Alluvial, western levee, Nile islands, eastern levee, mouths of the gullies, and Eastern escarpment. Each with its peculiar soil four east-west soil traverses at der-moas, Abo-korkas, samalut, and maghagha were planned twenty six soil brofiles were chosen, and ninty eight samples were collected.
