  • Geochemical characteristics of agricultural soils, Assiut governorate, Egypt

  • The Nile Valley soils are very comparable in composition and composed mainly of SiO2, Al2O3, Fe2O3, CaO, MgO, and TiO2 which represent about 88% of its chemical composition. The chemical composition gave an indication about the mineralogical assemblage of soil; quartz, clay minerals, and calcite. The results pointed to the mixed source (geogenic and anthropogenic) of Fe, Co, Cu, Ni, Zn, Zr, and Cr and the anthropogenic source of As, Pb, and Cd (especially phosphatic fertilizers) in the studied soil.

  • Mineralogical and petrographical studies of agricultural soil, Assiut Governorate, Egypt

    • Authors: El-Anwar, E.A.A.;  Advisor: -;  Participants: Mekky, H.S.; Salman, S.A.; Elnazer,, A.A.; Wahab, W.A.; Asmoay, A.S. (2019)

  • The studied soil is characterized by alkaline nature, low organic matter, and high CaCO3%. Mineralogically, the studied agricultural soil samples consist mainly of quartz, plagioclase, and minor calcite (as non-clay minerals), as well as montmorillonite, vermiculite, and illite in decreasing abundance order as clay minerals. The plagioclase consists of two minerals; calcined albite and anorthite.
