| Abstract | ||
| The current investigation was carried out to study the micromorphological features of some soils of Egypt represent the main soil orders, Aridisols, Entisols and vertisols. Undisturbed soil samples were collected from seven soil profiles to prepare thin section using standard techniques and examined by polarized microscope. The obtained results can be summarized in the folloing; the aridisols Typic Haplosalids are characterized by salic horizon, presence of halite crystals in some Vughs Voids and argillasepic plasmic Fabric was found in the lower layers. Entisols, Typic Torripsamment are characterized by single grains of sandy materials, simple packing Voids and the plasmic Fabric is sillasepic. The skeleton grains consist mainly of quartz grains with different shapes of angular and sub angular roundness and usually distributed randomly with feldspars and some opaque minerals.Vertisols, Typic Torrerts are characterized by argillasepic plasmic Fabric Voids are generally decreasing in size with depth and vughs and channels are the dominated Typic.Pedological features observed are residual partially decomposed plant Tissues with humified organic materials in black and brown colors especially in the surface layers. Lime and ferric nodules are found in the subsurface layers. The related descriptions pattern is porophyrosklic. | ||
