Abstract

Six pedons occurring in Cuddapah basin were studied by scanning electron microscopy (SEA/). The two important pedogenic processes, namely, pedoturbation and clay illuviation in Vertic Ustochrept have resulted in omnisepic plasmic fabric. The surface morphology of oxides and hydrous oxides exhibits glaebular nature in Typic Ustochrept. The illuviated oriented clay in textural B horizon of Typic Hapludalf has resulted in lattisepic plasmic fabric. The pedogenic continuity of Typic Chromustert A-C profile is established by the repetition of rhombohedral frame work (fabric) from the C horizon of limestone parent material to the ped faces of A12 horizon. The presence of rubified lithorelict in endopendon of Typic Eutrochrept has qualified it for an Inceptisol in spite of substantial increase in clay content
