Explain in detail about soil micromorphology

A good examination with optical aid reveals more detailed features which are helpful in understanding pedogenesis. This is known as  soil micromorphology.  This can be done by hand lens to some extent but rigorous examination needs preparation of a thin section of a selected ped. This ped is impregnated with resins which on drying becomes as hard as rock and can be cut to thin sections for examination under a petrographic microscope.  A good deal of information, viz. origin of parent material, exogenic processes, soil forming processes and land use management etc. are deciphered.
