Soil Microscopy and MicromorphologyA comprehensive treatment of the subject with emphasis on thin section soil morphology. Coverage includes soil fabric, soil forming processes, microenvironments, mineralogy, weathering, root-soil/soil-organism interactions and structure deterioration. Every attempt has been made to use simple nomenclature and standard terms. Updated with the addition of TEM and SEM data. |
