This book explains the soils of the Delbo Wegene watershed which was characterized along toposequence to determine the physical and chemical characteristics, the mineral compositions, and to elucidate the soil genetic process and classify the soils according to Soil Taxonomy and World Reference Base (WRB) classification systems. Four pedons along toposequences were described and studied for their physical, chemical and mineralogical characteristics. Rock samples beneath the soil profiles were also collected for mineralogical studies. Delbo Wegene watershed is located between 06o52" 45.9" and 06o53"34.8" N latitude and between 37o 48" 10.5" and 37o 48"42.4"E longitude, with altitude ranging from 2100 to 2300 masl, in Wolayita Zone of Southern Nations and Nationalities and Peoples Regional State (SNNPRS) of Ethiopia.This book will be useful for soil scientists who are engaged in soil characterization and classification.
