Abstract: The soils of two toposequences in the sub-humid tropical climate of Southeastern Nigeria were characterized and assessed for yam (Dioscorea spp.), cassava (Manihot esculenta) and maize (Zea mays) production in this study. Data were obtained following standard field and laboratory analytical procedures. Six profile pits were dug three on each toposequence described and samples from the pedogenic horizons were collected, processed and analyzed. The profiles located at Ekpe village toposequence were designated EUP, EMP, ETP for upper- , Mid- and Toe- slopes respectively. The corresponding profiles at Amadia village toposequence were designated AUP, AMP and ATP. The soils were generally deep, loose, slightly sticky and non-plastic. The dominant textural was sandy loam or loamy sand. The soils were generally acidic (pH
