One major challenge of intensive crop production practice in riverine arears is low crop yield
due to chemically infertile soils, attributed to poor soil fertility management. This study
provides information on fertility status and morphology of floodplain soils using Onumirikwa
Ulakwo River, Owerri, Nigeria. In three geomorphic units:(i) crest (ii) terrace and (iii) back-
swamp soil was sampled from horizons of three profile pits and analyzed for physico-
chemical and morphological properties. Systemic soil categorization was carried out …
