EVALUATION OF SOME SOILS IN SOUTH-WESTERN NIGERIA FOR ARABLE CROP PRODUCTION

Five representative soil profiles were excavated and examined along a toposequence at different physiographic points in Itagunmodi area of South Western Nigeria. The soil series identified were Ibule, Ijare, Owena, Itagunmodi, and Adio. The soils were characterized with physical, chemical, and mineralogical analyses. Ibule series was not suitable for yam and cassava production. Ijare series was marginally suitable for yam, maize, lowland rice, and cassava production. Owena and Itagunmodi series were highly suitable for yam, maize, and cassava production. However, the latter two series were moderately suitable for lowland rice. Adio series was only suitable for lowland rice production.
