Abstract:

This study was carried out to evaluate the variations and suitability of some soils located within the University of Ibadan for their current land uses. Six soil types were selected and profiled based on their current land use types which are paddock, forest, cassava, fallow land, maize/vegetable and oil palm plantation. The morphological properties of the soils were examined in standard soil profiles. Samples were collected from the surface (0-15 cm) and from each pedogenic horizon of the profiles for laboratory analysis. Suitability evaluation was carried out using land use requirements and factor rating for each of the land use types following parametric and non-parametric methods. The soils were classified at Series level as Olorunda (Typic Kanhaplustalf), Makun (Plinthic Haplustalf), Iwo (Typic Kandiustalf), Mamu (Plinthic Kandiustalf), Adio (Aquic Udifluvent) and Matako (Fluventic Haplustept). The evaluation methods used revealed that Olorunda and Mamu series currently used as paddock and fallow land, respectively, are highly suitable (S1) for cassava production while Makun and Iwo series currently used as forest and cassava, respectively, are moderately and marginally suitable (S3) for cassava production but highly suitable (S1) for maize production. However, Adio and Matako series currently used for maize cultivation are best suited as a forested area due to drainage problems. The common constraints to current land use types are soil fertility, climate, drainage and topography. This study revealed that current land use types are sometimes not the best suited in terms of land potentials which calls for proper land evaluation for any area that would be used for agricultural purposes in the future.
