Abstract
A detailed survey of the soils of a toposequence at Odeda, Ogun State was conducted to characterize, classify and assess the suitability of the soils for sustainable production of rice. The rigid grid method of survey was adopted for soil mapping while the linear parametric and square root models were used for assessing the suitability of the land for rice production. The result of the study showed that the soils of the three pedons were loamy sand to sandy clay loam texture, fine to coarse sub-angular blocky structure and loose to hard consistency. All the pedons had redoximorphic properties with varying quantities of iron-manganese concretion in the sub soils. Soil reaction ranged from strongly acid to neutral (pH of 5.3 – 6.8) with low organic carbon (
