Suitability evaluation of land for some commonly grown crops in Abeokuta, Ogun State: Challenges and limitations
Main Article Content
Abstract
A detailed soil survey was carried out at the Teaching and Research Farms of Federal University of Agriculture, Abeokuta to establish an information for land planers and farmers on the suitability of the land for some commonly grown crops in Abeokuta.. Following observed soil variation, modal profile pit was dug, described and sampled following standard guidelines. These samples were subjected to physical and chemical analyses. The result showed that the organic carbon, available phosphorus and the exchangeable bases were low across all the profiles while the total nitrogen was only moderate at the surface but low as the soil depth increased. The soils were suitable for maize and cashew using parametric and non-parametric approaches but permanently not suitable for oil palm using non-parametric approach as climatic condition being the limiting factor and marginally suitable using parametric approach.
