Effect of Land Use on Soil Degradation and Soil Productivity Decline on Alfisols and Ultisols in Ogun State in South Western, Nigeria
One of the critical factors influencing land degradation is land use. However, the extent to which land use influences land degradation has not been fully ascertained in the southwestern part of Nigeria (i.e. particularly in Ogun State). Thus, this study was designed to assess the extent to which land use influences crop productivity in Ogun State. Two major soil types identified at the site were Alfisols and Ultisols. Within these, three land use types (LUT) were identified: arable crop - Land Use 1, cash crop production - Land Use 2, and non-agricultural use – Land Use 3.
