Abstract :Inappropriate land-use is a worldwide problem that negatively affects sustainable agriculture; hence this study, to recommend the preferred farming method. The study was carried out to determine the effect of different land-use system in Yenagoa and Southern Ijaw Local Government Area of Bayelsa state on selected soil physicochemical properties. The study took into account four land-use regimes, including virgin land insert ignore into journalissuearticles values(VVL, plantain plantations, fallow land, and plantain plantations insert ignore into journalissuearticles values(VVL);. The result showed that the different land-use type had significant effect insert ignore into journalissuearticles values(P< 0.05); on some physiochemical properties. Loamy sand dominated the Plantain plantation, sandy loam dominated the oil palm plantation; sandy clay loam dominated the virgin land while sandy loam dominated the fallow land. The virgin land showed higher mean values compared to fallow land oil palm and plantain plantation; the trend is as follows Base saturation: insert ignore into journalissuearticles values(VVL-42.35% > OPT-31.73% > FFL-29.12 > PPT-23.67%);, organic carbon/organic matter insert ignore into journalissuearticles values(VVL-21.67/43.33gcm-3> OPT-17.33/34.67gcm-3> FFL-11.67/23.33gcm-3> PPT-7.33/14.67g/cm-3);, CEC insert ignore into journalissuearticles values(VVL–1.83 cMolkg-1> OPP-1.10 cMolkg-1> FFL – 0.87 cMolkg-1> 0.66 cMolkg-1);, and exchangeable acidity.Land-use had a significant effect on bulk density and Porosity. The fallow land insert ignore into journalissuearticles values(FFL); showed less compaction with the lowest bulk density of 1.25gcm-3< OPT insert ignore into journalissuearticles values(1.34gcm-3);< insert ignore into journalissuearticles values(VVL); insert ignore into journalissuearticles values(1.30gcm-3);< PPT insert ignore into journalissuearticles values(1.34gcm-3);. It is therefore recommended that conservative measures such as land fallowing be practiced to regenerate lost and depleted nutrients in the soil; and also, for reduced conversion of forested lands to cultivated land.
