Abstract

The interaction of land use and time on some soil water transmission properties and fertility status of an Ultisol was examined. Results indicate that the texture of the soils ranged from sandy loamy to sandy clay loam and was unaffected by land use and time. The bulk density varied significantly across the land uses with the Sand mining site SM having the highest bulk density of 1.7 and 1.78 g/cm3 in the first and second years respectively. The Primary forest, PFL had the lowest BD of 1.50 and 1.78 g/cm3 in the first and second year of studies respectively. Similarly the percentage porosity varied significantly across the four land uses and has its highest value of 43.1 and 42.3% in the first PFL of the first and second year studies. Also the saturated hydraulic conductivity KSat and moisture content MC were significantly different across the four land uses, the Ksat was highest in the PFL in both first and second year of studies (17.2 and 14.7 cm/min), the least Ksat values of 6.70 and 5.88 cm/min occurred in the 1st year sand mining site SM. Similarly there was a significant difference (P>0.05) in the percentage organic matter OM, Total nitrogen N, available phosphorous P, exchangeable acidity, Percentage base saturation BS, and CEC across the land uses, however the total N was only significant in land uses PFL and not in the other land uses. Generally the soil quality indicators ranged from low to moderate in ratings and have affected productivity of recent in the area. Appropriate land uses that will restore the productive potentials of the soil should be adopted and sustained. Similarly the organic matter of the soils should be improved on as this will go a long way in improving appreciably the poor soil water transmission properties.

Keywords:
Land uses, organic matter, saturated hydraulic conductivity, water transmission properties, pH.
