“…The mean values of the percentage sand, silt and clay across the various land uses for the first and second year studies are shown in Tables 1 and 1 .The bulk density values varied significantly across the four land uses p<0.05.The low bulk density in the PFL was premised on the improved organic matter content as bulk densities have been reported to vary inversely with the organic matter (Gupta, 2004) of soils. The increase in bulk density in the SM may be attributed to the loss of vegetative cover from the soil and large scale use of machinery which led to the loss of organic matter thereby resulting to high bulk density, Oguike et al [12] corroborated the above findings. Also the percentage total porosity varied significantly across the four land uses (P<0.05).…”

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.

“…22 m 3 m -3 . The higher volumetric moisture content recorded under forest and continuously cultivated land than in excavation site could have been caused by the presence of soil organisms which helped in producing high organic matter content which provided a larger surface area needed for the absorption and retention of water molecules (Oguike and Onwuka, 2018). The lower volumetric water content of soils under excavation site may be due to their higher capillary rise (as a result of the high clay content) which may have stimulated the evaporation of soil moisture (Nugraha et al, 2016).…”

Article InfoAn in-depth knowledge on variations in soil heat transfer under different land uses is essential for proper understanding of the variations in thermal energy transfer under different human activities and modifications on land. This paper presents an investigation on the variations in soil heat transfer under different land use types in Abia State. This study evaluates three land use types: forest land (FL), continuously cultivated land (CC) and excavation site (EX). The parameters investigated in this study include; particle size distribution, bulk density, volumetric moisture content, atmospheric temperature, soil temperature, soil thermal conductivity, soil heat flux, soil volumetric heat capacity and soil thermal diffusivity. The results show that the different land use types studied influenced the soil heat energy transfer and had a significant effect on soil thermal properties. The results revealed that excavation site recorded the highest soil bulk density (1.70 Mg m -3 ) and soil temperature (42.6 o C) while forest land recorded the lowest bulk density (1.36 Mg m -3 ) and soil temperature (30.3 o C). The transmission of heat through a unit length of soil per unit cross-sectional area (2.476 W mk -1 ) was higher in forest land than the other land use types studied. Soil under continuously cultivated land recorded the highest volumetric heat capacity (1.407 J (m 3 K) -1 ). This study will help farmers and land owners in terms of choice and management of different land use types for agricultural and industrial purposes.
