Abstract
Variations in soil temperature with time were observed for Lipa clayloam soil with different moisture content levels. The experimental set-up consisted of a constant heat source directly on top of the soil column. Temperature readings at 0 cm, 3 cm and 6 cm from the surface of the soil were recorded. Soil samples with more water took longer time to reach saturation. Saturation temperatures were seen to decrease with depth and soil moisture content. The thermal conductivity of the soil samples was determined using Fourier's Heat Flow Law. Results (0.12 to 0.14 W/m K) were close to the published range for clay loam soils (Ghuman and Lal, 1985). Thermal conductivity was observed to be inversely proportional to the soil moisture content. Soil thermal heat flux was also obtained for the different moisture treatments. The amount of heat required to raise the temperature of the soil was found to increase with increasing moisture content.
