WebSoil temperature is intimately linked to soil water and pore space. Water has a greater specific heat (i.e., the energy required to heat a mass by 1°C) than soil minerals (e.g., … WebIn this study, we demonstrate that the heat-pulse method can give accurate theta estimation when values for the specific heat of the soil solids (c(s)) are determined using the heat-pulse method. Heat-pulse measurements were performed on packed columns of three soils with a wide range of bulk density (rho(b)) and theta.
