Abstract

Heat flow is shown to mainly be due to diffusion in soils. Diffusion is also called conduction and is the process by which solar radiation is propagated downward inside the soil profile. Fick’s equation for heat flow is described in terms of temperature gradients and thermal conductivities. Soil heat diffusivity is also used to explain temperature changes within the soil profile. The continuity equation is also used to quantify temperature changes in depth and time. A simplified but complete model for daily temperature changes in the soil profile is discussed in order to understand how the heat propagates in depth over time.
