Soil heat flux plates were calibrated in the laboratory in steady‐state conditions and checked in the field vs. the soil temperature gradient thermal conductivity measurements of heat flux density. Good agreement was obtained after correcting for the flux divergence in the layer of soil where the temperature gradient was measured. Soil heat flux density measurements in a bare soil indicated that the heat storage in a 5‐cm layer of soil above the flux plates contributes significantly to the diurnal soil heat flux wave.
