Abstract : In view of the lack of instruments for making direct measurements of the vertical heat fluxes in the upper layers of soil, this important component of the heat balance at the present time is determined solely by calculation. Various checks and comparisons have shown that the calculation method worked out by G.KH. TSeitin, based on a subsequent modification of D. L. Laikhtman's theory, is the most accurate. As N.P. Rusin has pointed out, this method leads to the following working formula for determining the values of the vertical heat flux on the basis of station observations of soil temperatures at the surface, and at the standard depths of 5,10,15, and 20 cm., in the upper layers of the soil.
