Soil profile data taken over 5 yr period (1971-1975) at Vicosa were used to estimate the parameters for 2 types of solutions of the general heat conduction equation. The solutions in Fourier series expansion and sinoidal form were used to estimate the soil temperature at 5, 10, 20 and 30 cm depth using soil temperature data of 2 cm depth taken throughout 1976. The estimated temperatures were compared with measured 1976 soil temperatures. The soil temperatures computed from Fourier series expansion technique were more accurate than sinoidal solution of the heat conduction equation for every soil depth. The damping depth of the soil temperature depends on soil depth.
