The mean annual soil temperature, evaluated for the depths 5, 10, 20, 50 and 100 cm is negative and varies between -4.5°C in the subsurface layer and -4.2°C in the deeper parts of the analyzed profile. The soil is frozen through almost nine months in the year. During the lasting a short period spring and autumn there is an isothermy in the soil. Greater variability occurs in the subsurface layer. The layer between 50 and 100 cm accumulates the greatest amount of the heat. During the spring and the first half of summer the upper layer accumulates more heat. The soil temperature depends significantly on the variability of the air temperature. Additionally the soil temperature is influenced also by sunshine duration and snowcover depth. The annual variability of the soil temperature can be approximated with the first harmonic. Below the depth of 185 cm, the inter-annual soil temperature oscillations do not exceed 0°C. There are positive tendencies in variability of mean soil temperature time series at all depths. At the depth of 10 cm this tendency has a character of a statistical trend. Its value is +0.126°C/year in the period 1979-1999.
