Basis of the study was made up of the results of automatic, hourly measurements of air temperature and bare soil temperature originating from the agrometeorological station in Lipnik (53^o21’ N; 14^o58’ E, 30 m AMSL) from the period of 2001-2005. Basing on the results of the linear regression analysis, relationships for particular months were determined between daily soil temperature at four depths and air temperature set in seven different combinations. It was stated that the highest possibilities of daily soil temperature prediction in profile to 50 cm are characteristic for the air temperature that is the average from 24 hourly measurements. Average absolute differences between the actual soil temperature and the one calculated from equations for this relation oscillate in the particular months between 1.3^oC at the depth of 5 cm and 0.5^oC at the depth of 50 cm. On average, the smallest differences apply to the warm half of the year and the depth of 50 cm. It was shown that significantly smaller possibilities of the estimation of daily soil temperature values are characteristic for daily air temperature amplitude.
