The 10-day period mean soil temperature at the depths of 2, 5, 10, 25, 50 and 120 cm and at 08.00, 14.00 and 20.00 hours, the direction of heat flux at these depths as well as the conditions favouring temperature induced water vapour flux within the soil profile were studied in a loamy Entisol. It was found, for any depth and at any hour studied, that the soil temperature fluctuated in accordance to theory and it can be presented by a simple two-term harmonic. It was also found that the direction of heat flux was dependent on the soil depth, the season of the year as well as the hour of the day. The temperature induced water vapour flux was found to depend on both the hour of the day and the season of the year.
