Soil temperatures predicted with the use of temperature gradient method (GRA-GRO model) were compared with those measured at the experimental site. The experimental data are close to the theoretical values.Unfortunatelythe some differences exist. The lack of agreement between the simulated and measured data is sometimes disappointing (end of simulation), but indicates more that anything else the areas in which our knowledge is lacking.Present results indicates that the model can be used for predicting the change of temperature of soil but the further studies in both the field and model verification need to pay respect to infiltration of water into soil after rain and measuring of thermal conductivity of soil.
