Number of factors which create soil temperature and humidity feature are closely related to one another and in affect each other. Therefore, the spatial and time allocations are different. Studying soil moisture and temperature regime is significantly important for vegetation, grazing, agriculture and engineering construction. Objective of the study is to do preliminary estimation how changes in soil ground temperature relates to surface and air temperature and intend to use the results further research. We conducted research on soil temperature regime by using air temperature observation data and of 5-95 cm soil profile depth data since 2007 of Automatic weather station. They are temperature basic indicators of Davaat field station, average annual temperature, temperature amplitude, freezing and melting period of soil, soil and air temperature dependence.
