Owing to the fact that soil temperature is only measured at synoptic stations, reconstruction of this variable in other places is of great importance for many relevant agricultural surveys. Using 10-year (1996-2005) daily meteorological observations, including: air temperature, global solar radiation, precipitation, relative humidity, vapor pressure, wind speed and air pressure data, different empirical relationships are suggested. At statistically significant level (P0.85 for humid climates). Other results highlighted that the correlation coefficients decreased as the soil depth increased. The behavior of statistical validation criteria of the suggested relations are also discussed for all the mentioned climates. }, URL = {http://jstnar.iut.ac.ir/article-1-1229-en.html}, eprint = {http://jstnar.iut.ac.ir/article-1-1229-en.pdf}, journal = {Journal of Water and Soil Science}, doi = {}, year = {2010} }
