Abstract
In this study, the effect of soil surface temperature and meteorological characteristics parameters on the soil
electrical resistivity was investigated ; A multiple linear regression was applied to five parameters, which soil
surface temperature , wind speed, ambient temperature, solar radiation energy and air relative humidity. The
results were found that the soil electrical resistivity was effected on solar radiation energy s E , air relative
humidity RH , ambient temperature a T , soil surface temperature s T and wind speed s W , respectively.
Therefore the multiple regression equation was correlated
