There are presents a developed method for predicting temperature of soil surface for next 24 hours with using data of air temperatures at height of 2 meters. The proposed method is a modification of the Mikhalevsky method, recognized in agrometeorology when predicting radiation freezes. Only dry-bulb thermometer temperature data and relative air humidity are available for application in automated systems. We have therefore obtained formulas for the calculation of dry thermometer temperature. A separate study was to test the simplified formula for calculating saturated vapour pressure above water in the temperature range 0-60 °C. The study showed the complete correspondence of the saturated vapour pressure above water value calculated by different methods in the range 0-60°C. The relative error in the given temperature range is not exceed 0.35%. Thanks to obtained equations, the value of dry-bulb thermometer temperature for the first decade of May 2020 was calculated. The temperature and humidity of the air were measured by the automatic station every hour, and the value dry-bulb thermometer temperature were obtained from psychrometric tables. The absolute error in the calculation of value drybulb thermometer according to the proposed formulas do not exceed 1°C in the temperature range 0-16°C.
