The research was carried out in 2019 at the test fields of Krasnoyarsk Research Institute of Agriculture of the Federal Research Center Krasnoyarsk Science Center SB RAS located in the village of Minino, Yemelyanovsky District. Sensors were installed in spring wheat, spring barley and spring rapeseed to record soil temperature at different depths (0, 5, 15 cm). Temperature data were recorded hourly, at the beginning of each hour. Soil temperatures were recorded at different depths and registered for the main stages of plant development for different field crops. Studies have shown that the largest daily fluctuations in soil temperature occurred in the upper horizon for all the studied field crops. In 5 and 15 cm horizons soil temperature was less exposed to daily fluctuations. The dynamics of changes in soil temperature was monitored with the special focus on the stage of plant development. In the stage of seedlings, when the surface horizon of the soil is open, the greatest daily fluctuations were fixed; with the increase in biomass, the shading of the soil surface changed, while the soil temperature in the upper horizons decreased.
