Abstract: After sowing of cultivated plants, there are many weed seeds spread in crumbled intermittent. At the beginning of vegetation weeds overcome cultivated plants and create competition. Their vitality can significantly been reduced by treating upper soil layer with wet water steam. The aim of the research is to determine the character of temperature field’s distribution and its intensity in the upper soil layer of intermitten. The experiments were carried out using (Calc (or) i-EpihypoglevicLuvisol, LVg-p-w -cc (sc), an ore-rich soil passed through a 17 mm sieve. The character of temperature field distribution and their intensity in the upper soil layer are fixed by 0.19 mm diameter nickel-chromolete copper-temperature sensors, placing them according to pre-prepared measuring schemes in the measuring planes. The changes of temperature field are registered with the Almem device. The results of the research showed that the character of the temperature fields distribution and its intensity in the upper soil layer depend not only on the type of soil, its density, moisture and the initial temperature, but also on the duration of the treatment using wet water steam, the amount of water steam supplied to the upper soil layer and the amount of overpressure. The results of the research carried out make it possible to add one more technology to the general technology of weed control using wet water steam - the thermal destruction of weed seeds in the upper soil layer
