Abstract

After sowing of cultivated plants, weed seeds is scattered in row spaces. Weed seeds is vegetate ahead of cultivateed plants and consist a competition to that plants. It`s possible to reduce weed in vegetation period if the top level of soil is treated with the wet water vapor. The purpose of research- estimate the formation of 100°C temperature field in the soil sur-face, by the adding the wet watter vapor. In this particular case, four types of soil is being studied. The study recorded the temperature of the soil at different depths and in different planes . Character of temperature fields distribution and its characteristic was measured with Almemo device. The results showed that the distribution of temperature fields depends on the duration of water vapor impact in the soil. Each case of soil studies have shown distinct results.
