Abstract : A method and a diagram of the instrument for measuring the surface soil temperature by its radiation is presented in this article. The method proposed makes it possible to measure surface soil temperature within an accuracy of 0.1 degrees. The most accurate method for the solution of this problem consists of the application of a non-contact method, based on measuring the surface soil temperature by its radiative emission. The application of a zero-radiation method for measuring the surface temperature is a way out of this situation; whereupon, by means of artificially controlling the temperature of the instrument the radiation balance is established between the radiation receiver (a black disc) and the surface under investigation. In this case the radiant heat exchange between the surface and the instrument is absent and the sources of errors mentioned may be eliminated. (Author)
