In soil science, new methods and instruments are widely used to measure the physical properties of soils (granulometric composition), pore space in 3D images (tomography), contact angle of wetting, rheological characteristics, etc. These properties and parameters should find their application in modern soil research . The data on the relevant soil parameters obtained on the new equipment are analyzed, comparing them with traditional soil studies. New devices and methods require a lot of methodological work to establish and identify the limits of their applicability, optimal ranges, measurement conditions and, in general, standardize procedures for experimental determination. Such sections of soil physics as the study of the granulometric composition by sedimentometric and laser diffraction methods, the analysis of porous space by tomographic methods, the determination of the contact angle of wetting, and the use of the results of these methods in modern soil physics are considered
