Abstract
Results of the 60-year research on soil physical properties at the large lysimeters of the Experimental Soil Station of Moscow State University are discussed. The main studied issues include the elements of soil water balance, soil evolution, soil temperature regime, and transport of various substances within the soil profile. The long-term changes in soil texture, soil mineralogy, and organic carbon content have been observed. The horizon sequence in the soil profile affects the intensity of drainage flux and its stabilization in the long-term aspect. The amount of the transit transfer of substances in different soil profiles depends on both profile structure and upper boundary conditions.
