Shein E.V., Pochatkova T.N., Holodkov A.I. THE RHEOLOGICAL PROPERTIES OF SOD-PODZOLIC SOILFormation, stability and, on the other hand, the degradation of soil aggregate structure are the processes related to fundamental physical and chemical properties of the solid phase soil surface and are their functional manifestations. Rheological investigations allow to reveal the inner nature of the strength properties and provide an integrated assessment of the strength of the bonds involved in the formation of soil structure. In modern conditions of intensive anthropogenic load all the soil are exposed to a greater or lesser susceptible physical and technological degradation, which is manifested at different levels of structural organization. The purpose of the study — by modern methods of soil rheology set especially rheological behavior of genetic horizons of cultivated sod-podzolic soil under shear loads. The physical and chemical properties of the genetic horizons of cultivated sod-podzolic soils significantly affect the rheological behavior of the soil. Rheological properties were determined using a rotary viscometer "Reotest 2" with a cylindrical measuring device. The strength of the soil structure parameters, such as the commencement of the pressure of the soil suspension and the beginning of the destruction of the structure in the cultivated horizon is 20–40 kPa, then reduced in eluvial and increases in the illuvial horizon of up to 70 kPa. The viscosity of the start and end of movement in arable soil suspension horizons vary in the range of 110–120 Pa*s, and in horizons samples A-ELB-B and A-EL — in the range of 140–170 and 6–80 Pa*s, respectively. When shear deformations of soil horizons of sod-podzolic soil is predominant phenomenon rheopexy, with different participation tiхotrophic processes.Key words: soil, rheology, shear stress, strain rate, viscosity, strength, rheopexy.
