Soil samples were taken at the Novaya Panika test site (Frolovsky district, Volgograd region). Dark chestnut soils are represented by varieties of dark loamy and medium loamy on loess-like loams, and light loamy on deluvial loams, represented by sandy deposits. The ratio of the coarse fraction to the fine fraction did not reveal sharp fluctuations in changes in the structure. Differences in indicators occur at such small levels (thousandths and tens of thousandths) that this only indicates an even greater detail of thermodynamic units. The general indicator of a variety of light loamy, medium loamy, heavy loamy dark chestnut soil, destruction associated with erosion, deflation, various types of anthropogenic influences or the synthesis of neoplasms, revealed an entropy indicator (Пs) and energy (ПG) (ПH) equal to 0,5 units. The results of the thermodynamic approach to assessing the intensity of soil formation considered in this work show the broad possibilities of thermodynamic methods. Using the approaches of different scientists in the article on the basis of our data on the granulometric composition and gross chemical composition to the energy of soils, taking into account the entropy and energy components, revealed the importance of the dispersion of matter in their energy intensity. The greatest potential of residual energy is present in the silty fraction of loam varieties of the subtype of dark chestnut soils.
