“…In the forest steppe zone of European Russia, such studies have been performed for many years. Their results can be found in [13,21,22]. As for the north east of the Great Plains, the authors do not have this information.…”

“…The study performed by Sauer et al [32] showed that the intensity of the organic carbon sequestration in the topsoil (0-30 cm) under the artificial forest plantations increases in the first 30 years of growth of the trees and then decreases to zero values under 50 year old trees. It is also known that the advancement of forests over steppe cher nozems in the Late Holocene was accompanied by the transformation of chernozems into gray forest soils with lower reserves of organic matter [2,20]. In 1930, the study of Tumin in the Kamennaya steppe showed that the accumulation of organic matter takes place under recently planted shelterbelts [16].…”

“…The 14 С-dates of humus in each of the investigated layers (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40), and 50-60 cm) increase with an increase in the duration of the soil plowing, which is quite reasonable, because the agrogenic dehumification of the soils proceeds mainly at the expense of the labile (and young) humus. This is true not only for the upper but also for the deeper horizons.…”

Abstract⎯Agrochronosequences of chernozems with different periods of their use in rainfed farming with application of traditional technologies have been studied in a typical forest-steppe area in Belgorod oblast. Certain stages in the development of these soils during more than two centuries of their agricultural use have been identified. These stages are related to changes in the intensity and direction of soil forming processes, such as soil compaction, soil aggregation, dehumification of the upper horizons, calcification of the soil profiles, argillization, etc. A significant impact on the soil changes during the agrogenic evolution of chernozems is exerted by the digging activity of burrowers, which is especially pronounced in the old-arable chernozems.Keywords: chernozems, soil agrochronosequences, tillage, forest-steppe, stadial specificity of the agrogenic evolution, multiple study methods DOI: 10.1134/S1064229317050040 Kozlovskii [17], and many other scientists. These studies allowed us to gain a better understanding of the essence of soil forming processes in plowed chernozems and their changes with time and to develop a set of methods aimed at conservation and reproduction of these soils as the most valuable nature resource of Russia. However, the diversity of the existing information on transformation of chernozems under the impact of tillage poses new problems related to the genesis of the new soil properties and processes in plowed chernozems. The changes in the morphogenetic character of plowed chernozems and in the intensity of a number of soil processes (in particular, dehumification) in them should be specially analyzed. It should be noted that, in some studies, the most important problem of the loss of organic matter from chernozems under the impact of tillage is considered not quite correctly: only the content of humus in the plow horizons is analyzed, whereas changes in the bulk density of the soils are ignored.

“…The increase in the anthropogenic load on soils (including gray forest soils) can provoke their agro chemical degradation: an increase in the acidity of the plow layer, changes in the composition of the exchangeable cations and degree of base saturation, and dehumification. The rate and evolution of the degradation directly depend on the degree and dura tion of the anthropogenic impact [9,19,22].…”

Abstract-The changes in the properties of dark gray forest soil in the Ukrainian Western Forest Steppe under the effect of long term agricultural use in a grain-row crop rotation without fertilization and with the application of mineral and organomineral complex fertilizers have been studied. The changes in the morpho logical properties of the soil, the reaction of the soil solution, the total and exchangeable acidities, the total exchangeable bases, the degree of base saturation, and the content and reserve of organic carbon over a 50 year long period of plowing have been studied using different methods. It has been found that the acidi fication of the upper layer was intensified and the content of organic matter and the degree of base saturation decreased during the period studied . The effect of the management practice on the evolution and dynamics of the soil degradation has been studied. It has been shown that the cultivation of soils without fertilization primarily resulted in a decrease in the humus content; the application of mineral fertilizers increased the acidity of the soils.
