Abstract:
The differences in the qualitative composition of organic matter in the soils of natural and anthropogenically transformed landscapes in the south of Primorye were established by the method of chemodestructive fractionation (CDF). The lowest indices of the easily oxidizable part (EOP) in the organic matter are typical for soils of technogenic landscapes (embryozems) with very low humus content due to low reserves of aboveground phytomass and the supply of fresh organic matter of plant origin. Embryozems are characterized by a low supply of humus with nitrogen. Higher EOP values are characteris

Abstract:
Buried Late Holocene paleosols of the Nienshants historical monument at the junction of the Neva and Okhta rivers (St. Petersburg) have been studied. These soils developed from estuary deposits of the Littorina basin with abundant artifacts of the Neolithic and Early Iron ages (7–2 ka BP). The soil cover of the area consists of the mature dark-humus profile-gleyed soils on elevated elements of the mesotopography (3.0–3.5 a.s.l.) and dark-humus gley soils in the local depressions (2.0–2.6 m a.s.l.). The soils are characterized by the low to moderate content of humus of the ful

The dark-humus soil type was included in the updated legend of the Soil Map of the Russian Federation at scale 1 : 2.5 M, converted to the system of Soil Classification of Russia. The soil profile starts with the dark-humus horizon gradually merging to the parent rock; any mid-profile diagnostic horizons are absent. Large areas of dark-humus soils are found in the forest-steppe, steppe and taiga zones of the European Russia, Western and Central Siberia, in the Trans-Baikal region, the Altai-Sayany Mountains, and the Caucasus.

Abstract New data on the soils of mountain floodplains in the tectonic joints zone of the Mongol-Okhotsk Orogenic Belt on the example of the Upper Kerulen Basin are presented. Soil diversity is mostly determined by sedimentation conditions and drainage of the parent rocks. There are alluvial–humus (Fluvisol (Humic)), mucky–humus (Folic Fluvisol), dark–humus (Fluvisol (Mollic)), dark–humus gley (Gleyic Fluvisol) and dark–humus saline soils (Sodic Gleyic Fluvisol (Mollic)) were diagnosed.

Abstract Soils formed in treatment facilities of sugar beet factories in the forest-steppe zone of Kursk oblast were studied. Technogenic factors of soil formation associated with the industrial sugar beet activity and post-technogenic processes during the abandonment of treatment facilities are considered. The alternation of settling ponds and the earth walls separating them are the main factors determining “cellular” pattern of the soil cover. The mode of inflow and discharge and the composition of wastewater, as well as the duration of the abandonment of settling ponds determine the specifi
