The partitioning of mobile fractions of chemical elements in the mineral loamy soils during natural regeneration after plowing in Western Russia.

Natural regeneration of forest soils affected by agricultural practices is a common phenomenon in many regions worldwide, particularly in boreal ecosystems. Affecting soil quality, the partitioning of extractable fractions of heavy metals and metalloids (HMMs) is not studied during natural regeneration. The following stages of natural regeneration after plowing have been identified in the Smolenskoye Poozerye National Park: agrocenosis, meadows, forests with the age of the tree stand <30, 35-60, 70-80, 80-110, 90-130, 110-135 years.

Data on the soil and vegetation properties at the small gully catchment area: Steppe region of Kalmykia Republic (South Russia).

In rural areas, research on the environment in native (untaught) soils is important to understand the rate of pedogenesis and to prevent the problems associated with hidden huger. In this article, original data on vegetation, chemical properties and elemental and mineralogical composition of Kastanozems (Protosalic, Siltic) and Hypersalic Solonetz (Siltic) of the small gully catchment (2 ha in total) located at the NE Ergeni Upland (Western Kalmykia, Russia) were presented. Vegetation was described and cut off (to characterize an aboveground biomass) at 13 key plots of 1 × 1 m.
