Sandy soils of desert-like landscapes (tukulans) of Central Yakutia

Description
Summary:The soils of tulukans widely distributed in Central Yakutia were studied and presented. The parent materials for large areas of region are ancient alluvial sandy sediments of pre-Quaternary age. In Holocene, boreal coniferous taiga began to colonize these materials, but large areas remained without vegetation and were occupied by a large mass of sands. Under the influence of wind activity, ancient tukulans slowly advanced into the forest area. But under the conditions of the natural (climate dynamics) and anthropogenic impacts (forest fires, forest cutting and industrial development), a noticeable expansion of treeless spaces occurs and formation of young massifs of drift sands is observed. At the same time, there is a burial of the natural soil cover, and eolian soil degradation. Epialbic Arenosols are described in the studied area under dead pine forests. The Epialbic Arenosols (Aeolic, Areninovic) are formed within the actively developing part of tukulans without vegetation under homogeneous sand. The Protic Arenosols (Ochric) are found on the slopes and tops of dunes, on a part of loose tukulans with poor vegetation. And the Albic Arenosols (Gelic, Protospodic, Turbic) developed under pine forests, on the part of old tuculans, which are more susceptible to ground fires.
