The mountain and taiga soils of the national park “Alkhanay”

The variety of mointain and taiga soils of the National park ‘Alkhanay”. The soils cuts were made on slopes of Daursky and Mogotuisky mountain ridges, on different altitudes under different plant asso ciations of river Ilya valley. It was found out, that south exposition slopes Daursky mountain ridge are characterized by very varied and contrasting soil and plant cover. Under sparse pine forest in the middle of the slopes are formed sod-podburs and illuvial-ferruginous. Brown litogenic soils are formed on relief low part of slopes (uburs) under steppen xerophytic-forb associations. Rusting pyrogenic rude humus and humus soils take the upper parts of the slopes, as well as lower gentle slopes.The slopes of the shadow exposure in the mainare occupied by rusting soils little humus. Soils of the valley of river Ilya are presented by types: alluvial gray humic (turf)alluvial meadow cryogenic deformed and alluvial silt-peat swamp.
