Annotation:
Agrogenically transformed soils in the mountain forest-steppe of Western Transbaikalia have been investigated. The morphological, chemical and physical properties of the Ap horizons 10–15-year old fallow lands have been studied. There is an increase in the content of organic carbon and exchangeable cations in agro-dark humus horizons. Soil pH decreases towards acidification. There is an increase in the content of the silt fraction in grain size distribution in soils. The structural composition of agro-dark humus horizons in two key plots is generally favorable due to the predominance of agronomically valuable fractions 0.25–10 mm. The water-stable structure of the agro-dark humus horizon of key plot 2K-13 is good and unsatisfactory of key plot 1M-13. The main stages of restoration of the fallow lands vegetation are revealed. The shrub stage of the steppe meadow reflects the next stage of demutation of steppe vegetation and further forestation of the territory.
Keywords:
