Purpose of the study: to identify the features of chernozem humus profiles of the river Ob left bank within the Priob plateau (south of West Siberia) and the reasons that determined their diversity. Place and time. The south of West Siberia (Topchikhinsky district of the Altai Territory), the north-eastern part of the Priobsky plateau, the steppe zone of the Pre-Altai province of the Kulundinsky-Aleysky district, the key site "Volodarka" on the eastern edge of the Porozikhinsky-Aleysky ridge (52°41-42' N and 83°38'E). Sampling was carried out annually in August. Methodology. The collection and interpretation of materials are based on the principles and rules of the systems approach and soil ecology. The objects of study were southern and ordinary chernozems confined to different parts of the Volodarka key site (according to the soil classification of 1977; these classification names of soils are used in the text; according to the new Classification of Russian Soils (2004), the soils belong to the subtype of migratory-mycelial and textural-carbonate; according to WRB-2015 they are in the reference soil group Chernozems with the qualifiers calcic and siltic). The characteristics of humus profiles were obtained using traditional methods. All methods of analytical and instrumental study of humus and its individual components were identical. Methodological features of the research include detailed sampling (every 5–10 cm or less within the visual boundaries of the horizons) in late summer and the absence of strict methods for purifying preparations from mineral impurities. In this work, the concepts of “humus” and “system of humus substances” in soils are used as synonyms. Main results. The humus profiles of the chernozems of the studied territory, currently functioning under the same conditions, have a significant variation in characteristics, representing a range of options typical for such soils (when, based on the combination of characteristics of elementary humus-forming processes - EHP - the upper part with the ... |
