“…Since the 90s of the twentieth century, a significant part of lands, primarily low fertility, including solonetz, was withdrawn from agricultural turnover [11]. It has been shown that a long period of meliorated solonetz in fallow condition led to changes in carbonate and gypsum profiles [12][13][14], while in solonetz with solonetz horizons destroyed by treatments, the meliorative effect persisted for a long time [2]. In the present period, the question of expediency of introducing fallow lands into agricultural turnover is topical.…”

Information on the properties of unused solonetz on deposits is necessary for studying the processes of their evolution, solving the issues of rational use of agricultural lands, and establishing the possibility of their reintroduction into agricultural turnover. The aim of the research was to study the fertility indicators of solonetz (Gleyic Solonetz) in the steppe zone of Omsk Priirtyshye, which are in the post-agrogenic stage of development. The research was carried out in Cherlak district of Omsk region (south of Western Siberia) on three fallow massifs with the age of less than 10 years; 10-20 years and more than 20 years. A field survey of soil cover and soil analyses were carried out. As a research result, it was established that fallow massifs are represented by the meadow-chernozem solonetz and the chernozem-meadow columnar solonetz of different types with low fertility. The unfavourable properties of solonetz were expressed physical solonetization, high density of illuvial horizons, low porosity, and unfavourable composition of exchange-absorbed cations, alkaline and strongly alkaline environment in the middle and lower parts of profiles, which are aggravated by arid conditions of steppe landscapes. Reintroduction of solonetz into agricultural turnover can be allowed only on arrays with predominance of medium and deep solonetz for cultivation of solonetz-resistant crops under moisture-saving technologies, no-tillage reclamation treatments, and chemical reclamation in the future.

The state of artificial tree planting in 54 years after the meliorative effects on the solonetzic soils (land use, gypsum, manure application) and the transformation of annual soil treatments were studied. There was a general decrease in the forest stand and its quality on saline cells compared to common Chernozem. It is shown that the most salt-resistant tree crops are oak, ash and elm, whose safety is higher compared to other breeds tested in the experiment. Pears, apple trees, and poplars are now almost absent from the forest plantation. In the southern part of the saline section, by the age of 54, an ash-oak plantation with poplar and elm trees was formed (in the aggregate of the first two tiers), and in the Chernozem section, an oak-ash plantation with elm trees was formed. Plantings, according to forest management standards, have a significant difference in the composition of the first tier, in the completeness and totality of crowns and the stock of the stem tree. In the Northern part of the experimental site, the difference in the composition of the first two tiers is more significant, since the proportion of ash in the Chernozem section is 20% lower than in solonetzic soils, where the stand is less dense, full, stock and bonitet than the taxational indicators of the stand in Chernozem.
