“…The groundwater level does not remain constant, but varies seasonally, upon leaching and irrigation and changes not only in their level but also in mineralization (Lebedeva and Kutovaya, 2013;Lyubimova and Novikova, 2016). Grabovskaya (1954) suggested the notion of a critical regime of groundwater salinizing the soil.…”

The optimal depth of the groundwater table and the water-salt regime is of importance in the postmeliorative period. The scope of these studies is to provide scientifically grounded assessment of previously reclaimed soils (water irrigation with a total norm of 5000 m 3 /ha under conditions of deep horizontal drainage, 1986-1989) in the postmeliorative period of 2015-2016 and to develop parameters for forecasting their meliorative regime. This work was conducted with the use of traditional ground-based methods of soil research. As a result of the research, data were obtained that allow assessing the water-salt regime, groundwater levels, their mineralization, as well as changes in the physical and hydrophysical properties of the previously reclaimed meadow solonchaks under natural conditions and under alfalfa in the background of deep, horizontal drainage and developing soil biota control techniques, including improvement of the meliorative state of the soil and indicators of their effective fertility.

“…Since the 90s of the twentieth century, a significant part of lands, primarily low fertility, including solonetz, was withdrawn from agricultural turnover [11].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.
