Статтю присвячено аналізу трансформаційних процесів в ґрунтах на постзрошуваних та незрошуваних (контрольних) ділянках. Встановлено етапність відновлення низки показників ґрунтів в стадії постіригаційної еволюції, виявлено тенденції зміни гумусованості чорноземів. Обґрунтовано необхідність комплексного підходу до реабілітації деградованих чорноземів, запропоновано низку заходів протидеградаційної направленості. Отримані дані підкреслюють важливість врахування історичного досвіду антропогенних впливів для запобігання майбутнім прорахункам у меліоративній практиці.
Problem Statement and Purpose. The long-term impact of industrial-scale irrigation on the pedosphere often leads to irreversible degradation of soil properties. This study focuses on the post-irrigation evolution of Southern Chernozems within the Danube-Dniester Irrigation System (DDIS), where the use of mineralized water previously triggered secondary alkalinization and physical degradation. The purpose of this research is to evaluate the transformation processes in these soils following the cessation of irrigation and to determine the potential for natural recovery toward a state of dynamic equilibrium. Data and Methods. The research is based on systematic data collected over three decades (1993–2025) from the Trapivka monitoring site in the Odesa region. The study utilizes a comparative-genetic approach, analyzing soils from previously irrigated (DSS-2) and adjacent non-irrigated (control, DSS-2B) plots. Laboratory-analytical methods were employed to determine humus dynamics, soil pH, salinity levels, and the status of the soil adsorption complex. Statistical analysis was applied to quantify changes in soil parameters over the post-irrigation period. Results. The study reveals that the transition from irrigation to dry-land farming triggers a gradual natural recovery process. A steady upward trend in humus content was observed, indicating a positive activation of humification processes in the post-irrigation phase. However, the recovery of physical and chemical properties remains significantly delayed; specifically, residual signs of sodium-induced alkalinization persist in the sub-surface horizons decades after the termination of irrigation. The research substantiates the necessity of a comprehensive, multi-faceted approach to the rehabilitation of degraded Chernozems. Furthermore, a set of measures — such as the integration of leguminous crops, cover cropping, and the return of plant residues to the soil — is proposed to intensify the anti-degradation effect. The findings emphasize that historical experience with anthropogenic impacts is critical for informing sustainable land management and preventing future errors in land reclamation practices.
