Abstract
Introduction . The main rice fields in the Republic of Adygea are located in the Shovgenovsky, Teuchezhsky, Krasnogvardeysky and Takhtamukaysky districts; the soil cover there is represented by meadow, meadow-chernozem, meadow-marsh and alluvial-meadow soils, exposed to anthropogenic factors. The goal of the research was to conduct a soil-agrochemical assessment of the meadow-chernozem soil of the left bank of the Kuban River, used in rice crop rotation. The objects and methods of the research . The studies were conducted on the meadow-chernozem soil of the Chibiyskaya irrigation system on the left bank of the Kuban River and included profile-morphological, field, analytical and statistical research methods. The results . It was established that leaching processes predominate in the meadow-chernozem soil of the left bank of the Kuban River, used in rice crop rotation. These processes lead to a 12% decrease in clay fractions, 23% decrease in mobile phosphorus, 2.4-2.7% decrease in exchangeable Ca2+ and Mg2+ cations, and 0.87-4.48% decrease in carbonates in the arable horizon. Conclusion: Due to the development of eluvial-gley processes in the meadow-chernozem soil of the left bank of the Kuban River, used in rice cultivation, hydromorphic characteristics are enhanced, as are the leaching of carbonates, clay fractions, mobile phosphorus, and iron. Compaction of the arable and subarable horizons occurs, necessitating monitoring of their fertility and adherence to scientifically sound fertilizer application practices.
