Abstract

This study provides a comprehensive assessment of soil salinity levels and their driving factors in irrigated agricultural lands of the Gulistan massif, Mingbulok district, Namangan region. The results indicate a substantial extent of salinization: out of a total area of 4966.53 hectares, 51.46% of soils are moderately saline, 26.28% are slightly saline, while 4.77% and 3.79% are classified as strongly and very strongly saline, respectively. The analysis identified key drivers of salinization, including a shallow groundwater table (1.5-2.0 m), low efficiency of drainage systems, and high evaporation rates. The spatial distribution of salinity is strongly associated with the water regime and the condition of meliorative infrastructure. Based on the findings, scientifically grounded approaches for salinity management are proposed to improve soil reclamation status and enhance the sustainability of agricultural production systems.
