Abstract
This article presents the results of assessing irrigated soils in the “Chorbakir” massif of Bukhara district using digital maps of mechanical composition, humus content, nutrient elements, salinity indicators, and the Soil Quality Index (SQI) method. According to the assessment results, the index value of irrigated soils distributed within the massif ranges from 38 to 47.9, which corresponds to low and medium quality groups.
