Abstract

This study investigates the mechanical composition and agroecological characteristics of soils in irrigated agricultural lands of the Gulistan massive, Mingbulok district, Namangan region. The aim of the research is to determine the soil granulometric composition, classify soil types, and assess their relationship with water-physical properties and meliorative conditions.

The results revealed that out of 5062.4 hectares of irrigated land, 38.92% are medium loamy, 26.40% light loamy, 21.27% sandy loam, 6.79% sandy, and 6.62% heavy loamy soils. The identified granulometric composition significantly influences water retention capacity, aeration, and nutrient dynamics in soils.

Based on the findings, the necessity of implementing differentiated land management approaches and adapting agrotechnical and meliorative practices according to soil mechanical composition is substantiated. These measures are essential for improving soil fertility, optimizing irrigation efficiency, and ensuring sustainable agricultural production.
