In 2019, monitoring studies were conducted in stationary and semi-stationary ecological areas selected from the most widely used soil groups in agriculture in the region. The study found that according to the average quantities of salts in the upper one-meter layer of the soil profile, the highest salt reserves were Recorded in irrigated hydromorphic soils of Furkat, Tashlak, Dangara, Altaryk and Yazyavan districts on average from 106 t / ha to 156 t / ha. In the region of ancient alluvial deposits in Central Fergana, due to the rise of groundwater, their mineralization is mainly 1.0-1.5 g / l, in some local areas - 3.0 g/l, in all cases consisting of sulfate and chloride-sulfate salinity types. Salts in the soil profile are dominated by Na2SO4 and MgSO4 and their quantitatively close CaSO4 salts, chlorine salts are found to consist mainly of MgCl2, rarely NaCl salts.
