Abstract

Today, there is an increase in the level of underground water and an increase in mineralization in irrigated areas. These situations have a negative impact on the agro-economic development of countries engaged in irrigated agriculture. The increase in the level of underground water and the increase in mineralization cause the acceleration of the salinization process in the irrigated areas. This, in turn, leads to the loss of soil fertility and the problem of food shortage. During the 12 months of 2023, changes in the level and mineralization of underground water in irrigated fields of Buvayda district of Fergana region were evaluated. Traditional methods and GIS technologies were used to analyze the obtained results. The results of the study show that the average monthly values of the groundwater level in the district are 2.05 m and 2.27 m in April and July, respectively, and 2.38 m in October. The mineralization level of the groundwater changed during the months as follows: it showed 2.06 g/l in April, 2.10 g/l in July and 2.18 g/l in October.
