The purpose of the research is to assess the natural and reclamation state of irrigated lands, which reflects the type and intensity of soil fertility decline associated with the violation of their hydrochemical regime during irrigation development. Improvement of the assessment was carried out on the basis of balance-analytical and statistical methods that have been tested in the Republic of Karakalpakstan. At the same time, the patterns of spatial variation of soil salinity, depth, and mineralization of groundwater obtained by the authors were taken into account. A new scientific approach to assessing the ameliorative state of irrigated lands is substantiated by the depth of occurrence and mineralization of groundwater, which are indicators of the manifestation of salinization and waterlogging of soils.
