Abstract
Jizzak and Hungary steppes are the largest perspective and urgent regions for irrigation construction in Uzbekistan , where the irrigation, which began 35-40 years ago dramatically changed the hydro-geological conditions of the area. The level of water table has raised up, as well as the progress of secondary salinization. This investigation aims to study the depth of ground water salinization and ground water quality composition, together with studying the geomorphological and hydrogeological properties of the soils. The quality study of the ground water including dissolvable and toxic salts, their genesis, migration and accumulation due to the process of irrigation during many years.
Mechanical composition some physical and chemical characteristics of the soil were examined. Soil salinity was widely analyzed concerning, salt quality, quality, dissolvable and toxic salt until the 1 m depth.
For the first time, in condition of new irrigation of the massive the new soil-reclamation conditions are being revised. The depth of layer, mineralization of ground water and structure of soil layer were defined. In dissertation work made and practical recommendations were given.
