 An information-analytical report of the possibilities of rice cultivation in different landscape conditions was formed. It describes the characteristic of rice irrigation systems and determined a possibility of rice growing in drip irrigation conditions and contour systems on 180 thousand hectares in Kherson region, 40 thousand hectares in Odessa region and about 3 thousand hectares in Nikolaev region. Peculiarities of morphological structure and structural-aggregate composition of the arable layer of dark-chestnut saline, meadow-chestnut saline and meadow saline soils which have been used for rice cultivation more than 50 years, were determined. The redox regime and the dynamics of the main indicators of fertility of the most common soil types in the rice growing zone of Ukraine with different technologies of rice cultivation are described. A series of maps on the spatial distribution of soil condition indicators in rice crop rotations was developed by humus content, easily hydrolyzed nitrogen, mobile phosphorus and potassium, pH, absorbed bases, exchangeable calcium and magnesium, total iron in the arable soil layer (0-20 cm). Particularity of salt regime of rice field were determined for different rice growing technologies. Models of salt composition qualitative of the aeration zone of dark chestnut saline, meadow-chestnut saline and meadow saline were done and based on date of monitoring investigation.Forecast models of rice irrigation systems groundwater regime have been developed. The qualitative composition of irrigation and drainage-discharge water of rice irrigation systems has been studied.The criteria for normalization of reclamation loads on the paddy soil are determined. A method of normalization of reclamation loads in rice systems according to indicators of soil cover condition (Pat. for utility model № 131329) was developed. The recommendations "Paddy soil soils and directions of their use" and scientific and methodological recommendations "Criteria
