The proposed methodological recommendation on the ground support of remote methods for assessing salinization of soil in reclaimed lands is devoted to the operational monitoring of salinity of reclaimed lands. The assessment and forecasting of cotton yield in the Hungry Steppe and the lower reaches of the Amu Darya, by direct signs of determining salinity at farms, a separate irrigated plot, based on remote information (aerial and space photography - APS and KFS). The task of the under investigations study is visual assessment of soil salinity level by indirect signs: condition of crops, fall of plants, salt bloom, etc. The results of the established check are recorded in the field journal. Salinity map with salinity contours; slightly saline, moderately saline and strongly saline soils are created based on the studied research materials. Number and location of the main sites for determination of soil salinity features are determined on the basis of analysis of the research materials determined with involvement of other available materials on the soil cover characteristics. Classification of soils according to the degree of salinity is carried out according to the formula WP = PVU + VJp; WP = 51.42 - 96.28 Jp ± 1.12 g ha-1. It is presented in Table 2 for Amu-Darya lower reaches (Khorezm province and the Republic of Karakalpakstan), where + Y - yield calculation; PVU - maximum yield. This program is designed for use in the educational process during practical lessons on agricultural reclamation directions.
