DEVELOPMENT OF A SOIL DEGRADATION MAP OF THE SHAULDER IRRIGATION MASSIF

Abstract

Currently, the problem of their reclamation status has sharply worsened in irrigated areas, the areas of so-called "unused", "waste" lands have increased. Currently, these areas are gradually populated with the formation of salt marshes, overgrown with halophytes and, like the dried bottom of the Aral Sea, become sources of Aeolian salt transport. Thus, the problem of deterioration of the reclamation condition of the soils of irrigated massifs is an urgent problem today, and their solution is one of the priority tasks of soil and biological science. Based on the above, the main purpose of the work is to study the current state of "fallow" secondary saline soils that have left agricultural circulation using the remote method. As a result, a reconnaissance survey of the territory of the irrigation array was conducted and representative subsatellite territories were selected, where traditional ground salt and satellite surveys of subsatellite territories were carried out synchronously in place and time, and also the input of the received data into the spatially coordinated database (DB) of the array information system was carried out. The current state of the soil cover of the Shaulder irrigation massif was also assessed and a map of soil degradation was compiled. Methods of comprehensive monitoring of soil fertility and their impact on crop yields based on satellite data developed as a result of the implementation of the work can be used in other arid regions of the world.
