Innovative technologies in the effective use of water resources

Abstract

Abstract Global warming in the arid region is currently exacerbating water scarcity. The use of groundwater for crop irrigation is one of the major problems in the world. In this context, the use of rivers and ponds with varying degrees of mineralization is especially important for the irrigation of crops. About 300 km 3 /year of collector-drainage water (CDW) is formed in the world, which causes great damage to the economy and nature of all countries of the world. In this regard, one of the important tasks is the development of measures for the reuse of collector-drainage water for irrigation, the first demineralization, and disinfection, or their use in combination with river water. To solve these problems, a neutron-active analysis of the composition of the soil and trace elements were studied, as well as the dynamics of the distribution of water in the active soil layer to determine the patterns of water absorption in active soil during irrigation based on a new innovative method of nuclear physics and irrigation of cotton plantations with the addition of drainage water and as a result of which, there was provided the efficiency of water use and increase the productivity.
