Water supply equipment and technology irrigation in difficult conditions of desert-steppe zones

The article deals with the issue of water-saving anti-erosion technique and irrigation technology in the context of water scarcity and process of increasing land desertification, soil degradation from erosion, suffusion and subsidence of irrigation of crops in the south of Republic of Uzbekistan. In the results of use of block-humidifiers of soil polymer mixture and compaction of furrows during irrigation are given, the recommend irrigation regime and elements of crop irrigation techniques are given. Cotton irrigation regimes have been developed on the basis of humidifier blocks arranged in the soil. Installed blocks disperse moisture around themselves, create a steady supply of moisture and almost continuously provide moisture to cotton plants during irrigation periods, while increasing fertilizer productivity around humidifiers.
