This research focuses on determination of irrigation — drainage networks conditions, salinity of irrigated areas in Shavat district of Khorezm region (Uzbekistan) by geospatial analysis and giving recommendations for their elimination. Additionally, obtaining monthly ground truth data from observation wells and interpolate them with IDW interpolation algorithm methods of Geographic Information Systems (GIS) technologies in order to monitoring changes of groundwater level and mineralization in vegetation period of main agricultural crops are highlighted. Besides that, by using remote sensing technologies, the obtained data about the irrigation regime was determined in agricultural areas. As a result of the usage of GIS and RS methods, there have been created thematic maps on analysing salinity of soils, the actual condition of irrigation and collector of networks, actual level and mineralization of groundwater as well as their dynamic changes. On the basis of the obtained results, there have been given recommendations for improving the conditions of ameliorative arable lands on keeping the level of groundwater at a specified depth and cultivation of agricultural crops in periods of water scarcity.

Proceedings of the International conference

The article presents the results of scientific research on the use of magnetic technologies for water magnetization and their use in agriculture. On the beneficial effects of magnetic water on the rate of plant growth, the construction of the root system, and the potential for strong plants in the future. The research results proved that soaking seeds and watering with magnetized water lead to an increase in crop yields with a simultaneous decrease in the specific water consumption for irrigation by 1.5-2.0 times. The article also shows the results of field studies conducted at the site where the drip method of irrigation of cotton has been introduced using water for irrigation that has passed through a magnetic device. The magnetic apparatus used to magnetize the water in the experimental area is described, along with its design and working principal. Field research was done on meadow - serozem soils in the Kuyichirchik area of the Tashkent region to examine the impact of magnetic water on the growth, development, and increase in yield of cotton while conserving irrigation water. The outcomes show a favorable impact on the growth, development, and increase in cotton output. At the same time, water savings amounted to 10-20 percentage compared to irrigation with ordinary water.
