Summary

Studies are dedicated to irrigation water unproductive losses reduction during irrigation, prevention of subsidience and suffusion under new lands irrigation, water-land resources productivity increase in specific conditions of lands inclined to suffusion, and ecological situation improvement. Climate is continental. Soils - light loam and sandy loam with gypsum content, subsidient. EPP area - 105 ha (net). Irrigation network - concrete flumes, efficiency 0.9. EPP is equipped with measurement devices. During process of studies agrarian-technical approaches of preventing subsidience and suffusion as well as furrow irrigation technique and technology and constructive elements of irrigation network with irrigation devices for specific conditions of subsidient soils were perfected. Set of measures on preventing subsidience and suffusion under irrigation on hardly reclaimed lands was developed.

Key words
