Summary

Study is directed to development of set of measures on secondary salination prevention based on leaching irrigation ragime, drainage strengthening,   subsurface  drainage  construction;  definition  of water-salt    balance    formation, drainage effectiveness and workability. Plot is located in semi-desert conditions. Soils: sandy loam and miidle loam, saline, chloride-sulfate. Plot area is 60, 150 and 3200 ha. Irrigation network: flumes; irrigation from flexible horses. Drainage network: collectors with depth 3-6 m, closed horizontal drains with depth 2.5-3.5 m. Scientific grounding of water-reclamation measures on reclamation  regime  improvement,  irrigated  lands  productivity increase, water saving and secondary salination prevention is made.

Key words
