Summary

Investigations related to salt control on a base of artificial drainability increase by means of different depth close horizontal drainage construction and leaching irrigation regime conduction; close drainage parameters grounding, providing minimal reclamation and technical- economic efficiency in combination with leaching irrigation regime; soil water salt regime management under conditions of AmuDarya low reaches.

Climate is sharply continental. Relief is flat.

Soils structure corresponds to loam, slightly (73%) and strongly (13%) saline.

Experimental plot area -129,6 ha.

Irrigation net is flume, efficiency -0,86

Drainage system - close horizontal,

Close horizontal drains from polyethylene pumps with circular winding from artificial protective-filtering material and additional shrouding are constructed. Close horizontal drainage parameters are scenically grounded. Recommendations on soil water salt regime management on a background of close horizontal drainage are given.

Key words
