Summary

Study is devoted to land uneven subsidence under field surface moistening, providing even of subsiding deformation on new developed irrigated lands and cost reduction for field preparation. Climate is continental. Relief is hilly. Soils-sierozems, sandy-loam. Ground water level is more than 10 m; brackish sulfate-chloride. Irrigated area is 1.5ha. Water supply is implemented by earthen  canals,   irrigator efficiency 0.87-0.89; drainage network is closed. Recommendations are developed on subsiding soil irrigation with maximum evenness of field moistening

Key words

Irrigation network, irrigation technique, furrow, cotton
