The duration influence of the liman flooding of the river Tanalyk flood plain waters on the water and physical properties, salt regime of meadow-chernozem alkaline soils, composition and productivity of natural grasslands in steppe Zauralye is studied. It is shown, that 30-day flooding on limans in comparison with non- or short-flooded areas leads to partial desalination of root-inhabited layer, deterioration of the main indicators of water-physical constants, increase of productivity and herbage quality of its composition.
