The liman flooding duration influence on some soil properties and productivity of natural grasslands in steppe Zauralye

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.
