Abstract (English):
The article is devoted to the dynamics of moisture reserves in southern chernozems and the assessment of moisture exchange in the active, root-habitable soil layer under various alfalfa irrigation regimes. The studies were carried out for various humidification regimes with the maintenance of pre-irrigation soil moisture of 90,85,80,75,70 and 65% of the soil moisture in lysimeters, as well as at a pilot production site irrigated by Kuban-M wide-range sprinklers. This is due to the fact that the irrigation regime of agricultural crops must meet environmental requirements, one of the main of which is to moisten the soil with the least infiltration discharge of irrigation water into the underlying soil layers.
