Maintenance of optimal soil-hydrologic conditions upon irrigation of dark chestnut soils in the Transvolga region

摘要

Data on the water budget of irrigated dark chestnut soils in the Transvolga region obtained during the 20-year-long experimental study of temperature and water regimes with application of tensiometers are analyzed. The water conductivity coefficientsare shown to depend on soil moisture, runoff volume, infiltration, and evaporation measured by different methods including the hydraulic balance-meters.
