Abstract
The features of the water regime of Light Gray Forest soils with diffe rent degrees of gleying in years of different moisture are examined. A two-stage perched water table forms in the profile of Gleyey soils in spring and autumn. This causes a decline in the yield of crops or the ir death. It is shown that drainage eliminates the perched water table . Ceramic trench and plastic non-trench drainage have similar agroecol ogical and hydrological influence on the examined soils.
