Abstract
The specificities of leaching (outflow) of chemicals from soddy-podzolic loamy deeply gleyed soil by infiltration and its return from groundwater during their evaporation are considered in the paper. In the annual cycle calcium is the element which is mostly washed out with amount of 89…106 kg/ha. It was shown that potassium (15…14), manganese (13,6…9,3), zinc (13,6…7,7), calcium (7,5…5,2) and magnesium (7,1…4,7) in percentage of the outflow return in the soil with the capillary rise of groundwater.
 It is shown that the ratio of infiltration (I) and evaporation of groundwater (K) in soddy-podzolic soil is within the range of 0,3…0,6 for medium arid, 2,6…2,9 for average long-term and 2,6…2,9 for humid conditions of atmospheric moistening. Thus, the lowest values of ratios for medium arid, and the highest ones – for medium humid conditions, which reflects the real specificities of the infiltration and evaporation of groundwater in natural conditions.
