- Аннотация: The data obtained show that the modern agronomical utilization of Humic Gleysols in an undrained atate take place inder conditions of a natural, very unstable water regime. This leads to practically complete soaring of the yield of grain crps in wet years or its decrease in moderate and dry years. It is established that drainage complitely eliminates the formation of the two-stage perched water tabke which is typical of these soils under natural conditions. On drained Humic Gleysols conditions form which are favorable for the cultivation of crops of field rotation, especially grain crops. The tendency of more intensive influence of non-trench plastic drainage on wetness regime of these soils is established.
