Working – out the maps for humidity excess required for the drainage works from the year 1970 was made based on the pedological studies of that period when, Gleysoils Eutric and Mollic was consider to cover very large areas. The actual studies reveal for Gleysoils Eutric and Mollic a much smaller surface and as a consequence a demand for the drainage and humidity excess works very reduced. The paper presents the expansion, properties and causes that led to the formation of Eutric and Mollic Gleysoils in the Down Plane and also the required improving measuresumiditate necesary.
