AB The paper asseses knowledge about dynamic changes of soil cover by anthropogenic influences. A dynamism of changes is evaluted with a comparison of the first soil survey realized in the investigated area in the year 1962 and the present state on the base of survey in years 2002-2003. The fundamental conclusions are:* the dominant long-term historical influencing factor of a negative soil anthropization exerting in precollectivization era of the past century was a tillage and a cultivation after the declivity. A cultivation according to the contour line occurred on maximum area of 15% at slopes to 6 grades (it was found out on the base of aerial photographs from the year 1938 and maps of investigated area),* modal chernozems are conserved only at slopes to 2 grades,* sloupes to 7 grades have largely eroded tchernozems and slopes above 7 grades have largely regosoils on loess,* leptosols and anthrosoils are extended on areas after total erosion of loess, a occurrence of fluvisoils and phaeozems.The previous found out facts give this evaluational prognosis: substitution of modal chernozems will be reduced and eroded chernozems, but above all regosoils, will be extended, on slopes above 7 grades will dominate leptosols and anthrosoils.
