The authors investigated the light soils of eroded soils in Ginawa (voivodeship zachodniopomorskie). These soils had been the fallows from eight years. It was found that, the absence of agriculture use caused the decreasing of soils fertility. The most unfavourable changes applied to humus horizon of these fallows. The authors ascertained the decreasing of pH reaction and Mg available content and the increasing of activity of Al3+ exchangeable form in this horizon. Among the investigated soils, the delluvial soil (from slope foot) became the most degraded. It had the very low pH reaction and relatively the high content of Al exchangeable form. The soil from slope mouth had relatively less changed fertility
