Description :
In this paper, the AA. characterize the long-term effect of reforestation on the stabilization of soils affected by strong gully erosion in Prietrž village in South-Western Slovakia. Permanent gullies there were reforested a century ago with the black locust (Robinia pseudoacacia). Reforestation measures induced soil profile development on the gully slopes with distinct humus horizons. The overall effect of the observed changes is an increase in the aggregate stability of these reforested gully soils. The values determined for these gully soils do not differ significantly from those in the surrounding non-eroded agricultural soils. The extreme difference in aggregate stability between the topsoils and the parent marl material is responsible for this landscape's susceptibility to severe gully erosion.
