Abstract	In the Rougiers de Camarès area (south of Massif Central), hydric erosion leads to degradations of infrastructures and hillslopes cultivated soils. The objective of our work was to assess the effects of tillage and manure types on soil sensitiveness to erosion, or erodibility. Experimentations were set up on oat plots, in order to assess the effect of five tillage and three manure or fertilizers types on cultural profile (structure), soil carbon content, runoff and erosion under rainfall simulation as well as yields. Tillage methods were conventionnal flat moldboard plowing, flat moldboard plowing with mulch, raised moldboard plowing, superficial tillage (cultivator) and direct drilling. Manure or fertilizers types were raw and composted farmyard sheep dung (3 O t/ha) and NPK fertilizers (70-40100). We observed many large hard clods on cultural profiles after raised moldboard plowing, whereas structural profiles after direct drilling were only slightly differenciated. Topsoil (0-10 cm) carbon content remained high aRer superficial tillage, direct drilling and organic supply, but decreased after moldboard plowing. Rainfall simulation on bare soil led to high
