Description :
In the region of Navarre, 7 rain-fed vineyards of different ages (between 22 and 61 years old) were selected as experimental plots. The proposed approach used a botanical signal, grafting callus, and determined the topographic changes caused by the erosion processes in these fields. This innovative way of determining overall rates of soil surface changes in grafted vineyards appears to be a promising method to estimate long-term erosion/sedimentation rates not only in vines but also in other crops, providing a reliable botanical benchmark of the former soil surface.
