In order to avoid competition for water by weeds, inter-rows are often artificially maintained without significant plant cover, resulting in large areas exposed to rainfall impact (Ramos and Martínez-Casasnovas, 2006 and Tropeano, 1984). In comparison with other typical crops in the Mediterranean basin, vineyards constitute the form of agricultural land use that causes the highest soil lossesar (Mtínez-Casasnovas and Sánchez-Bosch, 2000). Tropeano (1983) measured soil losses of more than 1800 g m−2 per event in vineyards in northern Italy, at a very local scale using Gerlach troughs. In that context, Martínez-Casasnovas and Ramos (2006) related the importance of on-site erosion effects on the final budget of the vine-growers. Cerdan et al. (2006) analyzed an extensive database of medium-term (3–20 years) soil loss measurements under natural rainfall at the plot scale. The authors concluded that vineyards are the agricultural land use that causes the highest soil loss in Europe.
