Résumé
Steep slopes, erodible soils, rill and ephemeral gullies, compaction due to wheel traffic and humantrampling are common features in vineyards around the world and result in high soil erosion rates.However, little is known about seasonal and spatial variations of soil erosion rates due to factors such asthe impact of the vine plantation, harvest, and tillage on the soil redistribution over the long-termtemporal scale. The goal of this study is to assess long-term soil erosion rates and the impact ofmanagement on sediment and runoff yield by means of Gerlach troughs and a topographical approachbased on botanic benchmarks in two paired vineyards with different ages (3 and 35 years) located on thehillslope of the Ruwer-Mosel Valley (Germany). We studied: i) soil profiles and properties at differenthillslope locations and ii) soil redistribution and erosion by means of topsoil level maps applying botanicbenchmarks using the Stock Unearthing Method (SUM), RUSLE (Revised Unviersal Soil Loss Equation) andGerlach troughs. The SUM showed that the old vineyard’s erosion rates ranged from 3.3 to 3.8Mg ha1 yr1, which was similar to the Gerlach trough measurements, and we demonstrated that the soilerosion rates depended on rainfall characteristics and human disturbances due to tillage, harvesttrampling, and compaction by heavy machinery. Data from the SUM in the young vineyard showed 62.5Mg ha1 yr1 of soil loss, which is a consequence of severe soil disturbance during the planting of the newvineyard. Finally, to prove the reliability data, RUSLE showed higher soil loss in the young vineyards(19.46 Mg ha1 yr1) than in the old ones (11.28 Mg ha-1 yr-1).
