Erosion and gouging (lat. erodere = to gnaw away) of the earth's surface by flowing water, wind or glaciers. In viticulture, this is a consequence of large-scale monocultures. Vineyards are often planted on slopes, so the earth's surface is constantly carried downhill by rain and wind. To stop erosion, targeted cover crop is often done to give the earth's surface support. In some wine-growing areas such as Burgundy, Moselle and on the Rhine, the earth is carried back onto the slope in baskets. On steep slopes, terraces with retaining walls prevent erosion. See also the list of relevant keywords under soil type and vineyard care (means and measures).
For me, Lexicon from wein.plus is the most comprehensive and best source of information about wine currently available.
