WORLD CONGRESS OF VINE AND WINE, 39., 2016. Ibravin, Embrapa Uva e vinho, Governo do Estado do Rio Grande do Sul, Prefeitura Municipal de Bento Gonçalves. 2016.c2016  aVineyard soils of the Campanha Gaúcha region of Rio Grande do Sul are sandy and have low to medium organic matter content, displaying low natural ability to supply nitrogen (N). Therefore, maintenance of cover crops is essential or the protection of the soil surface from the impact of raindrops and water erosion. The application of nitrogen fertilizers is also necessary. However, cover crops can absorb part of the nitrogen applied in the soil, decreasing the availability to young vines, which may slow the growth of root and shoot, and thus, the beginning of grape production.  aUva  aVinho  aFERTILIZER NITROGEN  aGrapevine1 aCERETTA, C.
