Immediate effects of reduced tillage on soil health in a rainfed vineyard under Mediterranean conditions

Vegetation covers emerged as a sustainable alternative to tillage in Mediterranean vineyards due to their beneficial effects on soil health. However, grapevine growers remain concerned about the establishment of these covers as they may compete with vines for water and nutrients. Recent studies sugg...
