Effects of overliming on the nutritional status of grapevines with special reference to micronutrient content

Aluminium plays a central role in soil acidity, which is one of the main constraints on grape production humid, northern temperate viticultural regions. To decrease acidity vineyard soil, it usually amended with alkaline materials that provide conjugate bases to weak acids (liming). However, practical consideration danger overliming, has potential implications terms yield reduction and decreased bioavailability several mineral nutrients. The aim this study was evaluate effects overliming using dolomitic lime grapevines growing acid soil. topsoil fertility parameters (0–30 cm), petiole berry nutrient levels, weight must quality properties were studied planted Vitis vinifera L. cv. Mencía for three years (2014–2016). Data analysis performed mixed model took into account both random (year sampling) fixed (liming treatments) showed manganese content leaf tissues. Until now, nothing known about vine nutritional status harvest properties, thus fills an important knowledge gap.
