Soil and foliar fertilization affects mineral contents in Vitis vinifera L. cv. 'rebula' leaves

Grapevine nutrient oversupply as well as shortage can both result in unbalanced vine growth and poor grape production. Mineral fertilization is a powerful tool also in viticulture in order to increase yields and improve grape quality. The trial carried out in Slovenian winegrowing region investigate...
