ViNEx - The effects of urea foliar fertilisation on rhizosphere competence and root exudates of grapevine (Vitis vinifera cv. Riesling).

Project start: 01.05.2022
Project end: 30.04.2025
Sponsor: Forschungsring des Deutschen Weinbaus

The aim of the research project is to gain a better understanding of the effect of nitrogen (N) foliar fertilisation in grapevine (Vitis vinifera L. cv. Riesling) on the pattern (quality and quantity) of root exudates. This will also clarify the extent to which the potentially changing exudation pattern influences the composition of microorganisms in the grapevine rhizosphere, which in turn is relevant for the growth of the vine. The latter is due to the fact that there are growth-promoting bacteria in the rhizosphere that are literally "fed" by root exudates. This causal structure is to be investigated as a function of varying amounts of N applied to the leaves.
