Abstract
Nanofertilizer is based on microscopic particles that are more easily absorbed by the plant and metabolized more quickly. This is not only about the effect as a fertiliser, but also phytosanitary aspects were considered. Fertilizer of copper and silver in nanoform was applied four times during a growing season in a Pinot noir vineyard. The effects on the grapevines were examined regarding nutrient supply, yield, health performance and wine composition. In addition, several wine tastings by means of a panel were used to try to perceive differences. No improvements could be recognized concerning health status of the plants. Despite larger changes in metabolites as propionic acid, limonene oxide, Cis Eugenol, Gujacol, some phenols and esters the sensorial evaluations do not result in huge changes. In general the wines could not be sensorially differentiated.
