Laucha, Germany (October 06, 2014) – Vines have been cultivated since AD 998 on the hillsides lining the Saale and the Unstrut rivers which lend their name to the small, but growing, Saale-Unstrut region. It is among the northernmost of Europe’s traditional wine regions. Due to this and the cooler climate, the weather is more variable than in the regions in the west. As such, many of the vines are planted on labor-intensive stone terraces that help temper the climate. Yields are low and Spätlese or Auslese can be produced only in exceptionally warm years. The wines are labelled as varietals and, with the exception of extremely rare dessert wines, all wines are vinified dry and have a refreshing acidity.
The aim of this study is to evaluate the effects of ferti-activator Sanbio PLANTA on productivity and quality of vine variety ´Portuguese´ and ´Silvaner´.
This study was executed in cooperation with the winegrower Wolfgang Voigt, located in Laucha, Saale-Unstrut region, Saxony-Anhalt, Germany.

Figure 1. Yield calculated as weight of grapes per vine plant (kg)
The yield calculated as weight of grapes per vine plant was increased by +0.208 kg/vine plants, resp. +15.7% of Portuguese
+1.37 kg/vine plants, resp. +22.6% of Silvaner.

To summarize, the present study shows significantly positive effects of ferti-activator Sanbio PLANTA on productive performance of vine.
The positive effects at glance:
- Higher harvest
- Higher sugar content.
