Green cover between the rows of vines is important for the quality of the wine. On slopes, the vegetation protects against erosion.
In summer, green cover is wanted when there is enough rainfall. When the vines need the water, the vegetation has to be stopped.
The Güttler GreenManager is a modular equipment concept consisting of cultivator, harrow and the Güttler prism roller. In drought and water shortage, the GreenMaster simply peels off the vegetation together with soil and roots and leaves it lying there. The whole layer dries out, but it interrupts capillary action and protects against evaporation.
When there is more moisture again, the soil and plant mat can be rolled back down with the prism roller on the GreenManager, and most of the plants continue to grow. The Güttler GreenManager is a year-round machine for managing green cover in the vineyard. More information directly from Güttler or from Dr Winfried Hartl of Bio Forschung Austria in Vienna. He initiated the development of the GreenManager at Güttler.
