    Limassol Project Meeting, 16/11/2016, Eratosthenes Research Centre

    Established 1983, also first vintage.

    Vineyards first planted 1976.

    Approximately 25 vineyards through out the

    Golan Heights.

    ̴ 650 hectares (1600 acres).

    Divided and cultivated to approx. 430

    blocks (averaged block,1.5 ha).

  • What is precision viticulture?

    Limassol Project Meeting, 16/11/2016, Eratosthenes Research Centre

    Precision viticulture is precision farming applied to optimize

    vineyard performance, meaning maximizing yield and quality while

    minimizing environmental impacts.

    This is accomplished by measuring local variation different factors like:

    soil, topography, microclimate, vine health, vegetation etc. and then

    applying appropriate viticulture management practices.

    High in-field variability will need more detailed and precise management.

    Precision viticulture depends on new and emerging technologies such

    as environmental sensors, satellite and airborne remote sensing,

    and geographic information systems (GIS) to assess and respond to

    variability.

    is the “magic” word uniformity, WineGrowingSo, when

    Invest in designing the vineyard ahead using all

    tools available:

    • Ground soil mapping

    • Satellite images: soil reflectance, NDVI

    After establishment use remote sensing tools to

    define your variability and monitor improvement.
