Management of vineyards

Due to variability of soil and climatic factors, as well as the management practices, in the cultivation of vines over large surface areas, zones of non-uniform ripening of grapes can be created affecting the quality of wine. Through the concentration of carotenoid in the vegetation of stump certain conclusions are drawn concerning the degree of fruit’s ripeness and the concentration of sugars.

What Ecodevelopment could do?

  • Assessment of the point of ripeness through the concentration of carotenoid.
  • Diagnosis of plant water stressing
  • Advice and Support in vineyards’ management by:
    • Continuous monitoring through repeated remote sensing images
    • Harvest in accordance with the zones of ripening.
    • Precise irrigation in accordance with spatial data.

The diagnosis is achieved by:

  • Taking of geo-referenced multispectral images, beyond the visual spectrum, with the use of unmanned aerial vehicle.
  • Use of Geographic Information Systems (GIS)
  • Sampling of plant material for the analysis of TSS (Total Soluble Solids)
  • Statistical Analysis
