Pilot 1: Precision Viticulture - Spain

Precision Viticulture (PV) is a key concept on the wine-growing sector. The main purposes of PV are the appropriate management of the inherent variability of crops, an increase in economic benefits and a reduction of environmental impact. Variable-rate application (VRA) of inputs and selective harvesting at parcel level are productive strategies which provide significant benefits for farmers in general.

This pilot will take place in Spain, in the region of Galicia, province of Pontevedra, in Bodegas Terras Gauda. The fundamental tasks to perform are:

1) Initial zoning of the parcels, based on known geo-climatic and topographical information, with the aim of identifying areas with similar productive potential and evaluating the opportunity for their similar management.

2) Selection, installation and management of sensors and monitors, VRA equipment and machinery. FOODIE will provide tools for GIS and data analysis and will be complemented with other technologies as GPS and DGPS, crop sensors and monitors, local and remote sensors, VRA equipment and machinery.

3) Quantification and evaluation of within-field variability through:

a. Plant Vigour Maps obtained by Hyperspectral Sensor Flights.
b. Measurement of Soil variability by Electromagnetic Mapping.
c. Open Data available and relevant for the project.

The analysis will integrate, in addition to local gathered data, available data from different sources as:

  • Land satellite images
  • Environment and biodiversity
  • Agro-food statistical indicators
  • Measures of final grape production and wine quality, depending on the initial zoning
  • Zoning review in accordance with the results for a new zoning of the parcels to refine the model.
  • Vineyard exploitation using novel productive strategies.

Data sources

The Spanish pilot will include data from 56 agro-meteorological stations dependent on the Department of Environment of the Regional Government of Galicia. Those meteorological stations provide daily measurements of:

  • Soil temperature
  • Air temperature
  • Dew temperature
  • Mean relative humidity
  • Hours of leaf wetness
  • Soil humidity
  • Global solar radiation
  • Sunshine hours
  • Wind speed and direction
  • Rain and barometric pressure

The pilot could also include public information from the Areeiro’s Phytopathological Station, which will carry out, among others, sensory analysis of fruits and of pollen viability.

Estimated values obtained

  • Operational costs reduction (cost savings thanks to irrigation reduction)
  • Production optimization (increase of productivity taking vineyard vigor into account, or grant funds obtained by changing crop species after a FOODIE recommendation)
  • Risk prevention (FOODIE recommends a phytosanitary treatment which avoid crop loss)
  • Environmental impact reduction (i.e. reduction of fuel and electricity consumed by
  • Machinery.
