Use of proxy sensors to characterise spatial variability on agroforestry vineyards
Abstract
Planting intercropped trees with grapevines is a practice that have recently been developed in French vineyards in order to bring beneficial effects to the parcel and its environment. The expected positive effect are an improvement in aerial and soil biodiversity and mitigation of climate extremes like wind or temperature. The competition for resources between trees and grapevines is the main issue from an agronomical point of view. We are currently studying two nine-year-old parcels trained on agroforestry in a Bordeaux vineyard (variety Merlot for aging premium wine) and in a Gascony vineyard (variety Sauvignon Gris for basic fruity white wine). We use proxy sensors to characterize the spatial variability of these vineyards. The sensor NDVI Greenseeker and the laser sensor Physiocap are devices mounted on a quad bike that allow the measurement of the vine vigor evolution on a whole plot. The collected data is coupled with targeted samplings to determine the crop load and the maturity of grapes. The first results on our measures show that trees have no direct effect on the grapevine vigor after nine years of co-planting.
