Precision viticulture: using on-board sensors to map vine variability and characterize vine trajectories

Abstract

Precision viticulture consists in using ICT (Information and Communication Technology) to implement more specific and better targeted technical vine practices. With proxy-detection, precision viticulture mobilizes on-board sensors, computers, and GNSS positioning. Three sensors were embedded on a tractor and tested on a plot with three champagne grape varieties. This plot is located at the Plumecoq experimental vineyard (CIVC, Champagne, France). The first sensor is a pruning wood sensor (Physiocap) designed and developed by CIVC. Physiocap is used during dormancy season to characterize vine architecture by measuring shoot vigor, shoot number and biomass. The other two are growing season sensors. GreenSeeker Trimble provides a vegetative vine index by measuring foliage porosity. Multiplex Force-A characterizes vine metabolism through chlorophyll, anthocyanin, flavonol, and nitrogen leaf content. Data from these sensors define the physiological state of the vine at the time of measure. The sensors can also map spatial vine variability within a plot or between plots. To understand the vineyard as a whole, the combination of biomass indexes and leaf contents is interesting. In this case, there was some good correlation between the indexes and yield and must compounds such as nitrogen, acidity or sugar. By collecting sensor data at several key stages, it is possible to plot vine trajectories. Vine trajectory describes the physiological developments made by the vineyard according to its initial potential. It depends on annual climatic conditions and physical environment. Vine trajectories are useful to understand the effect of year and terroir.

Enological, economical, social and viticulture ”terroir” units as fundamental elements of mosaic of “big” zoning

Nous savons tous très bien qu’on a assisté au cours de ces dix dernières années à une éclosion soudaine de recherches sur le zonage viti-vinicole qui, à partir par exemple du modèle du concept de “terroir”, se sont de plus en plus enrichies en passant aux “Unités ou Systèmes de Transformation” (UTTE) et “Valorisation” (UTCE) pour terminer avec les “Systèmes productifs globaux du Territoire” (UTB) comprenant en filière les aspects existentiels (UTBES), sociaux (UTBSO) et économiques (UTBEC) hypothisés dans le “GRANDE ZONAZIONE: Grand zonage” (MORLAT R., 1996, CARBONNEAU A., 1996, TOUZARD J.M. 1998, CARBONNEAU A., CARGNELLO G., 1996, 1998, CARGNELLO G., 1994, 1995, 1996, 1998, 1999, 2001, -MILOTIC A., CARGNELLO G., PERSURIC G., 1999, PERSURIC G., STAYER M., CARGNELLO G., 2000, MILOTIC A., OPLANIC M., CARGNELLO G., PERSURIC G., 2000).

Vitiforestry as innovative heritage. Adaptive conservation of historical wine-growing landscapes as response to XXI century’s challenges.

Traditional agricultural and agro-pastoral systems (prior to industrial revolution) often have the characteristic of being multiple systems, in which multiple crops are hosted simultaneously on the same plot. currently research suggests to study more in depth the potential of multiple agricultural systems in order to detect those characteristics of multiple agrarian systems that could allow modern viticulture to adapt to the challenges posed by climate change: rising temperatures with impacts on the phenological cycle of the vine, resurgence of plant deseases, extreme soil washout phenomena and hail storms, among others.

Produce wines with no quantifiable phytosanitary residues – Impact of washing grapes?

Consumer expectations are increasingly shifting towards “residue-free wines.” However, from an analytical standpoint, “zero” does not exist. Laboratories often use the quantification limits of analysis methods to signify ‘zero.’ Improved techniques now allow for the quantification of levels that were previously undetectable. This is why we prefer to use the term “unquantifiable residue” rather than “absence of residues.”
