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

L’agricoltura dei territori costituenti l’antica “Terra di Lavoro”, territorio che oggi è compreso nella provincia di Caserta ed in parte di quelle di Frosinone e Latina, ha subito a partire dal 1970

GEOSPHERA s. r. l. e TERR.A.IN. CNS, forti della grande esperienza dei loro collaboratori nell’ambito delle scienze naturali, della geologia, della geofisica e dell’informatica, garantiscono risposte innovative alle problematiche della moderna agricoltura rivolgendosi direttamente ai viticoltori, ai commercianti vinicoli ed ai liberi professionisti.

One of the major problems affecting the viticulture sector is the quantity of plant protection products (especially copper) used to control the main foliar diseases of the vine. The Life Green Grapes project enter in the production context with the aim of reducing the use of fungicides throughout

This study focuses on investigating the effects of climate change on the plant physiology and berries of Vitis vinifera cv “Monastrell” in a commercial vineyard managed organically in Southeastern Spain (Jumilla, Murcia). For this purpose, open top chambers and rainout shelters were employed to simulate warming (~2-7 ºC, W) and rainfall reduction (~30%, RR) respectively. Additionally, a combination of both treatments (W+RR) was employed. Vines without either top chambers or rainout shelters were considered as control (C). The experiment was established in February of 2023. Predawn leaf water potential (measured using a pressure chamber), stomatal conductance (assessed with a porometer at mid-morning) and leaf chlorophyll and flavonoid content (measured using the Dualex® leaf clip sensor) were analyzed at veraison (5 months after the installation of structures).

This study explored the responses of Chardonnay and Sauvignon blanc grapevine cultivars to water deficit across four years, uncovering their shared patterns and distinctive coping mechanisms. The research was conducted in a commercial vineyard located in Isla de Maipo, Chile. Various characterization approaches were employed including plant water potentials (), gas exchange measurements, shoot vulnerability curves, productivity assessments, and leaf cell water relations. Linear mixed models and sensitivity analyses were performed using various statistical methods to evaluate cultivar responses to water deficit. As the water deficit progressed, both cultivars displayed a parallel reduction in stomatal conductance, leaf turgor, and increased shoot embolism.
