A 4D high resolution vineyard soil assessment for soil-hydrological interpretation in combination with automated data analysis and visualization to manage site-specific grape and wine quality

Abstract

A Visual Information eNvironment for Effective agricultural management and Sustainability (VINES) is under development, which can provide significant competitive advantages to winegrowers by sustaining their appellation-specific grape and wine qualities and yields while measurably conserving water resources. The system has been designed to validate, refine, and improve the Automatic Landform Inference Mapping (ALIM) soil modeling/ sampling method, and to define the key components for perennial crop production, in general, and wine grapes in particular.

The feasibility of this novel technology has been validated through analysis of data collected to date through sensor deployment in West Coast vineyards and the development of highly resolved 4D soil maps that can visualize vine water availability. A comparison of predicted map-based water flow at several depths and locations vs. in-field sensor sampled values was conducted.

The accuracy of predicted soil characteristics across vineyard blocks at several locations has been validated based on physical and chemical analyses and statistical comparisons. The first completed real-time spatial soil functional maps have been used to design visual analytics to create an effective decision-making environment applicable in commercial vineyards.

Working directly with vineyard managers and winemakers, this integrated research and extension project has collaboratively developed an interactive, user-driven decision making environment that harnesses visual analytics to organize all the inputs from deployed soil sensors, high-resolution spatial soil function and water dynamic responses, while integrating all available historic and current data flows. VINES is designed to integrate future soil, plant, viticulture, and enological models into its decision support system to help respond to changing climatic and especially to drought conditions, and to improve general vineyard management, harvest scheduling, and long-term sustainability and life-cycle decisions.

Vintel: a single decision support system for irrigation, fertilization and disease management of grapevine

Vine growers face an increasing number of decisions, both tactical and strategic, in a context where available data and constraints are on the rise, such as resources, societal, environmental, climatic, and economic factors. This has led to a growing supply of decision support systems (DSS) and softwares to manage vineyards. Facing this new complexity, growers must now consider several options: giving up the use of DSS, using systems that are compatible with each other but may limit their options, or using a single system that may be too complex to use effectively. In this context, itk has expanded its Vintel® tool, which was originally designed for grapevine water status management (irrigation, inter-row, cover-crop, etc.), to include fertilization and disease management.

Prove preliminari dl caratterizzazione del vino gutturnio dei colli piacentini

The “GuIturnio dei Colli Piacentini” V.Q.PR.D. results from the vinification of Barbera (55-70%) and Bonarda (30-40%) cultivars, grown in the hilly area of the Piacenza district, identified by the DM 31-07-93 art. 3.
The present work concerns the “zonation” of this area, constituted by 3 valleys Tidone (A), Nure (B) and Arda (C )

Efficacy of tannins of different botanical origin as partial or total substitute of SO2 to preserve a Cortese white wine during storage in cellar

While SO2 is one of the oldest and widest additive used in enology for its well-known antioxidant, anti-laccase and antimicrobial properties, it can cause health problems in some individuals.

Autochthonous yeasts: a microbiological tool to exalt the quality of the apulian sparkling wine

The selection, characterization, and recruitment of autochthonous yeast strains to drive the alcoholic fermentation process is a highly researched practice because it allows the differentiation of the organoleptic properties of wines, assuring process standardization, reducing fermentation times and improving the quality and safety of the final products [1, 2]. Sparkling wines are “special wines” obtained by secondary fermentation of the base wine. ​In the traditional method (Champenoise method), the re-fermentation takes place in the bottle after the addition to the base wine of the so-called tirage solution. This step, also known as prise de mousse, is followed by an aging period characterized by the release of compounds from the yeast cells that affect the organoleptic properties of the final product. The use of autochthonous yeasts as starter cultures for secondary fermentation is one of the recent innovations proposed to enhance and differentiate these wines’ sensory quality [3,4]. Apulia is the second Italian wine-producing region, and its productive chain is now going through a qualitative evolution by implementing the employment of innovative approaches to exalt the peculiar properties of regional wines.

Training vineyards resilience to environmental variations by managing vine water use

The challenges of the century for viticulture relate to coping with climate change and the loss of biodiversity in a downturning socio-economic context. Now more than ever, the vine and wine industry needs to be resilient to maintain and ensure a future for its heritage. An innovation of capital importance, in line with recently published research, deals with developing new methods of training our inherited and newly planted vineyards to better withstand environmental variations such as drought and heatwaves but also unevenly distributed rains and temperatures.
