REGAVID a decision tool to deficit irrigation in a temperate climate (DO Monterrei – Spain)

Abstract

In temperate climates, such as in the North of Spain, the use of irrigation in the vineyard has not been required, due to the usual rainfall from June to August. In some large vineyards, irrigation management has been carried out, based on occasional support irrigation, or for the application of nutrients (fertigation). Currently it is necessary to implement decision support models to manage irrigation water in real time and avoid misuse of a scarce resource. Moreover, quality standards must be achieved, as in the previous rainfed viticulture. The develop model, REGAVID, linked to an Operational Group in Galicia – Spain, include the characterization of soil physical properties, plant canopy, meteorological data, as well as the irrigation system. The calibration of crop coefficients has been carried out in a commercial vineyard of the DO Monterrei (Spain), in 2022, taking into account the crop evapotranspiration throughout the vegetative-productive cycle. Based on the measurements of soil water (potential and content), and the weather forecast for a week ahead, the irrigation starts parameters have been programmed, as well as the weekly irrigation dose.

The use of continuous measurement sensors, Watermark, at different depths allows knowing the dynamics of water in the soil and establishing thresholds to manage the irrigation. The irrigation management support system allows defining a different deficit irrigation strategy depending on vineyard stage and the season.

In conclusion, flexible irrigation management tools are key for irrigation management in temperate climates, even more so with mostly sandy and fast-draining soils.

The environmental footprint of selected vineyard management practices: A case study from Logroño (La Rioja) Spain

Viticulture is globally important for socioeconomic and environmental reasons. The EU is globally leading grape and wine production, and Spain is among the top grape and wine producers. As climate change affects viticulture, mitigation and adaptation are crucial for protecting grape production. In this research work, data on viticultural management practices such as soil cultivation, irrigation, energy, machinery, plant protection and the use of fertilizers from vineyards located in Logroño (La Rioja) have been obtained.

Bioprotection of grape must by Metschnikowia sp.: genericity and mechanism

The market trend heads to food products with less chemical inputs, including in oenology. During the winemaking process, sulfites are commonly use to avoid microbiological contamination and stabilization of the wine thanks to its antimicrobial and antioxidant activities. Nevertheless, this use is not without consequences on human health and environment, leading for example to allergic reaction and pollution. A biological alternative to these sulfites has emerges: the bioprotection.

Preliminary results of water status and metabolite content of three new crossbreed winegrape genotypes

This study presents the preliminary results obtained in 2022, of the evaluation of three new crossbreed winegrape genotypes and their parental varieties, grown under controlled irrigation (60% ETc) and rainfed conditions in a wine-growing area with scarcity of water and high temperatures (Murcia, southeast Spain). The genotypes MC16 and MC80 were obtained from crosses between the varieties ‘Monastrell’ and ‘Cabernet Sauvignon’, and MS104 from crosses between ‘Monastrell’ and ‘Syrah’ [1]. The objective of this study was to analyse the physiological response and vegetative development of the 6 genotypes under the two irrigation conditions, and to study their effect on the content of soluble sugars and chlorophyll in the leaf.

Possible methods of adaptation to the effects of climate change in the Tokaj Wine Region 

Viticulture’s adaptation to the harmful effects of climate change is globally the biggest challenge of the near future. Short, extremely intensive rainfalls and longer periods of drought are getting more frequent in the Tokaj Wine Region, where the majority of the vineyards are cultivated on steep slopes. Hence, erosion has high risk, especially when combined with the loess-based soils on about ten percent of the region. The environmentally beneficial cover crop and mulch usage can effectively reduce the risk of erosion, according to research done by the Tokaj Wine Region Research Institute of Viticulture and Oenology.
