“Compost Application in the Vineyard: Effects on Soil Nutrition and Compaction”

Abstract

The mechanization of pruning and harvesting in vineyards has increased the risk of soil compaction. To reclaim soil properties or avoid this degradation process, it is crucial to properly manage the soil organic matter, and the application of compost derived from the vines themselves is a strategy to achieve this. The objective of this study was to evaluate the properties of soil treated with different doses of compost applied both on the vine row and the inter rows of a Vitis vinifera crop.

The experiment was established in May 2020, in three fields with clay contents ranging between 17-36%, with 7 treatments corresponding to compost application rates (0, 4, 10, 20 tons ha-1) and position (inter and intra row). Measurements of soil physical and chemical properties were taken, as well as variables related to the plants.

It was observed that the inter rows had a more deteriorated structural condition compared to the vine rows, especially at surface. However, the increase in compost doses led to a significant decrease in penetration resistance and a notable increase in coarse porosity, especially in soil with more than 20% clay. No evident changes were found in bulk density and soil aggregate stability. An increase in macronutrients (N, P, K) was detected because of compost application, although the effects varied according to soil type.

The treatments did not affect the physiological and productive variables of the plants, although an increase in some foliar nutrients and an improvement in the Ravaz index were observed with compost applications, indicating a more balanced proportion between grape production, and pruning mass. In conclusion, compost application has positive effects on soil properties, especially in the area between rows, by providing nutrients that promote the vegetative and productive balance of the vines, thereby contributing to sustainable production.

The colour pattern of flower arrangements influence wine tasters’ sensory description

The arrangements of flowers and wine counterparts are inextricably linked. Whether a fundamental aspect of tablescaping or acolytes to broader entertainment rituals, they have an entangled history since ancient times. The aim of this contribution is to verify the influence of visually delicate and robust flower arrangements on individual description of wines. Changes in the sensory description of wines were investigated during subjects’ (thirty-two participants) exposure to three different conditions: the presence of delicate, robust, or totally absent flower arrangements. In each condition, the same two wines were blind tasted: a wine previously defined as delicate – a Pinot Noir from Australia, and a wine known for its robust character – a Tannat from Uruguay.

Evaluation of phenology, agronomic and oenological quality in minority wine varieties in Madrid as a strategy for adaptation to climate change

The main phenological stages (budburst, flowering, veraison, and ripeness) and the fruit composition of 34 Spanish minority varieties were studied to determine their cultivation potential and help winegrowers adapt their production systems to climate change conditions. In total, 4 control cultivars, and 30 minority varieties from central Spain were studied during a period of 3 campaigns, in the ampelographic collection “El Encín”, in Alcalá de Henares, Madrid. Agronomic and oenological characteristics such as yield, and total soluble solids concentration have been monitored.

Combined use of leaf removal and natural shading to delay grape ripening in Manto negro (Vitis vinifera L.) under deficit irrigation 

The increasingly frequent heat waves during grape ripening pose challenges for premium wine grape production. This makes the development of irrigation and canopy management techniques of great importance to maximize yield and grape quality. A field experiment was carried out during 2021 and 2022 using Manto negro wine grapes to study the effect of two irrigation strategies and different light exposure levels on grape quality.

Do wine sulphites affect gut microbiota? An in vitro study of their digestion in the gastrointestinal tract

“Sulphites” and mainly sulphur dioxide (SO2) is by far the most widely used additive (E-220/INS 220) in winemaking and likely the most difficult to replace. The well-known antioxidant, antioxidasic and antimicrobial properties of SO2 make this molecule a practically essential tool, not only in winemaking, but also in the production of other food products. The current trend in winemaking is the reduction of this unfriendly additive due to its negative effects on health and environmental. In particular, it could cause headaches and intolerance/allergic reactions in sensitive individuals. Wine is considered one of the major contributors of exposure of SO2 in the adult population, when this beverage is included in the diet.
