Influence of soil type on juice quality in a vineyard from DO Ca Rioja

Abstract

Soil plays an important role in wine quality, especially its water holding capacity because it affects the balance between vigour and grape yield. The aim of this work was to study the influence of different soil types on the must quality in a vineyard at DO Ca Rioja. The study was carried out during 2006 and 2007 in a vineyard of eight hectares, located in Oyón in Northern Spain. Four soil types were established according to topography and parent material: deposition (deeper than 110 cm and irregular distribution of organic matter in depth), calcareous red argillite (depth of 85-100 cm, with a heavy clay layer with reddish colour at 85-100 cm), calcareous lutite (depth of 50-100 cm) and finally sandstone (depth of 25-80 cm, and high sand content in depth). Grape samples were collected at 190 grapevines distributed through the whole vineyard for analysing , potential alcohol, total tartaric acid, pH, and K, and anthocyanins concentrations and polyphenols and colour indexes. The influence of soil type on juice quality varied according to the year. In 2006, in the soils with the lower water content (Sandstones) the potential alcohol was the highest (12.92 º), while in 2007, the Red argillite soil (greater water availability) got the greatest potential alcohol (13.72º). The highest acidity was obtained in Depression soil (5.51 g L-1) and was higher in 2007 (5.48 g L-1) than in 2006 (5.07 g L-1). Potassium juice concentration (3068 mg L-1) was higher in the Red argillite soil type due to its higher soil K content, and this caused also the higher pH (3.48) shown in this soil. The anthocyanins content, and polyphenols and colour indexes reached higher values in the Sandstone soil (803 mg L-1, 64 and 24 respectively).

The characterization of Vitis vinifera L cv. Cabernet sauvignon: the contribution of Ecklonia maxima seaweed extract

Biostimulants and biofertilizers are considered environmentally friendly and cost-effective alternatives to synthetic fertilizers, plant growth regulators and crop improvement products. Broadly, plant biostimulants are expected to improve nutrient use efficiency, tolerance to abiotic stress, quality traits and availability of nutrients in the soil or rhizosphere. Currently, seaweed extracts account for more than 33% of the total plant biostimulant market. Within this category, Ascophyllum nodosum (AN), is the most widely studied and applied in biostimulant formulations.

Cultivation of grapes Chardonnay in soils with management practices biodynamic and conventional

The cultivation of grapes, can be accomplished with the use of different systems and practices of agricultural management, the choice of the system to be followed in the vineyard, depends on the conditions of available resources, these being: natural, economic, social, cultural and territorial. As well, it is relevant to know the characteristics of the soil of the vineyard. In the last decade, has been recurrent use of agricultural practices which date back to milinares traditions, with the aim of promoting a recovery of soil and lead the management of cultivation with less damage to the ecosystem. The study here, aimed to quantify the environmental impacts caused in the use of nutrients in conventional tillage and of grapes in the biodynamic agricultural properties in the state of Rio Grande do Sul- Brazil.

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.
