Vineyard Soils

Vineyard-living microbiota affect grapevine health and adaptation to changing environments and determine the biological quality of soils that strongly influence wine quality. However, their abundance and interactions may be affected by vineyard management. The present study was conducted to assess whether the vineyard soil microbiome was altered by the use of biostimulants (arbuscular mycorrhizal fungi (AMF) inoculation vs. non-inoculated) and/or irrigation management (fully irrigated vs. half irrigated). Bacterial and fungal communities in vineyard soils were shaped by both time course and soil management (i.e., the use of biostimulants and irrigation). Regarding alpha diversity, fungal communities were more responsive to treatments, whereas changes in beta diversity were mainly recorded in the bacterial communities. Edaphic factors rarely influence bacterial and fungal communities. Microbial network analyses suggested that the bacterial associations were weaker than the fungal ones under half irrigation and that the inoculation with AMF led to the increase in positive associations between vineyard-soil-living microbes. Altogether, the results highlight the need for more studies on the effect of management practices, especially the addition of AMF on cropping systems, to fully understand the factors that drive their variability, strengthen beneficial microbial networks, and achieve better soil quality, which will improve crop performance.

The grape production and grape and wine quality of Shiraz vines, grown either on their own roots or on 6 rootstocks that have varying resistance to nematodes, were compared. Vines on the rootstocks Ramsey and Dog Ridge outyielded ungrafted vines by 46 and 48%, respectively, principally because of increased vegetative growth and hence retention of more nodes at pruning. Ramsey rootstock gave a greater grape yield per shoot. The ability of Dog Ridge stocks to produce yields as high as those of Ramsey highlights the importance of adequate pruning levels to enable the full potential of rootstocks to be determined. Vines on the rootstock Dog Ridge produced wines with higher pH values than wines from ungrafted control vines. Nematode counts suggested that the Vitus champini stocks have good tolerance to both rootknot and root lesion nematodes.

Nowadays, agronomic practices are evolving towards a “Sustainable Agriculture” using environmentally friendly systems. Modern viticulture aims to reduce inputs without reducing grape yield and wine quality. As a result of pruning, vine-shoots are generated as the waste of the vineyard. However their aqueous extracts have shown to have significant contents of bioactive compounds and, therefore, biostimulant activity. The foliar applications of vine-shoot extracts onto white grapevine variety caused a reduction in the sugar content, further an effect on the grape reaction product (trans-GRP) content was observed.

Traminer is a well-known grapevine cultivar. It is thought to originate from Tramin, Italy, wherefrom it has been introduced to many European countries (France, Switzerland, Austria, Germany). Researches included two Traminer cultivar forms: White Traminer and Red Traminer. Examinations were carried out in a collection vineyard of the Viticulture and Wine Production Center of Nis. The collection vineyard was planted in 1995, with planting space of 3 x 1.2 m. Examinations took three years (2004-2006) and encompassed phenological observations, fertility, vegetative potential of a vine, resistance to Botrytis cinerea and wine quality. A detailed ampelographic description of two Traminer cultivar forms was also provided according to O.I.V. descriptors. The purpose of this paper is to determine growth, fertility, yield, and grape and wine quality of the examined Traminer cultivar forms in the viticultural subregion of Nis. According to the results obtained, the examined forms could be successfully grown in this region. Average grape yield varied depending on conditions of the particular year. White Traminer recorded higher yield, while Red Traminer recorded better quality. In addition, the best vines have been selected within the forms, and they will be used in further studies and multiplication.

Abstract Background: Vineyard-living microbiota play a relevant role in supporting grapevine health and adaptation to changing environments and determining the biological quality of soils that strongly influence the wine quality and characteristics. However, management practices may shape the abundance and interactions of bacteria and fungi in vineyard soils. We conducted this experiment to assess whether the vineyard soil microbiome was altered by different management practices with the use of biostimulants (arbuscular mycorrhizal fungi (AMF) inoculation vs. non-inoculated) and/or irrigation management (full irrigated vs. half irrigated). Results: Bacterial and fungal communities in vineyard soils were shaped by both time course and soil management (i.e. use of biostimulants or irrigation). Regarding alpha diversity, fungal communities were more responsive to treatments whereas changes on beta diversity were mainly recorded in the bacterial communities. Edaphic factors rarely influenced bacterial and fungal communities. Microbial network analyses suggested that the bacterial associations were weaker than the fungal ones under half irrigation and that the inoculation with AMF led to the increase of positive associations between vineyard soil-living microbes. Conclusion: Our results indicated different sensibilities within microbial communities living in vineyards, as well as, how they changed during the season, and in response to management practices. Moreover, results highlighted the need of more studies leading with the effect of management practices, especially the addition of AMF, to cropping systems to fully understand the factors that drive their variability, strengthen beneficial microbial networks and achieved a better soil quality that improves crop performance.

Aims: Soil acidity decreases soil fertility and grapevine growth. Aluminum toxicity has been recognized as one of the most common causes of reduced grape yields in acid vineyard soils. The main aim of this study was to evaluate the effect of two liming materials, i.e. dolomitic lime and sugar foam, on a vineyard cultivated in an acid soil.Methods and results: The effects were studied in two soil layers (0-30 and 30-60 cm), as well as on leaf nutrient contents, grape yield, and must and wine quality properties, in a vineyard dedicated to Vitis vinifera L. cv. Mencía cultivation. The data management and analysis were carried out using ANOVA.Conclusion: Sugar foam was more efficient than dolomitic limestone as liming material since it induced the highest decrease in soil acidity properties at the same calcium carbonate equivalent dose. Effects of liming on leaf nutrient contents, grape yield, and must and wine quality properties were barely observed.Significance and impact of the study: Until recently, little was known about the effects of liming on both vine nutritional status and must/wine quality properties. Thus, this research fills an important knowledge gap.

The first edition of Understanding Vineyard Soils has been praised for its comprehensive coverage of soil topics relevant to viticulture. However, the industry is dynamic--new developments are occurring, especially with respect to measuring soil variability, managing soil water, possible effects of climate change, rootstock breeding and selection, monitoring sustainability, and improving grape quality and the "typicity" of wines. All this is embodied in an increased focus on the terroir or "sense of place" of vineyard sites, with greater emphasis being placed on wine quality relative to quantity in an increasingly competitive world market. The promotion of organic and biodynamic practices has raised a general awareness of "soil health", which is often associated with a soil's biology, but which to be properly assessed must be focused on a soil's physical, chemical, and biological properties. This edition of White's influential book presents the latest updates on these and other developments in soil management in vineyards. With a minimum of scientific jargon, Understanding Vineyard Soils explains the interaction between soils on a variety of parent materials around the world and grapevine growth and wine typicity. The essential chemical and physical processes involving nutrients, water, oxygen and carbon dioxide, moderated by the activities of soil organisms, are discussed. Methods are proposed for alleviating adverse conditions such as soil acidity, sodicity, compaction, poor drainage, and salinity. The pros and cons of organic viticulture are debated, as are the possible effects of climate change. The author explains how sustainable wine production requires winegrowers to take care of the soil and minimize their impact on the environment. This book is a practical guide for winegrowers and the lay reader who is seeking general information about soils, but who may also wish to pursue in more depth the influence of different soil types on vine performance and wine character.
