Use of the soils information system for detailed vineyard soil surveys and as a component of precision viticulture

Abstract

Vineyard soil surveys can be costly and time consuming. The Soils Information System (SIS) provides a set of tools to do a quick evaluation of soil physical properties in the vineyard. First, a system equipped with GPS and EM38 equipment, provides a very precise DEM and a soil electrical conductivity map. Specific sampling points are located for a tractor-mounted geotechnical probe to make soil physical measurements. Sensor readings are used to make precise estimations of soil texture, compaction, moisture and resistivity in the field. The probe reaches a depth of 1.2 to 1.5 meters. The data obtained are used to construct thematic maps, such as soil texture, soil compaction, and soil moisture availability maps. Finally, soil cores can be collected and sent to the laboratory to validate the SIS measurements and perform further analyses when required. This system has been used in vineyards located in different terroir regions of California, France and Spain. Results demonstrated a more precise delineation of soil map units than traditional survey methods using pits and augers. This approach allowed a more precise mapping of soil depth to the underlying rock layers. It also provided the information necessary to design an irrigation system in a newly planted vineyard. In summary, SIS provides a rapid and effective approach to precision mapping of terroir components and will have broad applications for precision viticulture.

Investigation of the effect of gelatine and egg albumin fining and cross-flow microfiltration on the phenolic composition of Pinotage red wine

Results indicated that cross-flow microfiltration removed similarly to fining treatments the most astringent tannins, but cross-flow microfiltration also removed up to 14 % more colour. RP-HPLC and spectrophotometric results showed that egg albumin is a softer fining treatment compared to gelatine and cross-flow microfiltration.

Quantitative and qualitative changes in terpenes during enzymatic maceration and fermentation in wine production: insights from Polish grape varieties

The production of fermented alcoholic beverages involves numerous processes in which microorganisms and enzymes convert components derived from the raw material into a wide range of compounds that affect the sensory characteristics of the resulting product. It is estimated that there may be as many as 800 to 1,000 such compounds in wine. These compounds belong to different chemical groups such as esters, alcohols, carboxylic acids, carbonyl compounds, polyphenols, sugars and many others.

Genome wide association mapping of phenology related traits in Vitis vinifera L

Climate change, with rise in temperatures, is leading to an advance in the dates of phenological stages, with a loss in quality of the grape final product. Therefore, the understanding of the genetic determinants driving the phenological stages of flowering, veraison and the interval between them, represents a target for the development of grapevine’s cultivar adapted to the changing environment.
Here we conducted a GWA study to identify SNPs significantly associated to flowering time, veraison time and to the interval among them. A germplasm collection (CREA-VE in Susegana, Treviso, Italy) including 649 grapevine’s cultivar representing 365 unique genotypes was considered.
