Characterization and modelling of water flow on vineyard soil. Effect of compaction and grass cover

Abstract

In the Burgundy vineyard, frequent tractor traffic and management of inter-rows alternating grass cover and chemical weed-control lead to structural soil contrast between row and inter-row. The aim of this study was to characterize and model water flow in relation with topsoil structure modifications induced by these practices. Void ratio of the different soil volumes were determined using bulk density measurements. Water flow was measured with tensiometers under two simulated rainfalls. Hydraulics properties of soil volumes defined at the profile level was characterized by water retention curve and infiltrometer measurements. Hydrus 2D software was used for 2D modelling of water flow on a transect perpendicular to the rows. Compaction of the 25 first centimetres of inter-row topsoil was observed in the two types of interrows. It led to a void ratio reduction of 37% and a reduction of the saturated hydraulic conductivity generating less infiltration than in rows. Grass-covered inter-rows were characterized by a macroporous mat root at the soil surface (0-3 cm) in the upper part of the underlying compacted volume. More infiltration was measured in inter-rows with grass cover than in chemically weed-controlled inter-rows. Modelling fairly reproduced contrast of water flow contrast in relation with soil structure for the first 25 centimetres. However, modelling was unable to reproduce flow in volume likely to be affected by preferential flow. Between 25 and 70 centimetres depth, soils containing numerous vine roots would be the seat of preferential flow pathways distributing water laterally from rows to inter-rows. Effectiveness of preferential pathways would increase with soil moisture and rainfall intensity.

INCREASING PINOT NOIR COLOUR DENSITY THROUGH SEQUENTIAL INOCULATION OF FLOCCULENT COMMERCIAL WINE YEAST SPECIES

Vitis vinifera L. cv. Pinot noir can be challenging to manage in the winery as its thin skins require careful handling to ensure sufficient extraction of wine colour to promote colour stability during ageing.1 Literature has shown that fermentation with flocculent yeasts can increase red wine colour density.2 As consumers prefer greater colour density in red wines,3 the development of tools to increase colour density would be useful for the wine industry. This research explored the impact of interspecies sequential inoculation and co-flocculation of commercial yeast on Pinot noir wine colour.

The effect of pedoclimatic conditions on the yeast assimilable nitrogen concentration on white cv. Doral in Switzerland

Aims: Agroscope investigated the efficiency of nitrogen fertilization via foliar urea application at veraison with the aim of raising the YAN (yeast assimilable nitrogen) content in the musts. The observations were conducted on the white grapevine cultivar Doral (Chasselas x Chardonnay) in several pedoclimatic conditions of the Leman wine region, Switzerland, in the years 2012 and 2013. Knowing that the YAN in must plays a key role in wine quality, the aim was finding the main parameters affecting the final YAN level in order to better control them.
