Grapevine vigour is correlated with N-mineralization potential of soil from selected cool climate vineyards in Victoria, Australia

Abstract

Excess vigour has been a problem on fertile soils under high rainfall in many cool climate regions of Australia. High and low vigour blocks were selected in vineyards of the cool climate regions of King Valley, Yarra Valley and Mornington Peninsula, Victoria. Laboratory incubations were carried out on soil samples to measure their N-mineralization potential (N0). A strong relationship was observed between N0 and soil total N concentration across all sites. Vine internode length measured between flowering and fruit set could be used as a index of vine vigour and was well correlated with N0, but petiole N concentration was not a useful indicator of vigour at these sites. Sometimes high or low vigour may be due to other factors such soil water supply and soil depth, so that when interpreting a site’s potential for vigour all key soil and climatic variables should be considered.

Gamma-ray spectrometry In Burgundy vineyard for high resolution soil mapping

Aim: A soil mapping methodology based on gamma-ray spectrometry and soil sampling has been applied for the first time in Burgundy. The purpose of this innovative high-resolution mapping is to delimit soil areas, to define elementary units of soil for terroir characterization and vineyard management. The added value of this integrated approach is a continuous geophysical mapping of the soil with an investigation depth of 60cm.

Entomopathogenic nematodes application for controlling Lobesia botrana in grapevine and their impact on grapevine quality 

Entomopathogenic nematodes (EPN) are well-known biological control agents combined with specific adjuvants that now allow their use against aerial pests. Lobesia botrana (Lepidoptera: Tortricidae) is one of the major harmful pests detected in worldwide vineyards. Previous studies demonstrated that the EPNs Steinernema feltiae and S. carpocapsae could control L. botrana. The hypothesis was that the best combination of EPN-adjuvant/timing (season/temperatures) will support the use of EPN in the vineyard against L. botrana with no impact on the grape performance.
