AWRI Webinar: Greenhouse gas emissions in vineyards
Date(s) - 10 Dec 2013
11:30 AM - 12:30 PM
It is widely accepted that agriculture is both a source and a sink for greenhouse gas (GHG) emissions. Nitrous oxide (N2O) is a powerful GHG with approximately 300 times the greenhouse potential of carbon dioxide and its main source is nitrogen fertiliser. In 2012 N2O emissions were measured using static chambers at five Australian commercial vineyards with a diverse range of climates, soil types and management practices. Emissions were measured throughout the year to coincide with significant rainfall and management events to establish baseline data under typical viticultural production systems. This work will establish typical N2O emissions for several Australian winegrape growing regions and enable the identification of practices which can be adopted by vineyard managers to decrease N2O emissions from vineyards. It also aims to advance the dialogue across the grape and wine sector around vineyard sustainability.
