Well-planned irrigation is essential to improve vineyard quality and yield.
To see how well we were doing in terms of water efficiency, we ran a study from February 2009 to October 2010.
We used the following equipment:
• A conventional weather station to collect the main weather data and estimate crop evapotranspiration.
• An Eddy Covariance micro weather station to measure water vapour and carbon dioxide fluxes, with sensors to measure the available energy at soil surface.
• Three stations measuring soil moisture at different depths. All stations are self-powered and have an internet data transmission system using the GPRS protocol.
The data collected have enabled us to improve irrigation efficiency by using 30% less water.
