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.
