Mark Greenspan was an invited speaker at the ASEV Water Use Efficiency Symposium, held in Austin, Texas on June 24, 2014, which preceeded their annual conference. He presented on employing current research and technologies to help determine the water needs of the vineyard. Focusing on vine water status measurements and continuous soil moisture measurements, he told the audience that they probably can irrigate their vineyards less than they think they need to, but that measurements are essential to avoid over-stressing their vines. A wealth of other domestic and international experts were on hand at the symposium and an article on the symposium can be found here:
