Spanish scientist improves vineyard irrigation
April 27, 2011

PROSSER, Wash. – In much of Europe, it is illegal to irrigate wine grapes after veraison – the change of color indicating ripening – for fear of diluting brix, or sugar content. But recent research is calling into question this taboo, especially for semiarid regions like eastern Washington – and Spain.


In fact, a visiting scientist from Spain, Pascual Romero, is working for a year at WSU’s Irrigated Agriculture Research and Extension Center at Prosser to better understand irrigation management in vineyards.

Irrigation study shows ways to save water, energy and money


SKAGIT COUNTY – A study of big gun vs. boom irrigation systems in Skagit County may help growers save money as well as water.


In summer 2007, Don McMoran, agriculture and natural resources educator at WSU Extension Skagit County, and Troy Peters, extension irrigation specialist at WSU Prosser, teamed up to compare the efficiency and uniformity of big gun and boom irrigation systems.


“The manufacturers said that boom systems were 85 percent efficient … » More …

Drought conditions bring tough choices for growers
April 26, 2005

Drought conditions in Washington, especially irrigation rationing in the Yakima Valley, are leading to hard choices for area growers, according to two Washington State University Extension educators.”We’re already seeing some crop shifting,” said Bob Stevens, extension soil scientist and interim director of WSU’s Prosser Irrigated Agriculture Research and Extension Center. “Some orchards already are being removed. Those growers may have been considering that option for awhile, but the lack of water is leading them to do it now.”Gov. Christine Gregoire last month authorized a statewide drought emergency because of low snow pack statewide, and earlier this month theBureau of Reclamation imposed rationing at 34 percent … » More …
