The World’s Largest Irrigated Agriculture Center

The Washington State University, Irrigated Agriculture Research and Extension Center (WSU Prosser IAREC) is the focal point for the University, the U.S. Department of Agriculture – Agricultural Research Service (USDA-ARS), and the Washington State Department of Agriculture (WSDA) research, extension, and plant certification programs that address the concerns of irrigated agriculture.

An estimated two-thirds of the agricultural production in the state comes from irrigated land, making such research of vital interest to Washington’s economy, both for intrastate distribution and exportation.
