The Washington State legislature established the Irrigation Branch Experimental Station, in 1917 because of such challenges; however, there was no funding until 1919. Later renamed the Irrigated Agriculture Research and Extension Center (IAREC), it was to assist the state’s then fledging agriculture industry. The first researchers who came to work in this arid environment faced many challenges. The soil lacked such basic nutrients as zinc and nitrogen. Daylong dust storms blanketed crops and topsoil. Weeds not only aggressively competed with newly planted crops, but choked irrigation canals that delivered the region’s most vital resource – water.
Today, nearly 100 years later, cooperative research among WSU, USDA-ARS, and WSDA conducted at Prosser IAREC is still pioneering unique and innovative developments in irrigated agriculture. Farmers have taken advantage of the results of this work and transformed the arid basin of the southeastern part of Washington State into one of the most fertile and productive regions in the world. The state’s economy benefits from more than $3,000,000,000 of annual revenue generated by more than 60 irrigated crops.
