By 1890, advancements in mechanization, seed quality, irrigation, and sustainable practices had spurred a farming boom. Columbia Basin irrigation and the development of synthetic fertilizers, as well as Cooperative Extension efforts and impressive work by agricultural researchers greatly boosted regional production. Harvest Heritage explores the people, history, and major influences that shaped and transformed the Pacific Northwest's flourishing agrarian economy.
