Expanding outward from Greeley to all of northern Colorado, Cattle Beet Capital shows how the beet sugar industry came to dominate the region in the early twentieth century through a reciprocal relationship with its growers that supported a healthy and sustainable agriculture while simultaneously exploiting tens of thousands of migrant laborers. Michael Weeks shows how the state provided much of the scaffolding for the industry in the form of tariffs and research that synchronized with the agendas of industry and large farmers. The transformations that led to commercial feedlots began during the 1930s as farmers replaced crop rotations and seasonal livestock operations with densely packed cattle pens, mono-cropped corn, and the products pouring out of agro-industrial labs and factories. Using the lens of the northern Colorado region, Cattle Beet Capital illuminates the historical processes that made our modern food systems.
