The Roswell and Elizabeth Garst Farmstead Historic District is a farm in Guthrie County, Iowa, United States, near the city of Coon Rapids. It is significant as the home of farmer and hybrid corn populizer Roswell Garst. During the 1930s and 1940s, Garst played an active role in the conversion of old-style family farms to modern agribusiness. He was a key marketer of hybrid seed corn, which greatly increased corn yields per acre. Further, he espoused the use of nitrogen and other chemical fertilizers to renew soil so that fields need not be left fallow in order for the soil to replenish, allowing farmers to grow more acres of corn. Additionally, he embraced the use of cellulose from corncobs left after processing seed corn as cattle feed. (82 pages, with exterior and interior photos) Read more on Wikipedia
