The Roswell and Elizabeth Garst Farmstead Historic District is a farm in Guthrie County, Iowa, United States, near the city of Coon Rapids.

During the 1930s and 1940s, Garst played an active role in the conversion of old-style family farms to modern agribusiness.

Subsequently, Garst visited the Soviet Union to sell hybrid corn there and spread information about modern American farming methods.

[2] The comparison between a small Iowa farm community and a similar community in the Soviet Union must have been very striking indeed.After the conclusion of the visit, Llewellyn Thompson, then the U.S. ambassador to the Soviet Union, stated that the visit to the Garst farm was one of the most significant parts of Khrushchev's journey to the United States.
