Union in the 1930s; he sent over factory designs, engineers, and skilled craftsmen, as well as tens of thousands of Ford tractors. By the 1940s Khrushchev was keenly interested in American agricultural innovations, especially on large-scale family-operated farms in the Midwest. In the 1950s he sent several delegations to visit farms and land grant colleges, looking at successful farms that utilized high-yielding seed varieties, very large and powerful tractors and other machines, all guided by modern management techniques. Especially after his visit to the United States in 1959, he was keenly aware of the need to emulate and even match American superiority and agricultural technology. Khrushchev became a hyper-enthusiastic crusader to grow corn (maize). He established a corn institute in Ukraine and ordered thousands of hectares to be planted with corn in the Virgin Lands. More than 1.5 million people went to Kazakhstan, the Volga Region, Siberia, and the Ural Mountains. In 1955, Khrushchev advocated an Iowa-style corn belt in the Soviet Union, and a Soviet delegation visited the U.S. state that summer. The delegation chief was approached by farmer and corn seed salesman Roswell Garst, who persuaded him to visit Garst's large farm. The Iowan visited the Soviet Union, where he became friends with Khrushchev, and Garst sold the USSR of seed corn. Garst warned the Soviets to grow the corn in the southern part of the country and to ensure there were sufficient stocks of fertilizer, insecticides, and herbicides. This, however, was not done, as Khrushchev sought to plant corn even in Siberia, and without the necessary chemicals. The corn experiment was not a great success, and he later complained that overenthusiastic officials, wanting to please him, had overplanted without laying the proper groundwork, and "as a result corn was discredited as a silage crop—and so was I". Khrushchev sought to abolish the Machine-Tractor Stations (MTS) which not only owned most large agricultural machines such as combines and tractors but also provided services such as plowing, and transfer their equipment and functions to the kolkhozes and sovkhozes (state farms). After a successful test involving MTS which served one large kolkhoz each, Khrushchev ordered a gradual transition—but then ordered that the change take place with great speed. Within three months, over half of the MTS facilities had been closed, and kolkhozes were being required to buy the equipment, with no discount given for older or dilapidated machines. MTS employees,
