Wheat exports of the U.S., Canada, and Argentina 1852-1988
From the mid-19th until the late 20th century, the United States was generally the largest wheat exporter in the Americas. In the early 1900s, however, it did lag behind the other two major wheat exporters in the Americas, Canada and Argentina, due to the post-WWI farming crisis in the U.S., the Great Depression (where exports even fell below 100,000 tons in some years), and the Second World War. Canada was generally the second largest producer in the Americas, and Argentina was third (although it did have the highest volume in some individual years).
