Industrial output vs agricultural output during the Great Depression

[Red-Right]

During the Great Depression industrial prices dropped by one third and the industrial output dropped by one half. On the other hand agricultural prices dropped by one half and the agricultural output remained constant(correct me if I am wrong). Why was that?

In the United States there was a major initiative by the FDR government to destroy surplus crops. Throughout the 1920s there was a price glut in crops due to 'overproduction' as a result of increasing industrialization in agriculture.
