The flaxseed situation in the United States has been unusual from 1909 to the present in that production has averaged slightly less than half of the consumption, although the acre income from flax in North Dakota, Minnesota, and South Dakota has been fairly consistently higher than that for spring wheat or oats. This relationship has held notwithstanding the all-too-general practice among farmers of sowing spring wheat and oats early on the best land and leaving the flax seeding until l ate on such land as may be left over.
