Last year Iowa farmers grew 40,000 acres of flax, the most in many years. They will probably grow a still larger acreage in 1940 because of the yield and price of the 1939 crop, and as in 1939, they may grow and harvest flax under the 1940 AAA program without having it count as a soil-depleting crop providing it is used as a nurse crop for clover, alfalfa or grass seeding.
