A bill to amend Sec. (b) (10) (a) and (c), Agricultural Adjustment Act of 1938 (7 U.S.C. 1281).

Amends the Agricultural Adjustment Act of 1938 to alter the formula (consisting of the amount of the domestic consumption of a commodity for the immediately preceding year, plus estimated exports for the year in question, plus an allowance for carry-over) for the determination of the "normal supply" of an agricultural commodity for any marketing year, on which acreage allotments are based. Increases the allowance for carry-over: (1) from 15 to 25 percent of the sum of domestic consumption and exports in the case of corn; (2) from 20 to 25 percent in the case of wheat; and (3) from 30 to 50 percent in the case of cotton.
