Whenever in any county or other area the Secretary finds that the actual production of corn plus the amount of corn stored under seal in such county or other area is less than the normal production of the marketing percentage of the farm acreage allotments in such county or other area, the Secretary shall terminate farm marketing quotas for corn in such county or other area.

Whenever, upon any farm, the actual production of the acreage of corn is less than the normal production of the marketing percentage of the farm acreage allotment, there may be marketed, without penalty, from such farm an amount of corn from the corn stored under seal pursuant to section 1324 of this title which, together with the actual production of the then current crop, will equal the normal production of the marketing percentage of the farm acreage allotment.

Whenever, in any marketing year, marketing quotas are not in effect with respect to the crop of corn produced in the calendar year in which such marketing year begins, all marketing quotas applicable to previous crops of corn shall be terminated.
