7 U.S.C. § 1339

(a) Penalties: computation, lien, joint and several liability and interest; exceptions: nonsurplus supply crops, substantial impairment, and nonproduction of wheat; diverted acreage: amount, annual identity, and grazing; crops available for marketing (1) During any year in which marketing quotas for wheat are in effect, the producers on any farm (except a new farm receiving an allotment from the reserve for new farms) on which any crop is produced on acreage required to be diverted from the production of wheat shall be subject to a penalty on such crop, in addition to any marketing quota penalty applicable to such crops, as provided in this subsection unless (1) the crop is designated by the Secretary as one which is not in surplus supply and will not be in surplus supply if it is permitted to be grown on the diverted acreage, or as one the production of which will not substantially impair the purpose of the requirements of this section, or (2) no wheat is produced on the farm, and the producers have not filed an agreement or a statement of intention to participate in the payment program formulated pursuant to subsection (b) of this section. The acreage required to be diverted from the production of wheat on the farm shall be an acreage of cropland equal to the number of acres determined by multiplying the farm acreage allotment by the diversion factor determined by dividing the number of acres by which the national acreage allotment (less an acreage equal to the increased acreage allotted for 1966 pursuant to section 1335 of this title ) is reduced below fifty-five million acres by the number of acres in the national acreage allotment (less an acreage equal to the increased acreage allotted for 1966 pursuant to section 1335 of this title ). The actual production of any crop subject to penalty under this subsection shall be regarded as available for marketing and the penalty on such crop shall be computed on the actual acreage of such crop at the rate of 65 per centum of the parity price per bushel of wheat as of May 1 of the calendar year in which such crop is harvested, multiplied by the normal yield of wheat per acre established for the farm. Until the producers on any farm pay the penalty on such crop, the entire crop of wheat produced on the farm and any subsequent crop of wheat subject to marketing quotas in which the producer has an interest shall be subject to a lien in favor of the United States for the amount of the penalty. Each producer having an interest in the crop or crops on acreage diverted or required to be diverted from the production of wheat shall be jointly and severally liable for the entire amount of the penalty. The persons liable for the payment or collection of the penalty under this section shall be liable also for interest thereon at the rate of 6 per centum per annum from the date the penalty becomes due until the date of payment of such penalty. (2) The Secretary may require that the acreage on any farm diverted from the production of wheat be land which was diverted from the production of wheat in the previous year, to the extent he determines that such requirement is necessary to effectuate the purposes of this part. (3) The Secretary may permit the diverted acreage to be grazed in accordance with regulations prescribed by the Secretary. (b) Payment program for 1964 through 1970 crops; terms and conditions; amount; additional diverted acreage; conservation and soil-conserving uses; adjustment; knowledge of exceeding acreage allotment; acreage allotment not exceeded by delivery to Secretary of farm marketing excess or storage in accordance with regulations to avoid or postpone payment of penalty or by farms exempt from marketing quota; new farms ineligible for payments; sharing and medium of payments The Secretary is authorized to formulate and carry out a program with respect to the crops of wheat planted for harvest in the calendar years 1964 through 1970 under which, subject to such terms and conditions as he determines are desirable to effectuate the purposes of this section, payments may be made in amounts not in excess of 50 per centum of the estimated basic county support rate for wheat not accompanied by marketing certificates on the normal production of the acreage diverted taking into account the income objectives of the chapter, determined by the Secretary to be fair and reasonable with respect to acreage diverted pursuant to subsection (a) of this section. Any producer who complies with his 1964 farm acreage allotment for wheat and with the other requirements of the program shall be eligible to receive payments under the program for the 1964 crop of wheat. The Secretary may permit producers on any farm to divert from the production of wheat an acreage, in addition to the acreage diverted pursuant to subsection (a), equal to 50 per centum of the farm acreage allotment for wheat: Provided , That the producers on any farm may, at their election, divert such acreage in addition to the acreage diverted pursuant to subsection (a), as will bring the total acreage diverted on the farm to twenty-five acres. Such program shall require (1) that the diverted acreage shall be devoted to conservation uses approved by the Secretary; (2) that the total acreage of cropland on the farm devoted to soil-conserving uses, including summer fallow and idle land but excluding the acreage diverted as provided above, shall be not less than the total average acreage of cropland devoted to soil-conserving uses including summer fallow and idle land on the farm during a representative period, as determined by the Secretary, adjusted to the extent the Secretary determines appropriate for (i) abnormal weather conditions or other factors affecting production, (ii) established crop-rotation practices on the farm, (iii) participation in other Federal farm programs, (iv) unusually high percentage of land on the farm devoted to conserving uses, and (v) other factors which the Secretary determines should be considered for the purpose of establishing a fair and equitable soil-conserving acreage for the farm; and (3) that the producer shall not knowingly exceed (i) any farm acreage allotment in effect for any commodity produced on the farm, and (ii) except as the Secretary may by regulations prescribe, with the farm acreage allotments on any other farm for any crop in which the producer has a share: Provided , That no producer shall be deemed to have exceeded a farm acreage allotment for wheat if the entire amount of the farm marketing excess is delivered to the Secretary or stored in accordance with applicable regulations to avoid or postpone payment of the penalty: And provided further , That no producer shall be deemed to have exceeded a farm acreage allotment for any crop of wheat if the farm is exempt from the farm marketing quota for such crop under section 1335 of this title . The producers on a new farm shall not be eligible for payments hereunder. The Secretary shall provide for the sharing of payment among producers on the farm on a fair and equitable basis. Payments may be made in cash or in wheat. (c) Adjustment of payments The Secretary may provide for adjusting any payment on account of failure to comply with the terms and conditions of the land-use program formulated under subsection (b) of this section. (d) Advance payments Not to exceed 50 per centum of any payment to producers under subsection (b) of this section may be made in advance of determination of performance. (e) Diverted acreage used for production of certain crops; rate of payment; limitation on rate The Secretary may permit all or any part of the diverted acreage to be devoted to the production of guar, sesame, safflower, sunflower, castor beans, mustard seed, crambe, plantago ovato, and flaxseed, if he determines that such production of the commodity is needed to provide an adequate supply, is not likely to increase the cost of the price-support program and will not adversely affect farm income, subject to the condition that payment with respect to diverted acreage devoted to any such crop shall be at a rate determined by the Secretary to be fair and reasonable taking into consideration the use of such acreage for the production of such crops: Provided , That in no event shall the payment exceed one-half the rate which otherwise would be applicable if such acreage were devoted to conservation uses. (f) Additional terms and conditions The program formulated pursuant to subsection (b) of this section may include such terms and conditions, including provision for the control of erosion, in addition to those specifically provided for herein, as the Secretary determines are desirable to effectuate the purposes of this section. (g) Regulations The Secretary is authorized to promulgate such regulations as may be desirable to carry out the provisions of this section. (h) Commodity Credit Corporation funds and authorization of appropriations for payments and administrative expenses The Commodity Credit Corporation is authorized to utilize its capital funds and other assets for the purpose of making the payments authorized in this section and to pay administrative expenses necessary in carrying out this section during the period ending June 30, 1965 . There is authorized to be appropriated such amounts as may be necessary thereafter to pay such administrative expenses.
