16 U.S. Code § 590g - Additional policies and purposes of chapter
(a) Purposes enumerated
It is hereby declared to be the policy of this chapter also to secure, and the purposes of this chapter shall also include,
(4) the protection of rivers and harbors against the results of soil erosion in aid of maintaining the navigability of waters and water courses and in aid of flood control;
(5) reestablishment, at as rapid a rate as the Secretary of Agriculture determines to be practicable and in the general public interest, of the ratio between the purchasing power of the net income per person on farms and that of the income per person not on farms that prevailed during the five-year period August 1909–July 1914, inclusive, as determined from statistics available in the United States Department of Agriculture, and the maintenance of such ratio;
(6) prevention and abatement of agricultural-related pollution,  and
(7) the promotion of energy and water conservation through dry land farming. The powers conferred under this section and sections 590h, 590i, and 590j to 590n of this title shall be used to assist voluntary action calculated to effectuate the purposes specified in this section. Such powers shall not be used to discourage the production of supplies of foods and fibers sufficient to maintain normal domestic human consumption as determined by the Secretary from the records of domestic human consumption in the years 1920 to 1929, inclusive, taking into consideration increased population, quantities of any commodity that were forced into domestic consumption by decline in exports during such period, current trends in domestic consumption and exports of particular commodities, and the quantities of substitutes available for domestic consumption within any general class of food commodities. In carrying out the purposes of this section due regard shall be given to the maintenance of a continuous and stable supply of agricultural commodities adequate to meet consumer demand at prices fair to both producers and consumers.
 So in original. The comma probably should be a semicolon.
