(a) It is recognized and declared that:
(1) The soil resources and fertility of the land of this State, the economic use thereof, and the prosperity of the farming population of this State are matters affected with a public interest;
(2) The welfare of this State has been impaired and is in danger of being further impaired through failure to conserve adequately its soil resources, and by the decrease in the purchasing power of the net income per person on farms in the State as compared with the net income per person in the State not on farms;
(3) Such evils have been augmented and are likely to be augmented by similar conditions in other states and are so interrelated with such conditions in other states, that the remedying of such conditions in this State requires action by this State in cooperation with the governments and agencies of other states and of the United States and requires assistance therein by the government and agencies of the United States; and
(4) The formulation and effectuation by this State of state plans in conformity with § 7 of the Soil Conservation and Domestic Allotment Act [16 U.S.C. § 590g] is calculated to remedy said conditions and will tend to advance the public welfare of this State.
(b) Therefore, in order to promote the welfare of the people of this State by aiding in the preservation and improvement of soil fertility, in the promotion of the economic use and conservation of land, and in the reestablishment, at as rapid a rate as is 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 net income per person not on farms that prevailed during the 5-year period August 1909 to July 1914, inclusive, as determined from statistics available in the United States Department of Agriculture, and the maintenance of such ratio, the State assents to and accepts the Soil Conservation and Domestic Allotment Act [16 U.S.C. § 590a et seq.] and adopts the policy and purpose of cooperating with the government and agencies of other states and of the United States in the accomplishment of the policy and purposes specified in § 7 of said act; subject, however, to the limitations that:
(1) The powers conferred in this chapter shall be used only to assist voluntary action calculated to effectuate such purposes;
(2) In carrying out the purposes specified in this section due regard shall be given to the maintenance of a continuous and stable national supply of agricultural commodities adequate to meet consumer demand at prices fair to both the producers and consumers.
