It is declared to be the policy of the Congress to promote the efficient production and utilization of products of the soil as essential to the health and welfare of our people and to promote a sound and prosperous agriculture and rural life as indispensable to the maintenance of maximum employment and national prosperity. It is also the intent of Congress to assure agriculture a position in research equal to that of industry which will aid in maintaining an equitable balance between agriculture and other sections of our economy. For the attainment of these objectives, the Secretary of Agriculture is authorized and directed to conduct and to stimulate research into the laws and principles underlying the basic problems of agriculture in its broadest aspects, including but not limited to: Research relating to the improvement of the quality of, and the development of new and improved methods of the production, marketing, distribution, processing, and utilization of plant and animal commodities at all stages from the original producer through to the ultimate consumer; research into the problems of human nutrition and the nutritive value of agricultural commodities, with particular reference to their content of vitamins, minerals, amino and fatty acids, and all other constituents that may be found necessary for the health of the consumer and to the gains or losses in nutritive value that may take place at any stage in their production, distribution, processing, and preparation for use by the consumer; research relating to the development of present, new, and extended uses and markets for agricultural commodities and byproducts as food or in commerce, manufacture, or trade, both at home and abroad, with particular reference to those foods and fibers for which our capacity to produce exceeds or may exceed existing economic demand; research to encourage the discovery, introduction, and breeding of new and useful agricultural crops, plants, and animals, both foreign and native, particularly for those crops and plants which may be adapted to utilization in chemical and manufacturing industries; research relating to new and more profitable uses for our resources of agricultural manpower, soils, plants, animals, and equipment than those to which they are now, or may hereafter be, devoted; research relating to the conservation, development, and use of land, forest, and water resources for agricultural purposes; research relating to the design, development, and the more efficient and satisfactory use of farm buildings, farm homes, farm machinery, including the application of electricity and other forms of power; research and development relating to uses of solar energy with respect to farm buildings, farm homes, and farm machinery (including equipment used to dry and cure crops and provide irrigation); applied research to develop agricultural, forestry, and rural energy conservation and biomass energy production and use; research relating to the diversification of farm enterprises, both as to the type of commodities produced, and as to the types of operations performed, on the individual farm; research relating to any other laws and principles that may contribute to the establishment and maintenance of a permanent and effective agricultural industry including such investigations as have for their purpose the development and improvement of the rural home and rural life, and the maximum contribution by agriculture to the welfare of the consumer and the maintenance of maximum employment and national prosperity; and such other researches or experiments bearing on the agricultural industry or on rural homes of the United States as may in each case be deemd ¹ advisable, having due regard to the varying conditions and needs of Puerto Rico, the respective States, and Territories. In effectuating the purposes of this section, maximum use shall be made of existing research facilities owned or controlled by the Federal Government or by State agricultural experiment stations and of the facilities of the Federal and State extension services. Research authorized under this section shall be in addition to research provided for under existing law (but both activities shall be coordinated so far as practicable). For purposes of this title,² the term "solar energy" means energy derived from sources (other than fossil fuels) and technologies included in the Federal Non-Nuclear ³ Energy Research and Development Act of 1974, as amended [42 U.S.C. 5901 et seq.].
