Tva Fertilizer Patents

This bulletin is a collection of abstracts of patents granted to TVA on fertilizer technology and related topics over about 45 years. It contains 200 patent abstracts that have been divided into 13 major sections. Each section reflects the improved technology through this period of time. Abstracts of some of the patents issued to TVA since 1968 have already appeared in Fertilizer Abstracts, a journal published monthly since 1968. Inventor and subject indexes are provided in this bulletin.

This bulletin is a collection of abstracts of U.S. patents selected from those published in the first 11 volumes of Fertilizer Abstracts. It contains 1014 abstracts selected as the most pertinent U.S. patents for the fertilizer industry today. U.S. equivalents of previously issued foreign patents are included. Defensive publications issued by the U.S. patent office have not been included.

The objective of TVA's fertilizer technology demonstrations is to make results from research, development, and demonstration production programs available to industry to facilitate their adoption. Ultimately the implementation of new and improved technology will improve farm productivity and help minimize production costs for food and fiber.

This evaluation identifies and quantifies many specific benefits of the TVA fertilizer program. These benefits will continue to accumulate. The study also shows that there are current and future opportunities for developing and introducing technologies whose impact on the fertilizer industry, the Nation's farms, and the national economy will be as great as the impact of developments in past years.
