Discover the philosophical and scientific roots of sustainable, regenerative agriculture through readings dating from the 1500s. Below are selected resources from the National Agricultural Library's Tracing the Evolution of Organic/Sustainable Agriculture (2007 updated and expanded; archived) and (1988, archived)
Five Hundred Points of Good Husbandry. Tusser, Thomas (1524?-1580). London: H. Denham, 1580. 4p., 289 numbered leaves, 2p. Complete title: Fiue hundred pointes of good husbandrie, as well for the champion, or open countrie, as also for the woodland, or seuerall, mixed in eurie month with huswiferie, ouer and besides the booke of huswiferie, corrected, better ordered, and newly augmented to a fourth part more, with diuers other lessons, as a diet for the farmer, or the properties of winds, planets, hope, herbes, bees, and approoued remedies for sheepe and cattle, with many other matters both profitable and not vnpleasant for the reader: also a table of husbandrie at the beginning of this book: and another of huswiforie at the end: for the better and easier finding of any matter contained in the same. In verse.
NAL Call no: 30.8 T87 1580
Annotation: This classic has been reprinted almost every century since its original publication. Tusser’s maxims include observations of human behavior - “Still crop’ upon crop many farmers do take and reap little profit, for greediness sake... 11, observations concerning the land” and “land (overburdened) is clean out of heart,” or “if land be unlusty, the crop is not great.” He also gives advice by the month, frequently in rhyme. “Octobers Abstract” is about the rotation of crops: “Where barlie did growe, laie wheat to sowe, yet better I thinke, sowe pease, after drinke. And then if ye please, sowe wheat after pease.” [Annotated by Jane Potter Gates]
Organic Chemistry and its Application to Agriculture and Physiology. Liebig, Justus Freiherr von (1803-1873). London: Taylor and Walton, 1840. 407p. Edited from the manuscript of the author by Lyon Playfair. Translated from the German, Organische Chemie in ihrer Anwendung auf Agricultur und Physiologie. Includes bibliographical references.
NAL Call no: 395 L62O
Annotation: Liebig’s work established basic chemical requirements for agricultural production and plant nutrition. His discoveries, coupled with those of Sir Humphrey Davy (Elements of Agricultural Chemistry, 1813) reduced the soil-plant relationship to chemical reactions and an agricultural “revolution” was begun. By the 1940s, large-scale use of synthetic chemical fertilizers had become mainstream. Liebig’s legacy marks the divergent paths of “conventional” and organic agriculture. [Annotated by Mary V. Gold.]
The Field Book of Manures, or, the American Muck Book: Treating of the Nature, Properties, Sources, History, and Operations of All the Principal Fertilisers and Manures in Common Use, with Specific Directions for Their Preparation, Preservation, and Application to the Soil and to Crops; as Combined with the Leading Principles of Practical and Scientific Agriculture; Drawn from Authentic Sources, Actual Experience, and Personal Observation. Browne, Daniel Jay (1804-1867?). New York: C.M. Saxton and Company, Agricultural Book Publishers, 1855 (oldest edition held by the National Agricultural Library). xii, 5, 422p. Illustrated with engravings.

Annotation: “We shall decide whether their [our children] lives, on the average, are to be lived in a flourishing country, full of all that helps to make men comfortable, happy, and strong, and effective, or whether their lives are to be lived in a country like the miserable outworn regions of the earth which other nations before us have possessed without foresight and turned in to hopeless deserts. We are no more exempt from the operation of natural laws than are the people of any other part of the world.” p. 12. Pinchot addresses not only the status and future of forest and soil resources in the United States, but “Waste through piecemeal planning” and the “Danger of monopoly.” [Annotated by Mary V. Gold.]
