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. [archive.org] 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.

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.]

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.]
