Carrying capacity: Robertson 2012b:339–46; Mallet 2012; Sayre 2008; Kingsland 1995 (1985), chaps. 3–4. The concept originated in Chapman 1928. Leopold’s prime example of carrying capacity, a study of deer, has been heavily criticized (Caughley 1970).
Vogt and carrying capacity: Sayre 2008:130–32 (“The neo-Malthusian use of carrying capacity appears to have its origins in the book Road to Survival,” 130); Vogt 1948:16–45 (quotes, 16); letter, W. Vogt to A. Leopold, 16 Apr 1947, ALP. Osborn, by contrast, a straight-up Malthusian, warned that overbreeding would overwhelm food and water supplies. To ecologist/activist Garrett Hardin carrying capacity is “central to all discussions of population and environment” (1993:204).

Work, hoeing thistles, maize harvest: Borlaug interview with Matt Ridley, 27 Dec 04; VIET1: 59–60, 68–69, 74–75, 95 (“horror”). Hoeing Canadian thistles could not be avoided; Iowa banned them as a noxious weed in 1868.

Admissions test: University Calendar, Bulletin of the University of Minnesota 36:3–4 (10 Oct 1933). Because the test was on 24 September, it seems likely that the riot occurred on the weekend of 16–17 September, during the Chicago milk strike.

Additionally contributing to the foundation’s leeriness was that the GEB had been attacked as a Rockefeller plot, and barred by Congress from working with the government. The GEB, founded in 1902, preceded the foundation.

Further pushing environmental degradation, many ejidos could not obtain credit to buy fertilizer, irrigation equipment, or better farm tools, because the new National Bank of Ejidal Credit was undercapitalized (Olsson 2013:332–33).

Borlaug and DDT (footnote): Russell, pers. comm.; Russell 2001:86, 124–48; Kinkela 2011: chap. 1; Perkins 1978; Borlaug 1972; Borlaug. 1973? DDT and Common Sense. Typescript, TAMU/C 002/003[1]009; Knipling 1945. DDT was developed in the 1930s, after a Geigy researcher accidentally discovered its properties. (The researcher, Paul Hermann Müller, received a Nobel Prize in 1948.) Geigy tried to market DDT in the U.S., only to have its U.S. subsidiary decide in early 1941 that it couldn’t compete against existing insecticides like pyrethrum. Pyrethrum was extracted from chrysanthemum blossoms grown in Asia. When Japanese conquests cut off the Asian chrysanthemum supply, the U.S. military, which feared the loss of troops to insect-borne diseases, directed Agriculture Department researchers to look for a substitute. In November 1942 Geigy sent over samples of DDT, which the government tested, obtaining favorable results. DuPont refused to make DDT unless Geigy gave up its patent rights; strong-armed, the Swiss company caved in; DuPont made a lot of money.
