| It's hard to find, but I think you can download from this link where the original source material came from. Louis M. Thompson, an ISU professor, originally published it in the 1980s- so it predates both the big 2010-2012 commodity boom and our present day situation. There's some other very interesting work of his I've found regarding weather, cycles, and crop production while it's raining this morning, might make a new post about some of it later.
