Where are the oldest fertilizer experiments in the United States located?

Probably on Jefferson's farm.
I hate questions like that because the Indians learned to make the soil more productive and even showed the incoming Europeans their methods.

Pennsylvania State College.


I agree, Nora, very often what happened among Native people is just taken for granted. It's like the discussion of "discovery". What do you call it when you've been in a place for 10 or 12 thousand years? Apparently not discovery. If you haven't read a book called Lies My Teacher Told Me, you might find it interesting. I was amazed at the myth we've been taught about Squanto and the Pilgrims. Apparently Squanto could speak English because he had been sold as a slave twice. And Plymouth had been an Indian village right up to the landing of the pilgrims. Apparently it had just been hit by small pox. A quote from Miles Standish in his ships log says they entered the village walking on the corpses of the dead natives. They then moved into the abandoned cabins and took over the crops they found already growing in the abandoned gardens. This would have been the first time they saw corn. It's worth reading the book just to see how the powers that be decide what should go into a history book and what should be left out.
