I think a lot of them are hooked up with their state's Ag college somehow. I know i was told something about it in school, but I wasn't interested enough to really study more than enough to pass whatever test it was on.

State extension services are actually a cooperative with UGA. I'll use them if I need a basic test (still have to pay but it's usually under $20) but if I want a more complete analysis I send off to a testing company.
