S Illinois | I wouldn't trust those two any further than I could throw them. Mulvaney was upset that the crop science dept didn't back his "Illinois Soil Nitrogen Test (ISNT)" testing at Champaign and he decided to go off on a tangent. The data they pulled was cherry picked. I trust Emerson a whole lot more than those two.
