Meeter says there are test labs throughout Illinois and surrounding states with ADM in Quincy and Agri King in Fulton, Illinois being certified with the National Forage Testing Association.

By all means, Meeter says, do not feed any drought-stressed corn to livestock before knowing the test results.
