More acres planted to corn and higher plant populations on those acres equals more corn stover. At a recent field day in St. Joseph, Mo., sponsored by the Missouri Corn Growers Association, experts discussed ways to manage the entire extra crop residue.
MCGA has been researching corn stover for past four years, according to Aimee Cope, MCGA field service representative. Feed use, co-generations, and liquid fuels are three opportunities for stover use in Missouri, Cope said.
“We have over 3 millions acres of corn planted in Missouri and from that we have the potential for about 6 million ton of biomass,” Cope said.
Too much crop residue affects seed-to-soil contact at planting and disease levels in the field, according to Steve Petersen with Monsanto. This is particularly true in corn-on-corn production. Petersen said there is a corn residue yield penalty in high-yielding corn on corn without stover removal.
