Harvest delays caused by the onslaught of wet and unusually cold October weather are adding another stress to this year's predicted near record no-till corn crop.

CANFA executive officer Neville Gould led the group to three sites where work is being done on stubble management, cover and pasture cropping.

Properly handling the residue at harvest is key to preparing for the next crop.

An area farmer told University of Nebraska Extension educator Jim Schneider that he recently received an offer to buy his corn residue for as much as $20 a ton or $60 an acre for a 3-ton harvest.

How much corn crop residue, or stover, can be removed for biofuels without harming soil? An Agricultural Research Service (ARS) study of a 10-mile circle around the University of Minnesota's Morris campus offers some clues.

The possibility that some Bt-containing corn hybrids have higher lignin content than their non-genetically modified counterparts represents an unintended effect with no known mechanism, says Michael Lehman of the USDA-ARS-North Central Agricultural Research Lab in Brookings, S.D.
