In most fields, corn residue remaining after grain harvest is incorporated into the soil with tillage or is left on the soil surface. Currently, corn residue is being harvested by some livestock producers, and there is interest in producing ethanol from corn residue in the near future (Perlack et al., 2005). However, soil productivity (synonymous with soil carbon) will be reduced if all corn residue in a field is harvested regularly and there is not another source of carbon being returned to the soil to replace the carbon removed with the residue.

Energy costs for corn drying and cooling
The purpose of this brief article is to provide enough information so that readers can estimate costs for drying and cooling corn. Grain needs to be dry to be stored through warm weather and it takes some energy to remove moisture from grain, but there are things that can be done to manage energy use.
