DuPont Cellulosic Ethanol Corn Stover Harvest Program

From feedstock to fuel, sustainability drives DuPont’s cellulosic ethanol programs.

An exciting new tool for your residue management toolbox.

DuPont is contracting with growers to harvest, store and deliver corn stover to the DuPont cellulosic ethanol plant in Nevada, Iowa. Qualified growers must meet the following criteria:

  • Located within a 30-mile radius of Nevada, Iowa
  • Corn acres must be grown in a no-till or conservation tillage system, yield 180 bushels per acre or higher and be on relatively flat land with a slope of 4 percent or less.

Managing Corn Residue for Increased Profit Potential

Higher corn yields have resulted in a higher level of residue, which can pose a challenge for growers. Excess residue harbors disease, interferes with planting, impedes stand establishment and monopolizes nitrogen. Removing a portion of corn stover from high-productivity fields before planting can improve establishment, growth and yield.


  • The corn stover harvest program can help growers manage residue better than most current practices.
  • The time requirement and hassle of residue management practices are reduced or eliminated.


On-farm research in Iowa showed an additional 5.2 bushels per acre on average for fields replanted to corn after partial stover harvest the preceding fall.


  • In high-yield corn production, corn stover production often exceeds the minimum amounts needed to maintain soil health and productivity.
  • Partial stover harvest makes corn production and ethanol production more sustainable.
