With the USDA projecting a higher season-average corn price for 2026/27, planting corn on corn may make economic sense for some operations. But continuous corn requires more than simply planting the same crop another year.
Higher residue levels, increased pest and disease pressure and greater nitrogen requirements can all affect profitability. Before committing acres to continuous corn, consider how your management program will need to change.
Benefits of corn-on-corn rotation
Profitability with high demand and commodity prices
Current projections put the 2026/27 season-average corn price at $4.50 per bushel, up from $4.15 in 2025/26. Strong export demand and continued corn use for ethanol are contributing to higher projected prices, which may make planting continuous corn economically attractive for some growers.¹ However, those potential returns should be weighed against the additional management and input costs associated with corn-on-corn production.
Challenges of continuous corn
Corn-on-corn yield drag
Unless specific measures required for continuous corn have been applied, corn-on-corn typically produces a lower yield than corn following soybeans or alfalfa. This phenomenon is known as the continuous corn yield penalty (CCYP) and can result in 20-30 bushel yield losses compared with rotated fields.²
Hybrid selection is one place to start addressing that risk. Look for hybrids with strong seedling vigor, defensive disease packages and performance characteristics suited to higher-residue environments.
Increased disease and pest risks in corn-on-corn rotations
Planting continuous corn quickly builds residue, especially in corn-on-corn no-till fields. That residue can harbor overwintering pests and pathogens, increasing the risk of yield loss as corn is planted year after year.
Wireworms and white grubs can threaten seedlings, while corn rootworm and European corn borer may become more significant concerns during the season. Seed treatments can help protect seedlings, while Bt traits can provide additional protection against specific insect pests.
Corn rootworm requires particular attention in continuous corn. An integrated management approach can include appropriate Bt traits along with Nurizma® soil insecticide applied at planting.
Fungal diseases such as gray leaf spot, tar spot, northern corn leaf blight and anthracnose leaf blight can also become more severe in corn-on-corn systems. Selecting hybrids with strong disease packages and managing residue can help reduce risk.
Planting challenges in no-till corn on corn
Heavy residue can interfere with planting by keeping soils cooler and wetter and making it more difficult to achieve consistent seed placement. Damp residue can also be difficult for disk openers to cut cleanly.
Properly adjusted row cleaners can help clear residue from the seed path. Planter downforce and closing systems should also be matched to field conditions to maintain consistent seed depth, furrow closure and seed-to-soil contact without creating excessive compaction.³
Increased input cost
Continuous corn generally requires more nitrogen than corn following soybeans, in part because decomposing corn residue can temporarily immobilize nitrogen. That additional requirement becomes more important when nitrogen prices are high.
Nitrogen fertilizer prices increased substantially in 2026. University of Nebraska-Lincoln Extension reported retail urea bids rising roughly 20% to 30% during one period in the spring, increasing the importance of nitrogen-use efficiency. Rather than making across-the-board cuts, growers should use current corn and nitrogen prices, regional recommendations, soil nitrogen credits and in-season diagnostics to determine an economically appropriate nitrogen rate.⁴
Continuous corn can capitalize on favorable corn economics, but success depends on managing the additional agronomic and input-cost risks. Choosing appropriate hybrids and adjusting pest, residue, planting and nitrogen management can help determine whether corn on corn makes sense for your operation.
Experts are available to help you make your continuous corn management decisions. Reach out to your seed retailer, a nearby extension office agent, or a seed company professional like your regional BASF representative.
