For producers planting corn-on-corn this growing season, Nebraska Extension encourages taking soil samples to determine accurate nitrate levels and adjusting N application rates accordingly, as there may be considerable amounts of residual nitrogen left from the previous corn crop.

Understanding Soil Residual Nitrogen and its Dollar Value for Next Crop

March 14, 2023
For producers planning corn-on-corn this growing season, there may be a substantial opportunity to reduce nitrogen fertilizer applications, as drought and reduced yields likely left higher-than-normal residual N in many fields.
