Studies are getting underway for the 2023 growing season, but there's still time and availability for Nebraska farmers who are interested in conducting on-farm research this year.
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.

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.
Laura Thompson, Nebraska Extension, and Laila Puntel, UNL Department of Agronomy and Horticulture, will present research findings and insights on ag technology and on-farm research during the March 9-11 Commodity Classic in Orlando, Florida. Recordings of their presentations will be available at a later date for those who don't attend in person. (Photo by Craig Chandler, University Communication and Marketing)

Two university faculty members will highlight their research on remote sensing in nitrogen fertilizer management and share insights on what the data-driven “farm of the future” will look like.
A variable rate nitrogen prescription is applied on Monte Murkel’s Nebraska farm as part of a Nebraska On-Farm Research study to evaluate how optimum nitrogen rate varied in his field.

In irrigated or dryland areas with normal production, management practices may continue as normal, but for dryland areas with drastic yield reductions, there is potential for nitrogen fertilizer adjustment for the 2023 crop.
