Considerations for In-season Nitrogen Management in Corn

March 30, 2022
Most areas in Nebraska likely haven't had significant nitrogen losses to already applied nitrogen, but unfavorable soil conditions during nitrogen application and precipitation in April could lead to additional losses.

Anticipated high residual soil nitrate-N levels in Nebraska rainfed crops of dry 2020 may allow reduced N rates for 2021.

Q&As on Nitrogen Investment in Corn This Year

March 31, 2021
Most of Nebraska was drier than normal in 2020, which means a potential increase of residual nitrate-N. As such, producers may need to reduce fertilizer-N rates for 2021 — but how much is enough?
