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?

Anticipated high residual soil nitrate-N levels in NE rainfed crops of dry 2020 can be credited to reduce N rates for 2021

Planning 2021 Fertilizer-N Application Following a Dry 2020

October 6, 2020
Fertilizer-N is a big investment for crop production in Nebraska and elsewhere. After harvest, growers tend to plan their fertilizer-N management for the next year’s crop. But the question is how much nitrogen can they apply to get the most profit from their fertilizer-N investment?

How Much Nitrogen Does My Cover Crop Take Up and When Do I Get It Back?

August 27, 2020
Biomass production, N uptake, and C:N ratio vary widely across the United States. The N in cover crop biomass will be released within a few weeks after termination, however, decomposition varies with soil moisture, soil temperature and C:N ratios.
