How Can a Warm Winter and Spring Affect Nitrogen Availability for the Upcoming Crop?

April 3, 2024

With a warmer start to the 2024 growing season, more nitrogen could be available in the soil. To estimate the amount of fertilizer N to apply this year, extension educators review how to conduct a late spring soil nitrate test.

Producer analyzing fertigation system — Beginning July 31, the Sunset Seminar series will give producers across the state a chance to see the results of image-based nitrogen management research conducted by Nebraska farmers in 2023.

Sunset Seminars to Explore Capabilities and Impacts of Image-based Nitrogen Management

July 13, 2023

Free to attend, the Sunset Seminars will provide growers and agronomists a look at results from several Nebraska producers who have trialed Sentinel Fertigation's new N-Time™ software this growing season.

Sensor-based Fertigation Management Research Boosts Efficiency, Profitability

March 9, 2023

Tested on cornfields in eastern Nebraska, the study's sensor-based fertigation produced about 44 pounds more grain per pound of nitrogen than traditional methods, with an increase in profitability ranging from $28-$40 per acre.

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.

UNL Doctoral Student Develops Software Platform to Improve Nitrogen Applications

March 10, 2022

Stansell's research utilized crop canopy image data to apply nitrogen fertilizer more efficiently, and resulted in a 25% boost in efficiency and a savings of 45 pounds of nitrogen per acre.

Tractor in field — 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?

Tips for In-season Nitrogen Management in Corn

April 29, 2020

This spring conditions are good for pre-plant fertilizer, but there are still considerations that justify shifting more nitrogen application to in-season versus pre-plant.
