Nitrogen Fertilizer Trends in Nebraska from 1955-2023
April 16, 2024
This Nebraska Extension article highlights the impact of factors such as plant genetics and improved production practices to fertilizer consumption in Nebraska over numerous decades.
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.
Nutrient Management Suggestions for Corn Updated in EC117
July 9, 2019
The Nebraska Extension Circular, Nutrient Management Suggestions for Corn (EC117), has been updated to account for residual soil nitrate-N and provide an alternative for determining fertilizer-P rates.
Overall Efficiency of Fertilizer Nitrogen Use for Corn Production in Nebraska
April 3, 2019
How well are we managing N fertilizer in corn and where can we improve to increase economic and environmental benefits.This article looks at sources of N fertilizer losses, input efficiencies and other factors.
Nitrogen Inhibitors for Improved Fertilizer Use Efficiency
January 14, 2019
This article looks at how some nitrogen inhibitors temporarily reduce populations of Nitrosomonas and Nitrobacter bacteria, the soil bacteria responsible for converting ammonium to nitrite and nitrite to nitrate as well as what to look for in product claims.
Profit and Nitrogen Use Efficiency Gain Using Sensor-Guided Fertigation
January 9, 2019
A UNL study of sensor-based and model-informed fertigation treatments confirms that sensor fertigation treatments are consistently the most profitable and efficient methods of applying N compared to current best management practices (BMPs).
Richard Ferguson to Lead Rwanda Institute
December 6, 2018
Richard Ferguson has been named vice chancellor for the Rwanda Institute for Conservation Agriculture (RICA), effective Jan. 1, 2019. Ferguson, professor and interim head of the Agronomy and Horticulture Department, has led research and extension projects related to nitrogen management and soils since joining the university in 1985.
Consequences of Fall-Applied N
November 9, 2018
A fall nitrogen application has a relatively high loss potential and is considered the riskiest N management practice. Consider breaking tradition and splitting your N applications next year to coincide with when your corn most needs more N.
