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

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.
Cover Crop and Crop Residue Management: How Does it Affect Soil Water in the Short and Long Term?
August 13, 2018
How you manage your soil today impacts its productivity tomorrow. This article focuses on how plant residue management and cover crop use affect water infiltration and plant available water.
Crop Residue and High-Carbon Char: Potential Soil Conservation Tools
May 8, 2018
Soil is the single most important resource on which our agriculture depends. Proper soil management is necessary to sustain long-term agricultural productivity. Soil loss through erosion or run-off hurts agricultural production with depletion of organic matter and fertility. It also has environmental implications.
