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.
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).
Researchers Aim to Reduce Nitrogen Fertilizer Use
November 28, 2018
Today’s agricultural researchers are turning to plant genomics to find solutions for growing crops more sustainably with fewer inputs, including nitrogen fertilizer, without sacrificing yield or profit.
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.
Is Late Season N Fertilization Warranted for Irrigated Soybean in Western Nebraska?
November 2, 2018
On-farm research trials were conducted in three southwest Nebraska counties to study whether a late season N application during the pod setting and seed filling phases would increase soybean yields.
It’s Not Too Late to Plant Cereal Rye as a Nitrogen Catch Crop Before Soybean
October 24, 2018
In trials conducted at three research stations in eastern, northeastern and south-central Nebraska, researchers investigated rye productivity and its ability to scavenge N when grown as a cover crop between full-season corn and soybeans.
