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.
Nutrient Management Issues for 2019
March 29, 2019
The impact on soil nutrient availability after the March snowmelt/heavy rainfall event is highly variable. The following describes what to consider in areas of little, moderate, and severe harmful effects.
Poultry Manure Reduces Nitrate Loss to Water in Iowa Study
March 6, 2019
Iowa State University researchers concluded from a long-term field study that poultry manure, when applied at a rate to meet crop nitrogen (N) requirements, can reduce nitrate loss and achieve equal or better yields in corn-soybean production systems.
Effects on Profitability and Nitrogen Loss from Reducing N Rate for Corn
February 5, 2019
This study looks at how various reductions in nitrogen application rates in corn might reduce nitrogen loss to the environment and what the costs of those changes would be in yield and profit.
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).
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.
