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.
Fertilizer Recommendations for Soybean Updated
January 10, 2019
The most substantial revisions to NebGuide 859 are in the sections addressing fertilizer nitrogen and iron.
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).
Fertilizer P for Corn: Update of Research Findings and Revised Recommendations
January 9, 2019
Results of research conducted since 2000 to address fertilizer phosphorus (P) for corn will be reviewed. The current fertilizer P recommendations for corn will be discussed and revised recommendations presented at the 2019 Crop Production Clinics.
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.
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.
Nitrogen Fertilizer Stabilizers in Corn
April 19, 2018
Understanding how the three types of nitrogen stabilizers work can be helpful in deciding whether to add one to your spring application. Short- and long-term studies in Nebraska offer insight into how they performed across multiple years. Now, if you only knew how many inches of rain you'd get the first six weeks after application.
Improving the Efficiency of Applied Organic N
April 11, 2018
University of Nebraska research is offering new insights into plant use efficiency of organic N resources such as livestock manure, municipal bio-solids, and others. The studies continue through 2018 and are expected to influence changes in university recommendations.
