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.
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.
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 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.
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.
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.
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.
