A multi-year study of organic N used in Nebraska crop production validated sensor guided in-season N application as a means to efficiently use the N available from manure and other organic materials. See what benefits they found, as well as considerations for use.
This article addresses nitrogen application options for corn and availability of P and K from land-applied grain and fodder damaged by flooding. It supplements the previous article, Nutrient Management Issues for 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.
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).
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.
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.
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.
