Applying nitrogen to corn at recommended rates is critical to maximize economic returns, minimize environmental losses and conserve energy, says John Sawyer, ISU Extension soil fertility specialist and agronomy professor.
In an effort to increase awareness of farm energy conservation practices, Iowa State University Extension has released a publication titled, Energy Conservation in Corn Nitrogen Fertilization. This publication shows the energy consumed during the production of nitrogen versus phosphorus and potassium fertilizers. It also provides resources to determine recommended nitrogen application rates for corn, such as the online Corn Nitrogen Rate Calculator from ISU’s Department of Agronomy.
