Corn Split Nitrogen Application

This decision support tool can help farmers and farm advisors understand the risks and benefits of using post-planting nitrogen (N) application for corn production. The Corn Split N tool combines historical weather and fieldwork data with economic considerations to determine the feasibility and profitability of completing a second (split) N application within a user-specified time period. 

This tool may help users with decisions that can:

• increase corn yield,
• reduce nitrogen costs,
• reduce nitrogen losses to the environment, and
• affect the likelihood of completing in-season fieldwork.

Users can quantify the costs and benefits of post-planting nitrogen applications for their farming operation to help both the bottom line and the environment.

The tool is one of the AgroClimate Tools, many of which were developed through the Useful to Usable (U2U) project.
