Determine your optimal nitrogen rate using the N-FACT

May 8, 2025

Your ideal nitrogen rate varies from year to year based on weather trends and field-specific conditions. Before applying in-season nitrogen, explore how utilizing the Nitrogen Fertilizer Application Consultation Tool (N-FACT) can improve the nitrogen efficiency of your fields.

Iowa Soybean Association Senior Research Agronomist Alex Schaffer and Premier Crop Systems Agronomic Information Advisor Molly Haub join Andy Petersen to discuss how farmers are using the N-FACT tool to determine nitrogen application rates using field-specific scenarios. Discover how this free tool can improve crop performance and boost return on investment by determining a field’s optimal nitrogen rate using data from the Iowa Nitrogen Initiative.

Try it for yourself. Visit n-fact.ag to determine your recommended nitrogen rate before making in-season application decisions to maximize your nitrogen investment.
