Introducing the Nitrogen Fertilizer Application Consultation Tool, a product of the Iowa Nitrogen Initiative.
N-FACT is an online tool powered by INI trials data and the Agricultural Production Systems sIMulator (APSIM), an advanced cropping systems model. N-FACT allows users to select inputs based on their farm and management decisions, including location, crop rotation, growing season precipitation, post-harvest soil nitrate, planting date, and market prices for corn and nitrogen. Based on these inputs, N-FACT outputs probability-based ranges of optimum N fertilizer rates.
N-FACT also hosts an INI trial data explorer that allows users to observe, benchmark, and compare optimum nitrogen rates across different locations, years, and managements. It can be accessed at .
Together, these tools provide new information that allows users to improve nitrogen management for productivity, profitability, and environmental performance
