Interpretive Summary:

Technical Abstract: Improving corn (Zea mays L.) N management is pertinent to economic and environmental objectives. However, there are limited comprehensive data sources available to test and improve N management strategies. Therefore, a public-industry partnership was formed to conduct standardized corn N rate response field studies throughout the U.S. Midwest. This research was conducted using a standardized protocol (e.g., at-planting and split N application timings, N rates, N source, and location selection) at 49 site-years across eight states over the 2014 to 2016 growing seasons with many soil, plant, and weather related measurements. This presentation highlights methods, data sources, key findings, and the potential to use this dataset for additional analyses.
