Interpretive Summary:

Technical Abstract: Nitrogen fertilization for corn production is complicated by soil and weather variability, yet has far-reaching economic and environmental implications. To address this challenge, alternative N management strategies have been explored extensively in recent years by both public and private groups for determining the most consistently-correct N fertilizer rate. Existing as well as new technologies and decision tools are being employed to obtain and process information that facilitates N management strategies. This presentation will provide results from side-by-side comparisons of a number of decision tools for corn production tested in the 2014 and 2015 growing seasons across 8 U.S. Midwest states. Such comparison improves understanding of strengths and limitations of each of the different N recommendation tools.
