Nitrogen Recommendation Systems

Nitrogen fertilization for corn production is complicated by soil and weather variability, yet such 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 those strategies. This presentation will present results from side-by-side comparisons of these decision tools for corn production over 8 states in the U.S. Midwest. Such comparison improves understanding of strengths and limitations of different N recommendation tools.
