Determining which corn nitrogen (N) fertilizer rate recommendation tools best predict crop N need would be valuable for maximizing profits and minimizing environmental consequences. To assist farmers with corn N rate decisions, multiple publicly available recommendation tools have been developed over the years. With the numerous tools available to farmers, the question arises: which of these tools consistently recommend N rates closest to the economically optimal N rate (EONR)?
